I use pretty much every browser. I switch between them depending on mood, system I am on, phase of the moon, etc. But there are some essential “bookmarklets” that I always want to use/set up.
There are a few things I wish I could tweak though. Like with Yammer, the ability to choose a group before it hits the page. Also with the Yammer bookmarklet there is about a 50/50 chance the URL/title wont come through so you have to do it manually.
With the Gmail This one, on Safari, it opens in a tab instead of a popup, and loading Gmail is kind of slow (IMHO) when you want to just write a mail from out of no where.
What bookmarklets do you use? Are you a share-a-holic?
