Firefox Community Forum

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.

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

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

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

Here are the dpkg/apt logs for update:

The problem is that when I tried opening gmail in my ubuntu, it is stuck at loading page, but other browsers like edge can open it without any problem (on the same system).

I tried every thing I can in the support forum of gmail/mozilla/others, but it's still stuck at loading.

That's all.

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

Hi, after upgrade of ubuntu to 24.04 i got into problems with using Firefox. I it running on x11 with proprietary nvidia driver, no matter of source package (snap or deb from the Firefox repository) and no matter of safe mode the Firefox gets frozen when clicking into any dropdown control in side page, the same happens when trying to open bookmark folder in the bookmarks panel or even the dialog that opens from the star icon in address folder that should add page into the bookmarks. When running on command line, in case of the snap version there are just some warnings of some missing css file, in case of the deb version it does not output anything suspicious. I was even trying to change the UI theme (qt) as well as GTK theme in case it makes any difference, but it did not... Thanks for any help.

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

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?

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.

For the past 2 weeks Firefox has been repeatedly crashing soon after going on to certain sites or trying to apply my 2FA authenticator add-on.

Suddenly there's a screen shudder and a new window opens, inviting me to submit a crash report. See attached image.

I do not believe that this is down to Ubuntu 24.04 upgrade done at end of August.

But it's enough for me to largely go over to Chromium and Firefox Dev Ed.

If Mozilla don't act on this crashing I can see its market being lost fairly fast.

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???

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.

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 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?
