Upgrade my desktop Firefox browser to version 126.0.1 a few days ago. Since then, I'm having all kinds of probs logging in to social media sites. The biggest prob is with X. I've tried to inquire about this situation with X support. I'm being told that my account is good and I should not be having log-in probs. When I explain that I'm being given an authentication challenge that is not allowing me in - despite the fact that the challenge is cleared - I'm told that I should consider my browser privacy settings. Nothing has changed with this since my last log-ins except the upgrade for Firefox. Please advise regarding this inquiry: is there something new in the privacy issues with this new upgrade? And how can this issue be resolved? I've attached three screenshots to illustrate the prob. Thanks.
