When I try to install an add-on I keep getting this message. This happens in both vsn 3.6.13 and 4.0.10.

For some reason the add-on keeps insisting I have vsn 3.0. This is not limited to a single add-on. Most show a symbol of 3.0 with a red mark out over it.

You need to reset your user agent string (identifies the version of Firefox), yours is showing you as having Firefox 3.0, it appears to have been altered by the VRE toolbar. For details of how to reset the user agent see https://support.mozilla.com/kb/Websites+or+add-ons+incorrectly+report+incompatible+browser
