I'm happy with IE7 for my main browser, but also use FF3 to see how things work.
I've just found that there seem to be some bugs with Microsoft's Virtual Earth for visitors using FF3. Depending on the VE version in use some map 'mashups' work but some completely fail.
Thinking it was down to the website's mashup code I thought I would check
maps.live.com with FF3 to see if that works and was surprised to find that it doesn't!
MS redirects the visitor to a 'browsernotsupported' page which only displays this message:
"
To use this feature, open Live Search in Windows Internet Explorer version 6 or 7.
For more information, and to download the latest version, visit the Microsoft Internet Explorer website (http:// www.microsoft.com /windows/ie/downloads/default.mspx)."
Not very friendly or professional! I'm not sure if the problem is with FF or MS or a bit of both.
Searching around I can see some posts about FF3/VE problems but not too much helpful stuff. Searching for the exact MS phrase above doesn't return many results either which surprised me.
I thought I would post here to see if anyone stumbles across it and can add some useful comments.
