how to completely uninstall mozilla firefox

So I've been using Chrome and Chromium for last month. I've been to busy (until now) to deal with this further. Sorry I don't remember all the details about the offending addin. My Firefox preferences (and I think maybe addins too) were still present from the prior installation of Firefox. So then I uninstalled Firefox, rebooted, then reinstalled Firefox.

I uninstalled it, but Firefox behaved like that addin was still present. I soon became suspicious that the addin might be malware or spyware. I forgot the name of the addin because this happened a month ago. Recently I installed some addin or app (whatever they're called) into Firefox. (I need the various browsers to check websites that I administrate and sometimes do web design on.) I was a happy Firefox, Chrome, and Chromium user with Linux Mint Sarah 18. Latest version of Firefox, whatever that is.

I suspect this may require working in terminal. I'm not sure if I'm still a newbie or maybe intermediate.

Switched to Linux Mint a few years ago and love it. After that I can do a fresh install and be confident it's not compromised by a rogue addin.īackground Info and Details (The details - for those who want to know the minutia) Please tell me how to completely uninstall Firefox using command line, including I want to erase/delete all preferences and addins.
