in thread Need to turn off prints from module
For my tests, I used the problem string you posted then added three more from browsers I had handy on my PC. I notice that the Firefox one you've now posted has "+" characters in every position that mine has spaces (ignoring a few minor variations in version numbers). I took mine directly from the browsers; it occurred to me that may yours are perhaps URL-encoded (while you can represent a space as hex %20, it can also just be converted to a plus-sign).
So, I added your latest problem string to my existing test list and changed:
$useragent =~ s{ ( [+] ) [[] [^]]+ []] ( [+] ) }{$1$2}msx;
to just:
$useragent =~ y{+}{ };
And it all worked! :-)

So, give that a go - it might be the solution.
If not, you can redirect STDERR (see open - example code is about halfway down the page) but you'll lose every error message by doing that and I really wouldn't recommend it.
In the _numify() routine (referenced in my last post) pluses are actually removed (see final alternation item):
$v =~ s{ pre | rel | alpha | beta | \-stable | gold | [ab]\d+ | a\-XXXX | \+ }{}xmsig;
So, if my solution works, you might want to post a bug report with the fix being:
$v =~ y{+}{ }; $v =~ s{ pre | rel | alpha | beta | \-stable | gold | [ab]\d+ | a\-XXXX }{}xmsig;
