Waardering 5 van 5 sterren

Thanks for answering,

Do you have in your plans to make it to work with FF 57?

Deze beoordeling betreft een eerdere versie van de add-on (0.5.5). 

If the WebExtensions API doesn't support it, nothing I can do.

As long as FF keeps support for UserChrome.css, you can still manually add the CSS (just stick the mosaic in the same folder as userchrome.css).

Last time I checked styling menuitems/buttons wasn't allowed with WebExtensions :(
