No because I usually don't mind the ads and even find the targeted ads useful sometimes (crazy, I know) ... but I'll go ahead and activate one for when I browse the Disboards!
Edit - right after I posted about the slow site, it improved and got much faster (I did not install an ad blocker). I
did then go ahead and try and ad blocker, and it resolved my neverending-page-loading issue and seems to help w/ speed also. Who knows!
