My Dell Precision Laptop from 2019 runs a frequently updated Ubuntu 24.04. About one or two weeks ago, after one of the latest Firefox updates, i noticed that video streaming produces rectangular flickering in rapid sweeps. ( Also fast scrolling large text websites produces similar flickering, I think I would have noticed it before...) . If you detected it once, you see it always again... :-( First I fiddled around with the nvidia settings because the driver was also recently updated, without much success. Playing locally stored videos, e.g. with VLC media player, still works fine, so the nvidia driver is not the problem i think. Yesterday I installed Chromium and the video performance is fine! As good as with firefox some weeks ago! So it must be one of the latest updates, that causes the problem. Generally I like firefox more than chromium. I like the control you have, e.g. via Add ons.. So I hope that the firefox performance will increase again... Thank you for firefox! Florian Mengedoht

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

I'm using Firefox from the official Ubuntu repository (packages.mozilla.org). I have used the (very cool) "translate page" feature successfully, but for some reason it doesn't seem to work on https://wiki.openstreetmap.org/wiki/NL:Basisregistratie_Adressen_en_Gebouwen which I'd like translated to English. Even though Firefox thinks the page was translated, only one of the headings seems to be in English.

I would like to understand how to troubleshoot this and help you improve this great feature. Thank you in advance.

Anyone succeed with running Firefox in headless mode under Ubuntu?

I tried:

firefox --headless --safe-mode -P headless https://quan.hoabinh.vn

but got this error:

[12545] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

• • • You are running in headless mode.

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

I installed Firefox as from "https://packages.mozilla.org/apt" repo.

I am using a local library and it comes to me that I find some activities that occur whilst working on my daily tasks and wonder, I would really like to run a diagnosis in my tasks and activities and check if there are no spams running me dry.

Hi,

I'm using Firefox 155.0.1 64bits, in Linux Mint Debian Edition 7, x11, XFCE4. I have a Belgian keyboard. I have noticed that the dead keys aren't working any more when typing text / messages from within Firefox. I don't have this problem in other browsers or applications.

I used xev (x11 utility) to check if the dead keys were working and tested a different keyboard, all work. I tried to start Firefox in safe mode or by starting Firefox from a terminal with the following commands: - env GTK_IM_MODULE=xim firefox - env GTK_IM_MODULE=ibus firefox

But nothing worked. The dead keys aren't working. The issue must come from Firefox for it is not an hardware issue (tried different keyboards) nor software (dead keys work in other applications).

Any idea to fix this ?

I play https://crazyshooters.com/ and https://crazyshooters2.com/ a lot! But the game became laggy since Firefox 148 and my ping spikes up. Other browsers play fine. I am on Linux Mint if that helps. (147 and below run fine)

I deleted the Firefox on my Sony mobile phone.

I go to play store wanting to download it but I can't find it from my Sony phone. Can you please help.

Thank you.

Louise.

I thanks you for giving me the ability to use use firefox wihtout AI (by turning it off in the setting, you did it, love you, love you, love you), so really I can't use AI, I don't use regular trnslation that AI enable like google traduction, and chatgpt etc.., I see from my use of them start, the soft skills go very below, they really kill my soft skills I am trying to avoid them as much as possible, and thank you for giving me a choise,

Dear Sir I had Firefox on my Sony mobile phone for quite long years, I deleted it by mistake today, how can I get it back. My Sony mobile phone is Android 7 . I tried to recover it from my computer and I got QR CODE I took a picture then do not know how to do after that. Can you please help. Thank you. Louise.

Hello

I just activated the Mozilla built-in VPN (beta).

I wanted to ask about the whitelist and blacklist features.

I can see currently, that there is an option to add specific websites in the VPN settings, and that the tooltip says "Use VPN for all websites except the ones on the list", acting as sort of a whitelist for the VPN features.

However, I am wondering if there is an option for a blacklist, where i would like to keep VPN off by default for all websites, except the ones on the blacklist.

For a simple example: wowhead.com is blocked in my country of origin, so I would love if i can turn on the VPN for ONLY that website - and keep the rest of my traffic on other websites without the vpn.

Hello AMO team,

I am the developer of two add-ons published from my old account, which I can no longer access: I lost the authenticator app used for two-step authentication, and I have no backup authentication codes or account recovery key for that account. Password reset is therefore impossible (the reset flow requires a TOTP code, and no recovery key exists on the account).

I would like to request an official transfer of ownership of the following two add-ons from the old account to my new account:

1. Admin-panel quick access - https://addons.mozilla.org/addon/admin-panel-quick-access/ (add-on id 2650700, guid {dc8766bb-be8a-4bf9-aec8-6bf114d6ed24}) 2. TripleKeep - https://addons.mozilla.org/addon/triplekeep/ (add-on id 2654061, guid {ddb290f5-c226-4a22-9dd0-b1731169d15b})

- Old account: https://addons.mozilla.org/en-US/firefox/user/15677483/ ("Shepel", registered 2020-02-19) - New account: https://addons.mozilla.org/en-US/firefox/user/17480927/ ("Shepel Pavel", email [redacted] @mail.ru)

Proof of ownership:

- The support email listed on BOTH add-on listings is [redacted] @shepel.net - an email I control and have full access to. I can reply to any verification message sent to that address. - Both listings link to my GitHub repositories, which I still control: https://github.com/shepelpavel/go-to-admin (branch firefox) and https://github.com/shepelpavel/triple-keep (branch firefox_ver). - The manifests in those repositories match the published versions exactly: "Go To Admin" version 1.3 (= published version 1.3 of admin-panel-quick-access) and "TripleKeep" version 1.4 (= published version 1.4 of triplekeep). - Commit history in those repos (author [redacted] @gmail.com, dated 2020) matches the AMO submission dates (2020-07-02 / 2020-07-23 / 2020-08-11).

I have intentionally not re-uploaded these add-ons under the new account to avoid GUID conflicts - I am requesting an official ownership transfer instead.

Please let me know if you need any additional verification. Thank you!

Best regards, Pavel Shepel [redacted] @shepel.net

System: Linux Mint 22.3 Xfce Firefox web-browser: mint-001 - 1.0 _ 155.0.1 (64-bit) Hardware: Both on my Desktop and Laptop computers.

Since the recent updates, 1-2 weeks, every time I try to enter a character via Unicode insertion, CTRL+ALT+U, the character does not insert but a row break. I made a video about it: https://youtu.be/OP9UCGpZdEc

This happens in every website I use; mostly likely on every website.

Is there anything I can do now?

Thank you for your time reading this. 🙇

I have issues discerning where each of my desktop windows are. To help with this I use gtk.css styling to add a border on all of my desktop windows. For some reason, Firefox does not draw this border.

Is there any way to apply a border around the Firefox window?

I was able to get a border around the navigation area of the browser by adding a userChrome.css file but I don't see any way to do the same thing for the whole window.

Can this be done in userChrome.css? Using gtk.css styling? Any other setting or file?

I am running Firefox 155.0.1 on Ubuntu Linux 26.04.1 LTS using the Gnome 50 desktop.

Hello everyone.

Firefox updated today. I don't know—maybe some people like the new design of the tabs, the buttons in the drop-down menus, and the gradient borders around the active tab and the tab bar itself. But I’d like to revert to the old interface. How can I do that?

Thanks!

I get this dozens of times in a session. As far as I can tell it doesn't affect performance. I found a solution about using notification-daemon for Ubuntu from 4 years ago that doesn't apply to Slackware. I like to eliminate error reports. I don't even know what this means. Knowing would be great, even if I can't stop it. Just eliminating the error report, if it's harmless, would be nice.
