I am a developer of a JavaScript-based search engine Everyfind. This software is available since 1999. I have installed the latest beta and found it cannot execute a large script, generated by Everyfind (see URL for exaple). Old versions of Firefox are work correctly with large scripts. Please fix it.

Details: the script has a 16 megabytes of .js file with a database arrays. A 9-megabytes version is works correctly.

Reproducible: Always

Steps to Reproduce:
1. Download the zip file
2. Unzip it
3. Start search.html

Actual Results:  
Error: script too large
Source File: file:///D:/Temp/demo%2012000%20links/searchdb.js
Line: 81079, Column: 1
Source Code:
//DatabaseEnd 

Expected Results:  
It should execute the script correctly. Tested on Firefox 2.x

Does it help if you disable jit ?
open about:config, confirm the warning, enter jit in the top filter box and set javascript.options.jit.content to false and restart FF (don't forget to enable it again after testing).

Matthias, disabling jit using your instruction does not fix the problem.

Also I have tried to disable addons - no changes.

I have tried to install the latest stable firefox version (3.0.8 english) - this version works correctly and fast.
