It sounds like your keyboard Ctrl key is stuck down, which will cause both the tabs problem and the zoom in/out problem.
Please tap the Ctrl keys on your keyboard several times in case one is stuck. If that hasn't solved the issue then please also try briefly unplugging the keyboard to see if your mouse then works properly in Chrome. ** Changed in: chromium-browser (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883718 Title: zoom in/out problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1883718/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
