Firefox is undoubtedly a good product. It's small, standard compliant, looks native on all platforms and works reasonably fast. It has a strength that is also a weakness: very minimalistic feature set. There are thousands of extensions out there that supplement the core feature set making the offer as a whole really great.

But adding more and more extensions becomes a pain in and of itself. Setting up large number of extensions on each and every machine that you own gets tedious really fast. That's why it's best if you can keep the number of extensions as low as possible.

Old habits die hard but it doesn't hurt to occasionally check if some of the extensions you've been using have been superseded by a newer variant or if a few have been consolidated into one. In my case, a few things happened recently:

• AdBlock Plus has superseded AdBlock
• IE Tab has generally replaced IE View
• TabMix Plus replaced Tabbrowser preferences and Session Saver; I am particularly happy about exchanging these two extension for one - Session Saver has The Most Horrible UI Ever Conceded ^TM and while Tabbrowser preferences worked fine it tended to forget a few of its settings; TabMix Plus replaces both and has all the features you could ever imagine to ask for

I think I have reduced the number of extension I use to about 4-5 and I plan to keep it this way.
