(I searched but couldn't find any thread dedicated to Firefox addons.) Currently I use FireFTP, NoScript and PopUpMaster. FireFTP looks very nice and user-friendly, but every time I try it, all I get is: -- Unable to make a data connection. Please try again. -- 501 Syntax error in parameters. : // I can't seem to get around it. So now I use CyberDuck. NoScript seems to work wonders. It stops scripts all over the place. And I like it's white-list idea. It gives me a (false?) sense of security. I tried AdBlock Plus, but I couldn't see that it made any difference. I visited a few ad-heavy pages, and they looked the same before and after. Still, since so many people praise it, I suppose I'm missing something. I'm not sure what PopUpMaster actually does, other than giving me a little icon that I can click on. I was hoping to find a way to avoid popups & popunders. While Firefox seems to suppress most of those all by itself, there are still websites that manage to create popups/popunders. Anyhoo, I just wanted to find out which addons people tend to prefer and why.
