I can start Firefox but no data is loaded on the page. I get the toolbar and the background but no data. The address bar is blank. No error messages, including java script console, are displayed. I get the same results for all Web pages, not just the home page. There are no virus's detected by Kaspersky antivirus (KAV). I was able to previously display Web pages with Firefox. I can display pages using IE.
I've tried the following:
uninstalled the old version and installed the most recent version of Firefox
cleared cookies and cache
added a new profile
ran Firefox with both Windows firewall and KAV turned off
deleted the mozilla and profile folders after uninstalling Firefox
I also cannot restore to a previous checkpoint. Windows hangs while creating the restore files. Not sure if this is related.
