Diễn đàn hỗ trợ Firefox

Tabs to not reliably reopen after closing Firefox. The latest occurrence, but not the only one, was after updating macOS 13 on a Mac Mini M1 using current version of FireFox.

I have read multiple help pages and double and triple checked settings. My work around has been to Bookmark All Open Tabs each time I close FireFox or shutdown the Mac - doable but a nuisance.

Suggestions appreciated

Lately, far too many websites I try to open, simply won't! Sometimes it's via links from my home page, sometimes it's links within various websites, like a newspaper, or social media, just whatever, no rhyme nor reason, nor consistency. Even when I manually input the url, nothing happens, the browser just sits there, nothing happens. I've restarted, I've refreshed websites, clicked on "open in new tab/window", nothing gets it to work.

Whenever I go to a Google page (tested on Google.com Docs, Sheets, Forms) the page crashes. The issue started sometime around this afternoon.

Starting a few weeks ago, firefox would not load any accounts via https://login.microsoftonline.com/ one one of my Macs.

I was running the latest version 121.xx on MAC 12.7.2

Nothing would fix the site issue, so I tried re-installing and refreshing Firefox. Followed all the troubleshooting steps.

Now firefox is completely broken. Tried creating a new profile. Running in safe mode, etc.

It sometimes will load pages, but extremely slow. But generally is unusable.

Firefox works on my other macs just fine (Profile uses sync with those machines)

Safari and Chrome work perfectly fine. No malware. No ISP issues. No firewall.

Please advise a fix or I guess I will delete everything firefox related.

I received an email suggesting that I update my Firefox or I would lose syncing function. I have two computers. A fairly new iMac Ventura 13.6.8 running Firefox 123.0 64 bit which it says is up to date. But I also have an older iMac OSX 10.11.6 El Capiten running Firefox 78.15.0 ESR. I can't update the OS or Firefox on the old computer. So if I do nothing - will I still be able to sync on the newer Mac. I'm not too worried about the old one - I don't use it much for browsing - more for documents. Thank you. David Rimell
