I have created a web page an in Internet Explorer, Sfari, Chrome and Opera all the text fits perfectly and renders well. But in Firefox the text (font is suppose to be Arial 12pt) is too big and the last line gets cut off as it exceeds the allocated space and the way the text is renders looks harsh.
Text will only get cut off if you specify the height of the container or position elements absolutely and that is usually not a good idea.
It is always best to let the browser manage the height to avoid such issues in case the visitor wants to use a different font family or font size.
It also looks that the text in Firefox is bolder or another font is used.
You can use this extension to see which fonts are used for text that is selected (right-click context menu: Show fonts in selection).
I tried resetting the View but it did nothing it's already at the right level.
I have noticed that if I start FF in Safe mode it works just right, but not in the normal mode, I have disabled all Add-on, Plugin-in, reset FF and even uninstalled and re-installed it but to no avail.
How can I debug from Safe mode to figure out the cause of the issue?
