RealPrevNextButtons for new Thunderbird versions 0.3 Requires Restart
by FireballMonkey
Real previous & next buttons for message navigation, updated to support Thunderbird versions through 10.x (and probably future versions). Tested with Thunderbird 9.0-10.0.2 on Ubuntu 11.10, Windows 7, Windows XP, and Mac OSX.
About this Add-on
This add-on is a modified version the RealPrevNextButtons add-on by Shadow912. The hard-coded CSS was replaced with JavaScript to actively clone the style of the regular previous and next buttons on startup, allowing the icons to be correct regardless of the platform and Thunderbird version.
