Diễn đàn hỗ trợ Firefox

I've tried going in safe mode, turning of my Facebook container. Deleting cache. Signing out of Facebook. Also adjusting the backspace key in my Config. Having no problems on my Android phone or when using Opera. It's on on Firefox and on Facebook.

FACEBOOK screen suddenly moves to the bottom of the screen when I am typing a comment. Whenever I hit SHIFT+alpha_letter at the beginning of a line OR simply hit the backspace key, the screen suddenly shifts to the very bottom of the page again even if I have tried to scroll the page back up to the middle of the screen manually. This shifts the entry area where I'm typing down and sometimes off of the visible screen entirely. Just hitting the backspace to correct a typo causes the screen to scroll on its own. I have to scroll back down to the entry box and if I make another typo, it happens again. 

Please help. Been going on for over two weeks. I was hoping the new Firefox update yesterday would help. Nope. Still happening.

Since the latest Firefox, I cannot load Bell Webmail when I am using my VPN. Everything works fine with Edge. I am not tech savvy, but is there something in "settings" that should be adjusted. Bell says that Firefox is the problem. Alan

mazdausa.com won't fully display. I just updated to version 100 (woohoo) and tried looking in troubleshooting mode, still no luck. The middle of the page where the car (picture) is supposed to show up is blank. The rest of the site loads.

Yesterday I started having trouble logging into Gmail and associated apps (calendar, contacts, docs, sheets, shared folders, etc., as well as google.com) in Firefox. All other sites are loading with no problems. Google apps are working fine in Chrome. Still having problems today.

My office uses Google Workplace for everything so this is really messing me up, I've lost several hours of work trying to get things to load. The IT person told me that if Firefox is having problems I should use Chrome instead. I hate Chrome! I want to use Firefox, but I can't get my work done if it won't load Google apps.

Please note that I have tried the following solutions thus far: restarted Firefox (several times) restarted computer removed add-ons cleared cached web content cleared cookies and site data refreshed Firefox solution at https://support.mozilla.org/en-US/questions/1200943 solution at https://support.mozilla.org/en-US/questions/1132284 solution at https://knowtechie.com/is-mozilla-firefox-not-loading-pages-for-you-heres-the-fix/

After each fix things start working for a while but then everything Gmail-related freezes or crashes and I need to start all over again. Help!!!

I have been trying to get on the Malwarebytes website, but I keep getting;

Your connection is not secure

The owner of links.malwarebytes.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

links.malwarebytes.com uses an invalid security certificate. The certificate is only valid for the following names: *.fortinet.com, fortinet.com Error code: SSL_ERROR_BAD_CERT_DOMAIN

This happens with all of my web browsers. Is it safe to allow Fortinet ?
