In recent months, Google has raced to settle a backlog of lawsuits ahead of major antitrust showdowns with the Justice Department later this year.

On Tuesday, the company resolved its fourth case in four months, agreeing to delete billions of data records it compiled about millions of Chrome browser users, according to a legal filing. The suit, Chasom Brown, et al. v. Google, said the company had misled users by tracking their online activity in Chrome’s “Incognito” mode, which they believed would be private.
