Firefox Support Forum

Hello, this is a problem I've been dealing with for nearly 2 months now. Currently using Linux Mint Cinnamon

The browser won't connect to any websites or even try to load them, anytime I search for something it immediately goes to the error page. I've been struggling with internet on my PC for months and all was fixed when I hooked up ethernet, except for Firefox.

I've gone into about:config countless times. I've restarted it twice, I've tried installing the flatpak version and it's exactly the same result. I've deleted it and reinstalled, nothing. I've unchecked everything I've changed in about:config, once again nothing.

I can't update it as for some reason it says it's disabled by system administrator, which I don't remember enabling. I checked the firewall and it's perfectly fine. No infections were found when I scanned as well.

It's starting to become frustrating and I can't even do anything on my PC because it's acting up. Any and all help is more than appreciated and welcome. Thank you.

Hi, I have a weird problem, I have 3 systems on my device: windows(10), ubuntu and Arch lately when i was configuring Firefox on fresh arch install I was annoyed that I needed to re-login to every single s...t again. So I thought "Why can I just share the same FF profile between systems" Long story short it didn't work on Arch. I was forced to compile FF from source and now it works... but when I'm logged in on Ubuntu and trying to launch FF from GNU I always see this error. it's working when i point out to profile from the command line with "-p <dir>". but even then when I go to about:profiles and click "launch in new browser" it's still pooping with this error. So Am I doing something wrong or it is just impossible to do this seamlessly? is there a better(correct?) way to achieve the same functionality?

thanks for reading, ill humbly take any advice.

EDIT: I have copied the profile's folder to a separate partition which is auto mounted tried it on Ubuntu (at this time it had been working just fine) and after using it on Arch when I was back on Ubuntu it was displaying this error

I really like Firefox, and have been using it for many years. I even used Netscape navigator back in the bad old days! But there are two things that really annoy me:

- I can't seem to be able to place bookmarks into folders on the desktop (like I can with Vivaldi). For example: I visit a lot of news sites, so I'd like to have a folder called "News", and put them all it there instead of having my news site bookmarks all over the desktop. I just find it a cleaner way to organise my desktop.

- I can't seem to customize my search, apart from selecting between the default search engines. I'd like to be able to search "google.co.za" instead of "google.com", but there doesn't seem to be a way of changing that (again, like I can with Vivaldi).

If I could sort these issues out, Firefox would be my main browser, and I'd scrap Vivaldi as I find that it's getting too "heavy". (Of course, maybe these features contribute to that!)

Thank you.

I've looked for solutions, some had weird MTU settings, some needed to enable hardware acceleration in Chrome, but haven't found a solution that works. Created a new profile to try that out, but still no dice.

I can do a test recording in Google Meet, which displays my video just fine, but when playing back, it's just a black screen, and that is also what happens if I share my screen. Participants get a lot of black.

I've been using Firefox with Google meet for many years, and never had this problem before. I did report the issue in Meet, but it's not likely to attract much attention from Google.

Suggestions much appreciated.

Yesterday morning I opened my RBS online banking, without any problem. Late yesterday evening I tried repeatedly to open my RBS online banking without success. I would go through the usual log in process and end up with a blank screen. I tried a Firefox refresh which made no difference.

I'm using Manjaro Linux and I place Firefox in a particular position on the screen. In the previous version, just before 122.0, Firefox would "remember" the last position on the screen. Now when it starts up, the window is in the middle of the screen and not to the top left as when it was shut down. Anyone else notice this?

Hi I have tried to install firefox updates, but my software tells me that i have not managed to do it since 2021, when I thought I had. I have an old Sony Viao running Open SUSE 15.1. Would you kindly assist me

Kind regards Noel Bonczoszek

I want to see the stats for the video currently playing (resolution, frame rate, etc...)

i've confirmed this setting media.video_stats.enabled is true.

i right click on a video but no option to see stats.

does this exist? i've looked for an extension too but cant find any.

I want to remove the top toolbar. I actually use the plug-in called “New windows without toolbar” for this, but I have to activate this plug-in by clicking on it every time. I want the toolbar to not appear at all when Firefox first opens, how can I achieve this?

Sorry for English..

I have a fresh Ubuntu 22.04 workstation running on a Xeon w5-3433 (16x 2.0-4.2GHz). I noticed that certain front-end heavy websites (e.g. chess.com) are extremely laggy & cause CPU usage to spike to the point that other processes (e.g. Spotify audio processing) hang for ~500 ms. Additionally, simple actions (opening a new tab, closing the ctrl-f search bar) also cause CPU spikes & hangs. This shouldn't be happening.

Thus far I have: 1) Switched snap channel to Firefox beta 2) Switched snap channel to Firefox nightly 3) Uninstalled the Firefox snap; reinstalled from the new Mozilla repo via apt 4) Cried, sobbed 5) Obtained turbostat info (interrupts spike from ~75k to >100k when actively using ff (e.g. mousing over website elements/having chess.com tab active/rendering); ff is open always). Here it is: https://pastebin.com/Q2ZCDC0t 6) Run the ff profiler on laggy tabs. Screenshot attached.

Help! I am perplexed. What's all this RefreshDriver stuff? How do I kill the jank?

Why is mousewheel.with_control.action = 5 not the default in 2024 ? or at least an accessibility features ? I have multiple over the years had to help my older parents with `broken` website due to the actual default increasing the font size instead of behaving as a pinch and zoom

I am using a two finger scrolling on a touchpad to scroll vertically in Firefox. How can i change the scrolling in Firefox to be like vscode or konsole. I want the scrolling to not have a delay and be instant.

I recently updated Firefox and now I'm getting a noticeable stutter when playing back videos. I used to have this issue when I first got my steam deck so I installed a flatpak ffmpeg-full which fixed the issue completely but a recent update I installed has brought the issue back. I uninstalled and reinstalled the flatpak and restarted my device but the issue persists.

The twitter videos are not getting played in Firefox, details are below:

Version: 122.0 (64-bit) OS: Fedora 39

Below is the error message : [Child 308118, MediaDecoderStateMachine #2] WARNING: Decoder=7fdadbc58400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-122.0/dom/media/MediaDecoderStateMachineBase.cpp:166

Thanks!

I am running Firefox 122.0 on Ubuntu 22.04. When I have a decent number of tabs open, firefox will often randomly decide to lock up completely. GUI is almost entirely unresponsive. I can right click the menu bar area and get the Menu Bar/Bookmark Options/etc. context menu, but it's also screwed up (2 options that are normally there are completely missing). This has occurred for a year or so. Originally, I used the snap version but recently backed up and switched to installing from .deb. Still the same issue. I saw recommendations for turning off hardware acceleration, and that didn't prevent the problem. Running `top`, I see that I always have plenty of memory (at least 10G free) free and worst case 1 thread is being run 100% but the others are hardly being utilized. No crash reports are generated (I will pkill firefox to stop it). Addons and extensions are all disabled.

I recently realized that hitting the windows key with firefox frozen will allow the web page to show again, but it's back to frozen. I keep hitting the windows key, and it will unfreeze just momentarily to show me the current webpage that is up. I can also Ctrl+N and open a new window, and the new window works perfectly fine independent of the completely frozen first window.
