Possibly a solution here. I had same problem. Two "about:blank" pages was opened on startup. Sometimes in two distinct windows, sometimes in one window but in two tabs. In my case, Chromium was not in "Startup applications", and "Continue running background apps when Chromium is closed" made no difference. Problem stopped when I removed my Google account from my "Online accounts" in Ubuntu settings !
P.S: My Ubuntu is in french, so I'm not sure about names in english. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1176903 Title: Chromium browser window opens on startup even though I never configured this Status in “chromium-browser” package in Ubuntu: New Bug description: When I start Xubuntu 13.04, a Chromium window opens after I log in to my session. I have never configured Chromium to open a browser window automatically. This happened even back with 12.10, before I upgraded the instance to 13.04. Note that this is not the same as #1175601. With the other bug report, the problem is two background instances of Chromium are running at the same time. With this report, the problem is not the background instances but that the browser window opens without me having configured it to do so. What should happen is, by default, the Chromium browser window does not open until I manually open it. I also have a 13.04 Xubuntu instance that I built from scratch. It also has chromium-browser installed, same version as on the machine with this problem. Not only does it not show a Chromium background process in the menu bar on the top right, running "ps xfwww" does not show any evidence of a Chromium background process running, so I am seeing inconsistent behaviors here. (Not sure if that informs this bug; I'd be happy to open a different bug report if appropriate.)
