Firefox-Hilfeforum

Hi,

first of all thank you all in the community for your amazing work on Firefox!

I have cloned my $HOME (including ./.mozilla/firefox/) to another Linux device.

Now I realize that changing the Firefox Sync device name on the new device would also change it for the other device when checking "Connected Services" https://accounts.firefox.com/settings. I also can only see the new device name when using "Send to device" from any device.

I guess I have to unlink my new device and somehow assign it a new device ID for Firefox Sync to recognize the new device. How can I do that?

Hello,

I have activated Firefox Sync and "delete cookies on close" and I have noticed that the URLs I have set up exceptions for do not sync across my devices, thus having to re-enter them on every device.

Is this by design or can I do something about it?

Thanks for any help

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

i am using Firefox Snap version 103.0.2 (64-bit) on Ubuntu 22.04. Whenever I try logging in to twitter, It shows a blank screen after I press login button after entering the password (Image is attached). I can login to other browsers I have installed on my laptop.

I have tried removing cookies of Twitter.com several times and even reinstalled snap version but the issue is still there. Any fixes for this? I can't keep switching browsers just for using twitter.

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

So, a preface. I rarely used this PC of mine, and thus the Firefox is rarely used as well. When i installed it, i turned on the option 'Open previous windows and tabs'.

Then, once I opened up some kind of offline documentations from Libre Office or Latex, which opened in Firefox. You know, the one where there is no tab appeared, and it just seems like a single pop-up window. I closed it without thinking.

Long enough, i forgot about that and opened up Firefox only to be met with that docs again. Okay, i closed it. But Firefox always started in this kind of pop-up window style ever since (attached). Changing the preference, even deleting the profile doesn't seem to do a thing.

Any recommendation to return Firefox to its original set?

For information: OS: EndeavourOS with Linux 5.15.94 DE: Xfce 4.18 with Xfwm 4.18 Version: Latest, Firefox 110, installed from Arch Linux repository

When I start entering an address or a search term into a new tab or new window I'll get "Search with Amazon" as top suggestion. How can I remove "Top Sites" suggestions on recent Firefox versions?

https://support.mozilla.org/en-US/questions/1285677 the solution proposed here, is not working anymore.

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Greetings:

First experienced: Friday, Sept 2, when using burpsuite/foxyproxy during a hackerone CTF.

When using other Vbox instances on the same computer I have the same issue. This issue is usually easy to duplicate when using dev-tools or by simply doing an image search and moving the mouse across the images.

Host: Ubuntu 22.04.1 LTS 5.15.0-47-generic #51-Ubuntu SMP Two different VGA controllers are present: Intel CometLake-S GT2 AMD/ATI Ellesmere Radeon RX

VirtualBox: 6.1.34_Ubuntu r150636 (Qt5.15.3) VirtualBox VGA: VMware SVGA II Adapter

Guest: Kali 2022.3 rolling 5.18.0-kali5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1kali6

Crashes have seem to involve input from the mouse and scroll function within the browser. Once, let us call it a glitch, the crash can either take place while continually moving the mouse around the browser's page or immediately outside the page with the mouse. The "glitch" is a coloration, usually pink or lime-green with characters printed to screen and then disappears. I have been unable to predict when the glitch will happen, thus no screenshot to help.

Steps I have taken:

Googled on the problem which led me to learn about the Firefox about:crashes function.

Viewed about:crashes -- seems to be a Renderer issue linked to llvmpipe or Mesa?

Checked basic system logs for host and guest for anything evident: syslog, kern, Xorg, messages, dmesg, daemon, journalctl.

Used Firefox troubleshooting and extended troubleshooting.

Installed Firefox 104 with same issue.

Reinstalled VirtualBox.

Search on Firefox Renderer issue [from crash report]

     I turned off performance settings, still have same crash issue.

Last Report ID that did not fail to upload: bp-740acc47-0ed4-44a8-851c-ff21b0220905

Ultimately, I am unsure if this is a Firefox, VirtualBox, or Kali Linux issue, but Firefox is the one that this issue is having a severe impact on. My head is spinning at this moment due to all the logs and information I have digested over the weekend.

I appreciate any efforts in helping me decipher what is going on!

Respectfully,

Steve

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

I'm currently running Firefox v 112.0.2 on Linux. I've had a theme installed for a while now that I really enjoy. It's a minimalist theme I found on github and then I topped it off with some colors that suite my desktop theme.

The ONLY issue I am having is with the dropdown menus. I can't see any of the list items and I cannot for the life of me figure out where to modify these colors. Searching has only gotten me more confused.

Photo is attached. I'm hoping that changing the text color here is an easy fix. The colors are all fine in other dropdown-ish menus, like bookmark folders for example.

Thanks in advance for any advice.

The issue appeared about two days ago. On the page https://index.hu/ the left click is not working from firefox. This is the most popular news site in Hungary. I also experienced the issue on other sites.

It is working fine from chrome and chromium. The issue is appeared on linux and windows 10 machines as well.

I tried to clear the cache but it does not help.

Please fix this ASAP or I have to delete your browser.

Hello

We have lost our developer access to manage an extension. Nobody knows which email address and account was used to manage the extension.

What is the procedure to get ownership of the extension ?

Thanks Frédéric Jahard

Hi everyone,

I've installed Debian 12 with Firefox 102.12.0esr (64-bit) from scratch instead of Debian 11. Just after it I noticed that all add-ons I used for a long time do not work anymore.

When I go to Menu > Add-ons and themes, I see all add-ons enabled. However, all of them do not work, and they even do not display their icons on the Firefox toolbar as they did before.

A couple of examples of add-ons that do not work: - Enhancer for YouTube - ImTranslator: Translator, Dictionary, TTS

I run Firefox via Firejail sandbox (like I did for years without any problems). All add-ons and settings came to my new system via Firefox sync. I tried to run Firefox directly (without Firejail) and nothing changed, add-ons still do not work. Also, I logged out of my Firefox sync account and reinstalled add-ons on Firefox running directly (without Firejail) and it did not help.

Appreciate your help - how can I enable add-ons in Firefox?

Machine information: OS: Manjaro Linux x86_64 Host: 80TG Lenovo V110-15IAP Kernel: 5.19.1-3-MANJARO DE: Plasma 5.24.6 Xorg WM: KWin CPU: Intel Celeron N3350 (2) @ 2.400GHz GPU: Intel HD Graphics 500 Firefox: 103.0.2 (x64)

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

1. Download Firefox and another application with direct input (Opera or Telegram for example)
2. Scroll Firefox
3. Scroll another application

I have a linux debian 11 o/s with up-to-date Firefox I don’t know which version at the moment it is whatever debian repo pushes down. I have 5 profiles on this particular computer with no previous issues. I decided to create another profile to be used for some test work and when I created it I then launched it and opened a few tabs to make sure it worked then closed. I planned on copying the profile files from another profile into this one so I went to the profile folder - /home/user/.mozilla/firefox/profile.names

Once there I saw my other profiles but could not locate this one so I went back to an open browser where I had the about:profiles page open and decided to delete that new profile and start over I figured maybe I accidentally saved it to a different directory. I hit remove it and it gave me the box asking if I wanted to remove files I chose yes I then go back to - /home/user/.mozilla/firefox but folder firefox was gone with all of my profiles all that was left in .mozilla was - /home/user/.mozilla/extensions and - /home/user/.mozilla/systemextensionsdev. Both of these folders - “extensions” as well as “systemextensionsdev” are empty. I go to the local directory for each profile and the data is still there for each of the profiles - /home/user/.cache/mozilla/firefox/profile.name.

The recycle bin is empty. A system-wide search for the profiles comes up with just the ones in the .cache folder. Back at the about:profiles page any attempt to open the preexisting profile results in a prompt asking me to create a new profile. I still have the one profile open and the addons are not working correctly. I did a bookmark export on this profile and doing so generated the “firefox” folder that had disappeared plus a profile folder using the same name of this open profile - /home/user/.mozilla/firefox'profile.name - it created a profile folder for this open profile using the correct name.

Any ideas on how this happened? Can the local profiles still in .cache be used to somehow restore the full profiles?

As you can see from the screenshot I don't have the new tab button (+), I've seen other users had the same problem in the past and the solution was restoring it from the customization page, but I can't find it there neither.

This question was asked, but the answer is outdated. This option no longer exists.
