Chrome Developer Tools not displaying (Version 51.0.2704.84 (64-bit)) - google-chrome

I'm no longer able to access my Developer Tools in Mac Chrome (Version 51.0.2704.84 (64-bit)). This is the latest update for Chrome. CMD-OPTION-I and View > Developer > Developer Tools provides no result.
Is anyone else having this issue? Any ideas how to fix?

Try go to ~/Library/Application Support/Google/Chrome/Default\Local Storage and delete these two files :
chrome-devtools_devtools_0.localstorage
chrome-devtools_devtools_0.localstorage-journal
Or purge all your Google Chrome User Data and reinstall Chrome.

To fix this issue, I did the following:
Made a backup of /Users//Library/Application Support/Google/Chrome/Default.
Delete the Chrome App
Deleted the root Chrome folder /Users//Library/Application Support/Google/Chrome/
Downloaded and reinstalled the latest version of Chrome (Tried a simple update before previous steps, but didn't work)
Removed defaults from the new install
Copied back up of default content into new Default folder
Dev tools are now functioning again.

VS2017 Chrome Browser Debugger "Object reference not set to the instance of an object"

I am having trouble debugging my web project using the Chrome Browser. I can only use IE to do my debugging. I did some "googling" to resolve this problem, and came across a few Microsoft threads that said to update to the latest version of VS2017, which I did. I use version 15.9.13 and Visual Studio 2017 tells me I am "up to date" when I check for further updates.
When I first updated VS 2017, it started working, and I could debug using Chrome (finally!). But now it has stopped working again.
I saw in other threads where people suggested deleting the .vs folder, which I did, but had no luck with that.
Google Chrome is up to date at Version 75.0.3770.100
I debug and run my application as "Administrator" so that shouldn't be the problem either. I also close all browsers before running the debugger, so Chrome isn't running elsewhere when I try to debug.
Is there any explanation why Chrome cannot launch when using debugger? I would really like to use Chrome because of it's superior "dev tools" and inspection tools. Any suggestions? Was sad to have it working only one day.
Having configured the same environment like yours(VS version and Chrome version) but can't reproduce the issue.I would think if something is broken in VS or maybe third-party extension is the causes this issue.
Please try:
VS repair and a reinstall of Chrome(don't forget to backup the bookmarks)
Uninstall or disable third-party vs extensions, this won't take effect until restart vs
Navigate to %LocalAppData%\Microsoft\VisualStudio\15.xxx directory, delete all ComponentModelCache folders in all 15.xxx folders.
Open your project in vs, changed the target browser from Chrome to IE. Then F5 and wait until it is finish. Stop it and change the browser back to Chrome. After that the error disappeared.
Also, create a new asp.net web app and debug it with Chrome browser to check if the issue persists. Hope it helps.

explicitly-allowed-ports not working in latest google chrome v. 72.0.3626.109

We have few local sites with unsafe ports i.e. 100,101,102,103. Those were working fine on google chrome with explicitly-allowed-ports in the shortcut target. Suddenly they have stopped working for new update version of chrome v. 72.0.3626.109.
I am not able to find any solution to it. Even if I install the old version of chrome it gets updated to the new one. Can you please guide me what to do. I cant change the mapping of websites as there are limitations. Please guide.
This bug was already found in the Canary branch:

Temporary solution is to disable the "Enable Network Service" option in the chrome://flags settings

How can I downgrade to Chrome 42.0.2311.90?

Google Chrome on my machine recently got updated to v44.
I'm working with Selenium WebDriver on Chrome and as soon as I updated Chrome, all my tests went dead. I use Chromedriver v2.16. My partner's PC has Chrome v42.0.2311.90 and Chromedriver v2.16. And tests run fine on his machine. Now, based on this I'm pretty sure the problem is probably not with Chromedriver.
So, how can I downgrade to Chrome 42.0.2311.90?
I've tried using an offline installer from here:
Google Chrome Alternate Offline Installer
But this always gives me the latest version to install i.e. v44.
The release that I need can be found here:
Google Chrome v42.0.2311.90 Stable Channel Update
Uninstall your current chrome version.
Remove all Chrome data for current version from: C:\Users\username\AppData\Local\Google\Chrome
Download your particular version from chrome_installer.
Disable chrome updates using instructions given on this link.
Following steps help you to install your desired google chrome version :
1 - Uninstall your current google chrome version.
2 - Download your desired google chrome version from here : Google Chrome Download
3 - Restart PC once so if any registry or temp file stored of previous google chrome then it will get refresh.
4 - Install your downloaded google chrome. And then turn off automatic chrome update.
I struggled with this same problem on Mac, trying to downgrade, and stay downgraded from Chrome 53 to 52 due to a serious bug affecting webaudio.
None of the other recommendation appear to apply any more (or on Mac OS X at least). The app attempts to upgrade itself and there doesn't be a way to configure that in a "Chrome-friendly" way.
Eventually I resorted to force...
Close and uninstall Chrome
Edit your /etc/hosts file to prevent update checks from working by overriding the DNS entry:
0.0.0.0 tools.google.com
Find and download an old release. This is left as an exercise, this was actually hard and fraught with fear of bad binaries. I was able to cross-reference MD5s from one site that didn't have downloads with another that had downloads.
Install and run the older version
Important: Check the "About" page, and point and laugh at Chrome's attempts to check in.
This is how you can use an older chrome version "in general":
Uninstall your current chrome
Install the chrome version you desire
DO NOT open chrome!! after installation
Instead disable auto-updates like here or here
Only then may you work with your desired chrome browser version
As for how to get a specific older version:
You need to google, search forums or try sites like this. It's just "grunt work" to find the version you are looking for. If you're extremely unlucky, the very version you need might even not be around any more.
If you are running on a windows machine you can leverage the package manager chocolatey, this is how we I'm doing it from Jenkins, we call a powershell that uninstalls a previous version and install a specific one: From a powershell ide script window, you need to have installed the modules for chocolatey that is a small price to pay for a lot of benefit:
choco install googlechrome --version 62.0.3202.94 -y
Then to prevent Chrome to self update I am performing this steps:
1. Verify Chrome's current version.
(Get-Item (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\chrome.exe').'(Default)').VersionInfo
Install the version I'm aiming for:
choco install googlechrome --version 62.0.3202.94 -y
You can look for available versions here:
https://chocolatey.org/packages/GoogleChrome
(Find Version History Section)
Kill GoogleCrashHandler.exe in any of its variants 32 or 64 bits or both.
Delete the Directories
C:\Program Files (x86)\Google\Update and
C:\Program Files (x86)\Google\CrashReporter
You will loose the ability to auto update (which is the whole purpose right) and
you will loose the ability to send crash reports and piggy back on that executable to update against your will whenever google deems convenient.

Telerik Framework does not see Google Chrome

To test the use NUnit + Telerik Framework
Browser: Google Chrome v24 + standard extension of Telerik
When you run the test - an error "Failed SetUp: System.IO.FileNotFoundException: Chrome browser is not installed on this machine TearDown: System.NullReferenc"
Reinstall Telerik and Google Chrome did not help.
Tell me, please, how to solve the problem?
Translated by Google Translate.
Issue resolved.
Cause of error - Telerik does not work with Google Chrome v.24
Installed Chrome v.20 - it worked
UPD:
After the automatic browser update to version 24 - Telerik is working correctly
Re-install chrome, and do not say yes to the UAC prompt. What is most likely happening if chrome was installed with admin privileges so it installed to program files. Telerik's testing framework expects chrome to be installed in %appdata%. By saying no to the UAC prompt and yes to the install without admin prompt chrome will revert back to installing in %appdata%

Does Chrome browser build verion 4.0.249.78 still support user script?

I had a couple of user script that worked in version 3.5 by adding command line option --enable-user-script, after I upgraded to version 4.0, all those scripts stop working. Chrome browser is promoting its extension, some of user script can be replace by a chrome extension. Can anybody confirm if latest chrome browser stop supporting user script?
The latest Chrome builds allow you to install a user script as an extension with no modification. Just open the .user.js in the browser.
