Uninstalling Firefox

Leave the frameworks alone. They're part of the OS.

See discussion here: https://forums.macrumors.com/threads/leftover-mozilla-files-after-deleting-firef ox.2003582/

And Mozilla uninstall instructions here: https://thread/7968089

All should have been left alone. You should not be removing anything manually from the System Folder. You may or may not (probably not) suffer any effects from this. A reinstall over the existing OS with a full installer will fix it if you do.

In the future, use application uninstaller if available, or google how to completely remove an application.

I agree with what Glenn Leblanc posted.

Whatever the reason, the uninstall link I posted earlier is broken:

If this one doesn't work, it's easy enough to find using a search engine.

I'd be very careful with that. Nearly all Google search results will be for garbage products and scams that are certain to contain malware of various descriptions, or be malware in and of themselves.

To uninstall a product, follow its documentation.

You're right John. That could produce a wide variety of results. Should have made it clear to search for an uninstaller made by the same company as the application, or manuel instructions from the company's website on how to completely remove an application.. Not all products provide instructions on how to remove their application, and few tell you how to completely remove their application and all files associated with it.

No 3rd party uninstaller or cleaner programs.

So true John. I have found myself the victim so many times on clicking on something I thought was the correct link only to find my cursor on another link to install McKeeper or some other garbage, or at the provide password to install. And I try to pay attention to these things and still get caught by the disguises. One must pay attention to everything today.

Thanks Glenn. The Internet is a vast wasteland of scams, and Google is its tour guide.
