It's really not all that bad.
hg clone http://icedtea.classpath.org/hg/icedtea-web
The user-links step installs the plugin for your user account, and your
account only. To uninstall it afterward, cd back to the
icedtea-web/build directory (if you aren't already there) and run "make
restore-user-links". Then you can delete the icedtea-web directory if
you so desire. Note that you will have to restart your browser after
running make user-links in order for it to be recognized.
If you can somehow get profiling information on which method(s) are
eating up CPU time then that would be great, however.
You're also using a very old version of IcedTea-Web there (1.2.3) -
looks like Peppermint is (unfortunately) pulling from Ubuntu's 12.04 LTS
repos for that, because I know 13.10 actually has 1.4 in its repos. It's
quite possible that this problem will be fixed just by upgrading to
something more recent. If you'd rather go this route rather than
compiling from source, go to  and select the icedtea-netx and
icedtea-netx-common packages from a newer release such as Saucy, which
has 1.4. Then download and install them on your system just like any
other .deb. The download links for Precise will bring you back to the
currently installed versions you have now, if you need those to
downgrade later on.
Note that I'm not a Peppermint or Ubuntu user at all, so I can't really
provide too much support with this in particular. It *should* be
completely safe, but I make no guarantees :)
Since it's affecting 1.2, I wonder if it's this  bug, or something
