I tried to delete browsing and web history when closing Firefox and this problem happened with Firefox immediately hanging up not closing except on 'force quit' and then totally not opening at all. It won't open in Safe Mode just zilch happening! Nothing I've tried has worked. I've removed and reinstalled Firefox, it but the same immediately happens. I am an older person and not a tech head! So need some simple instructions. Presently I am using Safari and but would like to get Firefox back and reinstalled again so I can access my book marks. Thanks for your help.

Oops, pressed the wrong key. To continue, Press the button in the screen shot to create a new, blank profile. This will not do anything to the current profile.

If this new profile works, then we can work on copy the old profile to the new.

Good morning, Maurpd. Looks like you have been busy.

I take it the new profile is working without problem, yes? When you are ready, we can start moving parts of your old data and Copy it to the new profile.


First; open your file browser to the New profile;

Type about:support in the address bar and press enter.

Under the page logo on the left side you will see Application Basics. Under this find Profile Folder. To it’s right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.


Second, open the file browser to the Old profile. You should see it on the directory "tree" in the first file browser. Right click on that folder and select Open In New Window.

Warning ! ! Only Copy the files you are told. We will avoid anything that might be the cause of your problems. Here is the list of files;

cookies: Do not bother. Cookies will be created when you return to the web site. However, you will have to log in everywhere.

extensions(add-ons): it would be better to download them fresh.

==============

key3.db and logins.json: These are the Passwords file.

mimeTypes.rdf: What to do with what type of file.

places: History and Bookmarks.

prefs.js: Your settings. Note, this may be contaminated.


Copy these files from the old to the new. You will get a message about the files already exist. Choose to over-write for each file.
