I wanted to like this, and still do want to like it, but I'll have to uninstall and try again in a few weeks, hoping the bug has been fixed.

The bug: "Golbal settings" is pre-selected and can't be un-selected. Blocking videos on usatoday.com works great, but means I can't watch videos on youtube or Amazon prime.

"Image Video Block" (all blocking settings are disabled) blocks the load of builds for Diablo 3 on the site "d3planner.com"

Good useful extension. One hurdle, Should have been able to create Black List and not White List as Black List will be less in comparison to White List.
Reviewing the add-on as the developer is not interested to listen to users.

Missing shortcut to turn it on/off quickly

No tool bar menu to quickly disable/turn off pics and/or video? Really?

I'm kind of shocked that in 2017, I have to open a FF extension page and click in tiny boxes at the bottom to control the plugin.

If it isn't already in the roadmap, I would urge the developer to please consider taking a queue from uBlock Origin and write a simple toolbar drop-down menu to control the functionality of this plugin, it will make it worth using.
