Firefox Community Forum

The "restore previous session" function stopped working today. My privacy and security sessions are set to REMEMBER HISTORY. I have restarted my Mac. I have the latest version of Firefox. Why does it no longer work?

FF is my default browser. My computer is a new iMac (M3) desktop. I have used FF for several years without incident, until today. It opened normally, and then the familiar update pop-up said an update was available and invited me to re-start the browser. That requires providing admin credentials to the "Install the 'Helper tool' " pop-up, which I have done every time without incident, until today. A follow-on pop-up then asked if I wanted to allow Firefox to access other apps and devices, which I had never seen before. I said "No", and that was the end of my FF browsing experience. Every time I try to start the FF browser, it wants me to try to install the Helper tool; I provide admin creds, it goes away (fails), and the browser never starts.

I have a lot of bookmarked URLs and other browser-related data that are extremely important, and I cannot afford to lose them. Used Safari & Google & Mozilla helped me learn the location of the FF "Profile" folder. Navigated there and copied/pasted it (ends in ".default-release") to my "Documents" folder as a back-up copy. Downloaded a new instance of FF from Mozilla download page. Didn't open. Went to download folder, clicked the .dmg file, which opened a small pop-up. Followed the instructions to hold down the CTRL key while clicking "Eject Firefox". Nothing productive happened (no new FF icon). The old icon in the dock still doesn't start the app.

Would it be useful at this point to un-install Firefox (in Applications) and then try again to download a new version? If so, I would need help on how to make the old Profile folder (the back-up copy) available to the new instance.

Thank you very much.

I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

I got a password manager app but ended up uninstalling it. In the process, the normal insertion of my user name and password on accounts I use no longer happened. The information is still in my password file on my iMac, but when I access, for example, my bank, I have to enter my user name and password by hand. Before I tried the password manager (Roboform), there was no problem.

I've been on the phone to Apple support and just returned from the local Apple store and genius bar. My Mac Pro laptop was too old and would not support the newer OS. In installing a OS, I lost my bookmarks and the menu bar that gave easy access. I've since purchased a new Apple Air laptop and everything from the old laptop has been migrated over.

However, working with Apple support and the local genius bar Apple store rep., nobody has been able to help me rebuild the links to a menu bar for quick access. Presently I have some bookmarked. I have to go to the book marks to access any particular URL. All the directions on the web have not provided way to do this!

Hello:

I have a new MacBook Air with the M3 chip. I cannot login to my Costco account on this Mac. I can log in using my old MacBook and my iPhone. I am using the same settings as the ones on my old Mac. What seems to be the problem? Is it the new chip?

Regards,

Moe

There are reports of conflicts between Firefox performance and Sequoia, how to resolve it? I would like to update from my current MacOS and I‘m not willing to give up Firefox as my primary browser. Could I get advice when it‘s save to update? Best regards RB

Sometimes, when I copy and paste a Youtube link into Firefox or I open a Youtube video in a new tab, the video player won't load. Sometimes it's fixed when I reload the page, other times it can only be fixed if I open a new Youtube tab and paste the name of the youtube video in.

Notes: - Tested in privacy browser with only Ublock origin active (no other extensions), did not appear to have this problem (It's a bit difficult to test since it only comes up sometimes with opening Youtube in background tabs/copying and pasting a youtube video)

    - Something I noticed: video player appears to load a lot faster in privacy browser.
    - However, turned off all extensions and themes in non-privacy browser and still had the issue
    - Youtube pages load in the background of privacy browser, but in the normal browser I have to click on them to load

- Turned off hardware acceleration, didn't change anything - Tried troubleshoot mode, doesn't look like the issue is still there? But confused on why the issue still happens when I turn all extensions off not in troubleshoot mode

Wondering if it's an about:config issue? I don't think I changed anything in there, though.

Screenshot of my issue below.

Multi-Account Tab is on longer loading. I uninstalled it, shutdown my computer, and restarted it, reloaded it back on. Unfortunately, it's still not working. I do have Tab Stash on my computer as well, and it not working either. I guess the two problems are related, but I thought I would start with Multi-Account because I didn't want to lose all my bookmarks.

Does anyone have any thoughts on how it fit this?

Thanks,

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

Firefox, when moved, opens in full screen. I've seen the info about hovering over the green button and choosing the correct mode, which doesn't seem to exist. There also seems a key command of Command-Control- (something), that doesn't work. Both of these strategies cause the problem to occur, again. Help? I'm on 132.02/Mac Sequoia.

I have a MacMini M2 with the current Sonoma os. Firefox has been updated. Frustrating. Yet prime videos won't play and get this notice:

"Mozilla Firefox update required A later version of Mozilla Firefox is required for Prime Video. To update, click the menu button (three horizontal stripes) on the web browser toolbar, click Help, About Firefox, and then click Restart to update Firefox."

When I click on Firefox, the top menu bar is dimmed. When I click on New Tab or New Window, nothing happens. I've downloaded, reinstalled and updated the latest version of Firefox but it doesn't work. I've also clicked Option when opening Firefox. I click Refresh Firefox and it works but when I quit and restart, I'm back to the same problem again.

Yesterday I could open any or all of the downloaded apps on the screen of my Apple laptop. Today, I can't! WHAT IS GOING ON? Being elderly and not very techie (to say the least!), I need simple answers, no jargon please. Is it because my laptop is 'elderly' in tech terms (Catalina 10.15.7) or what? I've used Mozilla most of the time for very many years, but I might swap to Safari or Chrome instead if this isn't sorted out PDQ.

since updating to 132, internet access has deteriorated; frequently having to switch off wifi and switch on again; using macOS Monterey, Version 12.7.6 Regards, John

I have a 2012 MacBook Pro, still using maverick's … I tried to upgrade Mozilla and now it doesn’t work.

I am shy of what’s needed to run the latest Firefox version and I’m not able to buy a newer laptop, how can I get restated again with the version that will still work on my MacBook ?.

While my laptop was "aseep" something happened to your service. I was kicked off and told to resign in. I did not remember my password. I was cautioned that my data might be lost. What the hell happened?
