Firefox 技術支援討論區

Hi, I'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.

EDIT: the issue was solved by installing the following packages, as shown in this question :

xdg-desktop-portal xdg-desktop-portal-gtk

My OS is Pop! OS. Using 'Tidal' as a web based music streaming service and I play vids on YouTube. Every time a new song or video starts, or when I skip, rewind or do anything like that, it auto resets the volume level output in my sound settings to about 75 to 80 % of the max possible level. So basically, I have to adjust each and every new song by hand, it is infuriating. I block facebooknet in Umatrix and firebaseinstallation googleapis as well as google tag manager but nothing else. That's on Tidal, similarly I do not block essential cookies on YouTube, so I don't think that is the problem. I have a hunch that the answer is somewhere in about:config. If this is intentional, then I'm giving up hope. Thank you.

I can't get Firefox to use some custom cursors. Firefox is only recognizing the cursors that came installed with Ubuntu. Any of the cursors I installed will default to DMZ-White, but Firefox is using those cursors that came installed with Ubuntu. I tried defining the default cursor in /usr/share/icons/default/index.theme but did nothing as well. Also I tried with the cursor in /usr/share/icons and in /home/name/.icons and firefox cannot get in any of those.

I don't know if it's something wrong with my cursors or it's some inner thing with Firefox, any one has a guess? Incompatibility or something missing from the cursor?

Any Safe ...As.. in my Firefox isn't working. Nor from right mouse click, nor from menu-file. Currently I'm with 108 under XFCE(Ubuntu). But the troubles was may be after 98. I've disabled all extensions - persist. I tried also Troubleshooting mode - still persist. I've tried reinstalling - persist. Where have to look? With Chromium I do not have such troubles. Thank you!

Brand new installation of Ubuntu Focal (on an ARM Chromebook, using Crouton). Installed Firefox (104), runs fine but as soon as I sign into my Firefox account it immediately crashes. Continues to crash if I start in safe-mode, so I don't think the problem is an extension. After some online research and some trial and error I seem to have determined that I can sign into my Firefox account as long as password sync is disabled. But as soon as I enable password sync, Firefox immediately crashes.

Error message in terminal is always about GPU, which maybe isn't properly set up or maybe Firefox has a problem with it, but if I use the software renderer it doesn't cause a problem (MOZ_ENABLE_WAYLAND=0 firefox). Hard to imagine that this has anything to do with crashing when syncing passwords?

Hi!

I have encountered this really annoying problem on my Firefox app. I give details below. I installed Mozilla Firefox on my freshly installed Ubuntu 22.04.1 LTS. I tried installing it from Snap Store. However, when I tried saving an image from the web (or, truthfully, any other file chosen by the "Save As..." selection), nothing happened, again and again. I tried many things, including following relevant guides from the internet, but nothing changed. The Firefox version is the 107.0.1 (64-bit), a Mozilla Firefox Snap for Ubuntu canonical-002- 1.0. I, also, have to report some other things, as well. When tried installing the browser from the internet (I downloaded a compressed file, containing the executable), the same function seemed to work. I, now, use the executable to access Firefox. However, firstly, because other difficulties (not problems, but difficulties) arise and, secondly, because I'd really like ti use, mostly, snaps, I report this bug here requesting for help, as well.

Any helpful answer will be appreciated!

Thank you!

Whenever a website prompts for me to upload or download a file and I except Firefox crashes, quitting in its entirety. This still occurs in "Troubleshoot" mode so I assume it is not any of my extensions. Here is a crash report from when this occurred if it helps. Another odd observation I made is that I am able to upload a file if I use a "drag-and-drop" feature on a website.

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

These websites won't play audio or video in Firefox 110.0.1, they work in Chrome 110.0.5481.177

https://www.vrt.be/vrtnu/livestream/audio/stubru/ When I click the Play button I get an error "Oops, something went wrong, error code 200" which seems to be a general error code. In Chrome the music starts playing instantly.

https://f1tv.formula1.com/ I have a subscription but video won't play. I can press the Play button, sometimes I see a preloader but the screen stays black, no audio or video. In Chrome the content just starts playing, be it live or recorded content.

Steps I took to get audio/video working inb Firefox, but to no avail:

run above websites in private tabs download Firefox again and run it from its folder in Downloads start Firefox in Troubelshoot mode start Firefox in Troubleshoot mode and Refresh Firefox disabled / enabled Plugin Widevine Content Decryption Module provided by Google Inc disabled / enabled Play DRM-controlled content in Settings disabled / enabled Enhanced Tracking protection disablde / enabled allow media autoplay

In other discussions it was opted to remove the PulseAudio config by running the below command and rebooting rm ~/.config/pulse/*

Any help to get this working again would be greatly appreciated!

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

Hi,

I am running Firefox 108.0 on Ubuntu 20.04.5 and videos on Reddit don't play, they just buffer (?). Youtube works fine. I've tried the suggestions on this page: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#search but nothing seems to work.

Thanks

I have Firefox 107.0b5 (64-bits) Snap for Ubuntu canonical-002 - 1.0 I use Ubuntu Mainline to update to newer kernels. Never had any problem doing that. I am now on 5.19.15. But when I upgrade to kernel 6 (which is now at 6.0.5) Firefox tabs crash. Reloading doesn't help. Each new tab I open gives the same crash message. I have to restart to get Firefox going again. So I removed kernel 6 and reverted back to kernel 5.19 and have no problems any more. But question, what is the problem between kernel 6 and firefox? Does anybody else experience this problem?

I have no other problems with kernel 6 with other programs or hardware or whatever, only firefox tabs crash...

Hi, I've been struggling with this for months and can't find an easy solution or a good explanation. I'm running Ubuntu 22.04 pretty basic, I don't have many custom repositories enabled or anything, just a few additional packages like slack, Teams or Chrome. Ubuntu switched Firefox to snaps as well, and I can't get internet access with it. The error message is:

--- May 12 12:16:20 nuc kernel: [12948.381392] audit: type=1400 audit(1683886580.562:131): apparmor="DENIED" operation="open" profile="snap.firefox.firefox" name="/etc/fstab" pid=7731 comm="firefox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 May 12 12:15:43 nuc rtkit-daemon[1030]: message repeated 3 times: [ Supervising 10 threads of 4 processes of 1 users.] May 12 12:16:20 nuc dbus-daemon[790]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.175' (uid=1000 pid=7731 comm="/snap/firefox/2645/usr/lib/firefox/firefox " label="snap.firefox.firefox (enforce)") ---

Simply stopping (and aa-teardown) doesn't work at all, Firefox doesn't even start without apparmor running. I'm not an expert with apparmor, but I wanted to set in complain mode instead enforce, but I'm struggling with that, too. I didn't touch the /etc/hosts file, the error message is a little different on another Ubuntu 22.04 computer I use, there it complains about permission denied for the resolve.conf. So I'm asking the community, how do you deal with this? Searching the web gives me all kinds of ideas, but none of them work. Could anyone help me out here?

Thanks!

Home built. PC Ubuntu 22.04.1 LTS

Since we have update our OS from Ubuntu 20.04 LTS to Ubuntu 22.04 LTS (a few days ago) Firefox has only shown a Blank screen at first start up, only the very top line is visible showing "Activities" then "Firefox Web Browser". Nothing will work, the only thing that does is Quit.

Restarting Firefox the second time seems to work Okay.

Please can you advise me?

Firefox unter ubuntu 22 hat keinen Zugriff auf die lokalen Dateien (z.B. /usr/share) Der 'open' auf '/usr' scheitert mit 'read'-Zugriffsrecht.

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?

Mit freundlichen Grüßen

Thomas

Crash report submitted bp-37f84164-6125-4ae1-9e55-8a8200230225. Started happening about once a day over last few days possibly since 110 FF update (Ub kernel was also updated a few days back) Have to do a hard power off & restart

HELLO very small cursor on Firefox windows (on all other windows the cursor size is normal) via snap after upgrading to ubuntu 22.04.1 LTS. how can i change it? Thank you

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!

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.
