The inspiration for this extension came from the A4SEO extension by Dirk Zimmerman (thanks!). Also, thanks to Ian Macfarlane for his suggestions, testing, and other help. The new icon came from a contest I held, the winner was Mateo Byler; check out his Spanish postcards at Postales Shoshan. I’m trying to collect all the Firefox extensions with SEO applications here; if you know of any that aren’t listed, please add them.
For feature requests or bug reports, please email me at [email protected]. SEOpen (the extension discussed on this page) is freely released into the world; I maintain copyrights on all code written by me, but anyone is free to do whatever they want with it. Some versions of SEOpen contain code that was borrowed from other projects, such code is (mostly) commented in the source and may be subject to copyrights or licenses (such as the GPL). If you release work based on this extension, a link back to this page would be greatly appreciated.
