‘My original Firefox browser will no longer open, so downloaded and installed new one. Is there a way to get my passwords and history. It was the browser that I had my email deliver to.’ I was able to download from my other browsers, but the Firefox one just won't open.

Hello, I just recently restarted my computer. After I did, Firefox asked me to sign in again. I did, but now I'm on a new account without any of my other profiles. This happened once before and I was able to get my old account back, but I forgot how I was able to do that. How can I sign back into my old account?

I have a user who is using an imac late 2012. When the user installs firefox release version 100. Firefox will open but will not go to any websites. All other web browsers work just fine but for some reason Firefox will not sync and will not open websites.

I wanted to adjust some system preferences after installing the new FF 100 OS. Found I can't, either by menu or by keyboard shortcut. How do I get my access back? Using Mac OS 10.13.6. Do I need to go back to previous FF 99 version?

Thank you Rob

I am on an iMac running High Sierra 10.13.6. For the last couple months whenever I try to close Firefox it either crashes or I have to force quit Firefox to make it quit. But on restart tabs have been restored, or I have been able to bring them back using "restore tabs".

Two days ago my wife was using my computer (I was out of town) and when she finished she tried to turn off the computer. She got a message that Firefox was not closing so the computer could not shut down, then a minute later (without her doing anything) the computer did shut down.

I got home todaty and started the computer. Opened Firefox and found all of my saved/open tabs (~25) were gone. No "restore tabs" option available.

Is there any way I can locate and restore the missing tabs? I've looked through some posts in Support, but all of the crash issues I found were of a different type. And it would also be really nice if I can get Firefox to close normally again. Are there any plugins that commonly cause this kind of problem?

Thanks in advance for any help!

How to fix this? Found it previously on Windows 10 but was fixed with the next update to Firefox on the Windows 10 machine. Just updated Firefox on the iMac to version 92 but problem remains.

I am on Mac OS 10.13.6 and I cannot open Firefox and it says Profile Missing, and will not open. I don't care about any bookmarks or anything I just want to use Firefox as an alternative browser to Safari.

How do I get Firefox to recognize the profile that is in my Library on a Mac? I didn't touch it; did nothing to it, but when I tried to open Firefox it suddenly was missing. And your Help system HAS WAY TOO MUCH INFORMATION IT SO AS TO BE NOTHING BUT CONFUSING. I AM NOT A CODE JOCK OR A WEB DEVELOPER OR SOMETHING. END RESULT: YOUR HELP SYSTEM IS USELESS!!!!!!!! I even tried deleting my current Firefox and downloading a fresh app. SAME THING! Please answer back with a REAL person, not some canned menu of HUNDREDS OF OPTIONS. Or, I will simply not touch anything from Mozilla again. Now that is SIMPLICITY!!!!

Having installed Firefox on my MPB it functions well and I want to kept. However, every time I close my computer I have to reinstall my Firefox. Is that normal? The Firefox is in downloaded files and not difficult to find, but every time I want to use it I have to reinstall./ Björn
