Safari 12 doesn't support the Java 8/10 plugin any more. Just says 'unsupported plugin'. Safari 10 & 11 required you to approve each website using Java, but at least it worked.

Pretty much means there are no Java plugin capable browsers (Personally, I don't care, but my company still has Java sites that they haven't updated with HTML5 sites).
 
This also breaks JSBlocker, which is the only tool I'm aware of that prevents canvas fingerprinting. Killing these invaluable privacy protections makes this new Safari much worse for anyone who was already taking steps to protect themselves. Shame on Apple.
Ghostery does that too. Canvas fingerprinting was scary when it was new, several years ago, nowadays countering it has become much possible.

I use AdGuard (standalone app, paid) - probably why I'm not having any problems. I don't use any browser extensions that block ads. I know on my iPhone it does a VPN to remove ads.
 
Has anyone else experiencing longer loading times, like webpages loading as you scroll down? Before the update Macrumors site seemed to load for me all at once so if I scrolled down everything was already there. Now when I visit any site when I scroll down to continue reading it appears to be a blank page and I have to wait a few seconds for it to load.

Same issues here.

Safari 12 tries to coerce you into deleting old Adblocker addons (claim they slow down Safari, which I don't believe), so you delete it and then realise there are no working Adblockers with whitelist-function in the App Store for free anymore. Hmm, not cool.

There are a couple of free Adblockers in the App Store. I searched 'Adblock' and there is Adblock 1.9.1 which has a whitelist option.
 
Hmm. The new version of Safari seems to think that AdGuard will slow down my web browsing.

This is an Apple-approved extension that's right on their site. Why do they think it will slow down the browser?
Had the same issue. Extension got disabled right after installing the new Safari and needed to be manually re-enabled (with all the warnings etc.). Is there any ad-blocker extensions that doesn't supposedly 'slow down' my web browsing? AdGuard was already using Safari's native Content Blocking API...

This happened to me too. Apparently AdBlock has an app in the app store now that functions the same. I guess they got bullied by apple as supposedly apple is trying to rid of 3rd party safari extensions.

Happened to me. Got the message that AdBlock was slowing down my browsing even though it wasn't this bad before the update. I just downloaded Adblock from the app store and KaBlock or w.e. its called. Works fine now
 
Favicons are disabled by default. Go to the Preferences --> Tabs and check Show Website Icons in tabs.

uBlock Origin and Ghostery got disabled, and I got the dialogue window that they are now in the App Store, like all other extensions. However, this is not true. There is high chance you are not gonna find the extension you need on the App Store.

Going to Safari Extensions also takes you to the App Store, so you cannot enable your old extensions from there. To make your old extensions work, what you need to do is go to the Preferences --> Extensions, and enable your extensions from there.

I got the first taste of this in Safari Tech Preview, so I knew this was coming.

Nice troubleshooting
 
I really don't like the direction Apple is taking with this. First, it disabled my ABP which was working great for me and won't allow me to install, forcing to go through the MAS which has a dismal selection of adblockers. And Safari 12 in general is definitely slower than 11 was, in a very noticeable way. I wish I hadn't updated.

I don't understand why you guys having issue. I have updated to 12 then yes i did get message saying extension is disabled but then i just went and enabled it. I get why apple is doing this. Dev's just need to stop slacking and update the apps
 
Uninstalled uBlock Origin after updating to Safari 12; but it appears Apple doesn't prevent you from (re-)installing it - they just warn you it will "slow down Safari". Ignore that and you're golden, it would seem.

I'll be curious to see if the are more forceful about this as time progresses.

I don't want those ugly favicons in my pinned tabs. Anyone know how to get back those monochrome autogenerated(?) favicons used in the previous version? Even if I disable favicons in tabs, they're still visible in my pinned tabs.

Same here. I hope they haven't removed the old option of having the simpler icons. These ones are a real eyesore.

It makes sense but I didn't realize that the Safari Extension 'uBlock Origin' was able to see my usernames and passwords...

I wonder if it's finally fully compatible with Facebook since it hasn't been for almost 1 YEAR!

Facebook doesn't seem to care. Apple apparently not much either.

Since no one else answered, I can now answer my own question.

Still not fully Facebook feature compatible with other browsers. HELLO APPLE!

I mean 2 other browsers can do stuff Safari cannot do. When are they going to get it?
