Rated 4 out of 5 stars

Good, but the import list doesn't work, don't know why. Allow to edit the list of user agents, but I prefer the list already done, too lazy to search all of them.

Please add a feature to enable at FF startup. Rated 4 out of 5 stars

Very light add-on.

It must be intergrated in Firefox by default cause it's very useful addon

Working good. but every time we need to manually set UA again and again, selected UA gone once we restart or close Firefox. it would be better if it has save option.

Update easier would be nice Rated 4 out of 5 stars

Fairly weak because it isn't updated. You would think it would be easier to update user agents that are available. Copy and paste will work, but this could be done simpler and automated, so it is less of a hassle. Still, probably the best extension of its kind for mozilla browseer. Why aren't there more extensions for User Agents!! This is valuable for proxy and internet tethering.

Good. Getting up to date UA strings is a bit problematic Rated 4 out of 5 stars

This would be really could if the addon could browse useragentstring.com, to load UA strings from there. Because that site has up to date user agent strings.
Or an autoload a constantly updated xml list would be about as good too. But I don't know of any such lists...

The default user agent strings provided are worthless. IE, iPhone and search spiders? Come on, really?
If you want an nice set of browser strings get the xml from here: http://pastebin.com/raw.php?i=CpmdwcVc

Plugin works other wise
