JavaScript tracker fails on Firefox with "Always ask" setting for cookies

[alexanderdean]

With "ask me every time" set for site cookies:

the JavaScript tracker fails to execute with "SecurityError: The operation is insecure".

Some related posts around the internet:

• Bundled html4+5 jQuery throws "SecurityError: The operation is insecure." Firefox 14 browserstate/history.js#199
• http://blog.bcholmes.org/meteor-firefox-cookie-settings-securityerror/

To fix this: we need to run the un-minified version on Firefox and dive into the error line.

To resolve this I added this function :

var storageCheck = function(){
try {
window.sessionStorage.setItem('History.test',true);
} catch (e) {
return false;
}
window.sessionStorage.removeItem('History.test');
return true;
};

And replaced:
sessionStorage = window.sessionStorage||false
by
sessionStorage = (storageCheck())?(window.sessionStorage||false):false

Awesome - big thanks for sharing @featureless !

Scheduling to add that into the next release (which is a JavaScript-centric release)!

Update: error is on line (when snowpak'ed without compression) 2468:

!!window.sessionStorage,
