Diễn đàn hỗ trợ Firefox

I've had recent security issues and have had a couple actual breaches. Having two accounts so similar to one another caused some unnecessary confusion during a panicked burst of changing passwords. Can we merge them?

I can't sign into my TracFone account on FireFox or FireFox Private Window. But I "can" sign on in Chrome. Is there someway to fix this as FireFox is my main default browser.

Thanks in advance for any advice

Long ago I used to never have to hit F5 to see today's version of a page instead of the cached version, and I do NOT want to clear cache or cookies or history on exit, no, that's not the setting I'm looking for, thanks.

I've noticed that when logging into various websites, a random email address not known to me appears in autofill among my usual email addresses. This unfamiliar address is under the @shanreto.com domain and shows up across different websites. My Firefox account is synced between my PC and mobile phone. Both devices are password-protected and under my control at all times, and I have only installed uBlock Origin as an extension.

Could there be any explanation other than the possibility of someone accessing one of my devices through malicious software or similar means?

I am trying to get to the "clear cookies and Caches" which should be under Privacy & Security.

When I go to preferences, i can move to Privacy & Security or the other headings, but I cannot scroll down any of the pages under the headings. When I am on the Privacy & Security page the scroll down arrow takes me to Sync heading etc.

How do I fix this? I am having to go to the cookies to clean up as I am having another scroll down issue with an app that is important to me. In that I cannot scroll down a list as the dark side bar flicks on and off immediately.

I am on a MacBook Air.
