New github repo – https://github.com/bswopes/FoxReplacements/blob/master/SomeAsshole.json
I’ve created this as a substitution list to replace the names of mass shooters with “Some Asshole”. So far, I only have the Oregon shooter and his inspiration from Isla Vista. Please feel free to share and submit pull requests with new names or fixes.
FoxReplace is available from the Mozilla addon store: https://addons.mozilla.org/en-US/firefox/addon/foxreplace/
Let me know if there are any compatible plugins for other browsers.
