slow browser takes long time to change screens & i have hi speed inernet & side skrool bar works half the time &stay loged in dont work makes you log in evertime fix website

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

I have scoured the web and read/tried everything. I cannot remove the time and date stamp from my documents. No matter what program/app they are printed from it shows up ruining my printing. I've tried unchecking the header/footer box. There's nothing in my brother printer set up regarding the date/time stamp. It has to be firefox. How do I fix this? I'm not a computer guru so I need details. I'm at my whits end! 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?

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 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
