Some websites automatically place the cursor in important text boxes for you. Others are not so courteous. A quick Firefox tweak makes it easy to jump right to the text boxes.
At the technology blog gHacks, they’ve shared a simple about:config tweak to make text box navigation easier. Unfortunately there is no hack for making the first text box on a page automatically in focus. You can however make jumping to the first text box really keyboard friendly.
Type about:config in the address bar within Firefox. Use the filter function to search for accessibility.tabfocus.
