Receiving lots of errors while browsing. Firefox on Win10 pc.

Using Firefox on Win10 pc, the usual add ons. Errors when upvoting, when accessing posts from inbox, when expanding comment trees.

Errors repeatable until page loads either by refreshing or pressing back. Once the page has loaded without an error everything seems to work fine, up and down votes, expanding comment trees, etc all work even after navigating away from post and returning.

Happy to provide any other information that helps diagnose things.

Thank you. I really like wefwef!
