I really like this extension but for a while now it's not working on my home computer, even if I uninstall and reinstall it. The sidebar opens when I click the Brief button in the toolbar but no feeds show up and clicking on anything (like options, refresh, etc.) does nothing. This is version 2.5.8. Works fine on my work computer, so not sure what the deal is.

Update 7/3: This is really messed up but to get Brief to work again I had to go into my Firefox roaming profile and delete all the websites in the "default" folder in the "storage" folder under the profile.
