Just wanted to let people know how I got the Google Voice plugin to work so that I could use the "Call Phone" feature from within gmail. This is *not* elegant but it's the only way I could figure it out because the target computer is behind some nasty firewalls (and the Google Voice installer isn't allowed to call home to download its files).
1. Install the Google Voice plugin on your home computer.
2. Locate the Google Voice and Video Accelerator plugins in FF using about:plugins.
3. Copy those to your Firefox Portable plugins directory on the flash drive.
4. Locate the "Google Talk Plugin" folder on your hard drive and copy it to the flash drive (doesn't matter where).
When you want to use Google Voice through Firefox Portable, run the exe in the Google Talk Plugin first, then start FFP and go to gmail. Note that once you exit gmail, it will stop the exe, so you'll have to run it again manually if needed.
Anyone have any suggestions to automate this?
