Firefox Find feature not working in textarea

One of the thing I dislike most about Firefox is the inability to use the find function within textareas. This is very annoying when it comes to editing php/js codes or templates which have very lengthy and complicated structures.

The Find (Ctrl+F) is especially useful to skim through a large number of words to get to the specific terms easily. I use it all the time either surfing, reading, or coding.

So, a little search on google I found this:

https://bugzilla.mozilla.org/show_bug.cgi?id=252371 (official bug report)

So (again) why isn't it implemented? Are they disabled on purposed for some sort of security reasons? Or is it just like what the other guy said that they just haven't fixed it?

It's really annoying when I can't get things done due to limitations. And it have a very serious performance hit. The only way I can get this done is to "View Source" and find through the source code. It doesn't work all the time especially when it comes to situations with escape HTML tags such as &lt;(<) &gt;(>) &quot;(")

Does anybody know if there's a fix / greasemonkey-hack / firefox-extension
that I can download?
