Diễn đàn hỗ trợ Firefox

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've noticed that Firefox has been running very slowly on my computer recently. Pages take a long time to load, and the browser often freezes or becomes unresponsive. I've already tried clearing the cache and disabling extensions, but the problem persists. I'm using the latest version of Firefox on Windows 10. Are there any other troubleshooting steps I can take to improve performance for my website?

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 ?
