Highlight IP addresses with a double click in Firefox

·145 words·1 min·

My daily work involves working with a large number of servers and one of my frustrations with Firefox is that it’s not possible to select an entire IP address with a double click with the default settings. Although it works right out of the box with Safari, you have to make a configuration adjustment in Firefox to get the same behavior.

To change the setting in Firefox, open up a new Firefox tab and go to about:config in the browser. Paste word_select.stop in the search bar that appears below your tab bar and double click the layout.word_select.stop_at_punctuation line. It should become bold and the value on the end will flip from true to false.

Go back to another tab and open a web page which displays an IP address. Double click on any portion of the IP address and Firefox should highlight the entire address.
