padlock icon has an exclamation point on secure websites
Suddenly, everytime I log into a secure website, the padlock icon has a red exclamation point in it. The message says "Warning, contains unauthenticated content." When I click through to the certificate, it says "This web site does not supply ownership information." Under technical information it says "connection partially encrypted"...
This has never happened before. What is the problem? I can't use my computer for any bills or banking now.

A web page usually consists of many individual items, such as the page itself, the images shown, plus advanced things as stylesheets, scripts, etc.
If you get the red exclamation mark, it means that one of the individual items was loaded without https/SSL protection.
It you really get this for each https/SSL site you're visiting, that would be a bug in Firefox, and please report back, including a list of example sites.
However, most people see this only for one site, or maybe a couple of sites.
The fix is to contact the webmaster of that site and ask them to fix their site. If a site is supposed to be using secure protocols, but is doing so incomplete, that's a mistake made by the operators of that site.
(Please note that Firefox 4 will no longer show a lock icon at all. This makes it more challenging to notice a site with mixed security, because the new security indicators will simply go away in the mixed scenario.)
As posted above, you shouldn't see it on all sites.
Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
- Don't make any changes on the Safe mode start window.
- Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
- Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Troubleshoot Firefox issues using Safe Mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
