Firefox addons or plugin

1. Xmarks (formally Foxmarks) - forget the rest, if I have this one only, I will be still a happy bunny! The bookmarks sync 'par excellence', Xmarks never lest me down, especially for a net addict like me who likes to carry his set of preferred bookmarks accross cyberspace. The extensions seameslly synch my toolbar bookmarks accross my Ffox versions (on my laptop, Flash drive, desktop and netbook)

2. AdBlock Plus - The second add-on which is has constantly proven itself to be a must. I had ads: I have limited time to surf the net these days and I can't staff obstrutive banners getting in the way of web reading.

3. Web of Trust - With the constant paraonoia about net security, there is some kind of warm and fuzzy feeeling knowing that WOT can warn you before you click on a dangerous web page with hidden and malicious intent.

4. LassPass: a recent discovery but an essential piece of kit who consumate web surfer like me. The knowledge that I can access all my secured web pages without typing the relevant security details makes me feel good (somehow!).
