Yes, I can confirm this. It's been reported in our tracking system as:
#25973: Composer doesn't work on firefox 3.5
Unfortunately we haven't been able to investigate this in greater detail so there are no known workarounds at this time. If anyone has found a way you're more than welcome to share.
Det här kanske kan vara av värde? Har för mig att Composer använder rico?
Yes, composer is using Rico. I'll add this information to the issue.
Thanks for the feedback!
I think I've fixed this bug, don't know if it's already fixed in 3.2.6 rc1 though? It is a bug in rico, a property that collides with a new reserved keyword in ff. I implemented the fix found in Rico rev. 55 into the existing rico.js used in Composer. It's as simple as changing the name of a property in three places.
I havent tested it that much but so far it seems to work in ff 3.5 on windows at least.
To be more specific, check this out:
(Edit:) ..it gives you the exact code changes for fixing this problem.
(Btw, thanks for the tip, Ulrik!)
This is my modified rico.js that works in FF3.5. The original is from Composer 3.2.5
Thanks Ulrik and Magnus. We'll verify and add the fix of Rico in the next release of Composer.
