Broken by Default

I recently had reason to use Firefox's bookmarks' feature, "Open All in Tabs". I was unpleasantly surprised to discover that it closed my open tabs, and navigated away from my existing pages (including breaking my VPN connection to Borland's network). It's one of those features that's broken by default, by design, because - well, I don't know why. Apparently there's been some secret discussion somewhere 3+ years ago, that decided that the current behaviour is best. I have no doubt that the reasons are bogus :)

Anyway, I found out about about:config setting browser.tabs.loadFolderAndReplace, which fixes this behaviour and sensibly creates new tabs, rather than overwriting your current tabs and bringing your network down around your ears.

Here's another, more verbose link, describing how to fix the broken behaviour. Yes, I'm editorializing, but I'm just pissed because I had to fix everything back up again, after this "feature" exploded in my face.
