i got an update message and restarted firefox. now all my saved bookmarks and passwords for accounts has disappearred. how do i get them back? under settings, it doesn't give me option to import from previous firefox

Since updating Firefox from a previous version, the browser no longer displays any Unicode emoji characters. Where an emoji would normally be rendered (👁), the browser instead displays empty space. Websites such as twitter and discord, which use their own artwork for emoji, are unaffected. This has negatively affected my browsing experience.

For illustrative purposes, I will add a series of emoji and include a screenshot of how they are displayed: (😀🙁😡💀). Other characters still display correctly: (β❖♞䷲⎈𐘢𓀺இ). My computer otherwise displays emoji correctly. The issue persists after disabling extensions, and has persisted between computer restarts.

I am using Firefox version 147.0.4 (aarch64) on a Macbook Air running macOS Sequoia 15.5.

Issue Summary: When disconnecting from a corporate Cisco AnyConnect VPN on macOS, Firefox completely loses its internet connection and throws network errors. Other browsers (Chrome, Safari, Edge) continue working perfectly on the home network. Standard troubleshooting steps—like clearing Firefox's DNS cache, changing proxy settings to "No Proxy", turning off DNS over HTTPS (DoH), and flushing system DNS—do not resolve the issue.

Root Cause: Cisco AnyConnect locks low-level socket configurations and routing rules within the active Firefox user profile (prefs.js). Even after the VPN is disconnected, Firefox remains bound to the dead corporate pipeline, a behavior that standard settings menus cannot override.

Proven Solution: The only way to clear the corrupt VPN socket locks is to completely reset the internal profile architecture:Open Firefox, type about:support into the address bar, and press Enter.Look at the top right of the page and click the "Refresh Firefox..." button. Accept the prompt. Firefox will close, securely back up your bookmarks/passwords, generate a fresh profile, and restart.Internet access will instantly return to normal. (Note: You will just need to reinstall your extensions afterward).

I have always, for 15+ years, been able to use the system Print dialog box to create a PDF.

But as of updating Firefox to version 152.0 (aarch64), all buttons related to Saving a PDF, etc. send the document straight to the Printer to print a hard copy. There no longer appears to be any way to save a PDF.

Example scenario: 1.) Visit website 2.) Select Print (cmd-P, File > Print) and open the 1st print dialog box 3.) Select "Print using the system dialog..." 4.) Select PDF in the 2nd dialog box. 5.) You used to be able to save the PDF at this stage, opening Finder, naming the file, and choose the Save DIR. However, as of this latest update, even after the Finder File Name dialog box, hitting Save at that stage sends it to the printer to print a hard copy.

Pressing PDF, Save as PDF, Open in Preview, and Save as Adobe PDF all send the file directly to the Printer to save it.

I've got tons of receipts and things to save for work in PDF and FF was always great at this. What happened? Is this a feature or a bug? Any and all advice is welcomed.

Running macOS 26.5.1, M2 Pro, macbook pro.

After last auto upgrade of firefox browser, my print function is dysfunctional. When I try to print a broker data page, 2 "boxes" of options on the page I'm trying to print, become open, with long lists of all possible options, when they only show the one option I am using on the real web page I'm using. This takes up 1/2 of the printed page, and moves the data I'm trying to print down so far that I have to print 2 pages to include it all. This is a change which did not occur when printing before the upgrade. If I switch to a safari browser, this does not happen (but I prefer the firefox browser). Help please.

Hi, a while ago something changed in my Firefox where when browsing and refreshing a page it now returns to the top of the page. It always use to refresh to the same place on the page so i didn't need to scroll to get back to where i was. Does anyone know how to fix this? Any help greatly appreciated. Thanks

I created a new profile on my account. Whenever I am in the original profile, I can click on the new profile and it will open a new window with a new icon. However, I notice that under the new profile, it is not signed in. When I try to sign in, I get an error that says

Account already in use xxx@gmail.com is already signed in to the “original” profile

You can only associate this account with one profile on this computer.

Then it forces me to switch back to the original profile. This tells me that the profile is not syncing for access across devices.

This is happening on my macbook.

I do NOT want to use ANY VPN services. Since you introduced this, or rather, forced it on me, my browsing experience has been terrible. How do I turn off VPN? There is no VPN icon on my topolbar despite what your instructions say.

What are the step-to-step instructions in order to use Free VPN? (see attached image) I did a query on the web and it came back stating that Firefox VPN was not free. I am confused. Thank you for your prompt assistance.

My mac froze, force quit did not work, unplugged it, turned it back on, all bookmarks were gone and not able to add new ones. Would like to restore old bookmarks and add new ones.
