cmd-\ to fill password fields in Chrome stopped working a few weeks ago on both my iMac and MacBook Pro.
I'm using 1Password 5.3 and Chrome 46.
1Password Version: 5.3
Extension Version: 126.96.36.199
OS Version: OS X 10.10.4
Sync Type: iCloud
There was a bug relating to WebSockets that creeped into the developer build of Google Chrome. I believe there is now a fix that should make it into the dev build soon. Just as an FYI, the issue isn't present in the stable or even the beta version of Chrome - it's been isolated to the dev branch. You should find it works again soon (as long as you keep Chrome updated). Let us know if it continues
I thought Chrome 46 was the newest stable version.
At the moment Chrome 44 is stable, 45 is beta and 46 is dev. If you go to Chrome > About Google Chrome and check the version number it should either say dev after the build number or maybe Canary. I've got the beta build so mine reads Version 45.0.2454.46 beta (64-bit)
Version 45.0.2454.46 beta (64-bit)
