Perfect, at least for my needs, 5 stars.
+ No interval limitations as with other similar addons.
+ No nonsense features.
+ No nonsense permissions.

I was tempted to give 4 stars due to a distracting little thing: the counter - please make it optional.

Works on the selected URL whether it's in-focus or not. Also, works on that URL upon restart of the browser. Truly "set and forget." Tab Auto Refresh is a well done add-on for Firefox.

THANKS !!!

not working

One of the beter of the breed but NEEDS the ability to ignore refreshing the currently active tab.

Suspecting this add-on can compromise your stored account credentials. Avoid.

Useful add, but slow

It refreshes automatically when the tab is Actively in view. But does nothing once you move to the next tab!!

just well doing it's job. Thank You Alex!

the UI is amateurish and there is no explanation for the weird radio buttons that are actually checkboxes, which seem to break the whole thing by clicking them, but if you don't click around, this thing just works, and allows setting arbiitrary refresh interval, unlike "Tab Reloader (page auto refresh) by James Fray"

Does not currently support domain-based or wildcard-based refresh. This means that if you use a web application that changes the end of the URL (Many do) between logins or while navigating, this plug-in won't work.

Like the simple UI. Add domain support and this will be great.
