Yitzchak was going through some old web code, and found some still in-use JavaScript to handle compatibility issues with older Firefox versions.
if ($.browser.mozilla &&
$.browser.version.slice(0, 1) == '1')
{
…
}
What a marvel. Using JQuery, they check which browser is reported- I suspect JQuery is grabbing this from the user-agent string- and then its version. And if the version has a 1 in its first digit, we apply a “fix” for “compatibility”.
I guess it’s a good thing there will never be more than 9 versions of Firefox. I mean, what version are they on now? Surely the version number doesn’t start with a “1”, nor has it started with a “1” for some time, right?
