I'm not working with userscripts at the moment, I just noticed the following error when checking the Network tab for the page I'm working on to see what it's doing (It's taking forever to serve my GET request).
Uncaught ReferenceError: unsafeWindow is not defined
chrome-extensions://bpcnnanbbiobnpfamcdpkopledhphmh/fbex.js:864
Can anyone tell me what this is?
Thanks!
