Hello,
I'm continuing to get this alert at the top of Safari.
This webpage is using significant energy. Closing it may improve the responsiveness of your Mac.
How do I get rid of it?
I'm running macOS High Sierra on my MacBook Air. Version 10.13.4
Thank you,

If the above doesn't work, Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/com.apple.Safari/Cache.db and move it to the trash.
Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

If that doesn't work, try running this program in your normal user account , then copy and paste the output in a reply. The program was created by etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read. On the screen with Options, please open Options and check the bottom 2 boxes before running. Click “Share Report” button in the toolbar, select “Copy Report” and then paste into a reply. This will show what is running on your computer. No personal information is shown.
Thank you for this. I actually did most of this when I first looked for a thread re this error. I didn't find my exact notice since mine didn't say the page was reloaded, but I followed instructions and removed caches folder, caches.db file, Safari folder, history files, all in safe mode and restarted and ran the etrecheck, but continued to get the notice. Quitting Safari, so fare seems to have done the trick. I'll keep an eye out.
Thank you for your help! I truly appreciate it.

I was suggesting you uninstall it. The uninstaller sometimes leaves file behind and those two applications can help you find/remove the files.
Try disabling the extensions in Safari/Preferences/Extensions.
Hi Eric,
I'm unsure what any of these options will do for me. I just want to get rid of the notification. Why is it popping up when I use Safari and how do I get rid to it? I don't understand why I need to set up another admin account, or what using Safe Mode will do.
Thank you,
Tim Key
For trying another admin user account, the intent is to see if it is specific to one account or a system wide problem. This account can be deleted later. If it is a system wide problem, one answer might be to reinstall the OS.
The Safe Mode will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem.
Hi. I am having the same problem but Force Quit will not stop the same message appearing next time I'm on the page.
Does anyone know what is causing the message to appear and how does one stop it if they want to? The warning is not causing detrimental effect but it is distracting and annoying and there seems no way to stop it appearing.
I have been getting the same warning for some time now. Have also tried all the above suggestions and it's just a waste of time and inconvenient - clearing history and cookies etc is annoying.
I think this is a problem Apple has introduced in a recent patch and needs Apple to investigate and isolate.
I even went to the trouble of rebuilding my MacBook and the problem just returns.
Over to Apple me thinks ........ based on historical reactions from them, we can expect to have this problem for a long time.
I must say I do not get this warning when I use Google Chrome, so Safari browser must be the issue.
I agree. All of these solution all assume that indeed, this website is using significant memory and we want to stop that use of memory. In probably 99% of the cases where this message pops up and disrupts our browsing, we know where we are, and we want to be there for whatever reason, and in probably every case we don't care that the website is using a lot of memory. Let me decide if I want to deal with a choppy messy website. I already know it's chopped up and jumping all over the place. I don't understand the purpose of this message at all. I hate Google, but it looks like I'm going to have to start using Chrome, Safari is becoming a mess.
You are welcome.
So, the reported issue is back this morning. After doing everything you all said to do. Anything else?
Try posting an Etrecheck report.
Got it. I have successfully uninstalled the clean my mac cache and I'm still getting the same notification in Safari.
