Apparently there is a vulnerability in Jaxx that hackers used to steal $400,000 of coins held in their wallets. I wouldn't consider using it unless that gets fixed.
Reports are surfacing of a vulnerability in Jaxx wallet leading to at least $400,000 customer funds being stolen.
A report on the insufficient wallet backup phrase storage methods this weekend has now updated to include reports that hackers are already exploiting the problem to steal cryptocurrency from users.

After you read the whole article[1], you will come up with the decision of not using this wallet again (most likely). Basically, they have no plans to alter or change the security setup of their wallet. I'd recommend everyone to either stop using this wallet or simply stop storing large amounts.
