Why do all internet pages I open with Firefox (except Mozilla) look like they are in start-up mode?
I have both Internet Explorer and Mozilla Firefox on my laptop. I have had this for almost 2yrs without issue. As of this morning, when I open any web page with Firefox it opens in what looks like "safe mode" or takes way too long to load then without pictures. Only text and links. I uninstalled Mozilla and Re-Installed Mozilla. I cleared cache, cookies etc. Only the Mozilla homepage shows up as expected, all other pages have a problem. I am not having this problem using IE8.

Hi,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
To Reset Firefox do the following:
- Go to Firefox > Help > Troubleshooting Information.
- Click the "Reset Firefox" button.
- Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
- Firefox will open with all factory defaults applied.
Further information can be found in the Refresh Firefox - reset add-ons and settings article.

If the problem persists, you can also try to Disable McAfee via Tools (Alt + T) > Add-ons > Plugins and check. If you have security software (antivirus, firewall etc.) installed, you may also have to delete all existing instances of Firefox and its related processes/files in all the different configuration modules/areas of the security software like process monitoring, sub/spawned process control, virtualization, HIPS etc., in addition to the security software's main configuration panel. Instead create new fully allowed/trusted rules for Firefox + its related processes in all the different modules/panels - a genuine/original Firefox installer as well as all the installed EXEs (Application) and DLLs (Application extension) are digitally signed by Mozilla Corporation (right-click > Properties > Digital Signatures). Even otherwise, some security software may also ask again when Firefox and/or its sub processes are started, and you may be able to allow/trust at that time. Please see this.
A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
