Mozilla is rapidly becoming kickass. Under Linux their mail client is almost the best thing going (offline mode, SSL IMAP, POP, SMTP) and now plugins to fill in the missing gaps are arriving. Tips and tricks below.
PGP/GPG Plugin
- Freaking finally!
Roaming Bookmark Server
- Miss the old days of roaming with Netscape 4? Me too ... Bookie brings part of that back, store your bookmarks on a cetral server and allow all your copies of Mozilla to use that.
News Alert
- Bring breaking news to your desktop. Stop having to check sites to see if there's something you want to know. Yay for Mozilla!
!CaScadeS -- CSS Editor
- Edit inline CSS inside Mozilla.
Checky - Sidebar Validator
- Sidebar plugin to most online validation services (RDF, CSS, XHTML etc).
Side Bars
Devedge has CSS2 and HTML 4.01 side bars. really nice.
There are some other good side bars here (CNN Headlines, advanced google search, search me etc)
