I'm very confused by this. I have a Firefox add-on/extension, Pocket (formerly Read It Later), which seems to still work although I am OS 10.6.8.
But now there is this app, which apparently connects to all browsers -- although who knows for sure, as the product description is very vague, and the video at the developer's site is even vaguer -- however it is only for OS 10.7+.
To confuse matters further, when I go to FF's add-ons page and look at "Pocket", it calls it version 3.0 (like this application here) but the download is called read_it_later-3.0.0
Can anyone explain, please? As the "developer"'s page is bereft of pertinent information
