Opera complaint takes aim at Microsoft’s Edge tactics

Opera complaint has landed in Brazil, targeting Microsoft for steering Windows users into sticking with Edge and Bing. Opera says these “manipulative design tactics” limit fair competition and stop people from freely picking their browser.

Opera complaint filed in Brazil over Microsoft tactics

Opera complaint argues that Microsoft blocks rivals at every step. “First, browsers like Opera are locked out of important preinstallation opportunities. And then Microsoft frustrates users’ ability to download and use alternative browsers,” said Aaron McParlan, Opera’s general counsel.

The filing highlights Microsoft’s repeated moves to bypass a user’s default choice. Outlook, Teams, Search, and Widgets all open links in Edge instead of the selected browser. Opera complaint also points to popups and banners in Edge that warn people against installing competitors.

Why Brazil is central to the Opera complaint

Brazil is not just another market. Opera complaint is especially relevant here, since Opera ranks as the country’s third most popular browser. Millions of users pick it every day, despite Microsoft’s push for Edge. By filing in Brazil, Opera hopes the case sparks stronger rules and inspires other regulators to follow.

Microsoft’s track record of pushing Edge

Microsoft has used aggressive tricks for years. It has inserted malware‑like popups, altered Chrome download pages, and even tested a fake Google‑style interface inside Bing. That test mimicked Google’s search bar and doodle, tricking some users until Microsoft pulled it after criticism. Opera complaint ties these tactics together, arguing they show a pattern of manipulation.

Opera’s remedies and global strategy

Opera complaint sets out clear demands. Opera wants PC makers allowed to preload other browsers, an end to blocks on downloads, and removal of design patterns that steer users toward Edge. It also claims Microsoft ties Windows rebates to S Mode requirements, another practice it says restricts choice.

This campaign goes beyond Brazil. Opera has appealed in Europe after the EU refused to label Edge as a “gatekeeper” under the Digital Markets Act. Microsoft escaped that tag, yet it still had to make changes to Windows in Europe. Even so, Opera complaint stresses those fixes fall short.

The fight over browsers is far from over

Opera complaint is not new it echoes the 2007 case that led to the EU’s browser ballot. That rule forced Microsoft to give users real choice, but the company was fined $730 million in 2013 for breaking it. Now Opera is betting fresh pressure from Brazil and abroad will finally push Microsoft to back down. The browser wars are alive, and the battlefield keeps shifting.
