Steps to reproduce:

ENVIRONMENT

1. You have to use Windows. I'm using Windows 10.
2. You need to have the Onetab extension installed https://addons.mozilla.org/en-GB/firefox/addon/onetab/
3. If you are using the PocketTube extension, make sure that you're not using the latest version. Do NOT use 10.2.7 use an old version instead like 10.2.6 or 10.1.12. Using PockeTube to reproduce the bug is optional, just that it's much harder to reproduce with the latest version.
4. Make sure the Superfetch aka Sysmain service turned off to ensure that Windows isn't caching any software in the memory before it is launched. You have to restart your computer after disabling it for it to properly come into effect. Make sure the "startup type" is set to disabled (see attached image). Simply changing it from "running" to "stopped" is not sufficent.

You can do this in Computer Management (Windows Key + X) or Services (Windows Key + R then type in services.msc)

STEPS

1. Open a youtube video that is part of a playlist
2. Expand a comment thread in the comments section (to see the replies)
3. Have the video progress to the next video in the playlist once the end has been reached (you can use the seek bar to click near the end of the video)
4. Expand a comment thread in the resulting video
5. Exit firefox
6. Open Task Manager and wait for Crash Reporting to open (and minidump analyser)

Expected results:

Firefox shouldn't have crashed.

Below is an example youtube link you can use, because it has a comment thread in the resulting video and the subsequent video.

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