No problem, just a general developer's question: what is the maximum length for a query string URL in Firefox?

Chosen solution

Quoting Boutell.com and StackOverflow:

“After 65,536 characters, the location bar no longer displays the URL in Windows Firefox 1.5.x. However, longer URLs will work. I stopped testing after 100,000 characters.”
