The add-ons were blocked at the request of Russia’s federal censorship agency, Roskomnadzor — the Federal Service for Supervision of Communications, Information Technology, and Mass Media — according to a statement by Mozilla to The Intercept.
“Following recent regulatory changes in Russia, we received persistent requests from Roskomnadzor demanding that five add-ons be removed from the Mozilla add-on store,” a Mozilla spokesperson told The Intercept in response to a request for comment. “After careful consideration, we’ve temporarily restricted their availability within Russia. Recognizing the implications of these actions, we are closely evaluating our next steps while keeping in mind our local community.”
