after upgrading to ata3.7.3 I have to use IE8 to work in ATA theme options.
The options are not clickable in firefox
Is this a known issue?
edit:
My wp multisite with ata is accesable in firefox so only my singlesite ata has an error!

I work in firefor with 3.7.3 all the time.

Try disabling all your firefox add on's

Thanx Juggledad, i've disabled them al, started the addons on by one and no issue animore, didn't find the couse but it works with all pluggins active now
