I'm a web developer and use the error console in Firefox a lot.
I'm noticing a great deal of errors from the 1Password plugin.
This one is the most common:
Error: ReferenceError: sjcl is not defined
Source file: resource://onepassword-at-agilebits-dot-com/onepassword/data/src/popup.min.js
I'm seeing the above error plus another one at work, but cant seem to provoke it now. Will post it tomorrow, lest I forget.
It'd be really nice to have these errors fixed as they pollute the error console window, which interferes with getting work done.
