Firefox Support Forum

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.

I have a laptop with Ubuntu 22.04. Firefox 307 from deb package works perfect. I wanted to give a try to Flatpak variant 306, which works well too, except two finger gestures back and front won't work. Scroll works. Any scheduled fix for that? Would be cool to move to flatpack completely.

Rendering is completely broken after the upgrade to Ubuntu 22.04 LTS. See attached image. This particular render is of the advanced preferences page, or actually the prompt warning that it could break something is somewhere in there. The mountains are my desktop, it's all alpha channel in Firefox. Nothing else seems broken, and other apps and games, both using GPU acceleration and not, are working fine.

I have removed and reinstalled firefox (snap remove firefox then snap install firefox) but did not delete all of the history files in between. (I am posting this from a different browser, since Firefox is unusable.)

Ubuntu 22.04.1 LTS, Firefox 105.0.3 (64-bit)

I'm using Firefox 106.0.1 on Ubuntu 22.10 from Mozilla's official PPA but when I open some websites the browser crashes with the message "Exiting due to channel error.". I found the error could be related to libwebp with LTO enabled, may be it is, but I rebuilt the Ubuntu's package without LTO and one website stopped crashing, dell.com support page, but several others still crash, like amd.com.

Using either the SNAP or .deb versions of Firefox on Ubuntu 22.04 I am running into issues attaching files on remote systems. I can browse to mounted network drives and select files but when clicking open nothing is attached in any of my online email accounts. This also applies to the open dialog box. I have tried using the KDE File Picker as well as the GTK one but they both fail. This is not an issue for LibreOffice or other programs and greatly impacts the usefulness of Firefox.

I am using a Dell Inspiron 3847 with the standard keyboard which came the system years ago

Recently, when viewing a large online page, when I try to scroll down, the scroll doesn't start until about two seconds after I press my scroll key (which is the lower-middle key of the 4 keys between my right-hand "Ctrl" key and the "0" of the 10-key keyboard at the far right of the keyboard).

This delay started happening a few weeks ago. I do not know whether something I did caused it.

How can I scroll my view starting immediately, rather than having to wait two seconds for it to start?

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

The tool tip colour for the Downloads is white text over a yellow background - it's practically impossible to read. Perhaps this is an error with the release, but if not, can this extreme lack of textual contrast be changed? I need dark / black text on light backgrounds.

Firefox crashes (tested in troubleshoot mode) for this URL : Link which causes crash https://developers.google.com/android/guides/opensource#java

There are no crash logs generated either (checked in about:crashes) . Attaching a post-crash dialog screenshot

If I try to attach or download (only with the Always ask you where to save files option turned on) a file in any website, the browser doesn't open the Files window. Drag and drop works. I am able to choose the download folder from the settings and upload any folder, though.

I'm running Firefox 103.0.1 on Linux Ubuntu 22.04 LTS.

Good evening, I've some problem with firefox sometime it don't start (if I restart Ububtu 22 kernel 6.0.0 in use firefox start) and some times when I try to save an image it crash an close. Here below you can find the crash code error. Thanks a lot for the support

Firefox 102.0 (65 bit) on Ubuntu 20.04, for some reason has begun downloading mp3 files as mpga files (Google Chrome doesn't do this). This forces me to edit the extension as I download, since my mp3 player doesn't recognize the mpga extension. How can I fix this?

I updated Firefox and an old version remains on the "show applications" screen. I suspected it might be another profile, so I went to about:profiles and removed it, but it's still there. As I am relatively new to Linux (Ubuntu specifically), I would appreciate some help with this issue.

Zorin16-Linux version 99.0 Ubuntu Canonical 1.0, -found in Help/About. Firefox recognition of version below says 91.0. Also have Linux Mint 19.3 (Tricia). Computer 15YO Dell Dimension 900.

I've had no problems with Linux Firefox for many years. I do not use any other Non-Linux OSes. Linux Mint updates Firefox regularly and so do I in that OS. I'm currently in a free version of Zorin which doesn't seem to push out updates, so my Zorin Firefox may be sadly out of date.

At any rate, today in Zorin, when I went to several of the bigger online sales platforms, they refused to accept my Firefox and suggested Chrome, Opera, and Safari; Target suggested Firefox.

Went to Mozilla to try and upgrade, but it didn't offer the Linux browser automatically when it read my computer. I was only offered the Windows browser. This may be because the computer is an old Dell Windows machine that I converted to Linux or it may not. I've never had this happen before.

Yesterday in Linux Mint, in which Firefox is upgraded at least weekly, the same thing happened once with a big online retailer. They said my browser was outdated and unsafe.

What's going on? I'm wondering if Linux OSes are simply not being accepted when the big retailers are doing software upgrades, or is something going on with Firefox?

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.
