Google Toolbar does not respond to search requests. Nothing happens when I click the search icon. When I try to uninstall it, nothing happens. When I click the Add Ons option in the Firefox Tools menu, it causes the program to crash. And while it is crashing I get an error about ndExtensionManager.js631 I think.

Having this exact problem; by any chance are you on Windows 7 and did you update your system last night? It installed a "compatibility update" for various programs and I think this is what started my issues.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

You can use "Disable all add-ons" on the Safe mode start window to disable all extensions.

You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
