Firefox Community Forum

I installed Firefox-ESR on my Raspberry PI and noticed that I cannot play Udemy videos. After some research I found that the Widevine plugin is missing and the OpenH264 Video Codec is also not installed. Following the instructions from similar issues didn't solve the problem. I ticked off and on the "Play DRM-controlled content" button but this only brings the widevine plugin for a moment and after that it disappears. In the network tab I see no activity when click on this button, i.e. Firefox does not send requests.

Additionally the OpenH264 Video Codec is not installed and never installs.

Any ideas how to solve this?

For a few months, I have encountered an issue with videos playback on my browser. On most websites (including Reddit, Dailymotion, and even some videos on YouTube), whenever I scrub back a video, it will stop for about ten seconds, while the audio keeps playing.

My current extensions are: Metamask, Bionic Reader, uBlock Origin, Return Youtube Dislike, and TWP Translate Web Pages. I have tried using Troubleshooting mode, but the problem persisted, so I think it's not because of my extension.

My OS is Opensuse Tumbleweed, with Firefox version 155.0.3. I didn't have this issue with Firefox ESR on my previous Debian 11 installation. I hope someone can find a solution for this, as it is extremely troublesome switching to Chrome whenever I want to watch videos.

I disabled graphics acceleration and I have the same problem. I tried several distros, it's the same thing each time, Firefox crashes and it's impossible to surf. could someone help me? I'm on opensuse thunbelweed

Hi, I have a disaster situation. I backed up my profile and then I wiped my computer running Ubuntu 20.04. I replaced it with Ubuntu 24.04. Now my profile seems to not be compatible with the Firefox installation on Ubuntu 24.04.

I followed this official instructions: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I put my old profile in the ~/snap/firefox/common/.mozilla/firefox/ folder and I set the correct values in profiles.ini. But sadly when I start Firefox all my passwords, extensions and history are not there. I lost everything.

I'm super desperate. Please tell me I can fix this somehow. Why is the official documentation lying?

Dear Mozilla Support, [please forgive my poor English - FRENCH is my mother tongue]

CONTEXT - I use a Linux (Peppermint) Live DVD to surf the Web, always on the same laptop. I do NOT use any hard disk inside that laptop, just the Live DVD spinned by a DVD player. Only the RAM stores data => fresh new distro for every session - years ago, I created a Firefox account, and the Sync worked perfectly, and allowed me to back up my Bookmarks AND my Opened Tabs (they are stored in Mozzila's cloud, and after each sign in and a sync, they reappear in the left panel). Regarding the Synced Tabs, the left panel used to store all the previous Live DVD sessions (generally with the device's name: peppermint's Linux... (IIRC). - i do NOT use several devices, and do NOT wish to sync date acreoss them. I use Sync to get my Bookmarks and Opened Tabs synced across successive Firefox sessions, day after day. I worked perfectly well.

PROBLEM Since a few weeks, I noted that despite login and sync, on the left panel - Synced Tabs are now empty: no tabs synced at all => so I cannot seamlessly find back my opened tabs from one session to another (if I switch off my laptop, then later restart a new Live DVD session) - see screenshot = https://imgur.com/LO6jWLYl.png - Bookmarks are nevertheless still perfectly synced (see screenshot = https://i.imgur.com/Td0nbY2.png)

Many thanks for you help. Kind regards from Europe.

Hello, I'm using Firefox as my default browser for a while now (10+ years) and I'm getting frustrated with this issue when using Azure Devops. Comments don't load at all and most pages take a long time to load if they load at all. Various features also take a long time to load or don't work at all (examples include adding a reviewer, referencing a story with #, etc.). Anyone else experience this?

It works well for maybe an hour, and after a couple of days it makes no sense anymore.

Now I'm using firefox containers with a container only for Azure Devops and seems working better but ... Curious thing is that it pops up and asks for credentials periodically every 5 or 10 minutes. Well, unless the boxes are already filled up with the credentials.

Thanks,

I have this ennoying issue since some months and didn't find a way of fixing it, even by completely deleting the app and removing all remnants of profiles before re-installing it. If I leave Firefox open when I shut down my computer, most of the time (but not every time!) instead of opening the last window with its tabs, Firefox displays the KDE Plasma's or OpenSuse's splash screen (which is a lamp bulb on a black background) and no menu). If I minimize the window, and maximize it again, it displays a screenshot of my desktop!... I can't do anything but close the window and re-launch firefox, but then the history of last closed windows is gone.

I have the same version of FF and the same version of OpenSuse on two other computers and never had this issue on them.

I would be grateful to anybody who could give me some tips to solve it or even investigate!

Thanks for reading. Erik

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

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.

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?

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.

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

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

My web site My web site allows user to login with .ejs Sign-up/Sign-in pages then delivers a React page. This works in Chrome and Safari. Https/SSL are provided by my host A2Hosting.

Firefox warns "Cookie “connect.sid” does not have a proper “SameSite” attribute value" when the cookie is set and then blocks the react page after login. If I enter the route that leads to the react page directly I can login and don't get the warning. In both cases the Storage tab in Dev tools shows the same settings for the cookie.

I made sure to remove any cookies for my site before testing the second scenario. I have tested this on Windows, Linux and Android versions of Firefox with the same results.

Here is my Express-Session instantiation ``` app.use(expressSession({

 store: new pgSession({
   pool: pool,
   tableName: 'session'
   // Insert connect-pg-simple options here
 }),
 secret: process.env.SECRET,
 resave: false,
 saveUninitialized: false,

cookie: {

   httpOnly: true,
   Secure: true,
   SameSite: "None",
   path: ['/'],
   maxAge: 60 * 60 * 1000 * 5
 }
 // Insert connect-pg-simple options here

})) ``` I've tried changing the path to include the react app route, I've added it to Cors white list and I converted it to open with an .ejs file instead of .html with no results.

Thanks for your support and for a great browser

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.

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,

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.
