As I watch my MASH for the night...

I really like Firefox because of all the add-ons. I like having some control over the nets! Here's what I use so far...

Bookmarks Duplicate Detector: Alerts me if I try to bookmark something twice.
CuteMenus2: I like to see a symbol associated with menu items--they're faster to identify.
Foxmarks Bookmark Synchronizer: Syncs my bookmarks with Safari, in case I use it for some reason.
Quicknote: A notepad that opens in a sidebar. I use it sometimes.
ScrapBook: You can save web pages (with pics etc), add notes to them, organize them etc. Good for archiving a blog.

Newbies I'm trying:
TimeTracker: Tracks how long you're on the internets. So far tonight: 1 hour and 14 mins.
Easy Comment: To auto fill out blog comments.
Read It Later: To bookmark something you want to read/watch later, but you don't want to permanently bookmark it. This I'm in for.
