In Chrome console: What is "detected mammaliaforme"? - google-chrome

I've Googled this and nothing comes up. So this is some new DOM warning that I have discovered completely on my own. WTH is this?...

Seems to be related to a recent LastPass update, although that's as much as I know.

If you check in dev tools you'll see that the warning is related to 'onloadwff.js'. If you click on that file reference and hover the tab for that file in the sources panel you'll see that the tooltip shows it is part of a chrome extension. I can confirm that disabling the LastPass extension resolves the warning.

How to fix broken tooltips in the Sources tab of Chrome debugger (i.e. dev-tools)

For a long time, I have not been able to use tooltips in the Sources tab of the chrome debugger anymore. Today I thought that I found a fix (which I posted below) but now tooltips have stopped working again. So, maybe someone knows how to fix this?
In Settings/General of the debugger I disabled "Show detailed inspect tooltip". Then I reloaded Chrome and enabled "Show detailed inspect tooltip". Somehow, this caused tooltips to work again.
Unfortunately, not long after, tooltips stopped working again.

Chrome console (F12) doesn't show up

Suddenly my Chrome console can't show up any more. I even tried to uninstall and install Chrome, but nothing helps.
Look how it looks without the console:
And this is how it looks when I press F12 to open the console (the same thing if I try to open it via the menu) notice that it pushes the content aside with blankspace and there isn't any console at all!:
F Lock also disables this functionality. Please toggle the F lock state and check.
I suggest you to try this:
Go to %LOCALAPPDATA%\Google\Chrome\User Data\
Rename the folder "Default" to "Backup" or something else
Launch Chrome (it will recreate the Default folder with a blank user profile)
If you don't have any problem after doing this, your user profile is corrupted. When you uninstall Chrome, your user profile is kept, this is why the problem was still here after reinstalling.
If your F12 press alone doesn't open the devtools in the browser then press and hold Fn and then press Esc. It's done!!
Now you will be able to open devtool just by pressing F12.
I had a similar problem. In my case, it was the TrackIR software intercepting F12. So if you have TrackIR, check it is not running.
I just stumbled upon this and fixed it by turning off all extensions, and then turning them back on one by one. It turns out in my case the screen reader extension "Chrome Vox" caused the issue.

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.

Chrome Console Bug When Debugging Javascript

Chrome console tells you what line in the parsed file JavaScript syntax errors are located. Every once in a while, when I click on the link to take me to see the actual code of where the error is, I get a blank screen in the console. If I open up the same page inside Firefox with Firebug, I can see the error code without any issues.
Is this a known error in Chrome? If so, are there any ways to remedy it?
Here is an official list of known issues with Google Chrome. It doesn't seem like that is one of the known issues. I would try again and see if it happens again.
