Window 7: Can not set Firefox as a default application
This morning Firefox upgraded its self. Since then I've not been able to click on links in e-mail to open up web pages. Every time I manually launch Firefox it asks me if I want to make make it my default browser. I reply Yes, so it asks me which account (my or the Administrator) I want to use. It does not appear to make any difference as Firefox does not become my default browser.
In increasing levels of desperation I've tried:
- Tools | Options | Make Default
- Rebooting the PC
- Deleting my Firefox Profile
- Reinstalling the latest version of Firefox
- Reinstalling an old version of Firefox
No luck. Following other threads in this forum I've selected Start -> Control Panel -> Default Programs -> Set Default programs
Firefox is not listed.
How to I make Firefox my default browser?

Let’s do a full clean re-install;
Save the file. Then Close Firefox.
Using your file browser, open the Programs Folder on your computer.
Windows: C:\Program Files C:\Program Files (x86)
Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux
If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.
Do Not remove any profile folders.
After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

I do have a C:\Program Files (x86)\Mozilla Firefox directory, but it contains almost nothing. For some reason Firefox has installed it's self at: C:\Users\<user-name>\AppData\Local\Mozilla Firefox
Should I delete this directory instead?
Yes. Remove any Firefox or Mozilla folders. BUT, do not remove the profile folders.
These should be under; C:\Users\=<user name>=\ AppData\Roaming\Mozilla\Firefox\Profiles
I've tried all of that but no luck - Firefox will not make it's self my default web browser application. The Windows Control panel will not update to include Firefox as an application that can be defaulted
I called for more help.
Thank you. I'd appreciate all the help I can get resolving this
stormcloud, start from the begining. Launch cmd as admin, type: sfc /scannow and press enter. Wait for finish and tell about result to us.

As requested, I've run the scan. The results are:
C:\WINDOWS\system32> sfc /scannow
Beginning system scan. This process will take some time.
Beginning verification phase of system scan. Verification 100% complete.
Windows Resource Protection did not find any integrity violations.
stormcloud https://support.mozilla.org/ru/kb/kak-sdelat-firefox-brauzerom-po-umolchaniyu Didn't work?
Firefox still isn't registered as a default program, but the scan show no other problems on my machine
@FredMcD, Any news from the people you asked?
I called again.
From what I understand, the default browser needs to be set from the Administrator's account on Windows 7.
A few suggested solutions:
- Start with the 3 Horizontal Bar Menu(sometimes called the Hamburger) in Firefox - then >Options>General>"Always check if Firefox is your default browser"
- Originally I found this thread as it seems to have been an issue starting in 57 here
- Are there any pending updates to your version of Windows? I would suggest making an update.
- Is Firefox listed in this menu of default programs? illustrated here
- You already ran a malware scan, do you have any other antiviruses installed on your computer? Temporarily disable these from the administrator's account to see if this is the cause.
Two more questions if you don't mind.
- What version did you upgrade Firefox from, and did you use an installer or the update Firefox prompt?
- Have you updated to Firefox 60?

In answer to your questions:
> Start with the 3 Horizontal Bar Menu(sometimes called the Hamburger) in Firefox - then >Options>General>"Always check if Firefox is your default browser"
This was the first thing I tried - but it didn't help.
I'm running Firefox version 60.0.1 (64 bit)
I am using Windows 7 With service pack 1 installed and all of the latest OS updates. My PC regularly virus scanned and checked for Malware, so I'm as confident as I can be that there are no issues there.
The link you sent is for question 1207775 applies to Windows 10. I didn't see anything similar for Windows 7.
I've just upgraded to 60.0.2 (64-bit), but it has not helped
Hi, I think everyone has done what they can for you here. I think it is now time to hand this off to a Windows 7 forum to help you further since it seems it is not Firefox as the problem but is a Windows 7 hiccup.
Please try one of these respected sites and refer ti this posting so they know what we have tried https://support.mozilla.org/en-US/questions/1218097 :
Let us know what transpires. All above are good people/places.
Thanks for the time you've spent trying to help. If i find out what the problem was I'll update this thread.
