best

Sin duda, el mejor. He usado varios, pero algunos tenían fallos en Linux o con algunas páginas. Éste además tiene una página de demostración interactiva justo después de instalarlo.

Totalmente recomendable.

挺好用的，但是不能在不同firefox之间同步设置，必须重新设置一遍。Chrome上没有这个插件啊，可惜

This gesture extension works the best for me. Others sometimes confuse down-up with just down, which for me is the annoying difference between close and reload tab.

Yes this addon does what it claims to do, but remember to have all actions screenshoted. I took a backup last month and now reinstalled Firefox, then tried to restore it. I know the backup was valid because I tried restoring with that backup file right after creating it (and it was successful). Guess what I got today? It says the backup is not valid. The backup format is not consistent across versions, and is without backward compatibility.

Wow i am enjoying and recommend this add-on for everyone. Because it is a timesaver like you cannot imagine!
