I've just uploaded SFE 0.5 to Mozilla Addons. Grab it here now or via the update manager when it will be approved.

Changelog:

• Updated for Firefox 3.
• Fixed popup position bug (thanks to Steven for reporting this).

Simpy Dashboard Widget 0.1

• First release.
• Requires OS X 10.4.3+.
• Displays your latest links.
• Lets you search by tag or tags (separated by comma).
• Attempts to make it use all links rather than a user's links were unsuccessful. This is because the RSS feed for all user's links is huge and loading and parsing it took too much time.
• Grab it here.

Simpy Firefox Extension 0.4

• Changed the name to SFE. In the Linux tradition it means SFE Firefox Extension and not Simpy Firefox Extension as you might think. The name change was done since Simpy implied it being official, which is not.
• Updated for Firefox 3 beta.
• Added the possibility to use a popup when adding bookmarks. Warning: popup does not have group info.
• Some code cleanup.
• Grab it here or, when it's approved, here.
