When I want to install themes from FF Add-ons almost in all themes it says: "Not available for Firefox 2.0.0.9 - but my FF is 3.6.10. I tried to find solution in faq the closest to it was to find update.xmls and delete them but I did not find them on my computer... so why "thinks" the add-ons that my FF version is 2.0.0.9?

You need to reset your user agent string (identifies the version of Firefox you are using). For details of how to do that see websites or add-ons incorrectly report incompatible browser.
