I need to turn off the add-on, reload the page and turn on the add-on again to see the page.

great, but tricky to pinpoint filter setting affects and how they affect each other! youtube is also weird and its impossible to read text overlaying a video unless you highlight it, no matter what filter settings you change.

Excellent add-on!

Just wish clicking icon on panel could switch on/off.

Gets the job done, but the omission of a simple per-site toggle is baffling.

Very functional

Very functional and useful add

in desperate need of updates, totally broken when used with youtube. Still, one of the few add-ons for firefox that can customize text and link colors for individual websites without .css.

Glitches galore.
