= Large numbers of Windows Temp Files and Internet Explorer Cache files =
Firefox uses the contents of temporary folders to improve your browsing peformance. In Firefox 3.5 the number of files used was increased, if you have a large number of such files this can cause Firefox to be very slow to start up. This is being addressed for the next release of Firefox. In the meantime, you can take the following steps to clear out these temporary files:

# Clear out the cached files in Internet Properties
## From the Start menu, select {button Control Panel}, then {filepath Network & Internet Connections}, then {filepath Internet Options}
## On the General tab, click {button Delete} under Browsing History
## Click the {button Delete files...} button under Temporary Internet Files and confirm.
# Delete all files and subfolders in the following folders (you may need to [http://www.bleepingcomputer.com/tutorials/tutorial62.html show hidden folders] to see and delete some files or folders).
** {filepath C:\Documents and Settings\<username>\Local Settings\Temp} (Windows XP)
** {filepath C:\Users\<username>\AppData\Local\Temp} (Windows Vista)
** {filepath C:\Users\<username>\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5} (Windows Vista)
*** This folder doesn't show up even when showing hidden folders; you need to type the full path into a Windows Explorer window to access the folder so you can empty it.
# Empty the Recycle Bin
# Windows Vista users can also use the [http://windowshelp.microsoft.com/Windows/en-US/Help/1264bc24-72a8-48aa-84e3-a355327139d91033.mspx Disk Cleanup Utility] to remove unneeded files.
If this problem returns frequently, you can lower the amount of space used for the IE cache (and have it clear automatically) by changing internet options:
# From the Start menu, select {button Control Panel}, then {filepath Network & Internet Connections}, then {filepath Internet Options}
# On the General tab, click {button Settings} under '''Temporary Internet Files'''
# Change the '''Amount of disk space to use''' to a lower number such as 100
# Click {button OK}

= Antivirus software =
Firefox reads a number of files normally during startup. Some antivirus software may do intensive scans of each of these files during startup and block access until those scans complete.
= Large numbers of fonts =
Firefox loads all your fonts so that it can allow websites to display pages in all available fonts. Having large numbers of fonts can slow down this process. Removing unused fonts can sometimes greatly speed up Firefox startup times.

= Extensions or themes =
Firefox loads extensions when it starts up and many extensions themselves add startup tasks. See [[Troubleshooting extensions and themes]] for steps on how to identify the extension that may be causing the problem.

= Refresh the font cache =
Firefox loads all your fonts using the font cache so that it can allow websites to display pages in all available fonts. At time, the font cache may be corrupted or too large. Refreshing the font cache can sometimes greatly speed up Firefox startup times.<!-- Bug 602792 comment 103 -->
{for win}
To refresh the font cache:
# Close all your Windows applications.
# With Windows Explorer, navigate to {filepath C:\Windows\System32}.
# Find the {filepath FNTCACHE.DAT} file and rename it in {filepath FNTCACHE.BAK}
# Restart your computer.
# Restart Firefox.
# Surf on various websites to populate the font cache again.
# Close Firefox.
# Restart again Firefox.

{for mac}
The easiest way to automatically reset all the font cache files in Mac OS X is to restart your computer in Safe Mode (also known as a “Safe Boot”):
# Shut the computer off.
# Press the power button.
# Immediately after hearing the startup tone, hold down the {key Shift} key.
# Release the {key Shift} key after the Apple logo and spinning gear (progress indicator).
# Restart the computer without holding down any keys.
# Restart Firefox.
# Surf on various websites to populate the font cache again.
# Close Firefox.
# Restart again Firefox.

{for linux}

# Close Firefox.
# Go to your '''Terminal''' and run: <code>sudo fc-cache -f -v</code>
# Enter your password.
# Once the font cache has been refreshed, restart Firefox.
# Surf on various websites to populate the font cache again.
# Close Firefox.
# Restart again Firefox.
