Firefox Support Forum

i want to zoom in and zoom out screen content using zoom css according to my screen it's working fine in Google crome browser but not working in Mozilla Firefox browser

https://prnt.sc/brKa31ZMK1LE

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.

When I try to install Firefox on my Steam Deck (Which came with the installer). It doesn't open. It just says "Cound not open appstream://org.mozilla.firefox because it was not found in any available software repositories.

Please report this issue to the packagers of your distribution." It shows it every time I open the installer ever since I got the thing.

I was using Ubuntu before. I was using firefox and i had lots of recorded logins in that browser. I sign in with my current account and i opened sync including the password and login. Recently i changed my distro, i am using Fedora right now. I log in my firefox account, yet my passwords and logins didn't came back.

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

Hi,

On what port does the firefox extension update on does it use port 21? I need the extensions to be auto updating like set and forget knowing that my firewall is not blocking the required port

Thanks

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

I'm using Firefox 119.0.1 on Ubuntu Linux.

Thanks!

I have found that Firefox does not play some audio files, for instance on Wikipedia and WaniKani, such as the audio on https://en.wikipedia.org/wiki/Erhu and https://www.wanikani.com/vocabulary/%E9%9F%B3. When inspecting network activity I can see that an attempt is made to load the audio on Wikipedia, but it does not play. On WaniKani however, no attempt is made. (WaniKani uses .webm for sound, maybe that has something to do with it?) The problem appeared after the update to Firefox 118 and persists in private browsing and troubleshooting mode, but does not occur in GNOME Web.

Debian 12 (Bookworm) Desktop Firefox 115.4.0esr (64-bit) & Firefox 119.0.1 flatpak (64-bit) add-ons: uBlock Origin (Version 1.53.0), Privacy Possum (Version 2019.7.18) , Add custom search engine (Version 4.2), Search Engines Helper by Soufiane Sakhi.

when using custom search add-ons after the most recent update none of the options I have tried work. As listed i have tried two with different search engines.

when I try to click drop down menus on rpg mo, like settings/game options or anything in the gear drop down menu it wont let me click. I can't play rpg mo is there a reason for this like is it not html they are using but it works on windows? I am using suse linux leap.

If I lock my machine for more than a few minutes and then log on again, it's always the same. I unlock my system and feel some kind of slowness in Firefox. When I switch from the currently open tab in Firefox, the new tab is highlighted in the tab bar, but the content part of the window is frozen. If I quickly open htop, I can see that the main Firefox process is suddenly using about 130% of my CPU. The only solution I have found is to quickly open htop after unlocking the system, send a SIGKILL to the main Firefox process and reopen it. This way the freezing, slowing problem is nowhere to be seen.

I am running Debian 12 with Firefox 115.4.0esr (64-bit). I have more than enough RAM and CPU.

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

I have DNS over HTTPS enabled and set to Default Protection in Firefox.

According to the following article (https://support.mozilla.org/en-US/kb/dns-over-https?as=u&utm_source=inproduct#w_why-would-a-network-tell-firefox-not-to-use-secure-dns) DNS over HTTPS should automatically switch to "Not Active" when connected to a VPN.

I am using the NordVPN CLI for linux and have found that when I connect to the VPN, Firefox DNS over HTTPS stays active and does not switch to "Not Active" like it is supposed to.

Does anyone know why this might be happening?

Hello, I did something stupid. I was trying to set up the dark/light theme via cli, and I asked openai about it.

It suggested this command:

echo 'user_pref("lightweightThemes.selectedThemeID", "firefox-compact-light@mozilla.org");' | jq -s '.[0]' > ~/.mozilla/firefox/*.default-release/prefs.js

Which resulted in the following error:

jq: parse error: Invalid numeric literal at line 1, column 11

When I opened mozilla, my profile was reset, and websites won't load (except this one!). They just hang there loading forever. My internet is fine, chromium works perfectly.

So how do I fix this and is there a way I can recover my profile? (Yes I know I should've made backups)

Dear Friends,

Trust all is well...

PLEEZE put an end to this mystery. Can you BLOCK YOUTUBE ADS or not? If so, how is that accomplished.

Many of the extension are not safe even dangerous to use.

Thank You!

Best, Ralph
