1)When I installed FireFox 4.0 it disabled the .Net Framework Assistant, if I remember correctly was version 1.2. 2)Downloaded and installed Microsoft .Net Framework 3.5 SP1 and installed. FireFox did not recognize this version of .Net. I then installed a Microsoft .Net patch to make 3.5 SP1 compatible with FireFox. After this FireFox 4.0 does enable .Net Framework but the version reported is 0.0.0 My system has .Net Framework 3.5 SP1 and .Net Framework 4 Client. How do I enable FireFox to use and report version 3.5 or version 4.0? Thanks
