In the process I discovered that someone has hacked a fix to this bug. To enable these, enter about:config in your address bar, and then change the setting browser.xul.error_pages.enabled to true. For those who don't want to click on the link, what this does is instead of error dialog boxes coming up messages about not being able to reach a server or timing out, you instead get a web page. Takes a bit of getting use to, but it makes tabs even faster, since previously if you get errors in the past while loading tabs in the background, you'd have to click "OK." Now, the tab will load just fine.
I also found a "Show Failed URL" extension. Most Mozilla users probably know that when you get an error, Mozilla doesn't keep the address in the address bar. Kind of annoying if you just want to hit reload to try and get the page again. This extension fixes that.
Sorry for the geeky post . . . but sometimes it's just the little things that make the world better . . .
