Rated 1 out of 5 stars
Unusable on FF 26.
CPU jumps to 100% every several seconds.
Console shows this:
usingOldMemoryReporter returnValue = false
refreshMemoryNewCallback aProcess=, aUnsafePath=resident, aKind=2, aUnits=0, aAmount=540528640, aDescription=Memory mapped by the process that is present in physical memory, also known as the resident set size (RSS). This is the best single figure to use when considering the memory resources used by the process, but it depends both on other processes being run and details of the OS kernel and so is best used for comparing the memory usage of a single process at different points in time.
Once I disabled this addon, the problem stopped.
We have submitted for Mozilla review version 1.14 which fixes the high CPU usage issue. You can also download version 1.14 now from http://goo.gl/Ur4u7k. Please let us know if you continue having issues.
