 As SVG derives from XML it is not known to be particularly economical in terms of file size. Compressed SVG, with file extension `\verb+svgz+', shortens download times and is supported by most Web browsers. It can be generated by adding option `\verb+-z+'. Also, option `\verb+--precision=1+' may be used to reduce the SVG file size. It limits the precision of floating point numbers, such as coordinates, to one decimal figure. Sometimes, animations may behave stangely after applying this option. Then, of course, it should be omitted.

 \begin{itemize}
   \item The maximum frame rate that can actually be achieved largely depends on the complexity of the graphics and on the available hardware. In Acrobat Reader, you might want to experiment with the 2D graphical hardware acceleration feature. Go to menu `Edit' $\rightarrow$ `Preferences' $\rightarrow$ `Page Display' $\rightarrow$ `Rendering' to see whether hardware acceleration is available. A 2D GPU acceleration check box will be visible if a supported video card has been detected. Also, enabling or disabling the page cache (`Edit' $\rightarrow$ `Preferences' $\rightarrow$ `Page Display' $\rightarrow$ `Rendering' $\rightarrow$ `Use page cache') may affect the rendering performance.
 
-  \item Animated SVG is best viewed in Web browsers that are based on the Blink rendering engine. The most prominent representatives are Chrome, its open-source base Chromium and Opera. Unfortunately, Firefox is very slow.
+  \item Animated SVG is best viewed in Web browsers that are based on the Blink rendering engine. The most prominent representatives are Chrome, its open-source base Chromium and Opera. Unfortunately, in Firefox some animations run slowly, especially if the graphics make use of clipping operations.
 
   \item The \verb+dvips+ option `\verb+-Ppdf+' should be avoided entirely or followed by something like `\verb+-D 1200+' on the command line in order to set a sensible DVI resolution. This does \emph{not} degrade the output quality! The configuration file `config.pdf' loaded by option `\verb+-Ppdf+' specifies an excessively high DVI resolution that will be passed on to the final PDF. Eventually, Acrobat Reader gets confused and will not display the frames within the animation widget.
