User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36
Steps to reproduce:
Opened firefox and left on Google page. 1 page only open and when I cam back from dinner Firefox was unresponsive. Opening task manager FF was utilising 15GB of memory on the Google search page with nothing else open. Using latest version according to About Mozilla 95.0.2 64bit.
Attached is a memory report. I have done nothing or changed no hardware. Chrome does not do this. Would like to be able to use FF though as it is my preferred browser.
Actual results:
FF freezes and becomes unresponsive. Needs to be killed in task manager due to memory issue.
Expected results:
Everything should work the way it is supposed to.

The Bugbug bot thinks this bug should belong to the 'Core::Performance' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hello, thanks for this bug report. We've notice a lot of heap unclassified memory in your memory report, and are trying to figure out why that is happening. We're missing some key information, is there any chance you could help us fill in the blanks? We'd really like to see any extensions that are being used to see if that is an issue?
If you can go to "about:support" and paste in the information into this bug report as an attachment, it will be very helpful. In addition, if you can do the same with memory, aka "about:memory" that would be helpful.
With those two things, we'll be able to make a better diagnosis. If you've feeling generous, a profile in addition would be most useful, but it might be harder to do in this case due to the memory leak. Here's information on how to do that: https://firefox-source-docs.mozilla.org/performance/reporting_a_performance_problem.html
Thanks!
Not sure if this is what you asked for as I am pretty sure this is the same as the measure and save.
tried to do the profile and received this error.
[Exception... "Out of Memory" nsresult: "0x8007000e (NS_ERROR_OUT_OF_MEMORY)" location: "JS frame :: https://profiler.firefox.com/a59754803c26db8bb165.bundle.js :: nh :: line 158" data: no]

Reduced profile preserved for posterity: https://share.firefox.dev/3qpcxAH
The WebExtensions process main thread is busy 100% of the time, asynchronously spinning while getting data out of ExtensionStorageLocalIDB.
Maybe the extensions database is corrupted?
vader0099, can you try to "refresh Firefox" and re-add your add-ons, and see if the problem still happens?

You have Ant Video Downloader installed. According to its reviews, the latest version of Ant Video Downloader is known to cause this type of issue. (Thanks to gorhill for pointing this out in bug 1749081 comment 3)
Please try disabling Ant Video Downloader and restarting.
Thank-you very much. Disabled and the issue went away. really appreciate the assistance in getting this fixed. Thank you.
