1. After attaching my USB drive to my main system I received a notice that an update was available for Firefox but the update would not install—how do I get that update?
2. Is it possible to install add-ons to Portable Firefox? When I tried (several times) to add Download Helper I got only error messages.
1. Just download the latest copy from the Firefox Portable website. Due to bur in Firefox itself, running the built-in auto update will break the portable version. Do you have a local copy installed?
2. What error message? Normally, almost all addons work just the way they do with a local install.
Oh and welcome here
