This is real wonderful extensions. I love it

works like a charm

This is very nice extension, I am very very love it. Thank you so much, Bernard.

This is one of the most useful addons for Firefox!

Still, without any attempt to decry Bernard's good work, I do need to say it's a pity that addons like these are necessary at all, because web page designers do not think of any thing else besides shiny white pages with black writings. This might look good when you're sitting inside a well illuminated office, but that's not where everyone else is reading their pages.
