This is already fixed in the current version of Firefox which will be available as a security update before Ubuntu 17.10 is released.
There are a few workarounds for now to get the current version of Firefox in Ubuntu 17.10 if you really need it. One is to manually enable the zesty-security archive. Another is to use the firefox-next PPA to try out the next (beta) version of Firefox. ** Changed in: firefox (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1713347 Title: Firefox highligts textarea on mouse click (focus) in orange, it distracts user To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1713347/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
