Firefox Support Forum

There is no userChrome.css in my profile.

If it needs to be created, where do I create it?

Yes, I searched for help. What I found was about userChrome.css to solve specific problems, but not what to do if it doesn't exist. Is userChrome still supported?

Thank you! Mark.

The credit card save/auto-fill option seems to have disappeared from the settings on Firefox. I previously had it set to 'off', but when there was an issue recently I found the option was gone - although the about:config was still showing credit card options. Has this option been removed from Firefox now?

I cannot use firefox. About the third or fourth tab or window I open hangs up, and then all of firefox hangs up. The triggering load can be from bookmarks or a new site. Have rebooted, re-opened: same problem. Have updated everything (including snap), same problem. Uninstalled and re-installed Firefox, same problem. Troubleshooting crashes and will not re-start

I noticed this morning that the radar site of theweathernetwork.com has stopped working on Firefox. I am running the latest Firefox from OpenSuse Tumbleweed. The strange thing is Vivaldi also has the same problem so I suspected it's not a Firefox problem. So I logged into Firefox on my two other Linux distros, Debian and Fedora and Firefox has the same problem on them!!. Strange that Vivaldi suffers the same problem, the radar site never loads in Firefox, and in Vivaldi it sort of loads but runs VERY slowly. I tried restarting Firefox in troubleshoot mode and it got as far as a page saying some browsers don't support the site and suggested I update my browser. It appears the radar site has made some sort of change which two browsers under Linux cannot cope with. Unfortunately the radar site of theweathernetwork.com is the best of all the sites available.

When I run Firefox from System Monitor, I get the following errors: Upon startup: glxtest: VA-API test failed: failed to initialize VAAPI connection Upon shutdown: glean_core::metrics::ping Invalid reason code start up for ping background-update, viaduct::backend::ffi Missing HTTP status Firefox opens on the left half of the screen, even though I keep it on the right. The right-click menu also opens on the left. Firefox will eventually stop loading new webpages. Upon shutdown, System Monitor and Nemo both become zombies, along with firefox-bin. I have to restart Linux Mint when this happens. I am running version 21.1, and Firefox 108.0.1. I have a crash ID: bp-19dffdf3-57ff-4dc4-8625-814d70221226

When you use Google's Translator, this application automatically adds a link to Firefox's history each time you modify even a tiny bit of what you are translating.

This means that sometimes, you can add 1,000 links within a day when you incrementally translate a piece of text, what is the default way to do.

Today, two minutes of that work generated 40 links!

Example of a typical link:

https://translate.google.com/?hl=de&sl=de&tl=en&text=Manchmal%20ist%20es%20wichtiger%2C%20etwas%20zu%20schenken%2C%20als%20wie%20es%20beim%20Adressaten%20ankommt&op=translate

And that was only a small piece of text!

In my history, there are in between 50,000 of these, despite regularly deleting many of them.

Even on a relatively fast notebook, deleting 1,000 links in the history takes minutes.

I posted the problem to Google Translate as a feedback many times, but they never answered.

Is there a possibility within Firefox to selectively get rid of this permanent garbage?

That would be wonderful.

Having this issue with Youtube since a few days ago, on version 115.0.2 and 115.0.3, and only for videos encoded in AVC/H264. VP9 and AV1 encoded videos have no trouble buffering, only H264 is affected. Happens with or without adblocker, and on different OS. Cookies cleared, no dice.

Video would load the first 20-40 seconds, then does not buffer at all subsequently once it reaches the end of that portion. I have to skip a few seconds forward for it to load the next 20-40 secs, then it would get stuck again.

I can get around this issue by either lowering resolution to 480p (which looks terribly unwatchable), or turn VP9 streams back on (which does not work correctly on my setup, there's a driver bug that hasn't been fixed).

The sure way, and strange thing, is that AVC/H264 videos load and buffer with absolutely no issue when I'm logged out of my account. Also, works with no issue in Chromium, even while logged in.

Anyone facing this or similar issue recently too? Is it still ongoing for you?

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico

Hi all, I use to update Firefox with my Linux distribution package: I build the new package then upgrade it on the system. Anytime at the first launch of the new Firefox just installed version, it opens a new blank profile instead of my usual profile. I can set my usual profile as default by launch Firefox Profile Manager. So after update I launch from command line terminal or through launcher bar:

firefox -p

And It starts up profile manager, then I choose my usual profile and check it as default one. After that, when I open Firefox again, it uses my usual profile as expected.

Now the question: - is there a way to automate this procedure so I have not to repeat it anytime after I update the browser?

PS. I noticed my "profiles.ini" file is populated with a lot of profiles sections, likely maybe anytime I update, a new one is added in here. I don't know if it is a regular behavior or not.

I tried the RPM and Flatpak Firefox, both in the newest version give me crashes when Loading Youtube, Invidious, Stud.IP, Nextcloud and more "bigger" sites.

It seems like an OOM error, but I have way enough RAM, 4GB/12GB used.

I tried the Flatpak and the RPM Version.

I tried troubleshooting mode.

I used the Arkenfox user.js on both installs.

My apologies if I am being a numpty, but I have been using Firefox for many years without issue, and recently (possibly after an update, but I cannot be certain), it has started to randomly freeze. I am running Ubuntu 22.04, and Firefox 119.0. I have demonstrated to myself that if I open a web page with links (but not always), and click on the link, I may still scroll up and down the page, but the mouse cursor never seemed to recognise the hotlink, and doesn't jump to it. The links will work on Chromium. I initially tried resetting the browser, thereby losing all my open pages, but that didn't work. That also removed all extensions ("all" two of them) and that didn't work. Firefox is now pretty much unusable. Any help to resolve this would be appreciated, as I cannot find any solutions online, and it seems I am not alone with this issue! Many thanks,

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

I have a 'site' that is just files on my hard drive.

I need to click an anchor link such as: <a href="file:///dir1/dir2/dir3/dir4">Store Your Files Here</a> and have Firefox open the folder dir4 with the systems file manager. ( In my case the file manager is Nautilus ) ( Ubuntu 20.04 )

I have seen this: http://kb.mozillazine.org/Links_to_local_pages_do_not_work but it does not describe a scenario that uses the file:/// interface.

It also does not provide any information about how the files will be handled.

I can get the folder link to work currently , but it appears with the: 'Index of file///...' in a browser tab.

Obviously you can not use that for anything useful.

The main goal is to open the folder and be able to use the system file manager to include more content for the site without having to navigate to the folder manually. The folders I want to display are buried many levels down without the possibility of having descriptive names. I have ~121 pages/folders in this arrangement , and each one has content for each page. I would like to add a button on each of the 121 pages that will open each of the pages content folder.

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?

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

Firefox 102.0.1 (Arch and Slackware 15)

Normal mode working fine no major complaints. However, Troubleshoot Mode is broken.

Arch: Browser goes to restart in safe mode. The window opens but no pages will load (local or remote). It looks like it is going through the motion (circular animation) but nothing ever loads. I have to get out of Troubleshoot Mode for pages to start loading.

Slackware: Browser goes to restart in safe mode but nothing else happens. No window opens. KSysGuard shows Firefox running with memory usage blank. I have to end process from KSysGuard.

Using DNS over HTTPS ADGuard and Don’t enable HTTPS-Only Mode

Arch: I tried using a new profile, refreshing Firefox, uninstalling and re-installing Firefox but the issue still occurs.

In Firefox I do log in to my account and sync in both Slackware and Arch.

Any thoughts? I can't seem to figure out why Troubleshoot Mode is not working. It was working. I just noticed it was not working anymore yesterday.

Tried downgrading Firefox to 101.0.1 and starting with a new profile but Troubleshoot Mode still did not work.

I'm not seeing any error messages in dmesg and I'm out of ideas.

Thanks
