I've heard a bunch of people having problems with the games load time getting worse and worse as the game progresses. One of my friends told me that he was having that problem, but he turned his autosave option off in his settings and that fixed it for him. Maybe that'll work, and if not, I think you might just be s.o.l.

If you were able to load websites until you updated Firefox or until your Internet security software was updated, reconfigured or a new one was added, your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more) is likely preventing Firefox from connecting to the Internet.

In general, you should make sure your Internet security software is up-to-date and remove Firefox from your program's list of trusted or recognized programs, then add it back. For instructions on how to configure some programs, see the Configure firewalls so that Firefox can access the Internet article.

Check for malware

If clearing your cookies and cache did not enable you to load the websites that did not work in Firefox, you should check your computer for malware. Certain types of malware are known to target Firefox and can prevent it from loading various websites:

• If you have an antivirus or Internet security program, update its detections database and do a full scan of your system.
• If you still have problems, follow the instructions in Troubleshoot Firefox issues caused by malware.

A Firefox extension could be causing the issue, especially the ones that have network access and/or those that rely on manipulating webpage content. Try disabling your extensions in the Add-ons Manager one by one and then reload the page. See Disable or remove Add-ons and Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems for more information.
