> You actually believe if I use Firefox with ubo on windows 7 that suddenly malware would jump on my machine, turn it into a bot and destroy data?

https://www.cvedetails.com/cve/CVE-2011-5046/ is a remote-code-execution attack that works via setting the height of an IFRAME because the graphics device interface doesn't vet the size of the resulting buffers generated to support that IFRAME.

It won't just jump on your machine, but it is a threat you may be continuously vulnerable to for every website you choose to access with an insufficiently-patched Win7 install. And with Win7 now EOL, there are fewer eyes on it looking for vulnerabilities that will report those vulns.
