Daily dilbert on firefox 4

The extension i missed the most after upgrading to firefox 4 is daily dilbert. This extension has not been updated for quite sometime, so i decided to give it a try by forcing it to install of 4.0. One way is to disable compatibility checking in firefox, but i decided to modify the extension to claim as supporting firefox 4.0. Below are the steps for linux

• Download daily dilbert extension for 3.6 (using older firefox or any other browser like chrome/opera)
• From terminal execute the following steps
• mkdir daily.dilbert
• cp daily_dilbert-2.6-fx.xpi daily.dilbert
• cd daily.dilbert
• unzip daily_dilbert-2.6-fx.xpi
• Use vim or any other editor to edit install.rdf and change 3.6.* to 4.0.*
• zip daily_dilbert-2.6-fx.xpi install.rdf  # this will update the zip file with new install.rdf
• Install the xpi in firefox

I have used it a few times and have not faced any problems
