It seems about half the time I try to use the 1P extension in Safari in the last few months, it hasn't worked. Sometimes if I do a bunch of the troubleshooting stuff it comes back, sometimes not. The most frequent problem is the Command+\ shortcut does nothing. This time when that happened, I did all the troubleshooting steps in the extension Troubleshooting menu, still didn't work. Turned extensions off and back on, option-quit safari, still nothing. Opened 1P app and updated it, said yes to the dialog to update extensions, but it didn't. I deleted the extension in Safari and manually installed it from the 1P app. I love this system, but it's getting to be somewhat unstable and high-maintenance.
Currently I have 3.8.8 extension, 3.8.12 app. Any suggestions to make it work?
