What website is this happening on? Can you give an example of a page that does this? Thanks!

Firefox .......I have aapl bookmarked ...and this happens......first the correct page appears then quickly the page becomes squeezed tall and thin

Can you please give the specific address of the page this occurs on? Thanks!

You may have zoomed web page(s) by accident. Reset the page zoom on pages that cause problems.

• View > Zoom > Reset (Ctrl/Command+0 (zero))

If you have made changes to Advanced font settings like increasing the minimum/default font size then try the default minimum setting "none" and the default font size 16 in case the current setting is causing problems.

• Firefox > Preferences > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow pages to choose their own fonts.

• Firefox > Preferences > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

It is better not to increase the minimum font size, but to use an extension to set the default page zoom to prevent issues with text not being displayed properly.

Is this on Yahoo Finance? For example: http://finance.yahoo.com/echarts?s=AAPL+Interactive#{%22range%22:%223mo%22}. I have attached a screen shot of what I see for that link.

It seems they have redesigned this chart recently and scrolling the mouse wheel changes the selected period -- for me, the amount of data in the chart changes, but the width of the chart stays the same.
