I had a Dell Latitude E6220 on 32 bit Windows 7 SP 1 and each time I'd open up Firefox in any profile, the screen was totally black. This did not happen in safe mode (hold down shift while starting Firefox) or when I RDP'd to the computer. I reset Firefox settings to no avail.
The solution was to disable hardware acceleration via Options -> Advanced. If your Firefox is opening up with the black screen, you can disable hardware acceleration in safe mode.

Speed test that doesn't require Flash
When I'm running a speed test on a server, I'm often in a small bind as I can't run my standard tests at www.speakeasy.net/speedtest or www.speedtest.net since most servers don't have flash and it's typically an obstacle to install it.
I found an HTML 5 speed test at www.speedof.me which works just fine, which works just fine on Firefox, which is typically my default browser.

Firefox will not display SSL enabled web sites - Sendori alters SSL certificate appearance
I was working on a computer with Firefox 20.01, and the browser would not display any SSL secured websites - not google, not facebook, not Citibank, not anything. Chrome and Internet Explorer had no trouble with these sites.
What I found was a piece of software called Sendori that was installed the previous day that had somehow altered the SSL cert information for each site. Example is below for the cert that was showing for Google.
I tried uninstalling Firefox, opening a new profile, deleting cert8.db and all sorts of things. But it was this Sendori program altering certificates that was my problem. I could see that Sendori was listed as the certificate issuer and the "valid from" date was set today for all SSL sites.
I was able to uninstall Sendori from add/remove programs.

AT&T Uverse error on google - 404. That’s an error. The requested URL /cgi-bin/redirect.ha was not found on this server. That’s all we know.
One of my clients recently changed their internet service to AT&T UVerse. AT&T (in San Francisco) says they are no longer offering DSL, only UVerse. After setting up UVerse, one of my users was getting this error in Firefox when going to www.google.com:
404. That’s an error. The requested URL /cgi-bin/redirect.ha was not found on this server. That’s all we know.
She got a similar error when going to www.yahoo.com. After some research, this seemed to be a common theme in Uverse. I resolved this by clearing the cache in Firefox:
Annoying, but easy fix. Of note - she did not have this issue on IE 9. Just Firefox 11.
