JetPack Gallery Opens with No-Restart-Needed Firefox Extensions

JetPack, the Firefox add-on system that uses only HTML, JavaScript, and CSS, has opened up its own gallery of apps. The pickings aren't exactly plush, but there's some neat stuff that doesn't require a restart to try out.

JetPack, as we've previously summed it up, falls somewhere between the site-specific scripts of GreaseMonkey and full-blown Firefox add-ons. They can add to Firefox's chrome and bring up dialogs if you've got JetPack installed, but they don't require a total browser restart or compatibility check to install—just a site refresh.

At the gallery, you can install JetPack and try out some neat stuff, like the GTranslatifier, which can translate entire pages or selected text with a status bar click. There's also a JetWave notifier for Google Wave messages, and a sidebar tweak, Thumbtabs, that offers Opera-like visual browser tab thumbnails in a pop-out sidebar.
