Stainless 0.5 browser
Mesa Dynamics has released what it calls a "significant" update to its proprietary web browser, Stainless. The app is now being developed as a full product rather than a technology demo, and predominantly features separate processes for each tab, as in Google's Chrome software. The scheme can dramatically increase speed and memory efficiency while browsing, as well as stability.
Version 0.5 of Stainless introduces the concept of "parallel sessions," which let users log into a single site with multiple simultaneous accounts. In accessing Gmail for example, three different inboxes can be loaded across three separate tabs. The content is further integrated into bookmarks, allowing several site logins to be loaded in short order.
The browser has also been given a vertical bookmark shelf, said to be efficient in terms of screen space, and single-window as well as page source views. Like Safari 4, Stainless is now HTML5-compliant, permitting offline operation. The browser is a free download for Mac OS X Leopard.
