Windows/Mac/Linux: Thunderbird, our favourite Windows and Linux email client, updated today with a few new features to make browsing your email more convenient, including keyboard shortcuts and search in the context menu.
Like its brother Firefox, which also updated today, Thunderbird has fixed add-on compatibility checking so your add-ons will stay enabled by default. This solves problems with Thunderbird's new rapid release schedule, in which add-ons were often compatible but not updated to say so.
It has also added the ability to right-click on a phrase in your email and search that term on the web. By default, it searches inside Thunderbird, but you can tweak that with an about:config hack. Lastly, it has a few new keyboard shortcuts, like Ctrl+Shift+A to add an attachment. Hit the link to read more.
