I have two users on my home pc but one has a "hammer" icon next to the help in the menu bar and its not even english! help
Ok, again I have tried to download several time the new version of firefox and with my wife as administrator she has a little icon like a hammer and when i open its a game but not english but on my user page i downloaded the same new firefox but don't have this icon does this mean she has a problem with her user interface
I'm going to suggest a new Firefox profile in your wife's Windows profile. The following is a little long, but not difficult if you go step by step.
First, I recommend backing up your wife's Firefox settings in case something goes wrong. See Backing up your information. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, with all Firefox windows closed, start up in the profile manager and create a new (blank) profile: Managing profiles.
Hopefully this one will be "hammer free" on first run and after closing down Firefox and restarting it in the new profile again. If so, the problem may have been one of your wife's add-ons. You have the choice to keep the problem profile and disable all non-essential add-ons, or migrate key settings to the new profile.
To move key settings like bookmarks from your damaged profile to the new profile, see: Recovering important data from an old profile.
If the new profile also has the hammer, it could be created by an add-on in a separate folder. Please open Help > Troubleshooting Information and copy/paste the extensions and plugins in your reply.
Note: after using the profile manager, Firefox generally keeps using the last selected profile. To switch, close Firefox and use the profile manager again.
