Hi,
Glad you solved your problem.

You didn't say from which previous version you updated but, yes, improvements to the wishlist have been made in the past - see
changelog
.
Generally, as with other if not all software, it is certainly recommendable to read changelogs before updating, and afterwards going through configuration settings to make sure it's all as you need or want it, particularly changed or added feature, to avoid unexpected behaviour.
However, as already stated, features like wishlist are not depending on browser type unless it depends on your logged-in status (like other ACL-dependent content) and you're logged in with some browsers but not with others.
