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;

[download]

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;
