I installed two browser plugins successfully (Adblock and Useragentswitcher) but cannot update adblock list, resp. set user agent.
In the latter case on the site http://browser-extras.garage.maemo.org/news/8/
Bioth are listed in the components list.
there is a link

"Get the installer here and check it by yourself. Remember to restart your MicroB browser twice and then configure it according to your preferences by clicking here or manually loading chrome://useragentswitcher/content/config.html. "

I did this (click on 'here' or 'chrome...') but nothing happened.

What am I doing wrong ?
