a must have Rated 5 out of 5 stars
I use firefox 2 since 3 has what i consider a slow and non productive bookmark system. plus its adds a lot of bloatware.
So this is indespenable for v2 firefox. I do a search for a bookmark i want. then i can instantly find it, just in case i didn't dump it to a folder name that makes sense, or bookmarked in haste.
