Windows 10: defender working with firefox browser

i w ould like to find out if windows defender works well with firefox browser

:)

 

a problem with firefox been the default browser

No I don't remember seeing it before installing Waterfox. Also, I tried uninstalling both Firefox and Waterfox and then installed Firefox, still not present on the Default Browser list.

Windows 10 1809 with the latest updates but the same problem was there in 1803. I didn't notice it before then.

I tried the suggestions in the link you provided and nothing worked except the last one with the command prompt command. That worked on the laptop that was most affected and made Firefox appear on the list and is now my default browser.

I also have a desktop which has had Firefox as the default browser forever but it doesn't show up on the Default Browser list and none of the suggestions worked to make it appear. I'm not going to mess with that one too much as Firefox is already the default browser so I'll be fine unless it somehow gets changed.

Thanks for your help.

 

Unresponsive script error in Firefox browser

Hello Thomas,

Thank you for posting in Microsoft Community.

I understand the inconvenience you are facing in Firefox browser. We will help you.

• Are you facing the same issue in Microsoft Edge and Internet Explorer?
• Did you try deleting the browsing history and clearing the cache and check if the issue resolves?

If it works fine in Internet explorer and Microsoft Edge and not in Firefox, I suggest you to
uninstall the Firefox application and reinstall it and check if the issue persists.

• Press Windows + X keys and select Programs and features.
• Select the Firefox app and click Uninstall.
• Restart the machine and reinstall the Firefox and check if the issue persists.

Keep us posted to help you better.

 

How do I make Firefox my default browser on a Windows 10 laptop

Step 5 is incorrect; when I go to choose an app, the only choices are Edge, IE, or Chrome; Firefox is not listed.
