works on windows 7, or windows 8/10 with a css

maybe this worked in some previous firefox ver, but it just makes everything blindingly white now. (firefox 96)

no just no

Doesn't actually add any transparency

This just turns the title bar white for me. It itsn't transparent

No transparency, only bright white background..

Does not work. No transparency

It's not transparent. Sorry, doesn't work that way.

Really awesome. I love win7 transparent windows, with this theme I can apply it to firefox as well. Love it!

This is awesome.Thank you!

Sometimes I don't want a color or background, so this is great.

It works for about a day and then everything the theme changes turns white. I have to uninstall and reinstall every time it happens. But it's a small price to pay to be able to have a transparent theme.
