Stop Firefox from opening at restart

OK, Drew, I went through all of yours to no available, but I will list each as I went through them in case I've done one or more incorrectly.

Only Login Items I have and have had for many, many months are CrashPlan menu bar and 1Password 6, which I've only had for less than two months. See image attached...

When FF opens, it opens in the "Safe finder" window. See image attached...

It does show the homepage ID'd in preferences when opening. See attached image of same...

I did try resetting/ refreshing FF. First time restart it did not open, but next time it did.

I have no FF extensions, nor have I ever had same. I use FF as little as I can; only when necessary.

I downloaded Malwarebytes, but I could not get it to run.

I have not yet created a new user account; I missed this one in your list. I will now try my guest account to see if it fails in the same manner and let you know.

I did a safe boot with no success. While I was in safe boot FF did not open, but when I went back to my standard account, it did.

Thanks for your effort. I'll now try the alternative guest account and let you know results. —NeilKo

Hi Drew

I've been seeking to clean up my Mini as much as possible along the way. I am quite frustrated by the "Swap Used problem." The place I see "Beachballing" the most is when I open or go to use Excel, which I use every day. It is extremely slow to open. Also, I noticed that my Boom 2 seems to take up a disproportionate amount of RAM, so I'm now keeping it closed on a regular basis, although even though it is closed, it still shows up in my etrecheck report; I just did another run, hoping that it might tell you something new about what my system looks like now that it has been a couple of weeks since the last run...

I have the full run saved, should you want to see it.

Finally, last but not least, as I was going through the paces guided by you, I realized that the opening Sierra Mountains that I have is not "normal," i.e., mine is heavily blurred — see attached below. When I went to my guest sign in, I noticed that it is nicely crisp as it should be, and I wonder if there is still an anomaly in my system that is causing it.

As always, I appreciate any guidance you may have for me.

I just downloaded and ran Malwarebytes for Mac. My mistake earlier was that I downloaded the Windows version. I had 97 suspected files all of which I deleted and restarted. I'm hoping I'm now good to go. I did the same thing with my MBA, as it is on the same network, and I had about 45 threat files there.

I've now downloaded Etrecheck to run it. I've now run it, but I have no idea how to read it, so please advise if you see other things I might do to clean up my system; here are the results...

Thanks for giving it a go. I've checked Login Items on several occasions to ensure that Firefox is not a login item. Also, whenever I start up and Firefox is open, I immediately close it, i.e., it is not open when I shut down or restart. There has to be something else going on. Thanks, again, though. —Neil

I tried this before going to Drew's many suggestions. I thought it would be the easiest if it worked, plus I've been looking for an app like Easy Find for a year, so either way I would win. I downloaded Easy Find and searched for any and all citations for firefox and got a dozen or so. I deleted all of them thinking that would surely block it out from opening again. No cigar — FF opened the first time I tried. Nuts. I then moved on to Drew's many suggestions — See my response next.

I just tried an alternative user account, and it opened without FF showing. I then logged out and in without the box checked for opening windows AND IT WORKED!! — SO FAR, ANYWAY! I'm a bit gunshy given what I've had to go through to get here, but at this moment, i.e., the last login, it stayed away. Now I'll have to try it on a restart basis, which might be different login/out.

Sadly, when I tried it on restart, FF showed up again — not unlike gum stuck to my shoe! I'm going to try Easy Find again, per Kappy's suggestions, but I have to leave it now. Thanks to you both for all of your efforts.

Thanks to all who have offered suggestions. I finally threw in the towel and removed FF from my desktop completely. I also used Easy Find on both "firefox" and Mozilla" to delete all references to same. I've spent more time trying to fix it than I've spent on it in the last five years, so I thought it was time to pull the plug. If I should happen to need it again, I can always download it for free :-) I sincerely appreciate all who have tried to help. Thanks, again.
