Firefox Support Forum

I use Mozilla as my browser on Windows 7. When I click on Mozilla I get an Error page which reads, " Server Error in "/" Application. Runtime Error. Not sure how to fix this. Can you help. Thank-you

UbuntuStudio 22.04 uses the Firefox Snap package by default. The latest automatic update does not display pages correctly in normal mode, but does work correctly on Safe Mode. Snap.io lists only the latest version of Firefox so I was unable to ask snap to revert to the previous release (prior to 5 Mar 24) and by the time I had tried to investigate the previous version was no longer cached. I did not see a way to force a fresh download of firefox from the latest channel on snap.io.

I tried the snap beta channel for v124, but that exhibited the same problems.

I tried adding a symbolic link to colors.css after seeing firefox complaining that it could not be found when started from the command line. That removed the error/warning message but did not clear the problem with normal mode.

I use the en-GB locale extension only. The technical details about my PC are as follows:

• Operating System: Ubuntu Studio 22.04
• KDE Plasma Version: 5.24.7
• KDE Frameworks Version: 5.92.0
• Qt Version: 5.15.3
• Kernel Version: 6.5.0-25-lowlatency (64-bit)
• Graphics Platform: X11
• Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
• Memory: 30.5 GiB of RAM
• Graphics Processor: RAPHAEL_MENDOCINO

I have now downloaded v123 and installed it in my local home directory, and that version is working well. I have removed the firefox channel via snap. It is likely to be a fault in the construction of the snap for v123 that was not present for v122 prior to 5 Mar 24.

I am getting tired of being told replace this file with this

does it read firefox expert or intermediate on my account? no it does not it reads a person with no knowleage or skills in this field

and you are basically expecting them to figure this out on their own by giving the smallest shread of help by saying "replace the loginsjson with the logins-backupjson"

Yet i have no idea on how to do that.

so you basically caused a blind student who has no idea what there doing

because the F...ing instructors arent giving descriptive detail instruction on how to perform the task

and its actually sad i have to even do this

so for the last time please will someone give detail instruction on how to replace the loginsjson in the profile folder with the logins-backupjson that is on my desktop screen

and its not like i can just search this because iv tried and what do you know its given as much help as you have

Hello,

I am experiencing a persistent issue with web browsers on my Lenovo Legion T5 26IAB running Windows 11 Home. Regardless of whether I use Mozilla Firefox, the browser frequently crashes. This happens at least once a day, and it seems to be unrelated to the number of tabs open or the specific content being viewed. I did the help -> diagnose mode without plugin and it crashed too, im not sure what this is realted to.

The crashes often present with an error message suggesting a failure in the new tabs or trying to load a old one, despite the fact that my system's RAM usage is typically around 60-70%. I have already updated the BIOS, Lenovo drivers, and NVIDIA graphics drivers, but the issue persists.

I'm seeking advice on what might be causing these browser crashes. Is it possible that there's a compatibility issue with Windows 11 Home? Could it be related to the graphics card or its drivers, even though they are up-to-date? I have not changed the power cable from my old PC; could this be a factor?

Any insights, suggestions, or similar experiences would be greatly appreciated. I'm trying to determine if this is a hardware issue, a driver conflict, or something else entirely.

Thank you in advance for your help.

Whenever I start Firefox it loads up on the upper left corner in a minimized version and I have to double click the maximizing button to get everything right. I tried the tip of deleting the .js file in the Profile folder of the browser. I did that 5 times and the problem still occurs. Everything is up to date. What's wrong?

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.

since the update today my browser's been really slow to stream video across the board.

i fixed this a few months ago by turning hardware acceleration off and i tried to check if it had been turned back on and the entire option is completely gone from the performance section in settings.

i dont see an option anywhere else to change this, and i really dont want to switch back to chrome for streaming. is there a hidden option somewhere that im missing?

Dear friends at mozilla.org,

Thank you for your excellent browser, which I've used almost from its first versions.

I'd like to compile its source code, which I've downloaded from your website, into a working browser. I've spent several days, and get only as far as not-terribly-helpful error messages, that indicate strongly that I'm using versions of tools and libraries that the source code doesn't like.

I'm using

 linux kernel 6.1.0-13-686-pae (from Debian)
 gcc 13.2.0-9
 perl 5.36.0
 python 3.11.7

It's sufficiently important for me to compile firefox that I'd install a fresh linux system for this purpose. Could you possibly recommend to me what linux distribution I could install, and versions of compilation tools, header files, libraries, etc. that are known to work for compiling firefox? I'd be glad to report back to you my results, to help others who'd like to compile firefox.

In case you're wondering, I'm perfectly competent in installing software, including compiling anything. I'm an M.I.T. graduate, and have been a professional computer programmer for most of the half-century of my working life.

Thank you kindly for any response that you have time to send to me.

Very truly yours,

Around August of last year I started getting this issue where I am unable to reach any Google related site like Youtube, Gmail and such. It drove me crazy and at some point I started using other browsers because of this issue. Sometimes my request goes through and sometimes its blocked. I have disabled my anti-virus, stopped all plugins, but all my attempts at fixing this were in vain.

Characters dissapearing, missing, garbled only in Firefox. Seems to be ok in troubleshooting mode. This only happens in Firefox so it appears to be isolated. As you hover over links is when it happens the most. I have the latest version installed and was just loaded on a new system.

i use firefox on ubuntu and a dropdown terminal app called tilda. i configured the F1 key in the system to bring down the tilda terminal. it works in every other application, just when firefox is in front, the F1 key does nothing. it wasn't the case before, now it is.

I keep getting a message that says on YouTube "experiencing interruptions, find out why?'. The videos pause and are choppy. When I click find out why, it's telling me to turn off my high resolution. I don't even know how to do this. My tower is connected to a samsung hd smart tv, that serves as my monitor. I have a wireless keyboard and mouse. The message is constant - all day long, every day. Can you please help me fix this problem. I am a paying member of YouTube Premium. Thank you.

Blank Page when clicking on tracking link from UPS website, https://www.ups.com/track?loc=en_US How do I fix this ? Thanks

I am having issues with Firefox crashing at various times though out the day. It always starts out fine, but at some point it just stops responding and I have to close the browser and reopen it. This happens at least once a day and it does it on different units (my LG Laptop, Dell Desktops (2 different units-1 at work and 1 at home), Surface Pro 9, my Dell laptop), so I know it is not the unit, it is something in Firefox! My Dell laptop runs Windows 10, all the others run Windows 11. Please look into this and provide a patch. Thank you!

My Dell Laptop INSPIRON 3793 running the Firefox/Mozilla Browser when I stream in Youtube or LiveNews periodically goes into the images in the photos I uploaded here. I am compelled to do a hard restart. I have been working with Dell Technical Services and they indicate they have no history of this issue. I am running Windows 10. My system has all technical updates including current drivers . I really do NOT want to move off FireFox but I getting pressure to run another Browser and wait and see if the problem surfaces. Is there any history of this issue with this Firefox. Any help or insight you can provide would be greatly appreciated. Thank you, Cate Brown
