this issue started when firefox just randomly reset my browser a week ago.

whenever i open a pdf in my file explorer, it opens a completely new firefox window under my default-profile. it doesn't open on my currently open/used window.

for context: i have two firefox profiles, 1 for work, and 1 is the default-profile which is "personal"

anyone know a possible solution to this? or why this happened?

The connection was reset

An error occurred during a connection to www.youtube.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Is it possible to add the File Edit History menu to Firefox for Mac? For those of us who have cut our computer teeth on DOS/Winders, not having the standard File Edit Bookmarks... menu makes it hard to navigate your Firefox for Mac application. Even if many of the File Edit commands are not there because Mac does not use anything remotely like the windows commands it would be nice to know exactly where the more standard commands are located on either OS. Commands like New Tab, New Window, Open File, Close Tab, Close Window, Save Page As, Print, Offline, Exit, Cut, Copy, Paste, Recently Closed Tabs\Windows, Bookmarks and Help would be REALLY nice to have their screen location standardized across all Operating Systems that you support with a firefox browser.

BTW... I still have FirefoxSetup-0.9.exe, FirefoxSetup-0.9.1.exe, FirefoxSetup-0.9.3.exe, FirefoxSetup 1.0.exe for windows... Need a copy?  :)

Whenever I use FireFox to watch Twitch, majority of chat just never appears until I refresh the site... It was working good until some month ago...

I use the extension BTTV to get extra emotes on twitch. And it was working perfectly, some say that is the issue, so I removed it to test, but still FireFox is not loading all messages... What can be done to fix this? Just use another browser?

My Macbook Air (M1, 2020) has be moving slowly recently. I wondered if how I'm using Firefox could be contributing. I typically have two Firefox browser windows open, with 5 or 6 tab groups each with several tabs.

In addition and more specifically, I'm wondering if closing (collapsing) a tab group means those tabs won't be contributing to my computer's CPU load. Thank you.

I can access FamilySearch.org using Safari but I've always used Firefox in the past. I updated my Mac Ios thinking it might have been the problem, and my Firefox is up to date, and it's still not working. I can begin a search but then it just stalls and blinks at me. Thank you!

Video Performance and Glitches In FF or Caused by it

Running 158.0 (64-bit) on Windows 11. Running RTX4070 card and when I watch videos in the main browser window I see very little GPU usage. Computer is a dual CPU Dell 7920 Specs at the bottom.

When switching to another tab, and the video pops out into it's own window I notice an increase in GPU usage. Streaming YouTubeTV, no issues with bandwidth to the machine.

The main display is running at 4k. Also the popped out window is maybe 1/4 the size of the full browser size when it's not popped out so I can't understand why a smaller video use more GPU.

In addition I see Firefox sometimes 'glitching' the popped up window's video. It also seems that when watching video in FF it can glitch other sources that also may be active but this may be just anecdotal, need more investigation.
