I have reinstalled my Firefox on my android phone and windows laptop and tried every trick in the book but I still cannot get the 'Edit' or 'Connections' menu to open on both devices. Same result with your demo when logged in as a user (
demo.cbdemosites.com/profiles)
FYI & In addition, when hovering on the 'i' icon next for example first name field on edit profile view the pop-up doesn't appear on Firefox browsers. Maybe this can be taking into account on the diagnostics?
Works fine on Google Chrome but I guess Firefox should be doing the trick too, right?
Maybe you've some more tips or ideas...?
