Google Chrome v.75
Google Canary v.78
chrome://flags "#site-isolation-trial-opt-out" - disabled
So the problem is that browser crashes right after attempt to open developer tools with changed flag.
I tried to switch between original chrome version to canary but catch up the same problem
I expected the developer tools working with changed any of chrome://flags
On my school chromebook developer tools just got disabled or something.
When i right click to inspect an element, the "inspect" button is grayed out and if i click the options button in the top right, go down to more tools the developer tools button is grayed out there too.
Does anyone have any idea what is happening and why it is happening?
(Developer mode is enabled on my chromebook)
On a Chromebook, Chrome Developer Tools is enabled/disabled through Chrome Policies, which is maintained by the Chrome Management Console as part of a Google Work account. In this case, the policy is DeveloperToolsDisabled.
In Windows, it is possible to enable/disable it in the registry, and there is possibly a Preferences file in OSX.
I'm afraid you would need to speak to your school's IT department about this, as they are the only ones with access to these policies.
Is it possible to open Chrome Developer Tools to inspect a Chrome App ?
All debuggable targets are listed under chrome://inspect/. See the 'Apps' tab.
I managed to do it by following instructions to debug postman chrome app:
Go to chrome://flags/
Search for Debugging for packed apps
Enable this flag
Restart chrome
Then go to your app, right-click anywhere inside of it, and click on the option menu inspect.
To open it by context menu, enable at chrome://flags/#debug-packed-apps
If the app blocks the context menu, find it at chrome://extensions (developer mode) or the Apps and Extensions Developer Tool.
I am using chrome version 36+
according to this page, I should be able to allow custom themes using the following instructions:
Installation Instructions
Add this theme
Goto chrome://flags and Enable Developer Tools experiments.
Open developer tools settings, select Experiments tab, and check 'Allow custom UI themes'.
Reload devtools.
I do not see such a tab in the dev tools settings. I see only 'general', 'workspace', and 'shortcuts'
These are some simple steps to follow, hope it will be helpful.
Open a new chrome tab, type chrome://flags
Find, "Enable Developer Tools experiments." using ctrl/cmd+f or simply searching for it by scrolling down the page.
Click the "enable" link
Click on "Relaunch Now" at the bottom of the page.
After restarting Chrome, open DevTools, DevTools settings, and select the experiments tab.
Now select the experiment you want (e.g. "Allow custom UI themes").
You need to reload devtools after: Alt-R will reload devtools itself, or you can just close and reopen it.
To get to the Dev Tools Experiments area you have to click on the gear icon in the inspector.
If still not working you should go to:
chrome://extensions/
And click the 'Enable' checkbox for the DevTools extension you wish to enable.
Had the same issue,
I found I was going to browser settings which is NOT where you should be going to ,
You need to go to developer setting .
i.e right click>inspect element> dev tools
You need to restart the browser after changing the flag at chrome://flags
I found it. There is a checkbox under experiments tab:
Allow custom UI themes
Restart chrome just not means to close the chrome and then open it. you should click the 'Relaunch Now' button of the flags tab. and then it's work for me.
loislo's answer is absolutely right (You need to restart the browser after changing the flag at chrome://flags). But notice that your chrome can work in the background. Go to the tray, look for the chrome icon and exit.
Navigate to chrome://flags/
Find and enable Developer Tools experiments Mac, Windows, Linux, Chrome OS
Relaunch Chrome, open develop tool, setting, you will see experiments tab.
My Chrome version: Version 61.0.3163.100
2022 update: There doesn't seem to be any option in chrome://flags but there is an option:
devtools > settings > experiments > Allow extensions to load custom stylesheets
Is there a firefox equivalent of chrome's inspector "Resources" tab? I am trying to delete something from localStorage for a web site in firefox but it won't go, and the standard settings->clear cahce don't affect it at all.
Check for this:
Enter about:cache in browser address and see "Offline cache device" section.
Firefox storage inspector lets you see local storage.
This seems to be the closest equivalent to the chrome resource tab.
I had to explicitly enable the tab in the Firefox Develop Tools Options to get it to show.
