I-Firefox Community Forum

My computer displays were dramatically different one morning a couple of days ago, as MS Edge seems to have overtaken control of my system, which included changing the displays on my monitors. I have restored the system to a few days ago when the system was correct, but the restore resulted in the same Edge displays. With considerable effort to overcome Edge, I have also made Firefox my default browser. After resetting and restarting, my One Note pages are still no longer available and my displays have not changed from the Edge-changed ones. Any additional ideas? Please?

I am looking for a solution that will allow links to open in the same tab rather than tab, tab, tab, tab, tab, tab, tab. I am also having issue with sign ins opening a new blank tab and not having the ability to sign in at all. I've been using Firefox since I quit Netscape. And yes, I tried many epic fails that were disguised as solutions that don't work. I'm seriously about to give up on this browser if I can't get what I had after a SSD drive fail that forced me to reinstall from the ground up.

This page (https://store.creality.com/products/creality-k2-plus-combo-3d-printer?official-website-pro-store%3FOfficial-website-index-buy=&spm=..index.index_creality_product_1.1) appears almost white except for two small buttons in firefox but is normal in Edge. Note that it's same in troubleshoot mode.

Please help me. Firefox disappears when I open a second app on top of it (i.e. MS Word or Mac Mail). Full screen is not selected. If I put Firefox in split screen (which is not what I want), there is no option to open a second app in other half of screen.

I'm using MacOS Ventura 13.7.4
