Didn’t had to much to do with Adsense until I started this blog. Now, because I have a “adsense optimized” theme I decided to play around with some ads and experiment how the content influence them. Soon I felt the need to preview offline kind of ads I would get displayed. Google has some tool, but works only with IE and Windows. Not that tasty for me, as I like my web development environment on Ubuntu too much.
Fortunately I found a Firefox plug-in here. It installs straight forward as a Mozilla extension and works on every OS where Firefox can run. After installation it adds a new Menu to the Firefox menu bar.

One can preview 8 different types of ads:
* Leaderboard (728×90)
* Banner (468×60)
* Button (125×125)
* Skyscraper (120×600)
* Wide Skyscraper (160×600)
* Square (250×250)
* Medium Rectangle (300×250)
* Large Rectangle (336×280)
Ads in preview won’t be exactly the same as on the online site, as it uses test ads, so it won’t harm the Adwords owners, but it will give you a pretty good idea of what kind of ads you will receive. Please also note that in case you use a cms system, the difference may be slightly greater.
