In canvas, while setting textBaseline property to \'top\', its rendering differently in chrome and firefox. In chrome, there is a gap between line and the text where as there is
I agree with the OP that this is an issue and it's peculiar to Firefox. Increasingly though, it seems that Firefox has adjusted the vertical offset overtime. It was once once about 4 pixels, then 3. Now, it is almost imperceptible. So, I agree with @Kaiido above. Use/set *object*.textBaseline="alphabetic";
I believe that this is consistent across browsers.
