The ultimate advance in Web browsing without an address bar

■ Design with purpose down to the last pixel

The designer here designed Sleipnir from scratch to provide a Web browser that can make browsing the Web for the people of today even more enjoyable and useful. As a result, we were able to place the number of advanced features such as the easy to view thumbnails that display pages and the evolved search fields that can find open pages in no time into the breathtakingly beautiful and simple toolbar. Each part of the bold looking design has a purpose.

■ Gestures that captivate you the moment you touch

The bothersome task of aiming for a small button with your cursor is unheard in Sleipnir. You can simply use touch gestures with Magic Mouse or the Track Pad to close tabs, go back, and more. Furthermore, because you just need to move your finger tips, bothersome keyboard operations and even just moving the cursor is not necessary. Even if you are holding a mug of coffee or resting your cheek in one hand, you can continue to browse the Web just like usual.

■ Quickly find open tabs even when they reach 100

Compared with the time we first embraced tabs in Web browsers, it is becoming more and more common to simultaneously open a number of pages such as Web applications and social networking. Sleipnir has been carefully designed in every nook and corner so that you can quickly find the page you want from all the rest. Whether you have 100 tabs opened or not a single tab open, you can find your desired page in no time at all.

Best browser ever- needs update after Yosemite - This is the most epic browser ever. I’ve had it for a long time. However, after updating to Yosemite it is no longer my fastest browser. It needs to be updated and reoptimized for the system. Still loving it, but there are a few glitches.

Too small to see - the inability to change font sizes is a HUGE minus. until that’s added, I’ll be using something else.

Version 4.5.8
Review by Time Squire-in-Training

• View menu with Zoom options STILL broken! : ( — use the Black Edition - UPDATE: Sleipnir Browser v4.5.8 — the View menu's page/text ZOOM / RESIZE options are all STILL unavailable (greyed-out) (macOS Sierra 10.12.4). [However, they *are* working in the Black Edition of Sleipnir.] Unfortunately, this makes this Mac App Store edition of Sleipnir Browser pretty much unusable for us, for most of our day-to-day work and browsing.. Otherwise, currently, we would be using Sleipnir almost exclusively. Due to the the lack of zoom in this Mac App Store edition, we must rely on the Black Edition. However, because it's usually necessary for us to often run two seperate, independent web browser applications at the same time, for many different various purposes, we must often turn to a different web browser. Although we CAN and do run the Sleipnir Black Edition and this Mac App Store edition of Sleipnir Browser at the same time, the lack of zoom in this Mac App Store version keeps us from taking full advantage of this functionality. Otherwise, we might usually just run only Sleipnir Browser and Sleipnir Black Edition together, instead of having to turn to other web broswers. Pros: Originated and pioneered many features now found in other browsers. Unique, efficient user interface. Speed. Generally efficient use of RAM memory. Pretty good at handling many open tabs, and preserving them when the browser is quit and relauched. Working with many, many open tabs, and restoring them between sessions, we currently prefer Sleipnir to other browsers. Running the Mac App Store edition of Sleipnir Browser, and Sleipnir Black Edition, at the same time, easily enables using two seperate instances of Sleipnir. Cons: Lack of View > Zoom in this Mac App Store edition of Sleipnir Browser. Very oddly and disconcertingly, Sleipnir sometimes individually prompts to download lots and lots of fonts with Japanese names, while trying to access some American, English-language commercial business web pages — including for example — whereas, other browsers don’t do that for those same sites. (WHY?) Often crashes when toggling JavaScript off. : ( Manual entry of URLs, and Command-click-opening links, produces context-sensitive, inconsistent, and sometimes unpredictable behavior, even between the two editions of the same version of the browser; and, options controlling these behaviors are also inconsistent. Control-clicking on links to access the browser’s contextual menu, doesn’t provide all the usual expected options, such as "open in new tab", etc. Attempting to click-drag-and-drop URLs from the URL field results in inconsistent behavior, including _sometimes_ not even being possible. It isn’t possible to optionally have the full, current URL displayed somewhere all the time, which is actually necessary / helpful for security verification, and often for specific page URL comparison, orientation and navigation. Doesn’t preserve individual tab (back and/or forward) page history between sessions, which some other web browsers do, and which puts Sleipnir at a disadvantage after a crash or necessary closure and relaunch of an unfinished browsing session. Impossible to display more than one web page at a time within the browser application, making direct visual comparison and cross-referencing, and visual monitoring of background pages, impossible within the browser application by itself alone. WAS: Updated! YEA!!! — Sleipnir, one of the most innovative web browsers The Wolf is loose! Yeah! And Sleipnir is ridable again! (It’s no longer constantly crashing into the Finder.) The off-store “black” version has been updated, too! Sweet. By Wotan’s beard, if you’re looking for an ordinary, pedestrian browser, this it not it. This here is Sleipnir. Our patience with and faith in this highly original and innovative web browser developer are justified. Thank you, thank you, thank you! (PS. There’s a bit of oddness with page formatting when turning JavaScript on and off.) (PPS. On a historical note, fyi, other comtemporary browser gesture interfaces, and some traditional holo interface gestures, actually originated with Sleipnir.)

Review by HuzzahBuzz

Scrambled Websites - On Facebook & other mainstream sites, all columns were stacked on top of each other in the center column, making it impossible to read or use anything.
