I'm using the LATEST version of FIREFOX. Deleted old and installed newest version.
When I create a new email, every two lines, the FONT gets bigger.
This does NOT happen in CHROME.
What the --------?
Solved! Go to Solution.
That is a bug in current Firefox versions (fixed in Firefox 19).
(please do not comment in bug reports: https://bugzilla.mozilla.org/page.cgi?id=etiquette
FF19 did not resolve the issue with yahoo mail. Unfortunately... Here's what's happening on PCs I run (several with the same behavior): if page text is zoomed at anything than 100%, regardless whether you use FF's built-in zoom or extensions (e.g. NoSquint, or ZoomPage), the font size increases with every new line when typing a reply in yahoo mail. Zoom text back to 100% and font issue goes away, but becomes a big usability issue on hi-res monitors due to 100% text being way too small. Zooming the entire page but keeping text at 100% seems to work too if you can tolerate fuzzy images.
IE (IE9 and IE10) handle yahoo mail font size correctly even when zoomed, but IE zooms entire page, not just text, therefore it is probably not a fair comparison. Have not tried Chrome.
So it seems to be a FF text zooming bug and it is still there. Anyone can confirm my observations?
