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.

Hi everyone,

I use Firefox for most of my research and frequently save articles, documentation, and webpages for work. Is there a simple way to turn this content into presentation slides without copying everything manually? I recently came across MagicSlides AI PPT Maker, which seems to generate presentations from existing content, and I'm wondering if anyone here has tried it or knows similar tools that work well with Firefox.

Hi 🙂 This is a follow-up to https://support.mozilla.org/en-US/questions/1511440.

The problem is this: support.mozilla.org is a site intended for asking support questions, and it is very inconvenient not to be able to use extensions that assist with typing (notably Unicodify and Clippings).

i have 2 suggestions to do:

1) Let the user choose whether to keep extensions enabled (in which case support.mozilla.org is not privileged, the user cannot send "Troubleshooting Information", and there is no security vulnerability), or to send "Troubleshooting Information" (in which case extensions are disabled).

2) Review the design of support.mozilla.org in a way that a subdomain like ffinfos.support.mozilla.org is privileged instead of support.mozilla.org, Firefox sends "Troubleshooting Information" to ffinfos.support.mozilla.org, and extensions are enabled on support.mozilla.org but can never interact with data that Firefox would send to ffinfos.support.mozilla.org.

What do you think about this?

Sites like NBC and USAToday tell me to disable Adblock Plus. After I do this, I hit refresh. These sites still say ABP is active and to disable it. This does not happen in Chrome.

SerpClix ClickSense could not be verified for use in Firefox. Proceed with caution.

How can I get SerpClix verified? I can't sign in to my SerpClix profile.

I have had the YouTube Nonstop extension for a few months. It was great. It let me play playlists without stopping every few songs. Then today it quit working.

I turned it off and back on but that didn't work. I looked for an update but the last one was 2 years ago.

I haven't tried removing it and reinstalling it. I guess I will do that. Anyone have any ideas?

I see people communicating with the developer on the App store, but I can't find out how to do that. I don't see a link to the developer.

Any help would be appreciated.

After realizing what was being done to my PC, I unplugged it to stop the hacker. And I have since been able to recover my program, except for my ad blocker. Before this unusual encounter, I was using a free ad blocker. I want to restore it to its original status, if possible. Thank you for any help, Leman H Wilson at 7:09 PM 6-3-26

I am trying to get Russian language spellchecked.

I went to this url: https://addons.mozilla.org/en-GB/firefox/addon/russian-ru-language-pack/, installed the pack. Re-opened the browser. But nothing seemed to changed.

I use English locale.
