First, make sure the system is clean.

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.

Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.

You can download and save the full Firefox installer to an USB flash drive. You can possibly do the same with the Bitdefender application although you can also use the builtin Windows firewall and Windows Defender. You can find the full version of the current Firefox release (55.0.1) in all languages and all operating systems here:
