This add-on shows great promise, but it doesn't seem to work well right now.

I spent a whole morning the other day investigating various options (none of which worked well) for mirroring Android notifications on a PC. I was pleasantly surprised to learn that the PushBullet I haven't used for years actually does exactly what I need, and does it very well!

The Android and Windows PushBullet apps work very well and I imagine the XUL plugin does too. Right now, a week or two after the release of Firefox 57, this new WebExtensions plugin has some issues. It doesn't maintain logged in sessions over restarts (probably Firefox's new 'security' stuff blocking things) and the UI is broken (squeezed into a tiny window) if I pin the PushBullett icon to the overflow menu on Firefox's toolbar.

Not quite there yet with this new version of the plugin, but looking very promising! Thanks folks, keep up the good work!
