Firefox is no longer default browser after cleaning

Hi guys !

CCleaner last release (2.00.491b2) always try to remove 2 registry keys : file.extension xht and xhtml.

If I allow registry cleaning, firefox is no longer my default browser (till I check again on prompt).

Is it a normal behaviour ?

Many thanks for your replies.

That shouldn't cause it - that's just deleting old extensions. However, it is in beta, and it might be causing the problem. Just revert back to the old version and you should be fine.
