Chrome developer tools: constant "page unresponsive" messages - google-chrome

When I open a separate Chrome developer tools window in order to look at a page's JavaScript code I get this window in regular intervals:
When I click "wait" the window goes away but comes back soon after.
How can I get rid of this annoying message?
This happens on Chrome 32 on Windows, and on different websites (e.g. http://spiegel.de).

it does seem that the issue is with the 32.0.1700.102 version of Google Chrome.
I've got several users who are experiencing the problem. It only seems to happen when you are working with sites that open popups (the kind you want) such as opening and email in a new window in Google Mail.
Its seams like the latest update may have helped fix the issue(32.0.1700.102 m), or some users are reporting that the v33 beta does not have the issue. https://productforums.google.com/forum/#!msg/chrome/1PgURxP9_-k/It9TupoPEgQJ

google docs on firefox: Saving your changes is taking longer than usual. Editing is temporarily disabled

I am attempting to use google docs with firefox, but am constantly getting this message.
It never goes away.
And if I close the tab all of my work is deleted.
This is a brand new Firefox install.
Is this an attempt to force us back to using chrome with google docs?
I have been a chrome user for many years but was recently forced to switch to firefox because chrome has an intolerable bug on macOS catalina.
I need to use google docs but I can't use chrome because of this chrome bug and now I can't use firefox because of this bug with google docs.
Is there a work-around for the problem?
Chrome allows me to work with local copies of google docs without losing work if I lose my network connection, but I cannot find a similar plugin for firefox.
I tried to reproduce the issue on Firefox, however it seems to work fine at my end without any sort of error or warning popup in saving.
But, Google is known to play nasty with competitors to promote Chrome and it can't be ruled out that it might be a cause too. You can try multiple options, and check which one works.
Possible Solutions:
If you want to trick google into thinking you are browsing on Chrome, change this setting in Firefox as mentioned here!
Try using the Firefox Developer Edition: [Official Link])(https://www.mozilla.org/en-US/firefox/developer/ "Firefox Developer Edition")
If the above options don't work, try switching to Microsoft Edge for a Chrome alternative if the bug is particularly associated with Google Chrome, though they both are based on Chromium, it's worth a try.
Searching through the Google forums, I came across an issue with GDrive not loading in Firefox. https://support.google.com/drive/thread/1987396?hl=en&msgid=22679169
The last comment on the page the user mentions disabling CORS
Find a solution ! When the add-in CORS (Access-control-Allow-Origin)
is enabled impossible to load the google drive page but no problem
when it is deactivated.
Have you tried disabling the CORS? http://testingfreak.com/how-to-fix-cross-origin-request-security-cors-error-in-firefox-chrome-and-ie/
This will happen if you try to copy/paste info from a place that is restricted. Make sure editing is turned on for all users. If it’s not “shared” correctly it will glitch.

Google Chrome developer tools works very slow

Sinсe Google Chrome was updated to 50.x version, it become impossible to work with DevTools. This issue reproduced mostly in "Network" tab. Every time when you click on "request" it takes about 30-40 sec. after that chrome can crash. Tried to delete all extensions, clear cache, and reinstall, but didn't help. Does anybody know how to fix this issue?
I'm running Chrome 50.0.2661.87 m
UPD: The problem may be occurs because of long headers. Try to close response and request headers.
I've been having similar issues for debugging in Chrome versions 50+ on Mac OS X 10.11.3. The only solution I've found so far is to keep the dev tools docked to the right and it seems to be as performant as before. Not the optimal solution, but it works in my case.
Finally, a solution has been found which helped me after such a long time and after so many failed attempts to fix it: Solution on Google Chrome Forums
Go to chrome://flags/#force-color-profile
Change it to sRGB
Since Google does not allow direct links to chrome:// you'll have to insert the colon by yourself, or enter the whole link manually into your toolbar.
My situation was similar, after struggling a while with extreme slow developer tools response I found out the problem was caused by a Chrome extension I had installed for knockoutJs.
So for people experiencing these issues, as part of the initial troubleshooting, try disabling chrome extensions.
I'm using the Version 61.0.3163.79 and I have the same issue that this post talks about.
With some searches I found out that the problem was in the user that I was using. What I tried was to enter int google chrome as guest and the devtools became faster again.
So what I did was:
Check out if debugging using the guest user is faster as it should be.
Logout from the account.
Clean all cache associated to google chrome.
Restart the PC (but i think closing the browser is enough)
Login again in your account.
I hope this could help other people with same problem.
[EDIT:]
I found out that after some time (weeks) the google chrome dev tools will get slower again. So I tried the following solution and it worked:
Open the dev tools
Go to the Sources tab.
Cleaned all watched variables, breakpoints, DOM breakpoint and Event Listeners breakpoint.
[SECOND EDIT:]
After some weeks, the issue came again. What I did was installing the google canary Version 64.0.3249.2 canary (64-bit) and my problems vanished.
For who's that doesn't know what is canary, please check this link.
Google is aware of the problem - https://bugs.chromium.org/p/chromium/issues/detail?id=624097
The problem seems to have vanished in v.53 - they are currently trying to figure out what fixed it. If possible, the fix will be merged back to v.52. But at least they are working on it.
In case others arrive here facing the same issue I had, try changing the Dev tools tab you're looking at to Elements.
I had the "Sources" tab open and Chrome was trying to load enormous assets for that tab, which created a multisecond delay between the console.log() events I created and the display of those logged messages.
Make devtools snappy again by deactivating all breakpoints:
Go to the Sources tab, show the debugger (may be hidden) and hit Deactivate breakpoints.
(Chrome v62.0 on Windows 10)
I've had the same time issue on 54.0.2840.99 m version of Google Chrome.
But switching to Chrome Canary worked !
Reduce size of resource being overridden
Only overriding files with less lines of code worked well for me. I landed here because I was overriding a file which had 35,000 + lines of Javascript.
Further, if your resource is a new one - i.e. it is not included in a script tag or link tag, you can override main html document and add the tag : <script src="/my-new-script.js"></script>. Add the file to your domain-root within the Overrides folder on Chrome:
overriding HTML
then overriding CUSTOM SCRIPT:
Good Luck...
I also face same issue.
I tried unchecked toggle screencast. Now it is working fine.
In my case, I had Local Overrides setup (https://developers.google.com/web/updates/2018/01/devtools#overrides) in Downloads folder which had a lot of files in it and that slowed down devtools.
Setting up overrides in its own seprate directory fixed the slowness.
I sped up Chrome again by doing the following:
Open DevTools -> select Elements tab ->
select nested Computed tab -> under Filter, make sure that Show all is unselected.
select nested Event Listeners tab -> make sure that Ancestors and Framework listeners are unselected.
For me, running Chrome Version 81.0.4044.138 (Official Build) (64-bit) on Ubuntu 18, the problem seems to be the mobile view. When I disable mobile view inspecting becomes really fast again. I think it is caused by touch emulation and other mobile stuff.
To have something similar to a mobile view I move the DevTools dock to the side and resize it until I get the width I need. It is not perfect, but it is useful most of the time.
Besides Chrome, Firefox is much faster when inspecting sites overall, though I didn't use FF because I'm used to specific things on Chrome. Moreover, most of the sites I work with do not trigger these issues on Chrome, in fact, it happens with only one site.
PD: the site that triggers the issue on Chrome Dev Tools has lots of CSS variables. Not sure if that is related.
UPDATE 1 WEEK ago
I was able to use Chrome without issues even in the mobile view by disabling the option "Show media queries"
Go to the network tool and change it without any restrictions. Sometimes this happens if you change mobile settings. Google chrome changes this setting to test mobile device on low internet connection and leaves it that way.

IT Hit WebDAV AJAX Library on Chrome becomes unresponsive

I am experiencing an issue with opening a Microsoft Office Document, using IT Hit WebDAV AJAX library, in latest Chrome 39.0. running on Windows OS. It is a sporadic issue that occurs only in Chrome, and it happens when one opens a document multiple times. Word instance won't start, the page freezes and browser becomes unresponsive, and Chrome suggests killing the page. The only solution is restarting the browser, which solves the issue.
I have tried opening a document in Chrome on Mac OS X, and it is working fine. So are Mozilla and Safari on all operating systems. It seems to be a Chrome + Windows issue only.
Has anyone experienced this issue and is there a fix?
The Microsoft Office plug-in that opens the document displays a warning popup "Some files can harm your computer.", which is a modeless dialog:
If you quickly click on a link that opens the document more than one time the dialog will hide behind the main web browser window. As a result the web browser window is blocked.
You need to switch to that dialog and confirm or reject document opening, otherwise after some time Chrome will ask you if to kill the page or wait.
Note that there is no way to avoid that dialog, this is a built-in MS Office functionality as far as I know.
Chrome will only work good with ITHitWebDAV if the user has got Office 2013 or superior.
Google is blocking all Java applets and NPAPIs now, so good luck with that. I just detect the browser of the user that wants to edit a document, and if it's chrome, I warn him to change to another browser like Firefox with a modal, and that's all.
Very poor support between Chrome and ITHitWebDAV, and no much you can do about it.

Webpage displayed in Incognito, not in regular Chrome

So i have been running into this problem with a lot of Wordpress sites lately, usually occurring when i am logged in as Admin, so i couldn't post here because no one would be able to view the problem. However, i just found a site that it happens on that doesn't require admin creds.
http://www.otisports.com/
When i visit this site in Chrome (Version 34.0.1847.137 m), it just displays a blank page. No errors, just the (what now seems standard) event.returnValue is deprecated. Please use the standard event.preventDefault() instead. warning. I have seen that warning signify problems on the site, but they are usually minor, not to the extent that the above URL displays. However, if i open an Incognito window and visit the site everything works perfectly and there is no warning. Does the Incognito window deal with webpages in a way that is so entirely different that it would cause something like this to happen?
I have been racking my brain trying to figure this out. Can anyone reproduce this? is it a bug in chrome?
EDIT: I just tried to open a bounty on this question and the EXACT same thing happened. In Regular Chrome, nothing happened when i clicked the start a bounty link and i saw various errors Undefined is not a function however in incognito everything worked perfectly. what gives?!
EDIT: Yes, i have cleared the cache, history, cookies, everything, and i still get the same errors. I cant even post a comment on this question because of errors...
I came across the same issue when trying to open evernote.com. It loaded successfully while using incognito mode in chrome. Let me share how I fixed this even though the original post is way too old. But maybe someone can find it useful.
I'm using chrome (Version 73.0.3683.103 (Official Build) (64-bit)) running on Linux Ubuntu 18.04.2 LTS.
I tried disabling all extensions and clearing browser data/cache but nothing worked. PS: Disabling adblock previously worked for me. Yes, I stumbled over the same issue before and whitelisting evernote in adblock solved the issue. But it didn't now.
The following is what worked for me:
Open developers tools (CTRL + SHIFT + J).
Navigate to Applications tab.
Choose Clear storage from the side menu
Hit Clear site data button.
After reading the comments I dug into chrome and saw there was a bunch of extensions still sitting around that were definitely malware and I thought I had previously deleted. Instead of picking through them one-by-one, I just deleted everything, re-installed Chrome, and now everything works great!
I had the same issue. My application was working in Incognito mode and in Firefox but not in Regular Chrome. I even disabled all the extensions but no luck. I eventually cleared the Cached images and files because on developer console I found out that the regular chrome was still picking up the old file due to caching. So as soon as I cleared it, my app showed up like a rocket :)
Try removing any non required extension .
Specifically AdBlock
I resolved the problem post that.
Since on Incognito , extensions are disabled, hence page run as expected.
I resolved this unforeseen issue using following steps.
CTRL + SHIFT + DEL > Clear Browsing Data.
Cookies and other site data
Cached images and files
This is for Chrome Browser.
Open Console (Ctl+Shift+I) first.
Then under the application tab, you will find some options on the left, find out the application there, you will find it at the top.
There you will find Service Workers.
Under Service Workers, there will be three checkboxes. Select Update on reload checkbox and reload again.
I had the same issue after installing React-Sight Extention.
The Page hanged but not in the incognito mode.
Try deleting any recently added or junk extension.
Delete your cache.
That worked for me
I had a similar issue in chrome, in my case the problem was that I could log in to my university library's website only in incognito mode. After some digging, I figured out that Google Translate extension was set to automatically translate any page. When I turned that off and instead selected never translate that specific page, it started working in the usual mode as well.
This is rather an old issue but still happens. None of the solutions recommended here and there did not solve the issue in my case.
I somehow noticed this is related with a -some kind of- corruption on the user profile.
This is how I solved it:
Close all Chrome browsers.
Open a Google page on Chrome.
Sign-out from Google (rigt click your profile picture on a Google page, not on the Chrome itself), and sign-in.
If this doesn't work:
Close all Chrome browsers.
Right click Chrome icon and select Google Chrome.
Delete your Google profile on the "select your profile" page.
Close Chrome.
Open Chrome, sign-in.
uBlock Origin was the culprit in my case. Once I allowed the site in uBlock Origin, pages loaded correctly in normal Chrome.

Chrome emulator tab defaulted on refresh

With Chrome 32.0.1700.77 the new emulator tab is handy except it's the default tab when I refresh my page.
During my standard development workflow, I constantly refresh the page when I make changes. I usually have the console window open at the bottom of the network or source views. But every single time I refresh the page, the Emulators tab takes focus and I can't see the console.
This is truly annoying since the app will fail because of a simple JavaScript typo, but I can't see the console without clicking one more time (to focus the console tab).
Has anyone found a workaround for this?
Combined with the Chrome Developer Tools unresponsive since update 32.0.1700.76 m issue, I would have to say Google really tripped up this release.
Unfortunately there doesn't seem to be a workaround yet. It looks like there has been a bug reported to Google as found on this thread, but no fix has come about yet.
I think the only way (right now) to prevent the console tab from being hidden when needed is to avoid using the emulator or revert to a previous version of Chrome.
Hopefully a fix comes soon!
It's been a while since this post was made, but I came across the same issue recently. When you have the developer toolbar open, the phone icon beside the "Elements" tab should be blue. Clicking that will disable Emulation.
