Software has usually between 15 and 50 defects per 1000 lines of code.

Some say it is larger - from the above link:

This observation is very old, and comes from a very venerable source, namely Fred Brooks in his book "The Mythical Man Month". He was a top manager at IBM, and managed many programming projects including the milions-of-lines operating system OS/360. In fact he reported that the number of bugs in a program is not proportional to the length of code, but quadratic!

Firefox 20 has about 4 millions of lines of code.

Using the rough and perhaps optimistic estimate from above, it could have between 60,000 and 200,000 bugs, and perhaps much more.

So, while this is a finite number, in practical terms, the number of bugs is unlimited.

And bugfixes can introduce new bugs, especially in large + compkex codebases.
