Thank you for the feedback, and I’m sorry for not replying sooner. I don’t check reviews on the Firefox Add-ons store very often; if you’d like the fastest response, please consider opening an issue in the project’s GitHub repository.

As far as I know, the button in the address bar is part of Firefox’s built-in Pocket integration, not something implemented by in-my-pocket. Regular browser extensions don’t have the necessary permissions to replicate this behavior, so unfortunately it’s not something I can support.

You’re right that the current way of adding tabs is a bit cumbersome, as it requires opening the popup and then clicking the add button. I’m considering some improvements, such as adding a keyboard shortcut or other, more convenient ways to add tabs. This is still being explored, and I expect to release an update within the next few days.
