Why does the Sony store website for the US (http://store.sony.com) not work properly on Firefox?
A lot of page elements do not work properly on that website when you access it via Firefox. For example, bars that are supposed to be interactive and can be slid from right to left for viewing an attached panel of options do not slide. Buttons that are supposed to change the colour of the laptop preview images do not work. And a lot of other buttons supposed to link you to another page or function as selection buttons do not work as such and simply redirect you to the top of that same page.
All of these problems are nonexistent when you access the website with IE.
Use a compressed image type like PNG or JPG to save the screenshot.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
