I'd like to add a couple of lines of Javascript that will automatically log me in my email once the page loads (my provider has no "remember me" option. I found an extension [an extension](https://addons.mozilla.org/en-US/firefox/addon/javascript/) that allows me to do this, but unfortunately, my email provider has a strict [CSP](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP), and the extension is blocked.

Is there any way around this? Can I tell Firefox to ignore the CSP for this one webpage, or maybe run some Javascript automatically via dev tools?

Turns out if I use Greasemonkey instead of the other extension, the script isn't rejected. Never mind!
