Mozilla has allowed Avast and AVG’s extensions back on the Firefox addon store after Avast reduced the amount of tracking data being sent back to its servers.
At the beginning of December, Mozilla removed the Avast Online Security, AVG Online Security, Avast SafePrice and AVG SafePrice extensions from Firefox after AdBlock Plus’ creator Wladimir Palant discovered that they were sending a large amount of user tracking data back to Avast.
