UA spoofing Gecko/<date> helps.
Ex. user_pref("general.useragent.override", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0");

Better to use the new site specific spoofing mechanism. Create a new string pref:
general.useragent.override.spaweditor.com

Use this as the value:
Gecko/[^ ]*#Gecko/20100101

Looks like this is fixed without needing Firefox code change, no need to track.

If the release log (latest release from 2008), the developer blog (last post 2008) and support forums (last post 2010) are any indication, then this project is dead.

[Dão Gottwald [:dao]]

Dead project can't be evangelized.

Attachment: SPAW UA Sniffing fix for FF >= 17

The user agent sniffing in SPAW editor is done by an PHP class placed in "spaw/class/util.class.php". I adjusted the detection for the gecko browser recognition - for everyone who might find it useful, as solmetra won't fix it. You can just replace the file with the attached one and it should work fine again (does for me).

Sorry, I didn't mean to post the full code here and can't figure out how to undo. I fixed this thing for FF >= 17.0.1 - as they seem to have rolled back the change, at least temporarily. My bad.
