In Chrome, a user can open up the DevTools Debugger and easily select an event listener breakpoint on the right in the "Sources" Pane.
I have been unable to find these features in the Firefox Developer Edition debugger. Curiously, when visting the Firefox Developer Edition website, they have a video that shows a user easily opening up the inspector, switching to the debugger, and clicking a panel on the right to bring up all these event breakpoints. In the version of Firefox Developer Edition that I am using (54.0a2), however, these buttons do not exist.
I have literally clicked every button on the debugger panel and am left scratching my head.
It seems almost unbelievable these features do not exist or were removed in a "developer edition" browser. Hoping someone can point me in the right direction.
Setting breakpoints on event listeners is obviously not yet implemented in the new debugger UI, but there's already a request to add it.
Note that you can simply switch back to the old debugger frontend by unchecking the Enable new debugger frontend option in the settings (only available in Firefox Nightly):
or by going to about:config and setting the preference devtools.debugger.new-debugger-frontend to false.

I am using Report Viewer to remotely generate reports and I wish to have the print control button in the report header using IE 11.
This question is similar to the following:
Print button not available in ReportViewer using IE11
I have not been able to solve this issue. I have upgraded Report Viewer 2012 Runtime to 11.1.3452.0 and SQL Server 2008 R2 to SP2.
I am using Windows Server 2008 R2 and .NET framework 4.5.1 on the server. IIS is version 7.
I can see print buttons in all previous versions of IE (10,9,8,....)
I've also tried forcing the user agent to IE10 using this line:
meta http-equiv="X-UA-Compatible" content="IE=10"
According to the answers to the above question, I should have the print button. Any other suggestions besides compatibility mode or creating my own print button?
ReportViewer client printing feature relies on ActiveX which is not
supported by any browser except IE 9 (or earlier), that's why you do
not get print button when Chrome, Firefox or IE10/11 browser is
involved. For printing, you should export to PDF and let the user to
print it.

IE needs an add-on, RSClient, for the print button to work. Normally, the first time a user loads a report on IE, you'll see a prompt to download and install the add-on. Unfortunately, a lot of things can interfere with this. I'm not sure this will help you, but security settings were an issue for us.
Try this:
Remove the RSClientPrint add-on if it's installed. (Open the Control Panel, Internet Properties. Click the Programs tab and Manage Add-Ons.)
Click the Security tab, select the Trusted Sites zone, and then click the Sites button.
Add your web site to the zone and save your changes.
Open IE and navigate to your web site and the report. Hopefully, you'll see the prompt to download and install RSClientPrint and everything will work well. If it doesn't try to download, I would focus on the server.
I created a new VS 2013 project and viewed the default.aspx page with the Firefox browser. When I check the net calls it has made, I see it making constant calls to:

Why is it doing that?
How do I stop those calls?
I see an infinite number of calls made to the above URL every 6 seconds.
Please help me understand this and fix this.
This is working as intended. Artery aka BrowserLink is a real-time connection from Visual Studio to all browsers running your code. It essentially allows Visual Studio to interact with every browser.
For instance if you have IE, Opera, Chrome and Firefox all running your code and you're trying to ensure cross browser correctness; instead of going to each browser and hitting f5 to refresh you can just click the browser link refresh button which will auto-refresh all of the pages for you.
Not everyone wants or needs to have this functionality so if you do want to disable it, as Gustavo Armenta said you can disable it by following the steps here: How can I disable __vwd/js/artery in VS.NET 2013?
I would recommend you to read this post first Browser Link feature in Visual Studio Preview 2013 to understand about this new feature that comes in with VS 2013.
And then to disable this, simply uncheck the "Enable browser link" option.
You can hide the polling requests from the Chrome developer tools Network tab so that the requests you are actually interested in become visible. You can hide the polling requests by adding a negative filter:
On the Network tab, click the filter button to open the filter options
Enter "-poll" without the quotes to hide the polling requests.
Example:
Had issues with that on site running with KnockoutJS framework. Pages were freezing for 10 seconds until "BrowserLink" external scripts were loading (using Chrome browser).

In my project(classified site) there are many aspx pages. in that i have post page where user can post the ads.. This page is not loading fully.. only half of the page loads and then it stops. This happens only in Internet Explorer(I am using version 8.0)
Browser returns follwing errors:
Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917)
Message: Object doesn't support this property or method
prototype.js
Please help me in this.
Have you checked your JavaScript or maybe JQuery codes?
Try to call that codes when the page is loaded.
Another solution is this:
Reset your internet explorer settings and run it. You can do this by following the steps given below.
If the problem is caused by damaged or incompatible Internet Explorer settings or add-ons, you can usually resolve the problem by resetting Internet Explorer settings.
To use the Reset Internet Explorer Settings feature from Control Panel, follow these steps:
Exit all programs, including Internet Explorer (if it is running).
If you use Windows XP, click Start, and then click Run. Type the following command in the Open box, and then press ENTER:
inetcpl.cpl
If you use Windows Vista, click Start Collapse this imageExpand this image . Type the following command in the Start Search box, and then press ENTER:
inetcpl.cpl
The Internet Options dialog box appears.
Click the Advanced tab.
Under Reset Internet Explorer settings, click Reset. Then click Reset again.
When Internet Explorer finishes resetting the settings, click Close in the Reset Internet Explorer Settings dialog box.
Start Internet Explorer again.
I ran into a similiar problem and this didnt help but I did find that the client had used the Ctl+Scroll and had Zoomed out to far causing the menu at the top of the page to start stacking.
Hope this helps though this post is older.

I am using the Web Inspector in desktop Safari (Version 6.0.2 (7536.26.17)) (under the Develop menu) to debug Mobile Safari's interaction with a web application in the iOS Simulator (Version 6.0 (358.4)).
At the moment, I would like to simply monitor HTTP requests; I am not interested in stepping through the javascript code. However, the Web Inspector keeps dropping into the debugger, even though no break points are set. I have to repeatedly click the "continue" button to get the entire page to load.
How can I tell the Web Inspector not to debug javascript?
The setting is there, I just overlooked it. In the Web Inspector in the pane on the left side, at the top, there are a bunch of icons. The second one from the right is a "breakpoint" icon. Click that. There are two entries at the top, "All Exceptions" and "All Uncaught Exceptions." I had "All Exceptions" enabled. Disabling that solved the problem.
Well since i installed IE 8 i get this error so i cant debug my asp.net page :(
"Unable to start program http://localhost:123/myapp/"
Could not find the element(or some thing like that translated from swe)
What must i do to get rid of this error? and IE more or less hangs after this, the window does respond but it only loads half of it components...
Edit: Is there any way to set what browser to use when debugging befor i installed IE8 i normaly used opera and it worked like i wanted it to...
i think you IE 8 is not properly installed try setting other browser as default browser.
if you don't get this error then it means you have to re install ie 8 again
Hi all these type of user i had resolved this error so u also must try it as follow below steps:
This is one of the various errors that appear when you are debugging and may haunt you until you do the following fix:-
In the Internet Explorer, "Tools" Menu, select "Internet Options".
Switch to "Security" Tab.
Click on "Internet" (The Globe Icon. Its actually the default selected).
Click on "Custom Level" in the bottom.
Scroll down to find the "User Authentication" section.
Select "Automatic logon with current username and password".
OR Anonymous logon.
Click "Ok" twice to exit.
Restart IE. (You don't need to reinstall your browser.)
