Firefox Support Forum

I have fedora 36 Linux on my laptop and I have installed Firefox from the software store. The version in Help>About>About Firefox shows 99.0.1 (64-bit).

I am able to play videos on Youtube but no video or GIF is playing on Twitter/Reddit/Facebook.

I have installed media codecs as per this fedora help

My autoplay setting look like as per the attached image. I do not have any extensions except Bitwarden on Firefox.

I also tried playing videos on Firefox 100 by downloading it directly from firefox website but faced the same issue.

After an update today, private browsing windows now are a different color than the other windows. I don't want them to be a different color. How do I change them back to the same as the other windows?

Also, how do I remove the extra text label next to the private mode icon, and just generally put things back to the way they used to look?

I'm using Firefox in Ubuntu 22.04.2. I recently update to 112.0, then 112.0.1

With both versions, the scroll bar is not available on some sites which used to work in previous versions. Items which are outside the initial viewing area are not visible.

Is anyone else affected by this issue?

I use Firefox to develop my organization's CMS, which uses HTTP Basic Auth. This stopped working suddenly - no basic auth prompt is shown as of 16 Feb 2022. There's no error in the window or console, my server logs a 401 as expected but I've no way to log in. It works fine on other browsers.

Presumably, this is due to the fact that the CMS runs on HTTP, not HTTPS.

Is there anything I can do? We need to keep this running on port 8080...

Setting `widget.non-native-theme.enabled` to false no longer works; I still get Firefox's default styling for controls and widgets.

I use a custom GTK3 theme in my environment that I want to apply to Firefox. The above setting works in 91 ESR, and broke with the upgrade to 102 ESR.

A custom user chrome stylesheet would be too painful.

Note: You can revert page styling to defaults in View -> Page Style -> No Style.

Problems with slowness and crashing. Checked manage data and found this message: Your stored cookies, site data, and cache are currently using 17,179,869,184 GB of disk space. Cleared yahoo.com and yahoosandbox. A few days ago it was google.com causing this same absurd data message. v 94.0 on Linux

FireFox: 107.0 (64 bit) Mozilla FireFox for Linux Mint OS: Linux Mint 21 Cinnamon

Issue: On this FireFox latest version, the download window cannot be resized to smaller than (roughly) 1/4 of entire screen. (screen-shot attached.)

Attempted: Mouse left-click grab of all corners & sides to drag window smaller - failed!

Note: Download window can be resized *bigger*, showing this window has now been coded with a very large minimum size that is almost 1/4 of full screen

- this was not the case in previous versions.

Micro-annoyances add up, people switch to Chrome (sorry to use the "C" word!)

Hello, This issue might or might not be related to [other issue] I have since I updated Ubuntu 20.04 to 22.04 and therefore updated my Firefox to 104. I can't login anymore on Letterboxd since the update. It's not a problem of username or password. When I click "Sign in", nothing happens except a page refresh, but I'm still not logged in. Other strange behaviour on that site since the update: most of the images don't appear. For example on this page : https://letterboxd.com/films/# all the movie covers are just blank.

The website does work properly when using Firefox in private mode though (both login and images work fine), so this makes me think it's related to my other issue mentioned above.

OS: Ubuntu 22.04 Firefox 104.0.2

EDIT after posting this question: I just found out that I can't login on Google either. I enter my username, password, then it asks me to validate on another apparel that it's really me, which I do, and nothing happens so I can't login. It works normally in private mode.

Hello,

I am running Firefox v101.0.1 (64-bit) on Linux (Pop!_OS, installed as a flatpak). I am using the default system theme in dark mode, though switching to the Firefox dark theme or other themes does not change anything. When I allow the Menu Bar (File, Edit, View, etc.) to be present, the browser tabs on the next line are aligned correctly, going all of the way to the left. When I uncheck the Menu Bar, however, a gap appears to the left of the tabs. I have not seen this behavior on Firefox in other environments (Debian, RHEL, Windows), and I'm wondering if there's a way I can remove that gap. I have attached screenshots showing how the tabs are aligned with and without the Menu Bar.

Thanks so much!

i start a vid in youtube. the sound has static. if i open another window, even on a site that doesn't play video or sound, the sound and picture on the first window instantly get out of sync. the picture runs about 2-3 seconds ahead of the audio.

i have not customized the setup. this is a "stock" configuration. i have lots up upload, download speed. 20Mbps up, 80Mbps down.

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?

I tried signing into google, but when I type in my gmail address and click next, nothing happens. I tried with chrome and it worked. I cleared my cookies and cache, updated and reinstalled firefox and the problem persists. This first happened around a week ago. I use arco linux with xfce. Thanks

Just (~20 minutes ago) updated 102.0.1 (64 bit) and now there are white bars across the bottom of each firefox window (see screenshots) except for support.mozilla.org or mozilla.org addresses. Any idea what is going on and/or how to fix it?

Hi all, i have a Firefox 98.0.1 on Linux Mint 20.3 Cinnamon. It's been running perfect but since yesterday when i try to visit accounts.google.com to log in to Gmail or visit youtube.com the tab always crashes. The tab crashes as soon as the site is loading so i'm not even entering anything. I have Windows 10 running on the same machine, problem does not occur there. I also have Chromium on Linux, problem does not occur.

I have tried clearing cache, disabling all plugins, disabling hardware acceleration, creating new profile, refreshing Firefox, running Firefox in troubleshooting mode, completely removing Firefox including hidden files.

I yesterday had a problem with the file system or something. A black screen showed some error message, i quickly googled it, typed in something like sdfk or sfdk and it repaired something broken on the hard disk i guess...

All crash reports have the signature "_dl_relocate_object"

Can anyone help? I've submitted a crash report with the ID 1bb292d9-61e5-4af1-942d-b5bee0220318 Thanks

edit: I also ran a RAM test with memtest86, it ended with not a single error. After trying to revert to a previous system snapshot i ended up with a black screen and code lines telling me to install a kernel first and some spooky grub mode. In the end i re-installed the whole OS, now it works.

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 old Linux computer died and I have removed the still good SSD from it. I have installed the latest Firefox on my new computer and would like to restore the bookmarks and other saved data to the new computer.

I am running Ubuntu 20.04, the old computer was on Ubuntu 18.04.

Can these things be restored, and if so what do I need to do?

I just updated Firefox to version 81.0 in Linux, Windows and Mac, but the credit card autofill option is still missing from the Preferences menu.

I followed the instructions from here:

Yes, I am located in the US.

Nightly is working really good in my Android Phone. Now I would like to install Nightly in my LinuxMint Desktop. I found a page at https://www.linuxcapable.com/how-to-install-firefox-next-beta-or-firefox-quantum-nightly-on-linux-mint/ But cannot install with all those commands. So what is the best way to install Nightly on my LInuxMint? Without all the commands and things I don't understand. I am 82 years old and cannot always do such. Thanks for your help.

Hello, when I try to login into various services, such as Outlook, the browser fails to log in and does not redirect to the logged in page. I'm using Firefox 98.0 on Manjaro 5.15.25-1. I tried uninstalling firefox and deleting all the data but the problem remains the same.

I haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.
