I have Firefox 3.6.1.7 installed on my XP computer, and it seems to work fine with JAWS 9. But before I consider updating to Firefox 4.0, I installed the portable version of Firefox 4.0 to see how well it works with JAWS 9. Everything seems to work satisfactorally except for the Add-Ons submenu under Tools. I was able to successfully install the Navigational Sounds, Plain Old Favorites and Webvisum add-ons after I launched Firefox 4 portable for the first time. However, when I try to access the Add-Ons submenu under Tools, a page called Add-Ons Manager comes up, but there is no list box of installed add-ons (extensions) or any other menu options. Obviously, if the add-ons work, they must be listed somewhere, but they don't show up on the Add-Ons submenu like they do in the full version of Firefox 3.6. Has anyone else encountered this issue with Firefox 4? Or is there a compatibility problem with JAWS 9? Or are the Add-ons perhaps listed somewhere else where they can be accessed? Thanks. Gerald
