Firefox Community Forum

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.

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

When I try to backup my browser by going to settings, accounts/sync, press "Turn on backup", select a file, then press "Turn on backup" it gives me the error "We couldn't access your backup folder. Try picking a new location". I've tried on both librewolf (my default browser) and default firefox. I've tried many different directories, including ~/bkp/librewolf, ~, ~/.config/librewolf/librewolf/ke7g2g68.default-default/sessionstore-backups, ~/.config/mozilla/firefox/67ggi7is.default-release-1790353084599 ~/.config/mozilla/firefox/97cgns5q.default-release, ~/.cache/mozilla/firefox/67ggi7is.default-release-1790353084599, etc. All of them give the same error. I've heard that I'm not supposed to run browsers with sudo privileges so I haven't done that. I've never intentionally backed up my files as far as I can remember, so I don't know if this is a recent thing or not, sorry.

system info: -firefox version: 156.0.1 -librewolf version: 156.0.0_1-1 -os: arch linux -kernel version: 7.2.6-arch2-1 -WM: sway 1.12 (Wayland)

I do not trust google/chrome AT ALL and I have paid for Mozilla Firefox features such as VPN with another reputable antivirus software company but I can't find where or how to install a .csv file to import all passwords over for a permanent transition to Firefox use afterwards. Thank You!

I start FF in safe-mode. I open a local page which includes only one URL. When I hover on this link I see (`tcpdump`) a DNS lookup being performed for this domain. I followed the suggestions from Mozilla but I still see this.

How do I stop this access.

I use FF "156.0 (64-bit)" on Fedora 44.

TIA

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.

videos from formed.com using embed.vhx.tv suddenly stopped running on Firefox browser with message:

Firefox Can’t Open This Page

To protect your security, embed.vhx.tv will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. What can you do about it?

Using Mozilla VPN (Flathub version 2.39), Firefox Multi-account Containers won't let me assign a location per container as it did with the APT version - instead, under each container config it just says "Get Mozilla VPN" on a blue button.

But it does use the old config I had (so my old "US" container still exits in the USA, for instance).

This occurred on my old Ubuntu 24.04 system, using Gnome desktop; and also now on my new KDE system (Plasma 6.7.4) even if I tweak "configure permissions" in Discover to allow access to everything.

Any help gratefully received!

Hi.

My laptop keeps freezing and I suspect Firefox is the reason. It's rather new, I have had it for about a month and half.

I initially thought it was a Windows update issue and updated it but after some experiments I noticed it only freezes when Firefox is open. It doesn't freeze when another browser is used or when am playing video games.

I am currently on Ubuntu and it still happens. It's really annoying and because of this I am still keeping my old laptop. Yesterday for example it happened at least thrice.

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.

I have tried this on three different computers and last week it was working fine now I can't sign into my account on my new computer because I'm not getting a single mozilla confirmation email.

Not a single one. It's not been blacklisted or filtered or in my spam folder.
