Recently (starting about 2 weeks ago), when I click on something (usually a link) in Chrome (on Windows 7), there is probably a 1-5% chance (a couple of times per day) Chrome will open this page on a new tab:
I didn't install any new extension, I doubt it is caused by extensions.
Another weird behaviour (that may or may not be related):
Starting about a month ago, is when I click a link with target=_blank, it is sometimes opening it in the same tab.
Anyone has any idea what this could be?
After a full week of enabling/disabling extensions, I finally found that it was caused by an extension called Video Grabber (not in Chrome Web Store anymore) that I might have installed years ago.
