OK, here's a puzzler for you.

[PeterAit]

I was typing away at a forum message and the screen font suddenly got really small. I expect I accidentally hit one or more keys I should not have. I am using Firefox. And what makes it puzzling is:

1) Other sites and the rest of the LuLa site are not affected, just the LuLa forums.
2) Using another browser (Edge) there is no problem.
3) Erasing all cookies and cached data  does not help.
4) Logging in with Firefox from a different computer, everything is fine.

Any ideas?

Yes. Your computer is a Democrat. Try a Republican computer.

Check out my examples in your own post in the About This Site subforum: https://forum.luminous-landscape.com/index.php?topic=133681.0

You will see that some of my fonts are also very small in the compose post area.

Are you using a Mac?

I found out the hard way that Firefox does not always work 100% on a Mac.  When I first bought this laptop, I was using Firefox to watch a news video, and, if the bandwidth of the internet is not fast enough to keep up with the video, Firefox may supplement the sound of the video with very loud distortion.  This blew the treble capacity of my speaker. 

Fortunately this happened within 2 weeks of when I bought and Apple just replaced the whole laptop for me.
