At random, well known sites, I randomly get a pop-up window that says, "The URL is invalid and cannot be loaded." Firefox does load the site but I must click out of the pop-up to proceed.

What gives? I'm running Windows 7 on a new HP laptop

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")

The culprit was the Google Toolbar 7.1.20100830W. Does this mean it's a bug in Firefox or the Google Toolbar extension?

~ I HAD THE SAME PROBLEM WHEN TRYING TO WATCH NETFLIX MOVIES ONLINE SO I HAD TO SOURCE IT MYSELF BECAUSE NOONE ELSE HAD THE ANSWER, THESE ARE THE STEPS I TOOK: (MOZILLA FIREFOX 4)

1. MAKE SURE YOUR NETWORK SETTINGS ARE SET TO "AUTODETECT SETTINGS FOR THIS NETWORK", (TOOLS--> OPTIONS--> ADVANCED--> NETWORK--> CONNECTION SETTINGS--> "AUTODETECT PROXY SETTINGS FOR THIS NETWORK"

2. DISABLE ALL EXTENSIONS; (TOOLS--> ADDONS --> EXTENSIONS) (I ALSO HAVE AVG ANTIVIRUS, SO I HAD TO DISABLE THE AVG TOOLBAR EXTENSION)

3. DISABLE MOST ADDONS EXCEPT ESSENTIALS LIKE SILVERLIGHT, SHOCKWAVE FLASH , & JAVA PLATFORM; (TOOLS--> ADDONS --> ADDONS)

~ NOTE: IF YOU HAVE MORE THAN ONE AUDIO/VIDEO PLAYER THERE MAY BE A CONFLICT.

4. IF YOU HAVE ITUNES IT WILL INSTALL QUICKTIME AS THE DEFAULT HANDLER OF APPLICATIONS IN YOUR BROWSER, SO I HAD TO UNINSTALL QUICKTIME WHICH I NEVER USE.

5. IF YOU HAVE REALPLAYER, IT MAY ALSO CAUSE CONFLICTS WITH YOUR ADDONS & OTHER AUDIO/VIDEO PROGRAMS, SO I UNINSTALLED IT SINCE I WAS ONLY USING IT TO RECORD & DOWNLOAD INTERNET VIDEOS (OPTING FOR A SIMPLER DOWNLOADER)

6. I FINALLY HAD NO PROBLEMS WITH INSTANT WATCHING OR URL INVALID PAGES ON NETFLIX, ETC., AFTER FOLLOWING THE PREVIOUS STEPS. 

                                                             GOOD LUCK
