Firefox Community Forum

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

Firefox won't start after updating to version 123.0 on Ubuntu OS.

At the same time, no errors will appear, and there is also no specific crash report that would help understand the reason.

How to restore the previous version without losing profile data?

For the past few months, the browser will no longer download any files. The only diagnostic that I can see is failed when the download is attempted. I have refreshed firefox and the problem remains. Chrome can download without any problems, but I used firefox for many years and wish to continue.

Firefox Browser 125.0.3, Flatpak Every few minutes, the mouse locks up on Ubuntu 23.10 and it only happens with I have Firefox open. I have have no extension, and history is turned off I have lived with this for months on multiple updates hoping for someone working on Firefox would figure out the issue and fix it.

This issue never happens to me on my windows PCs.

Any solutions? thanks Richard

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 changed a global setting in the KDE Breeze theme to always show scrollbar arrows. It works in most windows but not in Firefox, which refuses to display them. Is there a way to fix this? It is a major accessibility problem.

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

I am running Lubuntu 22.04LTS (have been for months now), with Firefox 130.0.1 installed via the normal vanilla apt.

It was working fine until a few days ago (perhaps after an update, but I can't recall specifically), and then just stopped being able to save anything.

For example, right clicking on an image will bring up "Save As..." as an option, but when I choose that, nothing happens. No prompt to save, nor does the file appear anywhere.

When I choose "Save" as a pulldown on cloud XLSX files...similarly, nothing happens.

When I download something, Firefox is supposed to open up a prompt asking me where I want to save the file but that never opens...nor does the file download.

I am totally baffled.

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

Hey guys, I'm using Ubuntu 24.04 with Firefox 124.0 .deb release from this repository: https://launchpad.net/%7Emozillateam/+archive/ubuntu/ppa I enabled "Ask whether to open or save files" from settings. Whenever the Open/Save dialogue is shown and I choose Open, I expect that the file would be opened using the default application. But Firefox asks again to choose the application by which the file (file link?) should be opened. It seems that Firefox is somehow change the way the files are opened through external applications and transformed local file addresses to file://uri/on/disk.

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

• • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

• • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

• • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel
