How can I debug something in IE9 - strange behaviour - html

I have reported bug, that something doesn't work in IE9. I started IE and I saw that bug, but as soon as I ran developer tools in IE, my bug was gone and everything works well. Unfortunately when I run IE again bug is still.
What is the worst it happens not only for one concrete bug. It happens all the time. So it isn't nature of bug, but IE. It prevents me to debug it. What can I do?
I didn't switch mode of engine in developer tool

My problem was that there is console.log(...) in my code.
Until I don't run developer tools, console doesn't exist and it throws error and my code stops, so rest doesn't work.

Chrome Version 102.0.5005.63 (Official Build) (64-bit) invalidate session after 30 seconds

We are seeing a really weird issue with our production site where after 30 seconds it appears that the session is invalidated in the Chrome and Edge browsers. We don't see any errors in the chrome inspect console.
We saw this behavior on 25MAY2022 right around when chrome 102 got pushed to the browsers at 5pm. IF we use inspect and turn off the cache then we don't see any issues with loading the site and everything operates fine.
FireFox works fine.
I'm using chrome 101.0.4951.61 against the same site on my android 11 phone and I cannot reproduce the issue.
Are there any new features in 102 we could turn off to see if a specific new security check might be at play?
My team is experiencing a similar issue when calling our API. If you go to chrome://flags/#private-network-access-send-preflights, and disable it, does that resolve your issue? If it does, then adding this header to your site may resolve the issue:
Access-Control-Request-Private-Network: true
We are currently doing pre-prod testing which is so far promising.

Processing sketches have stopped working in Chrome and Firefox

I just noticed this yesterday. My processing sketches on willhay.io have stopped working in Google Chrome and Firefox, however, they work fine in Safari. I haven't changed their code so it is very strange. Console is giving me this error
GET http://willhay.io/cdn-cgi/pe/bag2? r[]=http%3A%2F%2Fwillhay.io%2Fprocessing%2Fprocessing.min.js 405 (Not Allowed)
Something to do with Cloudflare maybe (I've just got the free version)? Check it out for yourself here:
http://willhay.io/processing/trip/
Turns out it was CloudFlare and the way their RocketLoader page speed optimizer works. I just turned it off after remembering I switched it on the other day and the Processing sketches are now working fine. Had something to do with the way it messes with the javascript and I guess processing.js didn't like that.

Site is not working in chrome, but works in FF and IE

Strange behavior.
This site: ****
Works in firefox and internet explorer, despite the insecure certificate.
But doesn't work at all in Chrome, and says ERR_CONNECTION_ABORTED
Anyone else getting this? I've tried it on 3 different computers already, and can't figure out why Chrome doesn't see it. Also, I can't get it to work on an iphone either.
How do I get this to work in all browsers, am I doing something wrong? Someone help
It is possible that Microsoft Update KB2992611 is causing the problem. See this article: http://www.infoworld.com/article/2848574/operating-systems/microsoft-botches-kb-2992611-schannel-patch-tls-alert-code-40-slow-sql-server-block-iis-sites.html
Uninstall the patch solved the problem, but I am not sure of the right steps to take to fix what the patch was intending to fix.
I can get to the site over HTTP, but not over HTTPS (tested in Chrome 38.0.2125.122 and Safari 8.0). Does this help?
I have similar problems begin lately with HTTPS pages of two websites on Win server 2012.
On most computers it works fine.
But in some computers:
In IE FF or Safari its OK,
But in Chrome or new Opera it raise error:
"This webpage is not available
The webpage at [my https url] might be temporarily down or it may have moved permanently to a new web address."
In Chrome it show also: "Error code: ERR_CONNECTION_ABORTED"
This failed requests not appear in the IIS logs.

KineticJS 4.6 no longer working in Chrome 29

I'm working on a project using KineticJS version 4.6 (currently the latest version), and since last night's Chrome update to Chrome 29, the Kinetic canvas is completely blank. While using the console, I am still able to detemine that the created objects, such as the Kinetic.Stage and Kinetic.Layer, still exist and are filled with correct data.
Afterwards, I tried loading the same page in Internet Explorer and Firefox, and they still work as intended, showing the canvas with the correct elements.
I have tried searching for people with similar issues, but I guess Chrome's update is too recent to show any results. Does anyone perhaps know if there is a way to fix it or if I should simply wait for either a KineticJS or a Chrome update?
EDIT: And now it suddenly works again after restarting Chrome. Hotfixed?
EDIT2: After a while it broke again, but restarting the browser seems to work
EDIT3: It is a bug in Chrome, acknowledged by the Chromium team in this thread. The thread states that the bug is definitely fixed in version 30, which is currently in beta. This fix may be merged in version 29 soon, but there is no definitive timetable for this.
We have the same problem in Chrome 29.
In some cases a workaround is to tell your users to use Chrome Incognito mode to fix this issue.
A test to replicate the issue consistently is posted here:
https://github.com/ericdrowell/KineticJS/issues/585
At present, the bug is not present in Chrome 30. (8/27/2013)
You should star this chromium issue:

Why is Dev Tools bar empty?

I'm using Chrome-compatible SRWare Iron 5.0.381 on XP, and was checking out what Chrome has to offer to developers, EG inspecting the contents of the DOM of a currently-loaded web page.
But when I hit CtrlShiftI, the bar is totally empty:
Does someone why this is? Do I need an add-on? Are there other Chrome-compatible tools I should know about?
It appears you’ve found a bug in that fork of Chromium. The inspector works just fine with Google.fr in the latest Google Chrome and Chromium builds. Why don’t you use one of these browsers.
Usually the reason of that is some problem in DevTools JS code.
It is a chance that problem will be solved by chrome restart.
Such kind of problems can happen when chrome is upgrading at background.
The other reason of that can be some changes which you made in DevTools.js.
Of cause if you have done some changes :)
You can troubleshoot such problem by another instance of DevTools.
As example you can try to load DevTools.html page into Safari, open WebInspector for it and check console messages.
