Microsoft's IE9 browser will have tools that control what data is collected about what a user does online.
The tools will let people stop a site they are visiting sharing information about what they do with other sites.
Users will be able to create lists stating that their data will only be shared with sites they want to see it.
The news comes as the US government criticises the computer industry for its slow progress on protecting user privacy.
In a blog post, Microsoft said many people did not realise that when they visit a website what they look for, view or buy there is often shared with other companies without that user's knowledge.
In IE9, Microsoft is planning to introduce what it calls "Tracking Protection Lists" that it says will work like the "Do Not Call" lists that limit who marketing firms can cold call.
Arsenal survived a minor scare to reach the last 16 of the Champions League for the 11th successive season with victory against Partizan Belgrade at The Emirates.
Arsene Wenger knew that three points would assure them of qualification for the knockout phase and they ultimately ran out comfortable winners, although for a spell in the second half against the Serbians, there was the fear that Arsenal's proud record might end.
Arsenal's win was not enough to give them top spot in Group H, and they now face the prospect of running into the real elite of European football when the draw is made on 17 December.
Robin van Persie, Arsenal captain on his first Champions League appearance of the season, put them ahead on the half-hour from the spot after he was fouled by Marko Jovanovic.
Partizan's only moment of serious danger brought an equaliser just after half-time when Cleo's shot took a wicked deflection off Sebastien Squillaci and out of Lukasz Fabianski's reach - leaving Arsenal's fans, albeit briefly, anxiously following events in the game between Shakhtar Donetsk and Braga.
But Theo Walcott's introduction as substitute injected some firepower into Arsenal and some life into subdued supporters inside The Emirates as he made a decisive contribution.
He restored Arsenal's lead with a fine volley after 73 minutes, and another moment of class from Samir Nasri wrapped things up as he scored with a fine low finish four minutes later.
