I think its impossible to recover the cookies and cache of your browser except if you login in chrome you can be automatically save almost all your bookmarks and cookies and cache to sync automatically to your new browser but if are not logging in your email it is impossible to recover your account there if you forgot your seeds.. only seeds is one of the key to recover your wallet anytime anywhere..
Thanks for your reply.
i'm gonna try though.
I have 17k wagerr on this wallet + a few waves.
Maybe in the future with the quantic computers lol
Its nearly impossible to recover once those cookies are gone since you cant really access it without those seeds. Have you tried out already the steps been said above ^ Its worth to give a try even youre on safari, you might able to see those folders listed on the system and might resolved your problem.
You do have lots of coin there and such a waste for them to lose up.
