Actually we are supporting only versions starting from 8, so this version check
is not necessary here.
BTW, how does it affect the performance?

I would remove it.

You and Oleksandr and I had a discussion about this several weeks ago. The
decision made at the time was to leave all the version checks in, because we
were going to continue to allow people to install the plugin on old versions,
even if that meant shooting themselves in the foot.

Regardless, we need to ensure that the plugin does not install on old version of
IE before we simply remove checks that operate at run time.
