Yahoo’s new owner Oath — which, in turn, is owned by telecom giant Verizon — is now in a legal battle with browser company Mozilla over a search deal that was struck by former Yahoo CEO Marissa Mayer.
Last week, Yahoo Holdings and Oath filed a complaint against Mozilla, alleging that it improperly terminated an agreement between Mozilla and Yahoo. Now, Mozilla just filed a cross-complaint, claiming breach of contract.
Mozilla announced that it was going back to Google, which had been its longtime search provider, in mid-November in the U.S., Canada, Hong Kong and Taiwan. Google had remained its partner in other countries and Mozilla also has deals with Yandex in Russia and Baidu in China. At the time, it also announced a new browser, Firefox Quantum.
