Are there any compatibility issues between Firefox 6-beta and Norton internet security?

I received a warning before installing it that Firefox 6-beta is incompatible with the Norton toolbar - does this imply any deeper compatibility problems with Norton?

That "test" only implies a number is incorrect in the add-on, nothing more should be read into that message.

Norton, and many other security software vendors, don't usually support pre-release Beta version web browsers. Firefox only checks the maxVersion specified in the install.rdf file for the extension that is installed in Firefox, which is a very minor point as far as "compatibility" goes, and that is "set" by the developer of the add-on. The burden for true compatibility is on the developer.
