Opera files competition complaint against Microsoft over Edge browser tactics
Opera has filed a formal complaint with Brazil’s competition authority, accusing Microsoft of using manipulative design tactics to promote its Edge browser on Windows. The company alleges Microsoft actively undermines default browser choices by opening links and PDFs in Edge, even when other browsers are selected as default. Opera also claims Microsoft restricts pre-installation opportunities for alternative browsers and uses obtrusive messages to dissuade users from switching.
The complaint spotlights global concerns about Microsoft’s practices and could prompt regulatory scrutiny beyond Brazil.
A ruling in Opera’s favor could force Microsoft to change its Windows browser practices worldwide, impacting competition in the browser market.
