Modifications to Existing javascript extension

I would like the following modications done to the existing javascript extension for Firefox: [login to view URL] [login to view URL] 1. Create a revised version (Version A) of the linkgopher software, but have it default to 'Extract Links by Filter', and use the default search term, '/user/'. I don't need the opportunity to edit the '/user/' value, I just want it to run with that value as soon as I press the extension icon. 2. Create a revised version (Version B) of the linkgopher software, but have it default to 'Extract Links by Filter', and use the default search term, '/WorldofTanks/'. I don't need the opportunity to edit the '/WorldofTanks/' value, I just want it to run with that value as soon as I press the extension icon. Also, when it runs, I need it to only display unique links. For example (and using the line numbers added): -2 Links -1 0 [login to view URL] 1 [login to view URL] 2 [login to view URL] 3 [login to view URL] 4 [login to view URL] 5 [login to view URL] 6 [login to view URL] 7 [login to view URL] 8 [login to view URL] 9 [login to view URL] 10 11 Domains 12 13 [login to view URL] I only want lines 1, 2,and 7 to appear in the results. I want to eliminate the 'Links' header section and the default sub name (lines -2, -1, and 0) I also want to elmintate the 'Domains' section/data (lines 10-13) 3. I will want to have three separate gopherlinks on my brownser, the original one, version A, and version B, so I assume they'll need different names in order to be installed. 4. Needs to run on Firefox.
