To continue with browsers and again non-competitively, I’d like to mention Lunascape. Lots of browsers do interesting things, like Opera’s managing email and ‘Turbo’. Other browsers have their special features a well. Maxthon can switch between 2 rendering engines.
Lunascape can jump between three rendering engines – Trident (IE), Gecko (Ff) and WebKit (Chrome and Safari). It does that effortlessly. Depending on compatibility, the rendering of a given site might suffer. If that happens, the switch over is simple, or you can elect to have a three paneled side by side display of the same site with the three engines.
One drawback is that it it hasn’t been bechmarked since 2011. At that time it seemed to be in the middle of the pack (15 browsers tested) with Google V8 Javascript Version 6 Benchmark, and Microsoft Fish Tank Benchmark 1,000 Fish but, was fastest with WebKit SunSpider 0.9.1 Javascript Benchmark (http://www.legitreviews.com/article/1610/2/).
My own impression is that there is very little difference among the 3 engines in rendering the WC Homepage, and that Lunascape appears only slightly slower than Comodo-Chrome.
It has an enhanced floating taskbar which can be very useful, because it acts almost like a widget so you can use multiple Firefox sidebar add-ons at a time or move them from one monitor to another.
Speaking of add-ons, Lunascape has a special add-on organizer which packs them up and categorizes them automatically. Also, it is compatible across a large range of Ff add-ons (3.x). The same is true for the Trident engine and its extensions, and Gecko as well… and Lunascape with its plug-ins.
Lunascape also will import favorites, set keyboard shortcuts (from the other engine) as well as profiles, cookies, passwords, etc. and is very customizable in its settings for each engine:
You also get a ‘minimal’ Orion interface, which is customizable.
Even better, beyond unifying four major browsers in a single platform, Lunascape has extended API’s for easy extension development (someone’s considering the devs!).
There’s a ‘Lite’ version and a portable version as well as a version for iPhone and the iPad. It comes in 12 languages, and the homepage is here: http://www.lunascape.tv/Home.aspx
