Thank you for your reply.

A few quirks here and there - but I expected more.

The reason I mention it here is that until the recent changes here everything was working properly. I can't upgrade the browsers unless I also buy a new computer ...

 But I have found TenFourFox, a variant of Firefox, which works fine.

I attach a small image to show how Firefox displays the boxes I can't click.
