Firefox Community Forum

I often keep many tabs open for research, and Firefox memory usage grows significantly over time. Are there practical settings or habits that help manage memory without sacrificing usability?

I just opened Firefox on my Win 11 pc, and find all my tabs have gone. The setting to reopen last session is active, as before. I think FF updated itself earlier today. I also had occasion to look at it briefly on my synchronised android phone. I would like to: - get my tabs back - find a way to stop this haappening (it's not the first time).

Any advice much appreciated, thanks. Richard

NB - For the past half a year I have to sometimes right click to interact with them, anyway

Effectively, I will interact with the extension at the most basic, normal level on something that has interactive elements like a dropdown menu, or basic options.

I will click / right click on the icon and the highlight will appear, then that's it ... the browser then crashes and does not recover. :(

What's worse is that I have to Force Quit and when I restart there is no crash report to send to Moz.

I am just wondering if other Linux users have experienced similar issues.

The attached image is taken at the moment before the 'Force Quit' dialogue opens up in Debian 12 Gnome (Wayland) ...

I have Hardware Acceleration on.

I am about to start testing with it off, but I work from the browser, and do not want performance compromises. So that is (at best) a work-around, and certainly is not a fix.

I'm on version 147.0.2 (64-bit) which would appear to be from the Mozilla Firefox Debian Package mozilla-deb - 1.0 install/repo/whatever ... and the PC specs are: Processor: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Memory: 32705MB (11893MB used) Resolution: 7680x2358 pixels OpenGL Renderer: Quadro RTX 3000/PCIe/SSE2

These are my media. prefs ... but ... I doubt that it is relevant: media.ffmpeg.allow-openh264 true media.ffmpeg.customized-buffer-allocation true media.ffmpeg.disable-software-fallback false media.ffmpeg.enabled true media.ffmpeg.encoder.cpu-used 7 media.ffmpeg.encoder.enabled true media.ffmpeg.encoder.quantizer-max 35 media.ffmpeg.encoder.quantizer-min 10 media.ffmpeg.vaapi.force-surface-zero-copy 2

I am do not get sound using audio recorded with akamai player with Fire Fox browser. I tried the same link using Edge browser and the audio works.

I have tried clearing the cache, but still no sound.

How do I resolve this issue using Fire Fox as my default browser? Is there an audio extension that is needed?

I picked "performance and connectivity" because I am NOT connecting with you due to your constant Leftist biased performance.

I just thought you might like to know that because you keep posting biased fake Leftist news from CNN, AP, PBS, NPR, Axios, The Guardian, Washington Post, NY Times, etc., on my Firefox home page, I have BLOCKED all your content. I kept dismissing the CNN, etc. content but you kept right on sending it back.

I cannot sign into Discover Card when I use FireFox. I talked to Discover Card about it. They say the most frequent reason it happens is because Discover Card is not on your safe list. I tried signing in on my other PCs with a Ubuntu OS and their browser Opera works fine on signing me in. Within the last two weeks I installed Mint on two of my PCs. works great except for not being able to sign in to Discover Card. I am not having that problem on any other sites. I doubt if my cache is full as my usage being new OS has been minimal. I just tried signiing in with this PC after installing Mint yesterday. I get the same message

"We're sorry. Your request cannot be completed at this time. We sincerely apologize for this inconvenience and are working to resolve this issue soon."

Discover wants to blame Firefox. Personally I think It has to do within the Mozilla VPN. I say that because I often had the same problem when I used McAfee's VPN. Discover maintains it has nothing to do with VPNs and it is a trust issue.

Eventually I want to replace Ubuntu with Mint. But I cannot until this problem is fixed. Opera is also running a VPN when I sign in so this would support Discover Cards theory about Firefox not having Discover on a safe list. I think they have it wrong though. If your site is blocked you are not on Discover's safe list. I wish we could get a meeting of the two minds instead of me trapped in the middle. Hope this helps.

sir, lately i had problems with syncronizing FIREFOX between two computers. seems one has an "old" version. i cannot "install" new versions; i download, but then, how to "install-activate". then i checked on "entry-passwords"...hélas, i do not understand your explanations... the technical terms.... what is the account for... etc. i am 80 years old, and i guess you, the IT community, can't care less.

Using the back arrow key at the top left of the screen is crucial to my daily work. The Alt+Back Arrow key as suggested in your new "short cuts" is not working. The pull down of history shows my Corporate name, which is no help to finding the item I was just working on. How can having this simple function of clicking on the back arrow key be brought back as not having it at this time, makes me start the process of searching all over again, which is time consuming and simply makes no sense.

Thank you

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

For months now, I've been trying to use different websites from Netflix, Spotify, YouTube, and my Google account and Firefox blocks access to all of them. I always get the error message "The page isn’t redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies." I've been forced to use Microsoft Edge for many basic websites and it's really frustrating. Please help.

the browser seems to not render emojis at all anymore instead showing them as blanks browser wide, while other browsers such as chrome and arc and the OS itself are handling it quite well and okay

I'm on windows 11

in the image included, right is chrome on the same website
