Useful Extensions for:
Thunderbird:
- Nostalgy, for Mail Act-On Act-On -like functionality (less polish, but with autocompletion and no dependency on rules).
- GMailUI – some Gmail functionality, grafted on
- Quicktext – templating
- Remember Mismatched Domains – useful for SSL access
- Remove Duplicate Messages
Firefox:
- Screengrab lets you save a full-length web page “screenshot” to a file.
- Tamper Data, a HTTP manipulation/testing tool with page element download timelines.
- Fission, a Safari -like progress bar.
- del.icio.us extension
- Backpack pages – adds Backpack to your toolbar.
- Aardvark – interactive HTML inspection
- Scrapbook – lets you save and annotate web pages, with full text search.
