It's truly made browsing Tumblr feel enjoyable again! I am rating this five stars, despite what I'm about to say, because I honestly feel so grateful to you for providing this amazing extension.

Like someone else said recently, it stopped working for me a short while ago. I'll describe my issue to the best of my abilities.

All features that the extension provides have gone kaput. The "original posts"/"all posts" tabs are still visible, but switching to "original posts" leaves it loading, seemingly permanently. I've tried opening up the extension, but it is stuck on the "all features" tab, with no feature listings actually showing up. I cannot switch to specific features (like "posts" or "dashboard"). It does the animation to indicate I'm hovering over it, but clicking it does nothing. Same goes for trying to click "manage" or "about".

Strangely, this issue doesn't occur in vanilla Firefox, but does occur in Zen Browser (a Firefox fork, and my main browser). I've tried updating Zen Browser, turning off all other extensions, fully quitting Zen Browser then restarting, and restarting my computer, but all have turned up nothing.
