Camino is based on the Gecko engine, so I think it should work too if
it is based on a modern gecko engine. Any browser based on a modern
Gecko engine should work. *However*, continue reading.

After applying the changes, a new text appears saying if it went ok or
not. Anyway, you can look at the page "about:config" and look for the
properties browser.dom.window.dump.enabled (should be the *boolean*
true) and browser.sessionstore.resume_from_crash (should be the
*boolean* false). I say *boolean* because these values as strings
instead as booleans won't work.

Yeah, the YWMS plugin is just a server for the wmsplugin

If you installed the wmsplugin *before* configuring YWMS, the URL is
added automagically,

Please, start JOSM from console (java -jar josm-latest.jar) and look
at the output. It should say what failed.

**HOWEVER**: I have reports from two people saying that  the Firefox
feature I use for dumpling  the loaded page as an image is bugged and
is not working in Max OS. It may be useful to test if Camino does it

Start Camino with the environment variable
MOZ_FORCE_PAINT_AFTER_ONLOAD=/tmp/test and load any page,
www.google.com,for example. Then open the generated files /tmp/test-*.
Firefox in MacOS makes nearly black ppm images. Actually, it makes
dark red images with only one color channel. If Camino does it right,
