Hello Frank. Firefox is, in general, fast to open. You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal? Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way. If you want support for one of your add-ons, you'll need to contact its author. However, some older computers may have trouble handling applications (Firefox included). If this lack of performance is widespread in your system, you may need to get a better system... Or your operating system may be in need of some maintenance. Contact your OS's developer for support if you need help maintaining your OS (or ask someone you know who has experience, if you don't have it).
