Firefox Support ƒe Forum

When I open firefox in ubuntu linux. (WSLg) Fresh install. I can't go to settings in firefox. Steps: press the hamburger menu, press settings, nothing happens.

OS: Ubuntu 22.04.4 LTS on Windows 10 x86_64 Kernel: 5.15.146.1-microsoft-standard-WSL2 Shell: bash 5.1.16

I am no longer able to add attachments to gmail or upload images or attachments to websites. When I click on the attachment icon or upload button, my finder window does not open. However, it works in other browsers. How can I fix this?

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

So I'll be typing like normal (I type 100 WPM), and all of a sudden, I'll type a sentence, but each individual letter starts taking about 3 seconds to show up on the screen. I have to sit and wait a super long time for everything I typed to finally show up. Other times, I move my mouse over something I should be able to click on, and have to wait a long time for the arrow to turn into a hand, letting me click on it. These periods of slowness will last a few minutes, then disappear.

What's really interesting is that when the slowness starts, I can type just fine up in the URL bar. I might type my entire message there, then copy paste it down to where ever I was wanting to post it. However, when I do that, if I have another tab open and that tab is playing music, the music will start to break up and lag as I type. Again, after a while, the slowness disappears and we're back to normal.

Can anyone tell me what's going on?

I'm unable to load any web pages since receiving an update 4-17-24 on Windows 11. It doesn't seem likely I'll be able to get another update to fix this via the browser. What do I do? Uninstall?

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

I have been using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that the update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and Firefox behaves, until I stop it and restart again. Then I get the same message. I looked online - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis Email hidden for privacy reasons

WIndows 11 64, AMD processor, 64 GB ram. Connected via ethernet and fiber. NordVPN, and Bitdefender (neither of which has produced any error messages).

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

today 4/18/2024 firefox update. Now browser is slow. Task manager showing currently 15 firefox open, even though only one new tab is selected. It is causing laptop to overheat, fan is running constantly. Nothing else is open.

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.
