Hi Guys

Ever since updating to Mojave Safari has been so slow. It is now at the point where if I type an address in the address bar it take up to ten seconds to register. Anyone else having this problem?

Ive attached a photo to show the lag white screen

Yup that's happened to me too. Using Chrome for now because it became pretty rough.

Something that sped it up was turning off the new tracking block technology... but it's still slower than I was used to in High Sierra.

When I first installed Mojave everything was fine but in the last week Safari has become sluggish on both my iMac and my MacBook. Facebook seems to be the worst offender with it being slow to scroll and constantly giving me beach balls.

My Safari was taking 5-10 seconds for a website to appear that would appear instantly in Chrome & Firefox. I turned off the (new) Adblock Plus Extension I'd installed and that restored it to normal speeds. Seems these new app extensions are considerably slower a blocking content than the previous Safari extensions under High Sierra and earlier were.

Any suggestions for other ad blockers?

That may very well be the issue. I am going to turn it off and see if that improves things. Gotta start somewhere I guess.

IF it is an Adblock thing, then I hope they get it sorted.
[doublepost=1539776160][/doublepost]And to confirm that within minutes of disabling Adblock, and restarting Safari it appears I am back to what is normal speed. So it would appear Adblock is the issue here.

Same here, Safari working pretty slow on a 15" MacBook Pro TB (2016) since the Mojave update. Hope it gets solved soon..!

I am having the same problem on Safari on High Sierra. Amazon would hardly load as well as other websites. I have AdBlock Plus. Turned it off and now everything is faster. Bummer.

I suspect, that Apple slows down third party extensions on purpose - for whatever reason. My uBlock Origin install worked perfectly, but a couple of months ago Safari started nagging to remove it and now it will remove the extension itself without my authorization on each Safari update. I can manually reinstall without problems, but this is really annoying and not acceptable at all.

Firefox with several security related extensions enabled is now much faster for me than barebone Safari.

same slow speed for me. Chrome is fine. Using ad blocker. Will try wiper as suggested. Was thinking of rolling back to High Sierra.

Anyone else ?

I replaced Adblock Plus years ago; this isn't necessarily an Ad-block issue. Ever since upgrading to Mojave, I have noticed that Web content in general is slower—both under Safari and Firefox. Simply typing a comment within, say, is more laborious now, as there's quite a bit of lag associated with it. Video playback also seems to be less fluid. Not sure what the heck Apple did.

Yep, it is slow as a snail for me, especially since 10.14.1.

To the point of being frustrating. I might start looking for alternatives until Apple decides to fix this mess.

I am on Sierra and I was having the same problems with The latest version of Safari.
The performance has improved by removing ad-block plus and replacing with another one, if I remember well called adblock (I am writing this from my iPad).
I think this is a Safari issue, not a Mojave one.
