Packt reports that Gab's Dissenter browser extension was removed from Mozilla's Firefox add-ons on April 10th (people already using it can continue to do so), and was booted from Google's Chrome browser the next day. Gab pitches itself as an anti-censorship social media platform that only prohibits speech that is illegal. Their Dissenter browser extension and associated website allow people to share comments about any webpage, giving users the ability to share comments on articles, videos, etc., regardless of whether or not the website hosting the content has a comments section. Mozilla's rationale for the ban was that Dissenter was being used to promote violence, hate speech, and discrimination, but they failed to show any examples to bolster that claim. Gab plans to develop their own browser in response.
