Recently I’ve had a problem with my text boxes (“TEXTAREA”s, in HTML parlance) being truncated at 2,048 characters.

If I go to a form with a textarea that is auto filled with more than 2,048 characters, the form contents is silently chopped off at 2,048 characters. This is obviously quite annoying. Today I was needing to edit a bug report for work and decided to track down the problem. I started disabling AddOns one at a time, and eventually I found the problem.

Here’s the scoop: GreaseMonkey plus Firefox 2 plus long forms equals FAIL.

The GreaseMonkey addon for Firefox lets you write text scripts that get executed on webpages that you look at. I was using it to create automagic links based on text that it was seeing in webpages. But, there’s a bug with the way that Firefox 2 processes webpages (I won’t go into details here) that causes textareas to get chopped off after 2,048 characters. The easiest solution that I’ve found is to upgrade to Firefox 3. But, since I can’t do that, I’ve had to just get rid of GreaseMonkey.
