Locking this thread, please continue here: [/questions/1572529]
I've been using alt+a to open new tabs in a multi account container for a long time. Recently that shortcut stopped working possibly with the update to v148 as indicated in this reddit thread.

alt+a is not listed as a shortcut in about:keyboard or in about:addons > manage extension shortcuts or in my ubuntu shortcuts nor in any software I can think of thats running. I've disabled all my add-ons except multi account containers to no avail. I can change the shortcut to another and it works fine.

Why would just that shortcut stop working? What else can I do to diagnose the problem?

Recently I've noticed that some web sites are displaying text in very washed-out colours or on backgrounds of similar colour to the text. This produces a low contrast ratio and makes the text very hard to read. I tried setting the text colour in Firefox settings, but this seems only to affect text where the web site does not explicitly set a colour. Is there any way to ovcerridethe web site's choice of colour?

I set up firefox using my customised user.js, and I have been able to configure everything just as I want except for "Search Shortcuts".

Are there Firefox "preferences" (in the about:config "preferences" database) for the 10 or so "alternative search engine" entries (shown in about:preferences#search)? If not, is there any programmatic way that I can edit these "alternative search engine" entries so that I don't have to manually disable and/or remove them every time I install Firefox on a new machine?

TIA.

Environment - OS: Omarchy - File manager: Nautilus (running as --gapplication-service) - Desktop portals: xdg-desktop-portal + xdg-desktop-portal-hyprland (+ gtk fallback) Firefox: latest stable from Arch repositories

Observations Only one Firefox process is running (pgrep -a firefox). Only one Nautilus process is running, but it receives two open requests, resulting in two windows. The issue does not occur in Chromium/Chrome, which opens only one window. Running xdg-open <file> manually opens one Nautilus window.

Portal logs show GTK being chosen as last-resort fallback, but system-wide XDG configuration appears correct.

Question

Is this a known Wayland/portal bug in Firefox? Are there recommended debugging flags or patches to trace the duplicate launch request?

A pop-up suggested that I use profiles to organize and it sounded like a great idea but then after making profile I was having trouble getting tabs from one page to another. Then I discovered that I had to log in my accounts onto every profile I made and it sounded like a terrible idea, so I tried deleting all my profiles to get it to revert but now that I open the browser it shows me to make a new Profile. So, I want to know how can I revert back to using Firefox Without the use of profiles like I was before clicking the pop-up

I don't really want to disable storage or ALL cookies. But I DO want to COMPLETELY sanitize on shutdown. While this policy is effective AND network.cookie.noPersistentStorage in config has been set True, NEITHER stops Persistent Storage nor cleans it. ONLY manual cleaning (deletion) of persistent storage is available in Settings: Privacy & Security: Manage browsing data. There is no other option available that I can find. One solution suggested a setting that both disallowed cross-site cookies AND isolate other cross-site data but there is no setting like that. There are TWO separate settings for that. Besides, that is not what is wanted.

How can I either completely disable persistent storage - or, more preferred is to completely clear persistent storage upon quitting?!

I have everything else cleared on quitting but persistent storage is indeed persistent. If I have to, I will disable it completely (not preferred) but do NOT want to disable ALL storage use.

Why doesn't network.cookie.noPersistentStorage not work? Or, if it does, what does it actually do?

I would like a policies.json entry for this as I already employ the file in /etc/firefox/policies as described. This is the preferred method for multiple users.

I am using Ubuntu and Firefox Snap for Ubuntu 149.0.2 (64-bit). Let me know if other information is needed. Thank you.

I tend to have long and extensive conversations on Firefox's Copilot AI but I've run into an issue that makes this more difficult. When I press CTRL + F to search for text through a chat, it only searches on the webpage I have open on the right. I was wondering if there is a feature that exists that does this that I'm not aware of, and if not, maybe that could become a thing later?

Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

I run Firefox on Fedora Linux (Silverblue). For several releases I've noticed that the reader mode only displays the Close Reader View, Text and Layout, and Theme options and nothing else i.e. no content.

When I run it in troubleshooting mode, it works. I've tried disabling all my extensions, deleting all my extensions,restoring the browser to default settings but nothing makes a difference. I'm always on the latest release (currently 147.0.3). I currently have multiple profiles, but it didn't work even before I rebuilt them. I'm out of ideas.

Any help is appreciated

Whenever a Firefox extension connects to a particular native application for the first time, a dialog opens that looks like the attached.

I've pressed "cancel" on this prompt.

Where are the "privacy settings" I can use to revert this ? Nothing in the "Privacy & Security" section looks like it, and there's nothing in the "about:extensions" sections either.

In recent activity if I click the kebab menu and select Delete from history the thumbnail disappears to reappear again after a couple of seconds. Only after repeatedly clicking Delete from history the activity actually disappears.

Is this normal behaviour?
