Why is this a plus? Few people would use all of these gadgets, and if they don't, then it's just so much bloatware. You really don't want a bunch of plugins you don't intend to use.
Exactly. That's a major feature of Firefox IMO. You only have to install what you want it to do. There are a lot of discussions on the Mozilla forums about feature creep, and I think the FF team has done a pretty good job with it. Personally, I'd have probably gone with an even more streamlined base install than they have, but overall, it's not bad at all.
Extensions rock. Wish more software were designed like that.
