Does what it says: toggles CSS on or off. Makes some websites with a grey font much nicer to read.

Finally a plugin to restore some pre-quantum functionality.
Thank you!

I find it very useful, for some reason, however, Avast thinks it is dangerous and recommends to remove it.

A solution to relapse old RightToClick addon. Works perfect.

Works as advertised, although the toolbar icon is nearly invisible with dark theme.

Just what I was looking for, disappointed that it does not appear to disable CSS.

Edit - has a compatibility issue with Quickjava Legacy addon - even when QuickJava is disabled. I uninstalled Quickjava and CSS Toggler works perfectly ! :D
