Installation guide for AntiCaptcha plugin for Mozilla Firefox, Tor Browser

Dear users, our extension supports only Firefox version not less than 48. Starting this version Mozilla follows WebExtensions standart. Our plugin is completely written using it and can't be translated into an old Mozzila format. That's why on elder versions of Firefox AntiCaptcha extension either won't start installation or will show a corruption error.

This is the same reason why it doesn't work with browsers Pale Moon and Seamonkey. Simply put, they refused to implement a new standart to have a support of old extensions and their special features. But with TorBrowser our extension works quite well and we test new releases with it.
