My Firefox on Mac crashed after message to quarantine Ransomware. Reinstalled v75, now working but only opens with Profile Manager using terminal command.

Out of the blue I received a message stating I was being attacked on my Mac by software that maybe Ransomware. I was asked to close and delete the files.

I run Mac Os 10.14.6 and have never had any previous problems. After quarantining these files I quit Firefox and then could not open it. I therefore deleted the .app and reinstalled Firefox 75. I can only start up Firefox by using the Terminal Command window using the Profile manager. I created a new profile but cannot see my old profile within the Profile Manager. I can find the old profile under Profile's in Application Support/Users. So despite having a new default set created, I still cannot get the Firefox.app to open by clicking on it. I have now deleted the old profile and still cannot open the Firefox app from the dock or applications folder.

help please!

I could never find out why I got the message "Ransomware may be trying to access my computer", except two files have appeared in my bin; Edgar Poe Murder and Righteous Games.

Any help appreciated.

Chosen solution

Hi I think I may have found a solution. I had both the Firewall on for my Mac and Vault encryption. When I added Firefox to the Firewall settings and then turned off Vault Encryption I could open the program but with the following message. So now I can open Firefox from the Dock but the. app does not seem to be in the Applications Folder. A bit strange.

Hopefully it will work as I have synced my settings

Let's make sure your system is clean.

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Thank you Fred for your help. I have run the Malware software and also I have Intego Virus protection and all have scanned negative. I still cannot open the Firefox app, other than through the Profile Manager. I note that Apple's protection system, System Integrity Protection, prevents certain applications reaching the root directory eg , user libraries and wondered if that could be related to Firefox not starting up?

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.


Download Firefox For All languages And Systems {web link}

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) Note: Check Both Folders

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.

Hi Fred thanks for your patience. I have undertaken all the tasks listed above.

ie, downloaded (again) Firefox 75, removed Firefox app from Applications folder, left one and only profile, looked for other Firefox.app programs, then re installed in normal and then safe mode. The same message comes up, a picture of which I have attached. I could only start up the app using the profile manager using the Terminal window. I tried using a new profile with no success. I have attached a picture of the file directory where the profile is kept.

I am sorry to be difficult

Chris

Did it work?

If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.

Yes it appears to have worked.

That was very good work. Well Done.
