Tracking development snapshots of Mozilla Firefox can be fun, especially when the thing almost always (sic!) behaves like a friggin' -final, which is a good thing. However, this means of course that plugins have to keep up with the pace set by this development, which is hardly possible for all available plugins. My favourite plugin, Flashblock, says: Works with: Firefox 1.4.1 – 3.0a7 But 3.0a8 is already out! Let's try something then:

# wget --no-check-certificate https://addons.mozilla.org/en-US/firefox/downloads/file/17855/flashblock__45_1.5.4.1__45_fx__43_fl.xpi # mkdir fb && cd fb && unzip ../flashblock* # sed -ie 's/3\.0a7/3.0a9/' install.rdf # zip -9r ../flashblock-1.5.4.1-fx+fl_3.0a9.xpi *

Now install this new .xpi - if we're lucky, that's all it took to change. If not, RTFS :-\
