Since most of the cool features that exist as firefox extensions seem to only get passed around by word of mouth, I thought I'd see if anyone else here has anything interesting that I'm missing. So far, I've got these installed: ieview-still need this one every so often... Dictionary Search-Nice feature DuplicateTab-duplicates current tab with history ImageZoom-I use this one all the time! TargetAlert-Much improved in the latest version. Appends icons to links to tell you if they open in a new window, or if they're an email address, word doc, etc. New version has an option to only display these on mouse hover. BugMeNot-Very convenient way to bypass registration on many sites. Rather than visiting the website, just right click in a login field. TinyURL Creator-Another shortcut to a useful service. Create a tinyURL with a right click on any page. miniT-Simple tab rearranger that I use all the time. AniDisable-Makes animated images stay still. I don't like getting distracted by too many moving images on webpages, and this was the last annoyance left after flash! Flashblock-Replaces all flash content with a play button. Sage-An embedded RSS reader. Could use some more features, but it's a good start!
