I reinstalled JAVA but on websites AJAX is still corrupt and giving my AJAX errors!

Question

I have totally uninstalled and reinstalled Java and also uninstalled and reinstalled Firefox 3.6.. But on sites that use AJAX I still get "ajax error , or something that tells me ajax is corrupt".. Otherwise javascript and java works fine. I even tried without any extensions and all default settings. I seems this is also affect my other Opera and Chrome browsers.. AJAX is corrupt and short of reinstalling Windows what can I do to fix it?

Answer 1

The proper way to close Firefox is through the File menu "Exit" or the equivalent with the Firefox button.

Firefox already running, to properly shutdown Firefox when closing the last window use File → Exit/Quit (or Firefox button → Exit). Closing Firefox with the [X] in the upper right corner closes the window ("Ctrl+W") but that does not necessarily close Firefox if it has subtasks running. If you want to close and reopen Firefox use the "Restart" within Add-ons if you made a change requiring a restart, or install "[https://addons.mozilla.org/firefox/addon/restartless-restart/ Restartless Restart]" ("Ctrl+Alt+R") which will allow you to take Firefox down and restart without having to check the Windows Task Manager to see if Firefox first actually ended.
