Remove Echofon Ads

How to
Remove Advertisements from
Echofon for Firefox

Install Echofon 2.4 or later and restart Firefox afterwards.

Browse the following path on your system:

"C:\Users\[USER]\AppData\Roaming\Mozilla\Firefox\Profiles\[PROFILE_ID].default\chrome"

This is the standard location of your Firefox Profile on Windows 7/Vista. Look up the right location of your profile on other operating systems if necessary.
If the "chrome" folder does not exist yet, create it.

Create a new textfile inside the "chrome" folder and rename it to "userChrome.css".
Make sure the file extension gets applied properly!
Open it with a text editor like notepad and insert the following three lines:

#echofon-ad-unit {
display: none !important;
}

If you're having trouble preparing the "userChrome.css"-file you may download this one:

Just copy it into the path mentioned above.

Save the file and restart Firefox. If you've done it properly, the ads should now be gone from your echofon extension.
