Swiftfox is a web browser based on Mozilla Firefox. It is available for Linux platforms and distributed by Jason Halme. Swiftfox is a set of builds of Firefox optimized for different Intel and AMD microprocessors. Swiftfox is freely downloadable with open source code and proprietary binaries. Firefox extensions and plugins are compatible with Swiftfox, with notable exceptions. The name Swiftfox comes from the animal Swift Fox. Swiftfox differs from Firefox by a limited number of changes, and builds for different processors. As these differences are technical, for general information on the browser see Firefox. == Optimization == The Swiftfox build is optimized using the following methods: Binary code optimization *Compiled with the highest level of compiler optimization, rather than optimization for binary size. * * Swiftfox is compiled -O3,〔Using url of ''about:buildconfig'' to check the details of the 2.0 builds〕 (the highest level) * * *The resulting Swiftfox binary is larger than Firefox. (-O3 is not necessarily faster than -O2, or -Os. -O3 introduces two more options on top of -O2: -finline-functions and -frename-registers. The latter is good for CPUs with many registers but may actually be slower on other CPUs.) * *Firefox is compiled -Os.〔 (-Os is the same as -O2 but removes optimizations which would increase the binary size.〔) *Binaries incorporate additional instruction sets. * * Intel and AMD: MMX, SSE, SSE2, (not generally SSE3). * * AMD only: 3DNow! *Optimization specific to the build microprocessor architecture.〔 * * Intel: Pentium 4, Pentium 3, Pentium M, Pentium III, Pentium II, Pentium 4 (Prescott). * * AMD64: Athlon64 (32bit binary). * * AMD: Athlon XP, Athlon, K6-2. *Compiled with newer version of GCC (Firefox 2.0 uses 3.3.2, Swiftfox 2.0 uses 4.0.4).〔 Increased Security *Better protection from Buffer overflow attacks〔(【引用サイトリンク】 publisher =redhat.com )〕 (Swiftfox 2.0 uses -D_FORTIFY_SOURCE=2; Firefox 2.0 uses gcc 3.x, which does not support this).〔 Simplify *Pango is not included in the build . This means that Unicode fonts remain supported (see Unicode and HTML), but without certain extra features provided by Pango. This simplification reduces the binary size, and reduces rendering. Changed default preference values *IPv6 DNS lookups are disabled.〔 preventing slowdowns experienced *HTTP pipelining is enabled by default.〔〔 Fasterfox provides a GUI to adjust these settings. *For full details, see (). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Swiftfox」の詳細全文を読む スポンサード リンク
