I am using the 1PasswordX browser extension for Firefox 67.0.4 (64-bit) on Linux (Fedora 29). I am using the Wayland compositor and the default GNOME 3 shell.
Since a recent 1PasswordX extension update and Fedora update (not sure which), I am seeing the issue described below, which has symptoms very similar to an issue that was previously reported on Ubuntu (https://discussions.agilebits.com/discussion/98113/1password-on-firefox-linux and https://discussions.agilebits.com/discussion/90011/lock-screen-issue-1password-x-for-firefox-on-ubuntu-18-04).
However, since Fedora 29 uses Wayland as the compositor and is usually quite up to date so would presumably have a fixed version of ibus / gnome-shell it may be a different issue
Upon starting Firefox, I am not able to unlock 1passwordx through either clicking on the toolbar or using the keyboard shortcut. Presseing either of these results in the 1password window flashing up briefly and disappearing again.
Logging in through the web interface (https://start.1password.com/signin) makes the issue go away until 1passwordX is locked again, either through timeout or explicitly by me locking it.
I reproduced this issue even with all addons except 1passwordx disabled.
