When I open new tab I read "chrome://new tab" - google-chrome

Tomorrow when I open new tab I read "chrome://new tab". What is that? is dangerous? How can I remove this?

Anything that starts with "chrome://" comes from the browser itself rather than another website. So don't worry about it it shouldn't bother you at all.

The url "chrome://newtab" means a new tab opened by chrome itself.
It is secure and configurable which can be modified in Settings -> On startup.

reset chrome media engagement score

I know that Chrome 66 introduced some restrictions when autoplaying a video (in HTML5).
In some cases the autoplay is supported. One of the conditions to support autoplay is when the user has watched a video in the domain before or something similar. So Chrome is keeping an internal score for each site. This score can be checked in chrome://media-engagement.
But now my problem is that for testing I have not figured it out a simple way to reset this score. So I can not properly test it for the new users.
Any idea?
A quick throwaway solution to have a new window with empty MEI data is to open a "Guest window" by clicking the user avatar and choosing "Open Guest window" button.
The easiest way I found to test using a clean score is to create a new profile in Chrome:
1- At the top right of Chrome, click the button with your name or People People.
2- Click Manage people.
3- Click Add person.
4- Click Save. A new window will open and ask you to sign in.
It is not recommended to manually make changes to your profile folder, but this worked for me.
Go to chrome://version/ and note the Profile Path
Close Chrome
Open the Preferences file in your profile folder with a text editor.
Delete the media_engagement entry.
Go to chrome://media-engagement to verify that everything has been cleared.
Alternatively you can just remove the Preferences file altogether but this removes a bunch of other things as well.
You can also clean MEI by clearing browsing history:
Click Ctrl+Shift+Del or navigate to chrome://settings/clearBrowserData
Go to Advanced > All time
tick Browsing history
Click Clear data
Navigate to chrome://media-engagement to verify
BTW. Note that notably going into incognito mode doesn't reset MEI; the MEI data are copied from regular session when opening first incognito tab (and then lives on its own until incognito session is closed).

Netbeans Chrome - clear browsing data

I'm using Netbeans to develop an HTML / CSS / Javascript / PHP app. I find that when I make HTML changes, I need to 'clear browsing data' in Chrome before the changes show. I suspect it's actually the 'cached images and files' that need to be cleared rather than the browsing history. Can someone explain why is this? And is there a way to auto clear history when launching the browser from Netbeans? It gets a little tedious when testing the app to have to clear browsing history all the time.
Try using Ctrl (or Cmd) + Shift + R to make a hard refresh. If needed, you can do this:
Open the Dev Tools.
Click and Hold the Reload Button.
Click on the third option.
Note: You can use Incognito Window, which doesn't cache much often.

Chrome load tab without selecting it

The question is opposite to this one.
Say I open link in a new tab. Currently it is opened, but not loaded. It starts loading only when I select it. I want so that I open a lot of links on a page and those tabs start loading without need to be selected.
Furthermore, there is another problem. When I open link, select that tab, tab is loaded. Then I go to another tab, do something there and return to the first tab. So this tab starts to reload again.
How to fix this?
My version of Chrome is - 48.0.2564.116. It starts to happen recently.
If you are using (in settings) "continue where you left off" then switch to "Open specific page or set of pages" try it there, then switch back
The answer is https://superuser.com/questions/1048029/disable-auto-refresh-tabs-in-chrome-desktop#answer-1049471. Shorter, the flag #automatic-tab-discarding needs to be disabled on chrome://flags.

When should links open in new tab/window?

When exactly links should open in a new tab/window? I find that some of the actions which require certain operations in a new tab/window can be done on the same page using modal windows and then refreshing the same page to show the updated contents.
A couple of google searches gave me the following results:
Why external links should open in new tabs?
When if ever should links be opened in a new window?
Is there ever a good reason to force opening a new browser window?
Should links open in new windows?
Forcing links to open in new windows: an argument that should have ended 15 years ago
Some suggest that in case of external links they should be opened in a new tab/window, some suggest that they should be opened on the same page for simplified user control. Both of them sound correct in their own ways. Isn't there some sort of generalization? Or are there any particular situations where we cannot do without links opening in a new tab/window?
In other words, what are the situations where a link should open in a new tab/window OR in the same page (taking into account that modal windows are implemented frequently these days)?
Having external links opened in a new tab is better and done more often so that when you have a user surfing your site and clicks on an external link he doesn't have to go back but simply just needs to close that tab and can continuous surfing your site.
You have to bare in mind that not ever internet user knows how to work with a browser like you do (Still many lesser-intelligent people on the net).

How to remove all breakpoints in one step in Google Chrome?

How to remove all breakpoints in one step in Google Chrome? Using version 11.
[update]
There is now a feature request for this.
[update]
The feature request is closed (Dec 2011)!
This is now possible in Sources tab of Chrome Developer Tools.
Please see screen grab below and right click within the "Breakpoints" section of the left window.
Since recently (Chrome 18), you can right-click any breakpoint in the Breakpoints pane and voila! The "Remove All JavaScript Breakpoints" popup menu item!
Chrome Devtools crashed everytime I tried to access the Sources panel because of a breakpoint on a minified Javascript file.
To remove all breakpoints without access to the interface, you can do the following:
Open inspector-on-inspector : undock first inspector and hit ctrl+shift+i to open the second
On the inspector-on-inspector console, execute the following:
window.localStorage.breakpoints = [];
Close the inspectors and reload the page. Now the breakpoints are gone.
Under Sources, you can click button marked with red on picture below or use shortcut Ctrl + F8 just like tool tip is showing (activate / deactivate breakpoints). A little bit lower under 'Breakpoints' you will see all your breakpoints. If you choose to disable all, they will be grayed out.
solution here.
To purge all breakpoints open inspector on inspector (undock first
inspector and hit ctrl-shift-I to open the second) and run
"WebInspector.settings.domBreakpoints.set([])" in second inspector's
console.
new Tabs; Ctrl+Shift+J to Console; Access URL
Open the Chrome task manager and end the tab page.
Ctrl+Shift+J to Application -> Service Workers (Offiline) -> Refresh
to Sources Cancel Breakpoint
Success
Another option is to de-activate all break points using:
Ctrl + F8
In my case Uninstall and new installation of Chrome was without any success.
Also window.localStorage.clear() did not help.
My "last chance solution" is to remove entire directory where Chrome is storing its data.
First turn off your Chrome.
Then look at this path "c:\Users\ {your_user} \AppData\Local\Google\Chrome\User Data\Default\Local Storage\". Here try to delete all what is in this directory.
You can also clear all inspector settings and reload the inspector. It helped me with fantom breakpoint I could not remove in any other way. Open inspector and go to Preferences -> Sync -> Restore defaults and reload (at the bottom).
Step 1: Go to Developer tools and expand Breakpoint section
Step 2: Right click on expanded area of breakpint and there will be many options lik
