A patch can be applied by issuing the following command:

patch -p0 < patch-file

This has to be done in the correct directory. Simply look at the patch file, in the first few lines you should see something like this:

  --- pixman-remap.h   22 Aug 2005 04:02:33 -0000      1.5 
  +++ pixman-remap.h   21 Nov 2005 19:46:40 -0000      1.7

This tells you that you will need to find the file pixman-remap.h and change to the directory containing this file before you apply the patch.

tar -C dist -jhcf firefox.tar.gz bin/

If your Y-axis label gets cutoff in Excel then add some …….. (fullstops) at the end. Change the colour of the fullstops to match the background colour so they won’t be seen.
