quick tip for firefox error code:
- In the Firefox address bar, type about:config and press Enter.
- Scroll down and find the entry that says dom.max_script_run_time
- Double-click on that entry and change the value (the default is 5) to something higher. Most sites recommend 20, but I found that I still received the pop-up warning too often. So I changed it to 1000!
- Click OK.
- Restart Firefox
