GoogleTabs was an extension for Mozilla-based Web browsers that opened Google search results in tabs via an option in the context menu.
The last version of GoogleTabs was version 2.3. This version had support for all of the major Google searches: Web, News, Image, Groups, Local, Scholar, and Froogle. It also supported opening all of the News main page stories in tabs and all of the topics of a group in tabs.
GoogleTabs is no longer available for installation, but you can download the source of the last version for reference purposes. My extension Links Like This is an attempt at generalizing GoogleTabs for all webpages.
Note: even if you package this code into an extension, it will not work with the latest Google search pages, as they’ve modified their HTML since the 2.3 release.
