Firefox Support Forum

I came across this article https://brave.com/popular-browsers-first-run/ which says the following

> A granular description of the device was also included in this payload: an Apple Model ID (if any), details about the CPU (e.g. cores, extensions, family, L3 and L2 cache, model number, speed, vendor), graphics card and display settings (e.g. name of graphics card, full on-disk address to drivers, driver dates, vendor, version, whether or not the GPU is active, amount of on-board memory, current state of D2D and DWrite, a granular set of feature flags, connected displays (how many, resolutions, refresh rates), hard drives (e.g. model names, type), operating system (e.g. name, date of install, locale, version, granular windows build number), security software (e.g. names of anti-spyware, antivirus, and firewalls in use), and more. > > One of the more interesting observations about this Telemetry payload is the presence of a key called environment.settings.telemetryEnabled, which was set to false. Presumably this would mean no such telemetry calls would be made, which clearly was not the case.

And was wondering if Firefox can shed more light on why it seems that disabling telemetry apparently does not stop the pingsender process?

Cannot mute any video/audio player on any website in Firefox, also attempting to mute a tab has no effect on audio, which continues to play. For example the audio controls on YouTube do not function. Attempting to lower the volume does not work, nor does attempting to mute the player. I also experience this on Twitter and Twitch as well as any other website I visit to consume video or audio media. This issue is exclusive to Firefox on my system and is not present it Chrome or other Chromium based browsers.

When attempting to add an Ipad to Mozilla vpn I seem to have created a new Firefox account with the same primary email address as my original (all of my profile is unset). When I now login to the account I end up in the new account and cannot access the original. However, when I try and delete the new account the new password is rejected and I suspect it wants the password from the original account - I do not want to test this as I do not want to lose my vpn. I am sure that there is confusion between the new and the old since I cannot set up the new account with the same secondary email address as the old one as it claims a user already has an account with this secondary address.

Any ideas on how I can get rid of the new account, if it is new, or clean it up so that I can restore it to the original ?

Whenever Firefox tries to sync, which is naturally happening on startup, it crashes with no error messages. I ran Firefox in safe mode by entering the command firefox -safe-mode and the same thing as before happened, but before it crashed, Firefox wrote Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Segmentation fault in the console, and then exited to the command prompt. Help!?

Hi, I recently had to upgrade my Linux system and Firefox along with it. I am trying to find my bookmark properties or description or comment field with important information that is not kept anywhere else. I found a couple old questions that I thought might be related to this but again they are old:

https://support.mozilla.org/en-US/questions/1233031 https://support.mozilla.org/en-US/questions/1232448

So this is a new question as the others were locked. I tried doing what was listed in them to make a backup/export but looking at the html only shows the book mark and no other fields related to the them. The bookmark-notes add-on is 4 years old so I don't know if that would help me get my stored information. This is causing me lots of problems. Please advise.

Firefox will only open in Safe mode, previously it was working but now it's not.

I have Ubuntu 22.04 Firefox version 99.0.1 (64-bit)

When I try to open it in command line, it's also only opening in safe mode but I do also get some error messages that I've included below.

So what does all this stuff below from the command line actually mean? And how do I fix it?

 (Note to programmers: normally, X errors are reported asynchronously;
  that is, you will receive the error a while after causing it.
  To debug your program, run it with the GDK_SYNCHRONIZE environment

  backtrace from your debugger if you break on the gdk_x_error() function.)

Hi,

I have a problem, which only seems to apply to Firefox. I am a developer for a site which uses LetsEncrypt certificate. When I access it via Firefox (and only Firefox), I get the error message as mentioned in the subject.

I tried to understand why this occurs. A quick Google just leads me to an issue with the Microsoft domain, and what I can understand was a Firefox bug.

Trying to figure out if it is a problem with Firefox, or a problem with the certificate. Any thoughts?

I use different extensions and have been experiencing the same problem intermittently for the second year in a row. For example, I use the Highlight This extension and I need to enter data in languages other than English. The problem is that if I start switching (win + space) layout, the data gets erased (because popup close). Other extensions circumvent this problem by creating a separate page (uBlock), but many do not provide it.

This issue was already posted here without results https://support.mozilla.org/en-US/questions/1291870

Often when browsing I find that when i want to use spacebar it does something i don't want it to do, which is advance the page downwards, like the "page down" button. I'd like to change that to something else, like maybe the page down key. Thanks.

When downloading files, FF opens a window to file manager. The window enables user to choose the download directory. But the window extends past the right side of the monitor, thus the "save" button is not displayed. Thus, files cannot be saved.

I started using Linux Mint a few months ago, and since then have had issues with opening Firefox on startup. The attached image shows roughly what Firefox does the first time I try to open it after starting my computer. I usually have to close and re-open it 5-10 times before it will launch properly. At this point, I usually manually recover my previous session. Does anybody know of a potential fix to this problem? I have tried updating Firefox and have also tried uninstalling and reinstalling.

I lost my arrows on my scrollbar again after an update early last month. I tried adding lines to the gtk.css config files with no success unlike I've been successful doing in the past. It appears they are gone forever unless I can find another way to get them back. I noticed that the scrollbar arrows are gone on only Firefox and Thunderbird. As mentioned, this has happened in the past after some updates but in the past I was able to edit the gtk.css files in both gtk-2.0 and gtk-3.0 to get them back. Is there anything else I can try. I'm using the latest version of Ubuntu (Pop OS to be specific) and the arrows to the scrollbars disappeared around April 2nd for both Firefox and Thunderbird. I didn't notice any other applications where the arrows to the scrollbars disappeared. Is there something else I can try and a way to prevent this from happening in the future. This seems to be a common problem that happens every time there is an update.

Hi team, Can you explain me how exactly firefox sync works? asking because I thought by syncing it will save all the bookmarks with my account and I can use the same account to bring back all the bookmarks on another device.

I created an account on linux dual booted with windows and synced all the things I saved on firefox. Recently I switched to pop os and logged in using the same account. Expecting to see all the bookmarks on here too. But unfortunately it didn't worked. And all my bookmarks are gone. Is there any way I can recover those data?

Kind regards

Hello I have problem on my fedora workstation. When i click right button on the lowest bookmark on my list, the menu is hiding outside the screen and i can't see options.

Hello there to all.. I have been experiencing occasional crashes on the tab when left idle for a while!! I am using Ubuntu linux 22.04 when this occurs..! In Windows 11 or even Windows 10 x64 pro this does not occur to my knowledge at all.. So I am wondering why this is happening only on ubuntu linux 22.04 and not anywhere else??.. Anyways, Thanks for listening and have a great day ahead also..

Hello! I want to work with burp suit application but for work with it the foxy proxy need. when I turned on the foxy proxy it always gives me different kind of error messages such ass "The proxy server is refusing connections". I tried everything I could but to no avail.

Hello! I've been using Firefox as my daily driver web browser for at least a year, first on Windows and now more recently on Linux (specs below). The PC itself is the same, the only thing to change was the OS. Ever since moving to Linux, I've had this problem with crashing. I have two monitors and I will usually snap the browser to half of one screen while I do other things on the rest of my display space. However, most of the time when I try to drag the browser window off of its half of the screen, all of my Firefox windows crash, with an error message about not being able to send a crash report (see attached image). This has been happening with multiple browser versions, both the official repository release as well as the Flatpak. No other application has behaved like this.

From what I understand firefox now supports subtitles in picture in picture mode but when I use it for youtube it doesn't work. I have enabled the captions in the advanced settings and I have tried it with all my addons disabled.
