The contribution one page checkout ([url removed, login to view]) is installed and adapted to my osCMax website.
1- It is working perfectly with IE8 but the shipping and payment methods are not refreshing automatically under FF (see [url removed, login to view]), even if I delete the cache of my browser.
2- As it is not working, I didn't activate the contribution but I don't know why but since this contribution has been installed, the customer fields are empty in admin/orders with regular ordering (see [url removed, login to view]) when this error doesn't occur with one page checkout.
3- some languages define have to be added ("Please fill in your billing address for payment options" and "Please fill in at least your billing address to get shipping quotes.")
This fix has been added 4 days before at [url removed, login to view]
These 3 issues have to be corrected for the contribution to work with any browser. I guess the fixes have been added at [url removed, login to view] as the contribution has been installed on my server at the beginning of May and some bugfix have been added.
