I was browsing Digital Media Minute and the latest entry is a how-to for removing GMail’s ads. Well, not actually removing them but hiding them. While many people bitch and moan about GMailFS and GMail Drive going against the intentions of GMail, I am going to go out on a limb and say that Google might have a problem with this. Of course, this is a nice little piece of CSS wizardry. While I do not condone such activity and would not consider doing it myself, you might want take a look at the code.

Do you find the text ads in GMail to be annoying? If you do, you can use Firefox to hide the ads from displaying.

This trick uses CSS and the Firefox configuration file named userContent.css . Before we start modifying our userContent.css file, I would recommend that you install an extension named ChromeEdit that simplifies the process of modifying your Firefox configuration files. So before you enter the CSS code listed below, go and install this extension (note: you?ll need to restart your browser after installation, so you may want to bookmark this page).
