Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

This is one of the more annoying messages Firefox has recently added:

"Your browser is being managed by your organisation."

It is obviously wrong, because it is shown on a private Ubuntu 24.04 computer where I have myself installed Firefox from a tarball installation (Firefox version 142.0.1).

The about:policies page just shows: Homepage: URL "https://start.ubuntu-mate.org/"

  Locked	false
  StartPage	"homepage"

Why does Firefox give such obviously misleading information? All the other articles are not helpful at all either, some are talking about security software, some about malware.

This is an extremely user-unfriendly and confusing message: if security software is to blame, why does Firefox not tell what exactly is restricted? When malware changed something why does Firefox not tell what it changed? What even does the message actually imply, what is prevented what otherwise would work and why? What does the information shown on the about:policies page really tell me?

This is by the way shown when starting Firefox using an EMPTY directory for its profile (so making it use a brand new profile), running from a brand new installation directory extracted from a tar file. So what on earth makes it think it is "managed by my organization"?

There is no extension installed, no policies.json file in the newly created profile, nothing. It looks as if the firefox browser would just arrive with this weird setting/configuration comiled right into it?

Why cannot see Mozilla browser if I set it as a default browser?

Using Ubuntu: User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:134.0) Gecko/20100101 Firefox/134.0

Firefox in Ubuntu Linux is broken for about 30% of the web; only CHROME works. This problem just keeps getting worse. Please fix; it doesn't matter whether FF is more secure, if it doesn't work - what's the point?

firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

I am experiencing an issue with the Picture-in-Picture (PiP) functionality in Firefox on Ubuntu. Unlike on Windows, where the PiP window automatically appears when switching tabs or pages, this does not happen on my system.

When I manually activate the PiP feature by clicking the button, the window does appear; however, it is placed behind the browser window and remains at the lowest level among other open windows. This causes it to be obscured by other applications and requires me to manually bring it to the front and adjust its position every time.

Is there a way to automate this process or resolve the issue so that the PiP window behaves as expected (i.e., stays on top of other windows and works seamlessly)? Please let me know if there are any settings, extensions, or workarounds that could address this problem.

Thank you in advance for your assistance!

Hello. I am using Linux Mint 21.3 cinnamon and Firefox 144.0.2 When I use Google maps and the yellow small pointer (cartoon) to go on a specific street, the window come black when shifting to street view. My only extension is disabled, hardware acceleration unchecked, cache cleared and cookies cleared. I have made fresh install and nothing help. Troubleshooting mode allow street view to work fine but normal mode don't work. Google chrome work good. Chromium work good. And finally, Firefox work ok on my Linux mint LMDE 6.

Any idea where to go to solve this issue?

Thanks for your support

I'd been trying to download 2 large files from Icann and kept getting premature completion with Firefox. It would be showing ##MB of 356MB downloaded for a few seconds and then out of the blues it just says completed. As you can see in the shared video, I've tried this several times.

I thought that maybe one of the Firefox addons was causing the issue so I tried Troubleshoot Mode but that resulted in the same behavior.

I then went into Firefox Profile Manager and created a new profile. But that too had the same behavior - 🤔!

So I then tried Chromium. It completed the download successfully and the file passed gunzip test.

So, why is Firefox, even with a new profile, failing to complete a download?

I just set up a server with linux Ubuntu 24.04 Desktop, with Firefox 129.0.2 included to do some dev and testing work.

Problem: Firefox seems unable to see or open files that are above or outside the user's home dir tree.

The only extra packages installed are the LAMP stack and Google Chrome, which has no problem. (had to have something for A/B testing.)

I've tried entering the url of file:///var/www/index.html, I've tried selecting 'open with...' from the files app, etc. Nothing works.

I can get to the file through http://localserver/index.html with no issues. I've verified permissions on the entire directory tree to the file. Everything from end to end has read permissions for all, 755.

I've checked the following advanced settings: security.sandbox.content.level..............................0 (started at 4, now at 0, no effect or change.) security.fileuri.strict_origin_policy.........................false (default setting as installed.)

I am able to open file:/// and get a dir listing. BUT, if I click on var, it gives "Access to the file was denied." I even tried changing the permissions on /var to 777, but no change.

This seems to be a Firefox only problem, since Google Chrome works where firefox doesn't.

I've spent several hours searching for ways to fix this, all with no success. Does anyone have any idea how to fix this, or even what to look at???

Browsing works well on my Ubuntu/Linux 22.04.5 laptop except one site. Images are not loading. I can see it has js-errors which might be related. And that may be because some js files are being blocked. The site does work on my iphone though. And using Browserstack I can see it works with other OS.

The site is: knowledgecottonapparel . com

I've verified that others using Linux has the same issue, https://askubuntu.com/questions/1526728/issue-with-specific-site

To preface this, I am not sure if this is caused by my OS (Ubuntu 24.04) or by the way Firefox tends to work on Linux as other issues have been (and therefore, might be resolved with a change in about:config).

Problem: When I download a file and download another one right after that one, the window showing the folder I am choosing to download to won't show the file/image preview of the file I just downloaded before; it only shows the correct preview once I have opened the file manager on my OS; after doing that the file preview is up to date again. (basically, it only shows the correct file preview when I viewed the files on my desktop before opening the download window and will not keep up to date with the most recent changes on its own like it does on Windows for example)

I know that there is a generic Linux iteration that can be downloaded, but it does not appear to allow for use on ARM64. Is there a way that I can download, install, and access Firefox on my Orange Pi 5 Plus?

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.
