I never use Blochair website, or should I say almost never, because sometimes I click on link that someone sent me from blockchair.
Much better and cleaner alternative in my opinion is mempool.space, and it's not supporting bunch of shitcoins like it's competition.
One more good thing, mempool.space is fully open source, you can run it with your own node and you don't have to trust any third party.

I am using uBlock Origin and I can't even imagine browsing internet without it.
Recently I had to install new operating system on one laptop and test how it works including internet browsing, it was painful experience to do it without ad blocker... funny thing is that most people don't use any ad blockers believe it or not
