How do I access the MapleStory website without using Internet Explorer?

The MapleStory Global website checks to see if the browser you are using is Internet Explorer or not. If it isn't, it will block you from accessing the website. This check is done using Javascript, so to access the website you need to disable Javascript. You will need to enable Javascript again once you are done to continue browsing other websites as some may not work properly without Javascript.

Disabling Javascript varies between browsers. If using Firefox, click on the "Tools" menu, then select "Options". Click the "Content" button and there should be a number of checkboxes to enable/disable certain features. Clear the checkbox beside Javascript, and select "OK". Now, when you visit the website it should allow you in.

Another option is to download the IE Tab extension from the Mozilla website. Once downloaded, select the Sites Filter tab from the top, then add http://*.nexon.net/* (the * acts as a wildcard) to the URL list. Make sure that the box at the top of the window is checked.
