Rated 5 out of 5 stars
GREAT add-on and compatible with FF4 no less.
It's everything i have searched for.
I have used "multirow bookmarks" for a long time untill it is no longer supported by FF4 (unless you have to workarround with scripts and wot not!)
And then i found this great tool that not only add multiple rows of bookmarks like Multirow bookmarks but also has the ability to hide/unhide or customize the size of the bookmarks with or without text ..
I have had no issues as of yet with this addon and its doing exactly wot i expect to do.
REALY RECOMMENDED poeple
So its fair to say this deserves a 5/5 star rating..
