Firefox Support Forum

Sometimes, unpredictably, the browser stops working in a way that the page stops working, and trying to reload the page, open a new tab, or even save the content on a page, simply doesn't work. The singlefile extension fails, and I can't just disable it, and re-enable it, the browser won't let me do that, either. The browser's built-in save function won't even progress to completion. That is inconvenient when I'm trying to save chat, or some other ephemeral thing, that won't be available after restarting the browser. I don't want this to happen anymore. I don't want this situation to recur. I'm not sure what to do to prevent it in the future. I'm not sure what causes this mess. I don't know what else to say about it. Please tell me what I'm doing wrong, and how to fix this?

The browser seemed to be in the throes a crash, but it just wouldn't finish itself off. So I killed the main process, which I thought should trigger a crash report, but it didn't.

I use -url argument for launching Firefox with two tabs.

How can I specify the container for each tab?

Ex. firefox -url "https://web.whatsapp.com/"-url "https://web.whatsapp.com/" The first tab belongs to 1st Whatsapp account While the 2nd belongs for another one

- I use Multi-Account Containers - Firefox 108.0.1 (64-bit) - Linux Mint 21.1 Xfce

Hello, i am using Firefox in Ubuntu( installed by default) in Vbox. Today, i opened a .pdf link and tried to download it, once i pressed the button the Firefox closed( or crashed). Then i opened my gmail and wanted to send an image in letter, i pressed the button to add a file and Firefox closed again. After that i typed sudo apt-get update and upgrade in terminal, now waiting to see if there is any changes. I opened about:crashes and submitted report. Any help is welcomed, thank you. bp-05bdb602-5c39-493a-906a-22f8c0230103 03.01.2023, 13:59 bp-f7ab49f3-c17e-437d-936f-4dec60230103 03.01.2023, 13:59 bp-045d3e28-eab5-4cc3-9f24-cbda40230103 03.01.2023, 13:59 bp-e3d56256-3f44-4477-b66e-9dda10230103 03.01.2023, 13:59 bp-387b5231-2c52-4827-ad86-a5a550230103 03.01.2023, 13:59

build command just compiles everything. install command installs Firefox on local machine (for all users). package command creates an isolated all-in-one archive from which Firefox can be run (including all libraries, at least that what I think it is). I don't know what artifact command does, but I think it's not it. Is there any command that can produce .deb file (which can be easily installed in one command)? My only hope right now is to copy whatever mach install is doing (all necessary folders etc.) and bundle everything in a custom archive. The main problem is the ginormous size of 32 GiB after build is complete. (I can't archive that and use as a portable installer/builder, which indeed would be very convenient but the size…)

I updated to Firefox 109 on my CentOS 9 Stream system. I noted that streaming video did not work. I tested with Disney+ and the CW TV network. I changed a few settings, and I have a subscription to Disney+ but CWTV is free for all to connect to (well, at least in the US, I can't guarantee overseas access). So, what is the problem? Well, it is two-fold. On Disney+, I get video and closed captioning but just a low steady beeping tone instead of audio. On CWTV, I get nothing but a green screen and that same tone. It is not an issue with the codecs or the OS, because Google Chrome 109.0.5414.74 displays them perfectly fine. I should note that before I started tweaking settings, I kept getting the FFMPEG errors that plague most people. See the settings below in the shared data.

At some point last year, every website started asking me to allow cookies on every visit. I couldn't see how to make Firefox more easy-going back then but now I've decided I don't need the protection since I'm using uBlock and NoScript anyway.

I have gone through the support forum answers to other people and I have all my settings configured to allow cookies and not delete them on FF restarts, custom blocking with no checkboxes checked, but still I see these cookie permissions questions all the time. What can I do?

During the past two weeks, I added annotations to three PDF files using Firefox, saving the file each time I added an annotation. After Firefox updated to v109.0 on a Win10 computer, I discovered that the annotations were gone in the first 2 PDFs. Does anyone have any insights into what happened and how to recover the annotations? I did try copying the PDFs to a computer that was running Firefox v108.0.2, but the annotations were still not visible.

I change the default action for e.g. mime type PDF to a bash script. - works I get the filename of the downloaded pdf file in my bash script - works I can do things with this downloaded file - works

But can I get the download URL of this file in my script? It's not a dedicated URL in a tab - so I can not read the URL of the active tab.

It's a direct download link from, let' say, google search.

What do I have to do to get the URL of the downloaded file in a bash script?

Thank you in advanced!

I have an account on hidive.com and can not longer login with Firefox 109. Firefox 108 still works. I have tried 109 on both linux and Windows 10. I tried refreshing Firefox and disabled all addons. The page after clicking sign-in with my credentials just is a blank page and the source for said page is blank.

After downloading about 10 GiB of source code and then building another 15 GiB, to install Firefox you need to use `./mach install` or more correctly: alias install='sudo sh -c "export MOZBUILD_STATE_PATH=$HOME/.mozbuild; ./mach install"'

But to re-install Nightly Firefox on the freshly installed (even the same) OS I will have to either save 25 GiB of source+build (+.mozbuild and other stuff) or to redo everything from scratch (needs at least 1h 20m). I'm having a hard time understanding all the abstractions and redirections from `./mach install` (and Makefile from ./obj-*/ which is automatically generated) to reconstruct a minimal set of things to install Firefox.

I need a bundle of files+dirs which is enough to install everything system-wide for Firefox to work properly. Maybe even simply run `./mach install` in this "minimal build installation" (if possible).

P.S. I'm using Debian based distro(s).

Hi beloved community!

I've been experiencing problems with firefox on Ubuntu. Some (if not all) windows randomly bug out and I can instantly tell because:

1. Hover animations stop working completely, in-page and browser ones too (menu, tabs, etc) 2. Animations work if I scroll or click over any element 3. Browser window becomes unmovable, I can't drag the window, only by doing alt+space and selecting move 4. Top bar (URL, tabs, config buttons, minimize, restore, close buttons too) doesn't resize if I get out of full-screen

If I move tabs to a new window they work perfectly, until they don't anymore. It can be almost instantly or it may work perfectly for hours

At first I could ignore it but now it's just getting so annoying it's practically unusable

My primary desktop is mate/compiz on Fedora 36. I typically have 6 Workspaces available, 4 dedicated to specific apps (eg. Firefox runs in WS#2, several terminal sessions in WS#1).

In a terminal window, when I right-click a web URL I get an action menu including an entry "Open Link". Recently the behavior resulting when I select that menu item has changed.

Prior, Desired Behavior: My current workspace switches to that containing Firefox, Firefox receives focus and the URL is opened in a new tab.

New, Undesired Behavior: Firefox is moved from its workspace to my current workspace and the URL is opened in a new tab. I must return Firefox to its "assigned" workspace.

Experimenting suggests the behavior change is due to something in the profile used by Firefox though I'm unable to identify it.

Other browsers (brave, chrome, firefox from mozilla.org rather than from the fedora package repo) do not exhibit the new behavior. Firefox on other systems (some Fedora/mate/compiz, others varying) do not exhibit the new behavior.

Firefox (from Fedora repos) with all addons (only 7) disabled continues to exhibit the new behavior.

A new Firefox update today (to 109.0) continues to exhibit the new, undesired behavior.

As noted above, Firefox from mozilla.org, does not exhibit the new, undesired behavior. But that is with a new profile. If it is started with the profile of the Fedora Firefox, it DOES exhibit the undesired behavior.

Can someone suggest a setting or profile change to restore the old, desired behavior?

Tnx, Jon

Hello!

Whenever I join a conference/meeting, web version of Teams asks for camera and microphone in one window, e. g. "Allow camera and microphone? yes/no". I can, of course, press No, then press "Yes, continue without audio" in Teams, and then allow microphone, but that's really annoying.

Is it possible for firefox to ask it in two separate dialog window? 1. Do you want to grant Teams access to microphone? - yes 2. Do you want to grant Teams access to camera? - no

I'm trying to identify why the GPU RAM is reported as 0 in the report when an expected value should be greater than 0. If the browser is actually treating the GPU as having zero RAM it might be a starting point to investigate why the browser is unresponsive for sometimes up to 30 second when 42 tabs are open and I'm opening a new tab and trying to interact with an existing tab after switching between tabs or windows. Often these are divided between two or three windows grouping tabs as part of a multi monitor workflow while editing Wiki content. The system responsiveness is unaffected and other program do not change in their responsiveness. This occurs while CPU is under load and not under load, but occurs more frequently when under cpu load (low priority compute applications via BOINC for distributed computing). No GPU compute is being used.

Firefox was installed via the Pop!_OS Pop!_Shop. Confusingly the Pop!_Shop lists two Firefox Browsers (one by Mozilla, and one by the Mozilla Corporation) I'm told that these are separate due to their app IDs not matching which prevents the listings from being merged, but it is unclear which is sourced from what repository and how they differ for install as flatpak, deb, etc are not specified in the UI of the Pop!_Shop.

Hi,

I have just upgraded to the newest version of Firefox in the Ubuntu 22.04 LTS Repository. I'm running LXLE Linux, a Debian derivative.

I ran

sudo apt-get update

to update my sources, and then ran

sudo apt-get upgrade

to execute the system upgrade.

After I upgraded, I started Firefox, and all my history over 6 months, my passwords, and my profile settings were obliterated to a stock Firefox install.

How do I access my old information? I have lost passwords. I cannot access business information or email. I have tried searching for profiles using about:profiles, but I have only one - the default. I have also searched in the .mozilla/firefox folder in my home directory, and I find profiles.ini in that folder. However, there are only two profiles, and I tried setting Default=1 for each of them and then starting Firefox, but with no different result. The new installation of Firefox launches.

In my /home/deadpool/snap folder, I have firefox, and multiple versions, or so it seems. I have this:

deadpool@deadpool-pc:~/snap/firefox$ ls 2263 2277 common current deadpool@deadpool-pc:~/snap/firefox$ ls -lah total 20K drwxr-xr-x 5 deadpool deadpool 4.0K Jan 31 12:29 . drwx------ 10 deadpool deadpool 4.0K Jul 31 2022 .. drwxr-xr-x 4 deadpool deadpool 4.0K Jan 10 2020 2263 drwxr-xr-x 4 deadpool deadpool 4.0K Jan 31 12:29 2277 drwxr-xr-x 4 deadpool deadpool 4.0K Jan 10 2020 common lrwxrwxrwx 1 deadpool deadpool 4 Jan 31 12:29 current -> 2277 deadpool@deadpool-pc:~/snap/firefox$

It looks like there is a symlink for current to the 2077. I would hypothesize that if I set the symlink to 2263, I would see my old firefox install. Is that correct? I don't want to break my install or lose data. I'm sick of that shit.

Thanks, Nathan

I'm currently building/testing a website with Firefox and Selenium, which requires interacting with the camera/microphone.

To avoid having real hardware present, I've configured media.naviagator.streams.fake=true, however for some time now, this isn't enough anymore (not exactly sure for how long).

When running normally (i.e. not headless), I can see that the permission prompt ("Allow website to use your camera/microphone?"), but I can't interact with it from Selenium.

Is there a way to disable this prompt programmatically?
