![]() This was confirmed by the update from 60.0 to 60.2.1. The two builds will use the same profile and have separate shortcuts.įorcing a automated update (using Help -> About Thunderbird or Tools -> Options -> Advanced -> Update -> Check for updates) works for 64 bit release builds. If you do run into a problem (that you want to report as a bug or ask for help using the forums) its recommended that you use custom setup to install a 32 bit build in a different directory, and try to duplicate the problem with the officially supported build. It doesn't mean that you can't get help for it in the forums. What unsupported really means is that QA doesn't test it and you're more likely to run into a regression bug than a supported build. There is no ETA for when they will be officially supported. They won't be officially supported until you see a statement to that effect in either a official blog post or the release notes, or you can download the setup program from the web site. The reason why they're marked as release builds is due to changes in the build system. They seem to work fine but are not tested and are unofficial/unsupported. Ħ4 bit release builds for Thunderbird are available from some Mozilla web sites. There aren't any official 64 bit builds of Thunderbird and SeaMonkey for Windows. Official 64 bit builds of Firefox for Windows are available on the normal download page starting with version 43.0. A 64 bit version might be faster due to it being optimized for CPU's that support x86-64 (it has twice as many general purpose registers and SSE/SSE2 registers as a x86 CPU, and they're all twice the width).Code that uses large data types (64/128 bit WORDs) will be faster because you don't need to play the 'split it into 32 bit WORDs' game.Code that is not careful about memory packing/alignment can run less efficiently as 64 bit.The effective processor cache size will also be reduced. 64 bit pointers are larger than 32 bit pointers, so there's more memory to move around, causing a potential performance hit. Code that uses a lot of pointers will consume more memory.The Firefox source code was taken and compiled in order to. ![]() This updated blog post benchmarks 32 and 64 bit versions of Firefox, including Waterfox (specifically compiled for 64-bit) and concludes that " We should see some performance improvements in the future, but Firefox 64-bit doesn’t appear to give you a faster browsing experience at this time." This Ghacks article compares 32 and 64 bit versions of popular browsers and concludes " Most differences are marginal and not visible to the user. Waterfox Classic provides you with a high-performance browser 64-Bit version of Mozilla Firefox. Typically you only want to use a 64 bit version if the application exceeds the 4GB virtual memory space limit. If you had poor performance before you might not notice any improvement. However, unless the the application is able to take advantage of the wider registers (typically multimedia encoding/decoding, cryptographic, or number crunching applications), you may not see any performance improvement. The Classic edition is the legacy edition of Waterfox that provides support for older OS and also is based on an older version of the Gecko platform which gives the ability to use XPCOM and XUL extensions.You can run a 32 bit version of a Mozilla application using a 64 bit kernel (Windows 7 圆4 etc.) though a 64 bit version "supposedly" increases performance. Waterfox is available in two editions Standard and Classic. Moreover, there is no plugin whitelist, you can run whichever extensions you like and absolutely no data or telemetry is sent back to Mozilla or the Waterfox project. It’s partnered with Ecosia, a search engine that plants trees with its generated revenues (Ecosia is the default search engine of the browser). Today, it has over 6,000,000 downloads spanning 180 countries.Īlex Kontos created the browser to focus on giving users choice while also helping make the world a better place. It was started back in March 2011 by Alex Kontos, a 16 - year old student. It was also one of the first widely distributed 64-Bit browsers on the web and quickly gained a loyal following. Waterfox was the first community Firefox built to release a 64-Bit version of Firefox 4 when it first came out. It contains modifications designed to take advantage of the 64-bit system architecture and provide speed improvements over Mozilla’s flagship browser. Waterfox browser offers many optimizations compared to the original Firefox source code and puts a focus on performance and speed. Waterfox is compatible with Windows, Mac OS, and Linux operating systems. Waterfox is an open-source, high-performance Firefox-based browser for Windows, Mac OS X and Linux, that is designed specifically for 64-bit systems and for privacy and user choice in mind.
