Hi, I am having similar problem to other people that I have found on this forum in that on my computer, when Firefox is first installed from fresh, Windows 7 displays the correct icon for htm/html files, but when I restart, these icons are replaced with the generic "I don't know" icons. So far I have tried to fixes this issue with the following methods to fox this issue, none of which have worked:

- rebuilding the icon cache by deleting iconcache.db

- setting defaults programs from Firefox to IE then back to Firefox

- adding the registry keys Old Icon -> FirefoxHTML -> DefaultIcon from HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{42042206-2D85-11D3-8CFF-005004838597} to HKEY_CLASSES_ROOT\CLSID\{42042206-2D85-11D3-8CFF-005004838597}

- changing the Windows Zoom settings from 100% to 150% and back

- Using the programs Types, to delete and recreate the htm associations.

Also, I know that I have been able to fix this issue before when I have had to reinstall Windows before, but I cannot remember how exactly, aprt from that I did involve editing the registry, but possible not in the way I found on the forum.

I may of found the solution to this problem on another website, but I am not sure if it has to be done in conjunction with any of these other 'fixes'. To get the htm/html icon to display properly, I navigated to the following location in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\FirefoxHTML\ShellEx

and deleted the IconHandler key, then reloaded explorer.

Steve1951 at http://windowssecrets.com/forums/showthread.php/135115-Icons-for-Firefox-missing-in-Windows-Explorer. Found the solution which worked for me. See his quote below:

Here is what I did to fix the problem:

1. I deleted registry key HKEY_CLASSES_ROOT\FirefoxHTML\ShellEx\IconHandler (I completely deleted the key, not just set it to no value).

2. I set registry key to HKEY_CURRENT_USER\Software\Classes\FirefoxHTML\Def aultIcon to C:\Program Files (x86)\Mozilla Firefox\firefox.exe,1

3. I changed the file association from Firefox to Internet Explorer and then from Internet Explorer back to Firefox [ I logged off and on again so that the registry changes would take effect].

Now all is functioning properly.

Thanks Steve1951 this totally fixed my problem Randy

I had this problem too in FF3 (3.6.17 but I think it started with an earlier version). Deleting the icon cache didn't work, and I didn't want to change anything in the registry myself, but I found that it was solved by uninstalling and reinstalling, as follows:

First, take a backup of everything using MozBackup. Then uninstall FF3, selecting the option to completely remove personal settings. (At this point I looked in the registry, and the keys mentioned above were no longer there.) Then reinstall FF3, but without creating a new profile. Close it, and restore the old profile with MozBackup. After this the file icons were as they used to be.

One thing to bear in mind: the profile in the new installation has a different name (the seemingly random sequence of letters and/or numbers) from the old one, so if you have any backup programs etc which refer to it you might need to change their settings.

After this I actually upgraded immediately to FF4, and the icons stayed as they should be. It might have been possible to simply install v.4 without putting v.3 on again, but in my case, one of my add-ons (a viewer for the family history site Ancestry) apparently can't be installed from v.4, but will continue to work if it was in v.3 which is then upgraded.

In case anyone is wondering, I had first tried upgrading FF3 with wrong icons directly to FF4, but this didn't solve the problem. It was only the uninstall/reinstall that worked.

Hope this helps others who don't like changing the registry!
