Resolve GMail Undefined Issue – Firefox
I’m fickle about browsers. Safari has some very nice features such as the ability to resize text boxes in forms. It also syncs bookmarks to my .Mac Mobile Me account to my other Macs and my iPhone. On the other hand there is much to love about Firefox 3. The biggest thing I like is the ability to have multiple home pages that open when I launch the browser. I know in Safari all I need to do is Command-click the bookmarks folder that contains all of my preferred pages. Still, if I can, I prefer to skip that step. I also like Firefox’s ability to use GreaseMonkey scripts to tweak certain webpages.
GMail Undefined Items
Because of the different features I will switch between browsers, using each one until I get frustrated with the its limitations.
Recently, I’ve been using Firefox and I noticed that my GMail messages would show “undefinedX” where the To: and the From: address as well as a number of other items are supposed to be displayed. I quickly checked in Safari to see if it was a browser specific issue. Sure enough, when I view the messages in Safari, all the information is where it is supposed to be.

GMail Conversation Preview Script
One of the GreaseMonkey scripts that I use is the GMail Conversation Preview. I have to say that the one thing I really miss in GMail is the ability to see the message in a message pane without having to essentially open up the message. GMail Conversation Preview was a bit of a work-around for this.
A bit of searching on the web revealed this conversation over at Digg where user Kenley pointed out that the issue is caused by the GMail Conversation Preview GreaseMonkey script. By disabling GMail Conversation Preview all the information items return to normal.
To disable a GreaseMonkey Script in Firefox for Mac simply go to the menu bar and click on Tools -> GreaseMonkey -> Manage User Scripts… When the window opens, highlight the GMail Conversation Preview script and uncheck the “Enabled” button that is in the lower left corner of the Manage User Scripts window. Close the window. To see the results, use the refresh button in Firefox to refresh GMail and see the changes.
