I have various browsing sessions, one is for email, one for studies etc. With one of the browsing sessions when I try to close a tab, firefox asks if I really want to close this tab, because for some reason it thinks I'm writing a message. This is really starting to get on my nerve, not because of firefox, but because of the website that triggers these popups.
Is there a way to disable these?
I've trying so hard to find an answer, so I would be really grateful for your help!

That is caused by a script that run on the page and is triggered by an onbeforeunload event
You probably can't disable such a warning alert, but you can check if you can find a Greasemonkey script to disable such an event
- void(onbeforeunload = null);
- Greasemonkey: https://addons.mozilla.org/firefox/addon/greasemonkey/
Years before, I set up a setting to block onunload from opening popup windows on some advice from a website.
Will that still work with the current release of Firefox? If not, will this work?
