I used to be a Firefox loyalist, but after reading your browser roundup (“¡Lucha Libre de Web!” Dec/09), I switched to Safari. I’m loving the speed, but I miss being able to reopen the last closed tab. Safari will reopen my last closed window, but I typically use just one window a day, opening and closing dozens of tabs.

Check out Glims for Safari (free, machangout.com), a handy add-on that lets you undo closing a tab. Yep, you just press Command-Z and your last closed tab reopens. Press Command-Z again, and the tab you closed before that reopens. Glims has other tricks up its sleeve too, like letting Safari run in full-screen mode, letting you change the default search engine, adding thumbnails to your Google search results, and more. After you install Glims, you can control its many behaviors via the new Glims tab added to Safari > Preferences.

Glims adds many tab-wrangling features to Safari, even letting you specify the location of newly opened tabs in Safari's tab bar.

One caveat: Glims’ developers don’t recommend you use Glims alongside similar Safari plug-in Saft ($15, haoli.dnsalias.com/Saft/), or you could get “unexpected results.” If the letter-writer had Saft, they probably wouldn’t have written us this letter, but the rest of you should proceed with caution if you’re already running Saft.
