Well done! Rated 5 out of 5 stars
I run a zillion add-ons and at the moment I am doing an agonizing review and migration of my add-ons to another browser one-by-one and redoing each of the settings manually. Since I run a zillion add-ons this has taken days. Needless to say, I am constantly using the add-on manager in 2 browsers simultaneously and after I stumbled into this add-on I gave it a try. There really is a difference! I also agree with the other review that it should be included but I would put zero faith in Mozilla these days. Each version of Failfox gets worse than the one before it so don't expect any improvements from them. It is the community that will keep things working.
**edit** You are correct. It does deserve the 5th star. Usually I only give the 5th for the most radical changes- but since I probably will be using the manager more than most I am boosting it up a notch.
As far as the migration I normally use FEBE/OPIE/CLEO but I really needed to do it manually for debugging a longstanding issue. The silver lining is I get to do a top-down review of everything and it meant ( for the millionth time) adding a few, subtracting a few, confirming most of what I already had... However, this is insanely time-consuming the improved interface will especially benefit me during this process. I also run what was one of the leading collections on here( at the moment it is hidden for maintenance and I later on I will delete it) but I will add it and I will unhide it shortly. When I delete my collection I will have my own master website up and I will be promoting tech that actually works. Your add-on is almost certainly going to be included. Good job!
Thanks for trying out my addon. Is there any issue for which you rated it 4 stars?
Did you know that you can use Firefox Sync to get your addons installed on your other installation?
