Diễn đàn hỗ trợ Firefox

I went to a local website and ended up getting virus warnings, see photo. I doubt if it's real but I don't know how to get rid of the messages, or scan for the virus? I scanned with the Windows virus protection and the computer came back clean. I can and have turned the computer off and back on, no help.

Thanks

Hello, once every morning I start 14 tabbed Internet pages. The pages do not fully render unless they are in focus. Is there an About:Config or other setting where I can get all 14 pages to fully and completely render without getting each one into focus one by one?

This is a very slow process and is annoying over time. I believe there was a time where Firefox would render all tabs/pages without getting each one into focus.

Thanks in Advance.
