CountdownClock

Will not display ... author seems to have left Rated 4 out of 5 stars

This add-on is written to display on Firefox's status bar, which is no longer supported on FF 29. The author seems to have moved on as his domain now brings up a generic page from Gandi.net. I recommend looking for an alternative add-on.

This user has a previous review of this add-on.

N0HR Propfire

FF 8.0 Rated 4 out of 5 stars

It seems to work fine under FF 8.0. You may have to manually inform FF that it works by going to the add-ons page, clicking the Compatibility button for Propfire and choosing the "This add-on still works" option.

This review is for a previous version of the add-on (0.76.0.1-signed). 

CountdownClock

Update for Firefox 4 Rated 4 out of 5 stars

I've come to depend on this addon for shuttle missions, important birthdays, etc. No other countdown addon is as versatile as CountDownClock. But it does not seem to work with Firefox 4. Please update.
