Suddenly all the browsers begin to open all links in a new tab. Even when the link is deliberately intended to leave me at the same page (say, uncollapsing some text).
I tried Safari, Chrome and Firefox, the behaviour is the same. I also tried to close (and even to kill) and then reopen every single browser, but still no luck. After reboot this behaviour disappears until the next time. But I'd like to avoid rebooting. I cannot reliably reproduce this issue, but it occurs from time to time and annoys a lot.
Any clue on how to cure this? P.S I use MacOS 10.13.3
