@smoxy Of course!

FYI, I did not install Firefox via Snap. Importantly, I installed Firefox daily from a Ubuntu ppa, which has a binary name of firefox-trunk. Your binary name might be different, so this needs to be changed in the following.

I was sent the following by mail by a support employee:

  1. Ensure that browser integration is enabled from Settings → Browser.
  2. Close 1Password completely.
  3. Open a terminal, and run sudo mkdir /etc/1password (if you've done this already, you can skip it).
  4. Run cd /etc/1password.
  5. Run sudo gedit custom_allowed_browsers.
  6. Paste in the appropriate browser code - in this case firefox-trunk. (ie the binary name)
  7. Save the file.
  8. In the terminal, run sudo chown root:root /etc/1password/custom_allowed_browsers && sudo chmod 755 /etc/1password/custom_allowed_browsers
  9. Run 1Password - it will read the new config file and make the appropriate connections.
  10. Launch your browser!

Doing this resolved the issue for me!

Cheers,
Tobias

I realize this is an old thread, but I am enountering the same issue on a Lenovo X1 laptop with Ubuntu 24 LTS. I use default firefox (snap), but I also tried chromium (snap). I followed your instructions to the letter; I looked for processes using 
ps -e | grep pass
and killed all processes as appropriate
My /etc/1password/custom_allowed_browser
contains the lines:
firefox-trunk
chromium
chrome
but none of the browser-plugins connects to the main 1Password app when it is running. I can log on to the 1Password app with fingerprint after starting it with the 1Password password, but both browser plugins report a communication problem in their respective settings pages.

Any help will be appreciated!

    I searched the internet some more and found the solution. My starting point: I was able to integrate the 1Password standalone app with system authentication/fingerprint reader, but the 1Password plugin in the firefow browser reported a "Communication Errror" with the standalone app. The problem is that Ubuntu installs Firefow via snap. You need to install Firefox as standalone from the Mozilla repositories with apt, not snap. There are some detailed instructions under https://askubuntu.com/questions/1516223/how-to-install-firefox-from-official-mozilla-repository-on-ubuntu-24-04 . The process took about 10 min, but then everything worked.
