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

When entering full screen mode it's only inside selected window. Also affects youtube player. Pictures when in full screen mode (using F11 key): https://imgur.com/a/gp3yqCC

Whenever I use Firefox 109.0 (on Ubuntu 22.04) to transfer money between savings and checking in my online banking account, I get a window pop-up that says "No Apps Available". This is something going on my bank's servers and shouldn't require Firefox or any local helper apps on my end to do anything. I will post the window that pops up. Has anyone else encountered this? And is there a way to disable these pop-up?

Hello,

After installing Firefox (103.0.2) on a clean install of Manjaro (21.3.7) Gnome (42.4), I started noticing that mouse hover effects such as highlighted tabs, UI of a video-player appearing etc. are delayed after my PC exits hibernation (I am not sure if that is the only cause and if that really IS the cause). Weirdly enough the select menu I used to answer the "Which topic best describes your question?" question to create this post experiences no delay in highlighting the hovered element. Relaunching Firefox fixes this issue temporarily.

To be clear this is no performance issue since everything except mouse hover related interactions are fluid.

Thanks for helping out

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?

Maximizing and minimizing are still normal, but Firefox windows could not be dragged now.

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 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 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.

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?

Firefox version: 101.0 (64 bit) OS: Fedora 36

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.

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.

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?

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.

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?

My windows install in my dualboot pc is unable to open at the moment, I can access the windows files from my linux. But i need the firefox data on that pc that I kept. I don't remember which email I used on that account so I'm kind of stuck on getting my data from online. Is there a way to recieve all the data from another drive without opening firefox?

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?
