Facebook Post Screenshot — hckr

Web Extension to save Facebook posts as images ("take screenshot"). Add-on adds new option in each post's menu to save it's screenshot (with all replies expanded). Screenshot can be also anonymized (profile pictures blurred, names replaced with identifiers like "OP", "Profile 1", "Profile 2" and so on). Large posts are split into multiple images each at most 8192 px tall (this can be changed up to 16000 px).

Warning: the add-on does not work correctly when Facebook is opened inside a container add-on, such as Facebook Container or Multi-Account Containers, and in private windows (issue tracker).

Also, "save screenshot" doesn't show up for some posts on the wall, but it should always work in the single post view (issue tracker).

You can file bugs and suggestions in the issue tracker on GitHub. Facebook changes the interface from time to time which causes the add-on to stop working partially or even in full. Instead of giving a one-star review, you might consider filing an issue – I'll surely try to fix it in my spare time.

If you like the add-on, you might consider giving it a star on GitHub.

WHY DOES IT REQUIRE ACCESS TO DATA FROM ALL PAGES?
It is required by the browser to make screenshot of the page using canvas API (see also this bug report). The add-on does not execute any code on sites other than Facebook and add-ons homepage. If you'd like to check it yourself, the code is publicly available (see "Version Information" below or on GitHub).

WHY DOES IT REQUIRE ACCESS TO DOWNLOAD FILES?
This permission is used to download captured post as images.
