Google Chrome's Pin Tab feature shrinks any tab down to only a web site's favicon to save precious tab bar real estate—no extension required.

In August we detailed how to set up space-saving, icon-only tabs in Firefox so you've always got quick access to your most-used webapps (like Gmail and Google Reader) without wasting a lot of tab bar real estate. The FaviconizeTab Firefox extension is the secret sauce to that setup, allowing you to shrink any tab down to just the site's favicon (the small icon image already in the tab); in the most recent dev channel releases of Chrome, you get the same functionality without needing to install anything. Here's how it works:

Google Chrome: Want to keep track of what you've got open in Google Chrome? The experimental SessionSaver extension can save and load multi-tab, multi-window sessions and restore them with a few clicks.

Installing SessionSaver, or any Chrome extension, requires running Chrome's developer version, available using the Channel Changer tool, and adding --enable-extensions to the end of your Chrome launching shortcut, right after the chrome.exe bit. Once that's done, head to the link below and click on the first link to download and install the extension.

Using it is fairly simple. There's a save-icon-like button installed in Chrome's bottom status bar. Click on it to get load, save, and settings options, where you can save either just one window's tabs, every window's tabs, or load a previous session into your current tabs. Helpful for starting up multi-tab projects or saving your web progress when you're venturing into crash-prone territory.
