Thanks Tig, I had a feeling that was the answer but it's not stated anywhere official that I can see.

Hi all,
my 1st post, so hello!

Is it possible to install extensions in the Free browser version? Specifically I was looking at Roundcorner by Fredo6. It does mention working in the free version but whether that meant 'Make' or 'Free' I'm not sure. I've dug around in various instructions and they all seem to refer to menus that don't exist in Free.

Thanks in advance,
M
