I just had a look at what other versoins might be available in the repos, and found the security repo has a lower version:
$ apt-cache madison epiphany-browser epiphany-browser | 3.18.10-0ubuntu1 | http://gb.archive.ubuntu.com/ubuntu xenial-updates/universe amd64 Packages epiphany-browser | 3.18.5-0ubuntu1.1 | http://security.ubuntu.com/ubuntu xenial-security/universe amd64 Packages I just downgraded from 3.18.10-0ubuntu1 to 3.18.5-0ubuntu1.1 - which has fixed the issue. So the problem is introduced somewhere between those two versions. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to epiphany-browser in Ubuntu. https://bugs.launchpad.net/bugs/1668704 Title: Cannot type any input into web pages with epiphany browser after upgrade Status in epiphany-browser package in Ubuntu: Triaged Bug description: I upgraded today from Ubunutu 15.10 to 16.04.2 LTS. Since the upgrade, I can no longer type any entry into any sort of input text box or area on any web page. I only use the epiphany web browser with google.com/voice, google.com/calendar, and i.doit.im. This problem occurs with all three. I also tried the search box at harvard.edu (just to see if the problem might be site specific). When I type, a few letters sometime do appear. I'd say about 1-5% of what I'm typing gets through. I'm not having any problems like this whatsoever with any other web browser or any sort of application.
