In MacOS in the Activity Monitor Google Chrome extensions show as "Google Chrome Helper". These often take up much of the CPU time. Is it possible to determine which tab a given Google Chrome Helper process is running on?
Other people have suggested setting the plug-ins run mode to "Click to play". It seems that this doesn't cover all instances of the helper, since I already have it set to click to play. As you can see from the image below, there are MANY instances of this helper running. Anyway this doesn't get to the heart of the question- which tab is the process running on.
Chrome's built-in Task Manager (accessible from Menu > More tools > Task manager) will show you a per-tab resource utilization.
If case the culprit is extension code or a plug-in running in a normal tab, you won't be able to identify it with only that; extension entries in the Task Manager are only for background pages of extensions.
You may be able to investigate further with Dev Tools profiler.
I have quite a good experience with this "Google Chrome Helper" and how to debug the notorious problems on Mac.
1. CHROME EXTENSION
In this case go to the 3 dots you find on the right upper side of your browser and then More Tools > Extensions, here you can have an overview of all your extensions.
Deactivate all of them and relaunch Chrome.
If the issue is resolved we can now point out that the issue was related to one of your Extension. But what extension? You can now reactivate one by one while you have your Activity Monitor open and see when the "Google Chrome Helper" is trigged.
2. CHROME EXTENSION OR CHROME SYNC
Sometimes you can find the Chrome extension that is draining your CPU but you have to work and keep that Chrome Extension available. Or maybe that Extension is managed by your Company and you cannot disable it.
In this case you have to click on your Chrome account on your browser and sigh out from all of your Accounts.
Now close your browser, reopen it and "Google Chrome Helper" shouldn't bother you at all. Well, this is normal, because you are not signed in. Now Sign in into Gmail but don't never ever click on the "Turn on sync..." button
Now you can also install the Chrome Extension that was giving you pain and you shouldn't experience any problem. Just don't touch that "Turn on sync..." button.
3. I STILL HAVE PROBLEMS
Well, in this case you are facing something I haven't faced myself. The only suggest you I can give you is to debug the issue by yourself. When the CPU is spiking high open the Activity Monitor and target the "Google Chrome Helper", look at that line and take the PID number (in the picture that you can see in the question is 29048).
Now open a terminal and run:
killall -9 29048
This way you have now killed the process itself. Try to spot what has changed in your Chrome: maybe an Extension has been deactivated, maybe a tab was closed, maybe a webpage has become unresponsive. Dig and you will find the solution.

Context: I have three web browsers installed on my Windows 10 computer which are Chrome, Firefox, and Opera.
Problem: Whichever browser I newly open, they all start with this website:http://007eecfcfedlkh.jumpkj.chuairan.com/index.html
How it happened: I clicked a link on a website yesterday and it automatically downloaded several applications and automatically installed themselves without showing any instructions to install them.
Thing I have tried: I have reset the browser On startup setting to open my homepage, but it still opens with the aforementioned weird URL.
Thing that may help: Opera browser is very considerate cause it has this option regarding the On startup setting, which is Ask me when Opera is started by a shortcut specifying an URL.
Analysis and need your help: Usually, I start a browser by clicking on the shortcut in Windows start menu, or the shortcut in desktop. This worked normally until the problem appeared. According to Thing that may help, this hostile URL must reside somewhere. Where can I find this unwelcoming shortcut on my computer? How come this shortcut can attach itself to every web browser on my computer? What is the next step I can do to resolve this problem? Is this kind of a virus?
Usually when that happens, you'll have to:
reset the browser settings (or at least reset the startup websites on settings)
go to the browser .exe, open it's properties and remove any flags that were added on the path.
I think you shoud uninstall these applications first.
I am working on Google Cloud Platform to develop a project in API.AI, I have an integration (in API.AI) with Google Actions (for Google Home or Google Assistant), they provide me to see my progress as real time in web-simulator, that you can find here:
https://developers.google.com/actions/tools/web-simulator
I am trying to START the web-simulator clicking on START button, then I get a window pop-up but after open, it closes, I try and try again but I obtain the same result, I cannot open the web-simulator. I have allowed the popup windows in my browser.
Of course I have completed all steps to start web-simulator...
I don't know what is happening. Someone can help me? Thank you, have a good day.
First, are you using a compatible browser? Try it in Chrome if you're
not already using it, as Chrome is a Google product, and so is the
web simulator.
Next, are you using any Ad-Blockers or
Script-Blockers like NoScript? If so, try disabling them, as they
could interfere with the operation of the tool.
If it still doesn't work, try going to an Incognito Windows by pressing the
three dots button and opening a New Incognito Window. Go to the page, and log
in. This will ensure that no cookies are interfering.
At this point, if you're still having issues, try a different browser.
(Either Firefox or Opera)
I have a web application that uses IIS, but when I try to debug it VS just locks up and gives me the hour glass cursor icon. No browser window opens, nor does an instance pop up in the Task Manager. VS says its Running / not "Not Responding", but I cannot interact with the IDE. Can't Ctrl-Break to stop or anything.
I was able to run it before, and I'm not aware of any system or IIS changes that could cause this. I've disabled source control and I've tried launching the app in both Chrome and IE but it still behaves the exact same way as described above.
Has anyone else encountered this? The only threads I could find just describe general slowness in the IDE but otherwise its functional. The recommended fix was to disable the source control functionality, which as I said I already tried.
I should note that I don't seem to have an issue running & debugging winforms applications. I also just created a web application and was able to launch it in Chrome and get to the homepage. Also, it doesn't make a difference if I have a breakpoint set or not.
This solution has 4 different projects. If I set a different project as the Startup Project, it does run and launches the browser but it just gives me a 'file explorer' sort of view where it just lists the files in that project's directly which is obviously not what I want.
Edit; If I manually open a browser tab, try to navigate to http://localhost/myApplication, VS pops up and asks if I want to attach process w3wp.exe to IIS APPPOOL\myAppPool. If I attach, it opens a new tab in Chrome and my application runs. But unless I do these 2 steps, it does not run.
I am tearing my hair out. I have a complicated Flash player application which I want to run on my local Mac, 10.7.4. I set this up a year or so ago on earlier Mac OS, with earlier Flash players, and sometimes I had to fiddle with global settings, etc, but it always worked. But now flash has decided (sensibly) to handle the security settings surrounding this use of Flash from the local System Preferences. Here's the appropriate screen which should let me tell Flash that I am opening files in the folder:
You can see my desperate attempts to get flash to let me open files in /Users/peter/BTDE2/ etc -- all failing.
Why? How do I get around this? or do I just give up on flash as a horrible bad job...
It appears from the documentation at http://help.adobe.com/en_US/FlashPlayer/LSM/WS6aa5ec234ff3f285139dc56112e3786b68c-7ff0.html#WS6aa5ec234ff3f285139dc56112e3786b68c-7feb that there should be a fix. According to this, there should be a 'Developer Tools' control on the 'Advanced' panel, which gives access to 'Trusted Location' settings. Well, here is the Advanced panel in Flash System Preferences and it shows no such choices. Looks like someone screwed up somewhere.
In the Flash Player panel are you not able to scroll down to reveal the Developer Tools?
When I open a site the loading spinner keeps spinning in the favicon area and I see the 'waiting for site.com' message.
It seems to me like the site has already fully loaded, but evidently not.
How do I check what's still loading?
I'm happy to use Firebug as well if it's easier to see there.
Edit:
Network tab doesn't indicate anything is still loading.
Edit: is there any way to filter network tab to see what's still incomplete vs already completed requests
You can use developer tools (Network tab) for this analysis.
To check what's still loading, first open the Developer Tools (press F12) and switch to the Network tab. Then load the site; you'll see all the requests the page makes. From there, you'll be able to see which aren't yet done.
