Hi, I'm new to asking the Firefox community a question, but I hope you can give me directions to solve my problem:

I currently have Firefox v. 78.15.0esr on an iMac (early 2008) running OS 10.9.5.

I know that version has been unsupported by Mozilla for a few years, but I still want to keep this computer alive after I install the latest Firefox version to the newer (refurbished) iMac M3 2023 which should come with OS 14 or OS 15.

I hope that downloading the latest Firefox for Mac version off your website should be pretty straightforward, but what I really need help on is how to bring my Profile residing in the Library/Caches/Firefox folder on my older iMac to become my Profile on the latest Firefox version on the newer iMac (while still keeping my older iMac).

Appreciate the help.

I sync tabs with multiple devices, but I cannot get my tabs to sync with my iPad. I have tried scanning the QR code from my desktop browser. I have tried entering the password. The process never finishes on the iPad, even after the desktop browser said the process was complete.

I installed firefox on other PC and I logged in with my account. Despite having synchronization for passwords, bookmarks, etc., I can't sync my data on my new PC. Why is that?

I'm trying to get my wife's firefox browsers synced - mainly her laptop and phone. I've got the phone signed in and working fine, but on her laptop there's no option to sign in and the sync option is missing from the settings menu?

It seems to be profile related as if I create a new blank profile the option is there - but if I copy all the data from her original profile the option goes missing again. Short of manually copying all her data over, I'm a bit stuck for what to do next - any ideas?

I've tried disabling any addons, restarting in troubleshooting mode etc. I've also looked at all the other solutions I can find from here (mostly related to group policies, there's nothing enabled on this) and everything seems as it should be.

I haven't tried reinstalling, but it seems like this is a profile issue rather than an installation issue?

It's a Win 11 laptop (upgraded from W10 if that makes a difference), FF version is 135.0 64 bit.

Thanks!

Running Win11 on desktop PC. Sync option offers QR code to scan but Firefox on android does not have sync scan option on settings. Despite instructions to contrary, that option is not listed on mobile. Yes I'm logged in and yes I have synced previous versions of firefox

I set up sync, I went thru my old passwords on my Mac browser Firefox and deleted many old/dead ones, expected to see the list on my iPhone Firefox browser to match. Signed in properly on both, pressed sync several times each time showing complete.

I'm still seeing PW's I deleted on my Mac in my Iphone's list...

What could be the problem? I have uBlock Origin ad blocker installed.

Thanks

I don't know exactly which topic my question belongs in so here it is: When I change my home page on my computer in my bed room, it also changes my home page in my office. The home page in my office will not come up on my computer in my bedroom. Any help would be greatly appreciated. Thank you

How do I sign out of FF on my Iphone? When I attempt to log out of either the computer or the phone it stops sync. I want to be able to use firefox on the phone without having the computer on???!!!
