I needed to return an item so went through the return request process.
I selected 'not as described' as the reason from the pull down menu.
However the expected 'Confirm' button was missing when using Firefox.
I repeated the process using MS Edge.
This time a blue 'Confirm' button was displayed and I was able to proceed.
My question is: Why does this not work in Firefox?
Note: My Firefox Ublock Origin ad-blocker was disabled.
