User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1)
Build Identifier: Gecko/2008032620 Firefox/3.0b5

When you run the install of FF3b5 on machine which is already having FF20(latest build) and lot of extensions installed on FF20, the installation process gives a list of extensions for which updates are available now ( assume some of the extensions installed on FF20 are outdated). 

Choose to upgrade these extensions along with FF3b5 installation process. The installation process shows that the extensions are also upgraded successfuly. But when the FF3b5 browser launches, these extensions are not displayed in the browser.

Reproducible: Always

Steps to Reproduce:
1. Have FF20 installed on machine with some extensions for which there is an updated version available.
2. Run the installation of FF3b5, the installation porcess will list down the extensions which are not compatible and give an option to search for upgrades for these extensions.
3. Go ahead search for upgrades for these outdates extensions and try to update them as well in parallel to FF3b5 installtion.
4. Launch ff3b5 browser after the installtion process is over.
Actual Results:  
The upgraded extensions are not visible/displayed in FF3b5 (FF3b5 compatible versions for these extension are available as getting installed separately).

Expected Results:  
All the extensions which got upgraded and for which FF3 compatible verions are avaiable should be displayed.

Updating of these extensions goes smoothly via tools->Add-ons->Find Updtes
