WSJ Oddity
I've seen this before with Wall Street Journal articles; I suggest caution with the link below, as these feeds have a tendency to crash FF without engendering the FF crash reporter.) Due to strange behavior of such feeds, I suspect the problem is with them, rather than with Brief, so this is to bring the syndrome to Ancestor's attention in the hope that he can decipher what is the cause and, perhaps, a fix therefore.
Specifically, http://online.wsj.com/article/SB125630742754903935.html?mod=rss_Today%27... . (I don't know which of my Brief rss feeds provided this article: I was looking at all of my Brief feeds in one set, rather than looking at the individual feeds, and I don't have a specfic rss feed for the WSJ.)
When I click on such articles, a new tab opens (using TMP) as expected, and then the tab that Brief is in changes to the article, and the new tab is empty. I can read the article in Brief's tab, then go back to Brief in that same tab, and I can close the empty tab.
