A developer of web browser software that allows parents to control their children’s use of the internet has secured additional funding. Glubble raised $3 million from existing investors including Morten Lund, one of the first investors in voice-over-internet business Skype.

Lund and the other founding investors in Glubble are all fathers of young children. The company was started in 2006 as a personal project by father-of-two Ian Hayward.

Glubble’s software is free and works with the Firefox internet browser from developer Mozilla. It restricts internet access for children under 12 to websites their parents have approved in advance.

According to the company, more than 100,000 families have downloaded the software.

Glubble intends to make money by developing paid-for premium services, which it plans to launch later in the year.
