Firefox Community Forum

Is there a way to fully disable HDR support in the latest Firefox (138.0.1)? I use it on Linux/Gnome (wayland) where even though HDR support is disabled system-wide (gdctl confirms that) as well as on the monitor, Firefox insists on displaying YouTube videos in HDR resulting in washed out colors.

Looking into the issue I found that disabling the config flag layout.css.video-dynamic-range.allows-high seems to disable HDR but I'm not sure if this is the appropriate way or if there is another switch I currently don't know.

Any help is welcome!

I had to restart firefox but when i did it reset all my settings. I tried to increase the zoom through about:config but it does not work anymore. I've tried both ways below-nothing works/changes. Please help, it is extremely difficult to read my toolbar. This should just be a simple setting, ugggh.

Way 1. To zoom the whole browser. This will change more than the tabs.

   Open about:config

   Search for layout.css.devPixelsPerPx

   Change the value Slightly, such as 1 to 1.1 or more. The larger the value is, the bigger the contents are. Be careful, this may zoom in or out too much to see the viewport.

Way 2. To change the font size only of specific parts. This would be harder but safer.

   Open about:config

   Search for toolkit.legacyUserProfileCustomizations.stylesheets and toggle it to true.

   Go to about:profiles

   Find your profile's Root Directory and click Open Directory.

   In your profile directory, create a folder called chrome

   Open the chrome directory, and create a text file named userChrome.css

   Put the text below into the userChrome.css file

Hello We have used about:config / app.update.url to change an internal webserver http://<internalserver/firefox This webserver is an IIS server with the latest Firefox EXE (<strong>Firefox_Setup_138.0.exe) on it. It has directory browsing enable and we have confirmed we can see and download the file OK. However, when we perform Help / About, you see Firefox Checking for updates... but then says Failed to check for updates. What are we doing wrong? Where can I check for errors? Thanks

Please for the love of God, get rid of the asinine Show All when opening about:config. It was a stupid unnecessary change (IF IT AIN'T BROKE DON'T FIX IT) and your users have been bitching about it since it was implemented.

I have to manually change the layout.css.devPixelsPerPx setting evertime I switch from my laptop to an external monitor. What can I do to avoid this every single time?
