Unable to set/edit cookies in Chrome

I realised today, that I'm no longer able to edit or create new cookies in Chrome. It works in Firefox and Safari as of now.
I go to Developer Tools > Applications > Cookies and try to change their values. The line turns red and if I click out, it resets to what it was.
Do I have to deactivate something somewhere?

yep, solved by:
search in chrome settings for flags by entering in the url field chrome://flags
search Partitioned cookies and set it to enable
Restart chrome (might need to refresh the page after the restart)

Chrome Dev Tools stops at breakpoint even when breakpoints are deactivated

I encountered an issue while debugging Javascript in the Dev Tools in Chrome.
Even when I have deactivated the breakpoints from the button, it still stops at them.
like this
I haven't enabled the "Pause on exceptions" button and the only thing that works is when I disable the breakpoints one by one (not having 'tick' on them).
disabled breakpoint
I noticed that this appeared in a week or so.
My browser is Version 78.0.3904.108 (Official Build) (64-bit)

It happened to me when I had another browser tab open on the same domain and the dev tool was open in that other tab too.
in that case you need to decative the debugger in both tabs or better close the other tab.

Edit: The issue is gone now, with the last update from chrome.

Chrome automatically blocks javascript when open Developer (F12)

I have a problem with Chrome running on my PC.
Websites are running fine on Chrome, but whenever I open developer tools (F12), Chrome blocks that site's javascript. Keep the developer tools opened, and refresh the page (F5), Chrome loads the site with without any scripts.
This happens to all websites.
Incognito mode doesn't encounter the issue.
I checked settings in Chrome and it allows JS.
I tried to disable extensions, doesn't work.
I re-installed Chrome, doesn't work.
I tried to run using a different Chrome user account. Work fine.
But I am a developer so I don't want to use incognito mode all the time or use different account.
Please help,
Hoang
Edit:
* Add screenshot

Select settings from "Inspect element window" and untick the "disable Javascript" check box

Internet Explorer Developer Tools how to preserve log upon navigation?

I'm looking for the way to log stuff in Internet Explorer Developer Console that preserve page refresh.
Under Google Chrome and Firefox's Firebug it's an option for that, but I could not find it under IE.
I'm using IE 9.

In IE Developer Cosole go to Tools -> Clear Entries on Navigate and uncheck what you want to stay in log.

In Internet Explorer 11 there is now a button ("Clear entries on navigate") which one must toggle for enabling/disabling the IE to clear the network logs on navigation or even http redirect.
MSDN: http://msdn.microsoft.com/en-us/library/ie/dn255004(v=vs.85).aspx

In Internet Explorer 11 there is a button that you can click to delete or preserve console logs on navigation. If you want to preserve your console logs, then just untick the button (highlighted red in my screenshot).

Clear entries on navigate is a toggle switch with on and off states. When in the off state, network traffic for a window or tab is recorded continuously as the browser moves from page to page. When in the on state, recorded traffic is cleared each time you navigate to a new page. This is turned on by default.
Please note: Dev tools will close if the redirected domains navigate from a protected mode site to a non-protected mode site, e.g. from internet zone to intranet zone

How to make Google Chrome JavaScript console persistent?

Since I'm building a dynamic site, I need to track the changes between pages, ie. Ajax calls, POST, GET stuff and similar stuff.
I'm looking for the same functionality like in Firebug (where you can enable "persistent" and the console is not cleared every time you reload a page or submit a form.
So, my questions is: is there a way to make Google Chrome JavaScript console persistent?
(And if yes, how?)
Update: Copying the answer here, if anyone's still looking for this, Chrome 14+ has a setting in Developer Tools > Settings labelled "Console: Preserve log on navigation".
Update 2: the latest versions of Chrome (33+) have this option by right-clicking in the console.
Update 3 (late 2017): The latest versions of Chrome (60+) have this option by opening the console, clicking the gear in the top right corner and selecting "preserve log"

If anyone's still looking for this, I'm on Chrome 15.0.874.58 beta-m and I have a checkbox in Developer Tools > Settings labelled "Console: Preserve log on navigation". Does the job nicely.

at Version 67.0.3396.87 (Official Build) (64-bit)

Unfortunately, Chrome doesn't support that functionality yet, although there was talk in December 2010 about adding in the next major release...
This answer is no longer valid

As of Chrome Version 73.0.3683.86 (Official Build) (64-bit):
Click the ellipsis in top right of Developer Tools
Navigate to Settings > Preferences > Console
Check Preserve log upon navigation

Try this to enable console on popups

I had the "preserve logs" options enabled and still had the Console losing focus to the Sources tab. If that happens (apparently during debugging), it helps to disable "Focus sources panel when triggering a breakpoint" in "Settings > Preferences > Sources".

In Chrome v102
I opened Chrome Dev Tools,
I clicked on "gear" icon (Top right corner)
Enable "Preserve log" checkbox
