Answer 1

As you are using Firefox 3.6.*
There is a possibility that your connection dropped even briefly, more so if using wireless. Make sure Firefox is not set to "[v] Work Offline" in File menu just above Exit.
By default, Firefox '''3.5''' and '''3.6''' (as you appear to be using 3.6.18) will automatically use offline mode if there is no network connection. Under certain conditions, after the connection is reestablished it may remain in offline mode without the user's knowledge. Firefox 4.0 and newer prevents this behaviour by default by setting below preference to false. To prevent this behaviour in versions 3.5 and 3.6, add an entry to the '''about:config''' options, as follows.
* Type '''about:config''' in Location (address) bar
* Right-click on the about:config page to open the right-click context menu and use "New > Boolean" to create a new Boolean preference. Name: '''network.manage-offline-status'''. Value: '''false'''
