Before WP 3.0 if you pressed tab in WordPress's file editor it didn't insert a tab indentation so I used a plug-in for Firefox.
After updating to WP 3.0 I uninstalled the plug-in noticing that WordPress recognized tab as an indent now; however, whenever I press tab it freezes the browser for 7-10 seconds and then finally enters the indent.
I have tried uninstalling all Firefox plug-ins and all WordPress plug-ins but nothing seems to remedy it. Has anyone else had this problem?
Is there a way to disable WordPress's tab indentation feature?
