Does the latest version of firefox (44.0) have a problem storing cookies where the name of the cookie contains a space?
Hi,
I have javascript code that is run to create certain cookies. Since updating to Firefox 44.0, it would seem cookies don't get stored if their name contains a space.
Cookie that does not get created anymore (space inbetween 'Full' and 'text': document.cookie="text_searchfield_ROW0LIBRIOS2SEARCHFIELD[Full text]=england; path=/";
There's a space because these names have to be generated dynamically.
This is causing a bit of stress as there's a lot of websites dependent on this.
Any feedback would be appreciated.
Adam.

I have posted the site compatibility doc: https://www.fxsitecompat.com/en-CA/docs/2016/whitespaces-are-no-longer-allowed-in-cookie-names/
Yeah, some apps might be broken due to this change. Mozilla developers are now aware of the issue, and Firefox may allow spaces again for backward compatibility.

Maybe forget the bit about 'causing a bit of stress'. The code has been updated affecting my sites.
Definitely want to make you aware in case though.
Perhaps this is a regression from a cookie-related security issue fixed with Firefox 44. But, I believe you have to encode the value anyway before being saved, because white spaces are not allowed. See https://developer.mozilla.org/en-US/docs/Web/API/Document/cookie
Filed a bug to make sure this change is intentional.

Thanks for the response Kohei.
I agree, we should have been encoding these names - we just didn't realise we weren't encoding them until version 44 stopped them from working.
I'm sure there'll be a few others getting caught out with this.
Thank you for you time.
