I just switched my browser from K-Meleon to Firefox 3.0. From searching other threads here, I notice that many people use FF w/ EXTENSIONS. I've also heard that adding too many might slow down the browser and increase the memory usage. I've only added 2 extensions (FireFTP and RoboForm) thus far because those are the only 2 I really need. I'm using Ad-Muncher w/ KIS 8 for my ad blocking and security needs. Is it recommended to use Firefox 3 just basically set to default or are any particular extensions recommended for SAFETY and better optimization? Also besides FasterFox (it makes FF not play well with KIS)....should I do any "tweaking" (ie using FireTune) or just leave it at the DEFAULT settings? Any help and suggestions by you long-time FF users is appreciated. Thanks.
