Without this and TabMixPlus, i may well ditch Fx :( Rated 5 out of 5 stars
This and TMP have been my staple add-ons since i left Opera for Fx when Opera decided to ditch you know... features. I sincerely hope something like this can be done in Fx 57 because Fx native Bookmark management is unusable IMO (maybe it'll be better in future versions?). I actually donated a trivial amount to this one.
Enjoy the extra time you get. Curious - will YOU keep using Fx?
Thank you for this and your other terrific add-ons.
