Starting a few weeks ago, Chrome has started randomly opening new blank tabs. It happens mostly when I open an application from the dash, but not every time. I've tried removing Chrome and re-installing and clearing all my cookies from Chrome. I haven't figured out any other patterns to this, but it's pretty annoying. Has anyone else seen this and might know a fix?
It may be your online accounts. Sometimes Ubuntu loses access to the Google (or another) account and needs re-authorization.
Go to System Settings... from the Gear/Power icon on the top right corner.
click on Online Accounts under "personal" and press the Grant Access button for the accounts that are turned off.
Let me know if it works, by comments below.
Hope this helps
