Closing a tab doesn't actually close the browser visit

So, after using firefox in the background to browse websites or watch videos I checked my memory usage in firefox with about:memory -> Measure and saw that youtube was consuming a decent amount >2GB (checked the main url when clicking the youtube src, it was the video on that sole tab i was watching and nothing else playing youtube in the bg) so i closed that tab, waited a bit and re-measured but then see that the memory usage for youtube rose about 200MB... and the website for youtube is that same url for the tab that i just closed (when checking the src in the results for Measure). I've been revisiting the about:memory page, reloaded it and re-Measured and youtube is STILL THERE. Even now, 10 minutes later i still see youtube there, with none of my tabs running youtube.

If i close firefox entirely and re-open my tabs then it'll very likely fix it but this has to be a major issue no? I shouldn't have to close the entire browser program just to fix a website visit, which is youtube of all websites.

As of this moment, firefox, with 8 tabs open, is consuming 4,452.99MB (~4.5GB) where 2.5GB is youtube for that page i closed.

I don't know if sharing memory reports from the about:memory page give my cookies away or leave me open to a similar vulnerability so I won't share it unless a dev or similar asks for it but for now, I've included an image showing all the tabs i have open on firefox, 2 windows.

Hello there

I'm running version 146.0.1 (64 bit) on a Windows 10 machine, and I've found that trying to use printscreen now opens Firefox. I cannot discern why, if it's a Windows setting or a keyboard issue or anything else

things I've tried:

- Disabling every extension - Disabling AMD Radeon - Disabling ShareX (My normal screenshot program) - Factory resetting my Keychron Q6 Max (in case there's some weird macro that got set up)

Any ideas? This might not be a firefox issue, but I figured I'd ask here. Thank you

I just installed Mozilla VPN but when it's active my internet connection stops working. Pretty sure whatever protocol it's using is the problem with the WIFI signal, but I can't find how to change the protocol like every other VPN service allows. How do I change the VPN protocol? There is strangely no article already on this site for this common problem.

Hiya.

So if I download an attached file on gmail using Firefox... it crashes. If I open up a new tab on Firefox... it crashes. It only started this week.

I'm using 12.7.6 and I really don't want to go back to Chrome, so I hope you can help.

The macbook completely freezes apart from the mouse pointer which moves, but cannot open a thing. Every time I have to turn the macbook off to restart it.

I tried uninstalling and reinstalling the latest version.

Best, Mike
