Using Yahoo Mail
Firefox 14.0.1Yahoo Edition Yahoo-1.7
When typing a response etc in Yahoo Mail the font size automatically increases after hitting enter and or backspace. font size continues to get bigger each time enter is used. This seems to have started after updating Firefox. On Yahoo mail boards some are saying this does not happen on IE.
Firefox remembers the page zoom by domain, so it looks that you've zoomed some pages.
You can reset the page zoom on pages that cause problems.

Thank you cor-el,
Hitting ctrl 0 does stop the font from increasing.
I don't remember this auto increase happening before. Seems annoying enough that perhaps Firefox will resolve the automatic thing.
You may have hit the Ctrl and + shortcut key or had the Ctrl key pressed when scrolling the page with the mouse wheel.
This is not a page zooming problem. The emails generated at yahoo contain the larger fonts embedded in them. The recipients of the emails receive the emails with larger fonts. The font size increases with every new paragraph in the email. Deleting all yahoo cookies on the client of person composing the email has no impact. If the composer switches to IE, the problem is eliminated for both the composer and the recipient.
TL;DR -- Not page zoom, progressive font size increases are in the sent email, recipient also sees it, doesn't happen when composing in IE.
So is it a Firefox problem or a Yahoo problem? Hitting Ctrl 0 does make it go away but I wonder why it just started doing this. Dennis
If Ctrl + 0 works then you have zoomed the page and it is a zooming issue.
If it is carried over with the email then you have added formatting information to set a specific font size.
If such tags aren't closed properly then you get an increasing font size with every paragraph.
Thank you Cor-el. I can live with it or switch back to IE. And yes some emails have small fonts so I zoom those. But I never had this problem before and it appears others have experienced this. My suspicion is either Firefox or Yahoo has changed something to cause this.
EDIT - My last solution didn't actually work, sorry. If you manually reset the font size before entering a message the issue sometimes stops.
