Does exactly what it is described to do (Version 27.0t24.3.0+ Review). Bewertet mit 5 von 5 Sternen

Does exactly what the description says.
On another note, I also do know that extensions like this one can cause some updating problems (depending on the system you're using) for some downloadable programs (like iTunes, Flash, Java). However, this can be fixed simply by disabling this extension temporarily if a 32-bit program doesn't like your 64-bit system. Overall, this is a good extension as this extension does what it is supposed to do.

If you would like more ideas/etc for your extension. Please locate my e-mail on my profile and I will get back to you as soon as I can.

Update:
Very nice developer who keeps this extension up-to-date with browser updates that come along. For example, Firefox 27.01 was updated to Firefox 28 (The developer keeps this extension up-to-date with change). Very well done as this is difficult to do!

This add-on does exactly as the description says. Developer has done a good job keeping up with the fast development cycle. Unfortunate more are not using this add-on as it would become more powerful against fingerprinting with ubiquity. Received my lowest score to date with Panopticlick using this add-on and NoScript.

Not yet for 8 Bewertet mit 4 von 5 Sternen

The version for Firefox 8.0 that has yet to be approved does not work. But the idea is very good. So that's why I rated it a 4 out of 5.

Does as promised. Bewertet mit 4 von 5 Sternen

Works as advertised, simply and cleanly changing the operating system reported by your browser. However, if you're looking for anonymity (not sure why else you would use it), this has pretty minimal effect. This is not the fault of the plugin, it's just that the OS doesn't actually convey all that much identifying info since there aren't all that many to choose from. Things like plugins and font lists are far more informative. Also, changing the OS reported by your browser makes a lot of download pages (including Firefox's) more difficult to use because they'll automatically present you with links to the OS they think you're using.
