This describes their approach to basically every new thing they come up with, and as a long time exclusive Firefox user it's the one thing I really don't like about it. I find it to be a great daily-driver browser but every now and then they'll try to cram some new garbage down your throat.
At least they don't surreptitiously start siphoning your data with without asking first, though.
Edit: As for the screenshot thing being poor, I agree that labeling the upload button 'Save' was quite a faux pas but at least the icons are pretty clear. The 'download' icon is the same as the download manager icon, and the upwards arrow pointing to a cloud is a reasonable representation of 'upload'. I might even use this thing someday.
I for one am glad that it exists, I love Pocket, the only annoyance I have is that the Firefox integration is not as complete as the Chrome add-on, probably because Firefox users keep bitching and moaning about it.
It's great that you like Pocket. I think it's a bit rude to act like it's unreasonable to have qualms about how it was added (certainly pre-Mozilla owning them) or to be confused about it's inclusion while things like RSS reading/folders, (a not-uncommon browser feature) are removed.
This entire conversation wouldn't need to happen. There wouldn't be unhappy users. There wouldn't be "another side" calling criticism "bitching". They'd get active, enthusiastic user feedback, etc, etc.
Whenever suggestions pop up for migrating from freaking Chrome, which if we are honest is the new IExplorer 6, to Firefox, somebody has to mention freaking Pocket. And it's tiresome and I don't think it is legitimate.
The presence of Pocket's integration in Firefox can't possibly be the reason for why somebody doesn't want to migrate from Chrome.
