I just recently downloaded Firefox on my Nexus 5, when I type in the URL it sometimes autocompletes the URL, the problem is it no longer stays highlighted.
Example: I type in the letter "C" to go to CNN.com, after I type the letter "C" it autofills/completes the web address custommagnums.com, normally this URL would stay highlighted so you could just keep typing, but it completes the whole URL and unhighlights it, leaving me to select it and delete it and start over.
