This plugin is archived as Discord has since patched crashers.
This is a Powercord plugin, you must use git clone https://github.com/1Lighty/discord-crasher-checker
in the plugins folder.
Quickly (as quickly as it can and as quick as your internet is) checks over GIFV's and videos to make sure they won't crash your Discord.
This is effective against almost all crashers that I am aware of, if you notice one slipping past, please let me know privately via DMs so I can take a look.
