Firefox Community Forum

I'm wondering if there's any way to have a button toggle for a setting exposed via about:config?

The reason for my ask is that I currently use a second Firefox profile, where full-screen-api.ignore-widgets is set to True, in order to have full-screen videos inside a firefox window, meaning I can fully expand a video into the window that its open in, without taking up the entire screen. Extremely good for productivity reasons.

Now, the only slight issue that I have is that sometimes I wanna easily swap back without needing to move the video tab to my main profile - and hoping that it's possible somehow without exposing myself to lax security practices - I found it might be possible when using fx-autoconfig - but it does concern me when it states "Please note that malicious external programs can now inject custom logic to Firefox even without elevated privileges just by modifying boot.sys.mjs or adding their own script files.".

I essentially just want an true/false button for the full-screen-api.ignore-widgets setting instead of needing to swap profiles/manually enter about:config to swap the boolean value back and forth.

I purchased Dell desktop computer, Windows 11, I installed Firefox, and I made Firefox the default browser via Firefox and the computer's settings.

I selected default dozens of times. Each time it stays the default for a while and then another web browser becomes default.

I then again select Firefox as the default web browser, both ways, and it stays that way for a long time or a short time. A few minutes ago, after the selection, the settings window for the app page flashed and Firefox was no longer the default browser.

I have Google Chrome and Microsoft Edge installed for the few times that Firefox does not work on a particular website.

What gives? Thank you

So I had Mozilla account with Syncing Enabled before I reinstall windows (I had only Zen browser on my pc), and after reinstalling windows I downloaded Zen and got in my account, but after pressing syncing there is no passwords, no history, no bookmarks, literally no data that I had before, does that mean I lost all my data?

So I wanted to reinstall windows, I had Zen browser and Mozilla Account with syncing enabled (but I only had zen on my pc), and after reinstalling windows I downloaded zen again and got in my account and tried syncing it my literally nothing got synced, no passwords, no bookmarks, no history, and I got no file to manually back it up. Does that mean I lost all my data?

I can't Import bookmarks from chrome, the option is missing. Everything else worked, and the option is not "hidden", when I clicked to import bookmarks were not imported.

macOS Tahoe, Firefox 152.0.3 macOS settings include "Appearance - Auto"; i.e. system switches from light to dark at sunset. While the "top area" (tabs, address bar, bookmarks bar) of Firefox follows this - some of the pages themselves do NOT???

I found this website which was at top of the search results. I tried to follow it, but it seems to be badly outdated in certain key respects: esp wrt a setting called "ui.systemUsesDarkTheme" in about:config. I set this to "True", but may have screwed this up!! First question: Should I "reset" this somehow?

Finally: To get at the primary question, there are two "sub-questions" that may explain my confusion more clearly:

1. Is there no ***simple way*** to get Firefox & webpages I view to follow macOS Light/Dark appearance?? What are the CORRECT steps?

2. Do individual webpages have the ability to "decide for themselves" whether or not they will adhere to the system light/dark settings. This may well be an officially "stupid question", but while "most" webpages remain "Light" (including this Support page), a few pages appear dark.

Thanks, ~S

I came to know about Firefox Widgets but can't see any on Firefox 152 on Windows 11 desktop. The option Allow Firefox to improve features, performance and stability between updates is already checked (Screenshot attached) as suggested by users.

I have a home server 192.168.0.240 in my local network. Firefox does not let me in to my own pages. On the address line appears text "Not secure",

I have found no way to get in. I have there REALLY IMPORTANT TOOLS AND MATERIAL and I need it AS SOON AS POSSIBLE !!!!

This is really stupid. I have used these pages until this weekend. I have had this problem many years, but always found some way to make it work. I am NOT going to buy a certificate to every server I have home. it costs $$$$.

Hi, after my firefox updated the media buttons from my keyboard only seem to work intermittently with it.

At the moment they don't work when firefox is minimized, but yesterday they didn't work when maximised either.

No problems in Chrome or local media players.

media.hardwaremediakeys.enabled is set to 'true' in about:config

I am currently listed as on version 152.0.3, 64 bit windows.

I am using the current version of Bazzite. When I run Mozilla VPN, I just get a blank window for a few seconds, then it asks if I want to force quit. Uninstalling and reinstalling, and restarting my PC, do not seem to help.

I recently reinstalled Bazzite on this PC, and Mozilla VPN was working on my previous install.
