Page Dark από Marnes

This addon won't be maintained further. I'm shelving this project due to lack of interest/utility and too much burden. The addon will remain available for download as long as the store allows, and the source on gitlab will also remain available to fork.
I do have a greasyfork account and may publish works there in the future. I have mild intentions to reimplement the core functionality of CSL, IBCP, and DID as public userscripts.

Available for Chrome too.

Functionality
Page Dark covers the webpage with a black screen when you click the toolbar button or trigger the hotkey. Everything except media like videos or games, frames and Flash objects will be hidden by it. This allows you to watch online videos, play Flash games, etc in a much more enjoyable way.

FAQ

• How do I configure the hotkey?
  Via your browser's generic addon hotkey settings.

A lot of time and work goes into creating my addons, and making changes or troubleshooting issues for users.

Problem, bug, broken, question, request?
Please use the linked support site or email for all non-review communication. AMO policy protects both users and developers by demanding certain quality standards from addons as well as reviews. Severely disfunctional addons are not published. Reviews and ratings must consider the entire addon, set reasonable expectations, and be timeless: a bad rating focusing solely on a systemic bug or on a problem not suffered by other users will stay long after the issue is resolved. AMO also gives extremely limited communication abilities, so contacting me properly will get your issue resolved much better and faster.
