How to disable dark theme on webpages in Firefox?

I switched to a dark theme (Dolorean Dark). I like it and I think--it is better for eyes. However I have problems in some web pages. Most pages are intended to be shown on white background. On dark theme form controls have black background and mostly the font is also black, so the content of forms are invisible. I would like to use white theme on web pages in Firefox.

The best solution to tell Firefox that it should use the light theme instead of the dark is by specifying the GTK_THEME variable prior to launching.

So, 4 ways you get for doing this..

1- from terminal you can do:

GTK_THEME=Adwaita:light firefox

2- if you hate the terminal and wanna close it once firefox works:

GTK_THEME=Adwaita:light firefox &

3- from firefox about:config you can set the following setting to false:

browser.display.use_system_colors

WON'T WORK FOR localhost SITES! so if you are a web developer/designer it won't work out that well for you.

4- if you want this to be the defualt behavior:

Just add two lines to the Firefox launcher script located at /usr/lib/firefox/firefox.sh

in the terminal type down:

sudo gedit /usr/lib/firefox/firefox.sh

look at the beginning of the script for this:

MOZ_LIBDIR=/usr/lib/firefox

MOZ_APP_LAUNCHER=`which $0`

MOZ_APP_NAME=firefox



export MOZ_APP_LAUNCHER

and change it to this:

MOZ_LIBDIR=/usr/lib/firefox

MOZ_APP_LAUNCHER=`which $0`

MOZ_APP_NAME=firefox

GTK_THEME=Adwaita:light



export MOZ_APP_LAUNCHER

export GTK_THEME

Finally, restart Firefox.

Hope this helps.
