Increase in user reports that tabs are duplicating upon startup. User reports on this topic consistently mention that they have a setting enabled to open specific pages upon startup. This may be a duplicate of: crbug.com/732527, however we saw an increase in reports in the past ~10 days.


What happens? (User quotes below):
"I have selected 'Open a certain page or a group of pages'. Each time I open Chrome, it adds to the pages, so if I open Chrome 3 times, the pages will open 3 times."

"I have my settings set to open 3 pages on startup.  Recently I have experienced a problem with Google opening a duplicate set of pages each time I close and start Google.  For example normally when I start Google it opens the 3 pages, but if I close and open Google again I have 6 pages a duplicate of each of the 3.  If I close and start Google a third time I have 9 pages, close and open again and have 12 pages and this continues to duplicate each time I close and open.  I have uninstalled and re-installed Google, worked fine for a couple days then the problem started again."

"keep getting multiple tabs opening, usually about 5 more tabs than I set which are duplicates of the original set, so I end up with 10 tabs. Sometimes it's more 15 or 20 tabs  :-("

"On startup Chrome is opening duplicate sets of my default startup tabs - sometimes 2X, sometimes 3X or more."
