First of all, the original attempt left me with an Ad block plus in my FF 3 0 3 tools. It seems to run, and shows several of these...
The Great Circle :: Aviation Pilot Supplies & Flight Training
They was just a string of code when I pasted it in.!
They are shown as enabled. One with many hits. There seems to be so little to go on as to what happens next.
Re reading, I assumed I should have created the directory in FF shown in the blog. Got nowhere with that. As follows.
I have to just be missing the point somewhere.
Well, the download that i get is ..... Refusing to be pasted in here! Just don't know why. Download_plus (lots of stuff then ).xpi
I was told to put it in Mozilla -- Extensions -- and a file that was named from their site, which was a long string. This won't copy and paste either but is similar to the other folder names in Extensions.
it doesn't have { } at the ends like the others.
Anyway, if I do this, it unpacks, but then asks for code word and subscriptions etc. No concept of where this codeword comes from and had assumed it was free.
