The Pulse service merits a 5 star review. It's by far the best of its type I've tried (and I've used all the major competitors extensively). In fact it's the only truly reliable one out there in my experience. Highly recommended.

This add-on however doesn't work for me - it shows no content. I reported it and got a slightly dismissive response from the developer, basically a 'won't fix & won't investigate'. Not a hanging offense, as there's a substantial opportunity cost to support, which can be too much to bear for a small (one-man?) team.

If you have similar problems with this add-on, just keep the pulse web app open instead. It is an excellent service.

Love the app and use it on many different platforms, but the Firefox extension does not show notifications. The option is in the add-on settings, but it doesn't stay checked when you check it. Not sure what is going on.

Works with messaging, but every time the the button is pushed it has to reload the source and the popped-out window is impossible to move.
