I don't use the Firefox RSS feeds, but I tried it myself, and it seemed to work fine for me.

Given that the error says "about:livemark" and not something like "syntax error" leads me to suspect that the Firefox RSS software (that's what Livemark is) may not be installed correctly on your machine.

At what point did you get the error?

For example, putting asterisks around a word and making it bold. Or underlines around it, and make it underlined.

At some point, I'll let you make links, but I want to build an easy way to zap spam, first.

Like the comments, just having a simple paragraph with no HTML made things easier to test and get off the ground quickly.

If you have HTML tags mixed in with your XML, you end up with so many more contingencies you need to check for and test.

also, will you be setting up some sort of cookie, etc. so that our username remains logged in each time we return?

thanks again. I know you still have a lot of things to work on, so we'll wait patiently as you do.

An invalid character was found in text content.

Ran it through validator and it says the invalid character is a curly apostrophe.

I also added the blog name to the titles of the RSS articles. Thanks, kcyanks1.

Permanent cookies, yeah, I'll do that later, too.
