Clippings extension

The Clippings extension helps you quickly paste text you frequently type in forums, and is a great tool for doing user support. Get it here.

Snippets

Crashes

Go to the address '''about:crashes''' and tell us your latest crash IDs. We can then look at the data specific to your crash and have a better idea of what is causing the problem.

Safe mode

If you go to '''Firefox > Help > Restart with Add-ons Disabled''', does the problem still occur? If not, the cause is probably an extension. See [[Troubleshooting extensions and themes]].

Test profile

Your Firefox settings and info are kept in a folder separate from the Firefox program, called your profile folder. Try creating a test profile, to see if the problem still occurs. See [[Managing profiles]]

Try clearing cache and cookies

# Open the '''Tools''' menu, then select '''Clear Recent History'''.
# In the '''Time Range to clear:''' drop-down, select '''Everything'''.
# Click the arrow next to '''Details''' to display the list of items that can be cleared.
# Select both '''Cookies''' and '''Cache'''.
# Click '''Clear Now'''.

Webmail

I think you may be confusing what Firefox is. Firefox is not an email application, it's a web browser. You can use it to access websites. Some websites are email applications.

What site are you using?

about:support

We'll need some more info about your Firefox setup. Go to '''Help > Troubleshooting Information''', then click '''Copy all to Clipboard'''. Open a reply to this post, and go to '''Edit > Paste''' to paste the info from your Troubleshooting Information page.

about:config

In the [[Location bar autocomplete|Location bar]], type '''about:config''' and press '''Enter'''.
** The about:config "''This might void your warranty!''" warning page may appear. '''Click I'll be careful, I promise!''', to continue to the about:config page.

Go to profile (before telling a user to delete a file)

Go to '''Help > Troubleshooting Information''', then click on '''Open Containing Folder'''. That will open Windows Explorer in your Firefox profile.

Update Flash

You're using an old version of the Flash plugin, which can cause problems. First update your installation of Flash. See [[Managing the Flash plugin]]
