Privacy Badger breaks 1Password

[cypherpunk]

On Firefox 41.0.2 (and a few versions earlier) having Privacy Badger enable breaks the 1Password FF add-on.

With it PB enable 1P is not able to communicate between the add-on and the application. I get errors that the add-on is not installed even though it is. I have talked to 1P and they aren't sure what the issue is. I have tried to reinstalling everything and nothing helps.

have you tried unblocking 1password domains? Click the privacy badger icon and click the settings button, then move any domains related to 1password to green (instead of red).

Odd, the 1password extension broke immediately, before PB was even warmed up on the VM. Adding these two entries to the whitelist didn't help:

• agilebits.com
• synapse.agilebits.com

Here's my interpretation of what 1password does:

After 1password is installed for the first time, you're navigated to https://agilebits.com/browsers/welcome.html that page appears to malfunction when PB is running.

Some resources are pulled in from https://da9ipfiyfnxgu.cloudfront.net/browsers/scripts/welcome.js and such, happily they didn't uglify and I can see some really well written javascript invoking a redirect to onepassword4-extension://activate/Firefox

So that part of it in particular fails. I don't know my plugin hacking, so it's almost a guess of mine that 1password registers this protocol, and uses it to perform settings changes on the browser/ plugin? I'm not sure what could be causing interference here, especially since 1password was broken before PB was doing anything beyond monitoring tracking... hmm...
