Facebook has announced that it will be making the site available in Arabic and Hebrew.
It is already available in 40 languages and development is underway for a further 60.
Ghassan Haddad, leader on the translation process for the site, said on the official Facebook blog: "Supporting different languages on the web always entails many technical, cultural and linguistic issues, but right-to-left languages present extra challenges."
Facebook, which has an estimated 175 million users, has said its "work isn't done yet".
Haddad said: "Our goal is to make Facebook available in every language across the world."
The announcement that could secure Facebook's further domination in this market comes in a week that social networking sites were branded as more popular than email by a report from Nielsen Online. The report also stated that social networking sites were now visited by over two-thirds of the global online population.
