Some JPGs not showing - Pale Moon

[Mayayana]

Very strange behavior. I'm finding that
Pale Moon drops out some JPGs. I've tried
to narrow it down using a local webpage,
but even with the most basic HTML some
images are missing. I also tried updating
to the latest version of PM (15.1). Firefox,
which is said the be virtually the same
browser, shows the images fine.

Aha. I figured it out. This might be useful
to some. I had added a line to usercontent.css
to block web bugs, based on samples I found
online. It turned out the samples were wrong
and produced unpredictable image blocking.
What I had was this:

IMG[width*="1"] {display: none !important;}

I'm now getting 1x1 web bugs blocked without
blocking images by using this:

IMG[width="1"] {display: none !important;}
IMG[width=1] {display: none !important;}

The asterisk was the problem, and was not necessary.
