This is a couple of trivial but useful extensions for mozilla firefox.
Switches the "Override the colours specified by the page with your selections above" in the "Language and Appearance - > Colours" pane between "none" and "always".
Switches the "Allow pages to choose their own fonts, instead of your selections above" in the "Language and Appearance - > Fonts and Colours -> Advanced" pane between "on" and "off".
Unfortunately because mozilla are a bunch of cunts there's no way to create an installable 'xpi' without creating an account on their site and getting them to sign it.
If you're so inclined, have at it.
Due to the above i've included the signed packages I use in "dist/". They can be installed by going to "about:addons" and selecting "Install Add-on from File..." menu item from the "anus menu" over on the right hand side.
For now, just get it from git:
