I updated Firefox Quantum to 57.0.1 (64-bit) and 1Password Firefox extension icon started to flash. And it doesn't work either. When I call 1Password mini it indicates "Add Firefox Extension..." as if there was no extension installed.
I have found a newer version from Firefox Quantum (57.0.2). After installation the same error occured.
Anyone else with the same problem?
1Password Version: 6.8.5
Extension Version: 188.8.131.52
OS Version: macOS Sierra 10.12.6
