There's a translation service that takes the URL to be translated as part of the path, as follows:
http://ria.ru/some-article
http://translate.yandex.net/tr-url/ru-de.de/ria.ru/some-article
See how the source URL ends up at the end of the translation URL? Note the protocol part has to be omitted; if not, this could be mapped using a Firefox Quick Search.
Now I'd like to be able to do the translation with ease (say, hit F8). Yes, I could start doing the Add-On tutorial, and that would certainly provide me the means solve the problem. But there might be an easier way.
There's a similar question here.
