Even though CPU and GPU utilization is very low during 8K60fps Youtube playback in the Firefox browser on my base M4 Mac mini, the struggles heavily to play this, drops tons of frames, and the video almost stops playing.

8K 30 fps is not problem, and since utilization is pretty low, that doesn't explain the poor performance.

So please optimize 8K60fps Youtube playback on all platforms in the safari browser, but especially on Apple SIlicon Macs.

In Firefox, recently I am unable to download pdf documents. I get the message "download failed". If I request the same download using Chrome, I get the download immediately. But Firefox is my default browser and it's a nuisance. This only started in the past month or so.

I have used Firefox for ages now and love it. I have noticed in the last few months that some functions on some web sites are not able to be accessed. Such as submit, place an order, and the like. I have to use another browser. Is there any reason for this as I really don't like to use any other browser other than Firefox but it seems to be that I have to. Is there some way that I can get around this?

I've used FF for years. The last year, it does not function correctly on about 20% of sites. I suggest focusing on making it compatible, rather than requiring sites that are perfectly coded. I may have to drop FF soon.

My Firefox desktop app recently updated. After it updated, I now cannot access anything by right clicking. When I right click, a giant window of options shows up (see image). It doesn't change no matter what I click on. When I try to select something in the giant window of options, nothing happens. I'm having a very hard time with it, particularly because I can't open links into new tabs now.

Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

I have used Firefox for longer than I care to remember and have never had any problem with it but this morning I switched on my PC and a new AI side bar has appeard on the left and I don't want it. Can you please make it so we can remove it and looking around the internet, I know I'm not the only one with this opinion.

I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

I use Firefox Developer, on many sites, for no apparent reason, the error "Error establishing a secure connection" started popping up (error code: PR_CONNECT_RESET_ERROR. Even on YouTube, where everything was ok before, it's all crap now. HELP PLEASE

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs
