I've just installed Firefox and see that it has a "safe mode". If I use unsafe mode, what effect will it have on Windows and Internet Explorer? Jeremy James
Most Firefox users install extensions (https://addons.mozilla.org/extensions.php?app=firefox) and themes to customise it. Sometimes these cause problems. Safe Mode lets you start Firefox with no extensions, themes or customisations, temporarily, so you can remove the offending add-on. The opposite of Safe Mode is not unsafe! You don't need to change Windows or IE.
