Mozilla and Yahoo have filed complaints against each other regarding the use of Yahoo as Firefox’s default search engine.
The legal battle started after Mozilla replaced Yahoo with Google.
On 1 December, Yahoo Holdings and Oath filed a complaint against Mozilla – claiming it improperly terminated its agreement with Yahoo.
Mozilla then filed a cross-complaint for breach of contract.
Mozilla said it exercised its contractual right to terminate its agreement with Yahoo, based on a number of factors.
These factors include “doing what’s best for our brand, our effort to provide quality web search, and the broader content experience for our users”.
