Firefox 技術支援討論區

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!

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?

Every time I open Firefox, my open windows open, as they should, except the front tabs in as many as half of windows get stuck trying to open! The screen is blank, and you can see the spinning wheel in the tab window above the toolbar. Usually, if I click to stop it, then hit the refresh button, it will finally load the tab. Why can't they all just load, for while they don't, FF will still run up nearly all my RAM, maybe trying to load takes more juice. I don't know, but it's not supposed to be doing this. Opening tabs if a pretty fundamental function of any browser...

Dear Community, I love Firefox but here is how fonts now look like on my old MacBook Pro (v10.13.6). Why is this? How can I fix this? My Firefox version is up-to-date. As shown on the screenshots below, on Chrome fonts appear to be normal. Thanks so much for your guidance!

/moved thread from Firefox for iOS (for iPhone/iPad) to (desktop) Firefox section.

‘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.

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 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.
