Hi
I'm a web developeder. Main apps for browsing and email the past 20 years have been FF and TB.
I'm using this gadget in FF that shows viewport width (the little ruler icon top right in developer window) for responsiveness. What bugs the crap out of me is that it's now way to make the measurement(s) stay in the browser window. When working for an hour, I need to re-launch the measuring (i.e. click the ruler icon) at least 20-30 times.
Can you please fix an option to make it stick until I select to hide it?
(Hope you understand what I mean. Not english spoken)
Cheers
Dan
