I'm working on my website, matthewbellanalytics.com, and I have been trying to make some changes to the contact.css CSS of the contact page. I edited the CSS file and the changes that I was seeing offline weren't reflected online.
Specifically, I changed the background-color:blue, which worked offline as seen here:
I then replaced that file on my hostgator server and I double checked that it was replaced correctly by re-downloading the CSS file from my cPanel.
background-color:blue was definitely still part of the code.
But when I view the website online. background-color:blue, is mysteriously not part of the CSS file anymore.
I assumed this must be a caching issue so I cleared the cache on both firefox and chrome, but still no luck. I then tried opening the website on Opera which I haven't done before so there should be no cache. No luck.
The online page still isn't updating to blue, and looks like this:
Check the css file path. In server the path might vary.
I was able to solve it in chrome, but not firefox, by going into the developer tools and disabling the cache from there under the "network" tab. No other method of clearing cache seems to work.
I updated the source code for my html page on a server, but when I refreshed the page in chrome, it didn't update. Then I tried performing a hard refresh and emptying the cache, but it still didn't work. I also tried opening the page in Firefox, which gave me the updated page, but chrome still didn't update the page for another few minutes.
(I'm using Chrome 63 on Windows 7)
Update: it seems that this problem only happens with small files online of at most 5KB or so.
I figured it out: change the extensions from ".html" to ".php".
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.
I am having this problem for long time. Whenever I update my existing stylesheet it not take effect in browser instantly. If I view page source and click on my stylesheet, ex:<link rel="stylesheet" href="assets/stylesheets/theme-custom.css"> recently added codes are not shown. It updates after few hours. This happens both in Firefox & Chrome.
Why this happening? And how can I get rid of it?
Due to performance reasons browser cache loaded css files. So if you update your css you have to clear your cache. You can also reload the page with clearing it by pressing CTRL + R.
At the following linked page you can find approaches how to deliver your css and force browsers to get the current version (like adding timestamps or anything else as parameter):

EDIT:
You can also just disable the caching completely in the settings or developer tools of your browser.
I have come across a strange issue with my company's site, and it seems to only affect my computer. Changes that I have made to the raw HTML are not reflected in my browser (Firefox).
I have taken the following steps to resolving this issue, without any luck:
Ensured that the page was uploaded successfully to the correct directory (downloading the file from the server shows that it is the same file as the one just uploaded).
Cleared my browser history and cache, refreshed the page.
Opened the page in other browsers (IE, and Chrome).
RDP'd into our server and opened multiple browsers that way.
A colleague of mine sits directly across from me and he has opened the page in the same version of Firefox that I typically use and he can see the changes. He and I both work on the site regularly.
The strangest part is that I have made changes to this page before, and they showed on my screen instantly. These changes are still in place and visible, yet some HTML elements that existed before I made those changes do not show on my screen currently (despite still existing in the HTML).
Has anyone else ever experienced such a phenomenon? Is there anything else that I can try in order to resolve this issue?
Have you tried forcing cache refresh? Try it by clicking Ctrl + F5
