When I click on an external link and Google Chrome is not running yet, Chrome will launch but will not open the linked page. Instead, it starts at my last opened tab (which is the behaviour I expect), but the clicked link should also open in another tab.
When I click the link a second time, it will open correctly in a new tab.
Why is this?
For clarification, it's about macOS. Furthermore, I found it behaves different to how I described above. The link is opened in a new window the first time, instead of a new tab in the existing window. The problem is, that it does not come to the front, so the old window from my last session in Google Chrome is in the front. You don't notice the new window behind the old one unless you use mission control to see there is a second window.
Since this question got a lot of attention I finally accepted the top voted answer, though this wasn't my problem in the first place at all. I can see that there are two problems here:
When there is a pending Chrome update, Chrome does not open the external link at all, just opens another window with the default start screen. (Bug)
When Chrome is up to date, external links are opened but this time still a new window in the background and not as a new tab when restoring the last session. (bad design)
Hope this should be clear now :)
