FF sticks on blank.html. Any help much appreciated, please

ok, in my case it was because the files under "templates/firefox" were marked as read only. You can try manually clearing the flag on the files or grab the agent update that I just released which automatically clears the read only bit if it is set as it sets up the firefox profile.

Here is how to grab the update: https://sites.google.com/a/webpagetest.o...est-Agents

I also added some extra logic to the extension to make it more resilient in case your issue was different but the behavior was identical so I'm cautiously optimistic that it should work now.
