Firefox Community Forum

Firefox locks up and crashes on Win 10 desktop after it Firefox updates. If I refresh Firefox it seems to work OK for a couple weeks until Firefox updates . Then it becomes unuseable again. I have refreshed firefox twice now. Should I get this ESR version?

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!

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.

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?  :)

About 4-6 weeks ago Chase started throwing an error message when I tried to log in. Some other banks, credit agencies, brokerage houses also same thing. The work with Chrome and Edge.

Can Mozilla get past this or do I give up and use a predatory browser?

As much as I hate ads on YouTube I don't want Firefox to block the ads because if they find out you are blocking ads they will block you from Google and YouTube. I have Google pages and other things on their sites that have been there for years. Plus, I feel like I'm stealing a service by not lets the ads run that pays their bills and the content creators on YouTube. Please tell me where in Firefox I can turn the ads back on.

I have used Mozilla products since Netscape Navigator came out in 1995 I think it was. I went to a local internet provider and brought home a 3.5in Diskette and it loaded Netscape Navigator with my info all filled in for email, Usenet, Webpage publishing and a few Bookmarks to get started. I still use SeaMonkey for my email because it still has email addresses from the 1990's. I have Thunderbird for email on my phone. Anyway, thank you for all your work over the years.

Until recent updates gmail worked normally but over the last several updates the screen is now impossible to read. In Safari gmail is still readable, This seems like a settings problem or a bug. Does anyone know if others are having the same problem or how to try to fix it,, or report it?

On my webpages Firefox loads everything except for the images on my individual product pages. They show up fine on other browsers and on my Firefox on Android tablet. This has only happened since the update to "158.0 (aarch64)" which is only on my MacBookAir. The images below show how it looks now and how it should be.

I started to try free 50GB a month Firefox VPN to use the website in Japan (free TV programs only available in Japan but are allowed to watch through VPN). It was working for about a month but now it seems to be blocked. I tried suggested troubleshooting like clearing cash, quitting and opening Firefox, closing VPN, changing location setting and back to Japan etc. Is it because free? It was working when I was subscribing NordVPN. So, it's not the website issue. I would like to know why it is not working now. Thank you
