Not sure if this is a Firefox or YouTube bug.. it's really annoying and happens quite a few times each day I use my PC..

Thanks.

I have an issue where my firefox freezes whenever I try to take certain actions inside home assistants music assistant. I have created the following profiler of the issue https://share.firefox.dev/4pPZRPo

I have tried all the recommended settings to mitigate these kinds of problems (remove hardware acceleration, set disable all addons). I don't know where to report this exactly, but I'm hoping someone might be able to see something from the profiler that could illuminate what exactly is going wrong?

Notably this issue does not happen in firefox private mode.

I have removed many gb of apps to try and address this issue today but can't stop Firefox from using an insane amount of memory. What's up? I've been using Firefox for years and have never had this issue until today. I'd like to keep using your browser but I can't if my computer keeps shutting down.

I go to a website and it tells me that it has emailed me a code. I have to go to another app to bring up my email to get the code. When I go back to Firefox using the recent apps feature, on my phone, Firefox reloads to the previous page and I have to start all over again because you've gotten rid of the page I was on, to put the code in. It's an endless cycle. Since I'm not actually closing Firefox why can't it open onto the page I was just on?
