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.

REPEATING IMAGES involving . Macbook Air M4 Tahoe 26.2

When sliding from the primary Mac screen to another on the same computer the Firefox image (and ONLY that image) is duplicated on each additional screen image loaded making the use of multiple screens virtually useless.

When File Explorer of Windows 11 25H2 tries to access and open an icon-file in the FF (144-64bit) profile's 'shortcutcache' folder, explorer gets Access Denied. The account running Firefox has admin rights.

Looking to the ACL of the profile folder containing the folder 'shortcutcache' show no reason for the blocking. Trying this with a new profile did not help.

Hello, I'm using Firefox 147.0.4 on Windows 11. When I open the Adobe Firefly website and I try to upload a file to the Adobe server using drag and drop or by browsing the Windows file system, nothing happens ... There's no error message, but the file isn't uploaded. Of course, this site works perfectly with Opera or Edge... On the Adobe forums, many users have the same problem with Firefox, and Adobe's response is always the same: change browsers ! Thank you for keeping me informed about the resolution of this problem, as I don't want to change browsers ! My email address is [edited email from community support forum]

For the past few days, I haven't been able to use Google Lens for searches. Why? It used to work, and I haven't changed anything on my computer.

I read the support article about this problem: everything seems fine, Google is definitely my search engine... Can you tell me what I need to do to get it working again? Thank you

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
