Firefox crashes when I go to Articles & Categories section

There was an issue introduced in Firefox v10. When you're using Firefox v10 or higher in the admin area of KMP, it crashes on Articles & Categories page (and sometimes on some other pages).

There is a simple workaround that helps you to keep using Firefox v10 or v11 with KMP. You just need to adjust one of the Firefox options (in fact, disable one of the things that improves performance a bit, which is not working properly at the moment):

The Workaround

1. Type "about:config" in Firefox address bar and press Enter.

2. It will show a confirmation. Don't worry, click "I'll be careful...". We know what we're doing.

3. You'll see a large list of under-the-hood options. Copy this to the filter field and wait a second: javascript.options.typeinference

It will show you exactly one option:

4. Double-click on it to switch it to "false":

5. Now close all Firefox windows and start Firefox again. It should not crash when you work with KMP now.

Later, when the fix will be included to a Firefox release, you should switch this option back to "true". You will gain about 5-10% performance improvement.

Some Other Workarounds

There are other workarounds that are not so good. You can try them if for some reason the workaround mentioned above doesn't work for you.

• Use a different browser, for example Google Chrome or Internet Explorer
• Roll-back to an older stable version of Firefox. Firefox 9.0.1 works like a charm. Download Firefox 9.0.1 US for Windows. Other languages and platforms. 
• Install and enable Firebug addon for KMP site (see the details below)
