When I recently updated my browser, Firefox, to the latest release and noticed that some of my extensions also needed to be updated. I do not use many extensions, but I absolutely love and rely on the Web Developer Extension. I had not gone through all the drop down menus in awhile within the Web Developer Toolbar, so today I thought I would just look around a bit more…and I am glad I did because I found another awesome tool for web development: the ruler. (This feature was added in a previous version, it is just new to me.) If you like a certain web site or want to take measurements of a particular page element, you can measure it quickly and easily by clicking on the “Miscellanous” menu and then by choosing “Display Ruler”. You can then either enter in dimensions, or expand the ruler yourself to measure something. This is wonderful!
