Hi again. You seem to have multiple (but similar issues) with your PC. The solution posted here is pretty similar to the one I posted before on another support question you asked.

"This has the potential to be a very lengthy reply. In an effort to keep it short (this issue is well documented) I will redirect you to the following link:"

I recommend that you install a decent anti-virus/anti-malware software and do a complete system scan.

If having issues browsing the internet then easiest would be to try using a second healthy computer.

Hope this helps!

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
