I dont know how anyone could take mozilla seriously after they integrated google analytics into it about 10 years ago for no reason I can fathom. It immediately made me think somethings off, and I never used it again.
Instead I thought screw it and just went nuts deep into chrome, atleast it was more functional.
ps - ( apparently mozilla took it out sometime later , but to me the damage to its reputation was done)
And so switching to a browser created by the world's biggest advertising company is your solution? Interesting
