needs the ability to keep the theme applied after i quit Firefox

This could be really handy, but currently, it isn't practical because each time you restart your browser, you have to either set it all up again, or have saved it to your desktop and reload it again. If this gets updated to save the themes you create to be applied simply by selecting them, I would give it 4 or 5 stars. As it is, I am disabling.

That's what I need. Thank you very much~!
In addition, it would be better if the search box in the sidebar could also be adjusted.

Working GREAT! Missing one star because a few selectors are missing. But thank you very much for the extension!

great work :) going testing
