After updating FF to v. 136.0 in Linux Mint 22.04, I noticed a problem with video playback in Facebook in some posts. A black screen appears with the message "Sorry, there were problems playing this video". The problem also occurs after disabling all plugins and deleting the user.js file from the profile. The problem does not occur after starting firefox in troubleshoot mode, but then hardware acceleration using the GPU does not work (Compositing: WebRender (Software)). I noticed that in version 136 there were some significant changes in the topic of video decoding. https://www.phoronix.com/forums/forum/software/desktop-linux/1524008-firefox-136-beta-finally-enables-hardware-video-decoding-for-amd-gpus-on-linux-by-default I have an NVIDIA GT1030 GPU with 2 MB VRAM.

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

Hi. I was just looking at Google Photos on both Firefox and Chrome. Chrome had a bigger picture because the window had only the tabs bar and the address bar, and Firefox has an additional title bar. I was wondering if it would be possible to remove the title bar so the picture on both browsers were the same size?

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

I am using an old Linux Mint version. I got messages that my Firefox needed to be updated.

I finally figured out how to do that and updated it. I started to use it. No problems.

However, the update did not change the default Firefox in the menu or on the taskbar panel below. If I click on them, I get the old version.

So when I restarted the computer, when I clicked on the Firefox shortcut icon in the lower taskbar I got the old version with the tabs that were on it. I had to go back into the Firefox file downloaded for the update in order to open the new version.

So, how do I get a working shortcut icon for the new version and get rid of the old version/icon?

Thanks.

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

I would like to disable automatic session restore completely. When I restart my PC, crashes or anything like that, I do not want Firefox to restore my previously opened tabs or windows. When I open firefox after a system reboot / crash, I want to only open my default home page. Only if I manually click History > Restore Previous Session should firefox ever restore my session, otherwise never restore my sessions.

I tried unchecking Settings > Startup > Open previous windows and tabs, and also tried following this article: https://support.mozilla.org/en-US/questions/1182594

My sessions still restores after my computer restarts or crashes.

Why do I want this? When I reboot my computer, I want a clean slate to start from scratch, not the dozens of pages (and other software) I had open from my previous session.

I am running linux mint btw.

Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

Hi, I'm not sure if this is a bug, or me not using FF properly.

I want Firefox in general to ask me, which profile to use when started. So in the Profile-Manager, I removed the checkbox for "Use selected profile without asking as startup".

Now, I wanted to create a shortcut for a specific profile, so I tried running `firefox -P "myProfile"` or even `firefox -p "/path/to/myProfile"`. In both cases I get the window asking me which profile to use.

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

Anthony Enzor-DeMeo wants to push way more AI onto Firefox. I originally became a Firefox user for the customizability, privacy, and security it offered in comparison to other browsers. How does Mozilla Firefox intend to maintain these features with so much AI slop? Will there continue to be versions of Firefox available without the AI components? I'm sick of having to turn off new data-stealing AI settings all the time on a browser I once trusted. I hate that I am now looking for other options.

This isn't so much a question as a complaint, I guess. Get your shit together, Firefox!!!

When setting up 2fa. I scan the QR code. Enter the 6 digit pin generated by google authenticator. Download my backup codes and enter 1 when prompted then firefox says sync time and try again. I am running Ubuntu and have an android phone. Ubutu is set to automatic date. time and timezone. My phone is also set to automatic date&time. I have enabled seconds display on Ubuntu and phone the are synchronized to the second. I have tried this on multiple computers. Google authenticator works with all 9 other 2fa logins I use it for. I have tried many times and asked AI what I'm doing wrong Grok said I am not doing anything wrong after walking through the entire process. I have tried clearing cache and deleting cookies, signing out and back in without success. Please help I use firefox as my password manager and love it but want it to be as secure as possible.

thank you very much. Thomas

With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:

• user_pref("browser.ml.chat.enabled", false);
• user_pref("browser.ml.chat.menu", false);
• user_pref("browser.ml.chat.page", false);
• user_pref("browser.ml.chat.shortcuts", false);
• user_pref("browser.ml.chat.sidebar", false);
• user_pref("browser.ml.enable", false);
• user_pref("browser.ml.linkPreview.enabled", false);
• user_pref("browser.ml.linkPreview.optin", false);
• user_pref("browser.ml.modelHubRootUrl", "");

Will this do it? What about:

browser.ml.chat.nimbus

Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?

Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!
