Debugging websites in Internet Explorer

Question

I have a Website that is really slow and “feels” really bad when used. The server is OK, this is a problem with clients, I assume that there is too much JavaScript or image requests, but since this is not my own site, I wonder if there is a way to show and profile the page from IE.

In Firefox, I used Firebug, Y! Slow and web developers extension to view all JavaScript, CSS, images and other requests, AJAX requests, etc., but in IE I did not see any problems. I know that I can use Firefox, but the page works better in FF than in IE, so I wonder if there is any development addon specifically in IE.

Edit: Thanks for the many suggestions! There are too many good answers to choose as “accepted,” but I will look at the various tools that are suggested.

Answer 1

There is an Internet Explorer web developer toolbar . This is not as good as Firebug IMHO, but it works.

IE8 will also come with one built-in.

Answer 2

Violinist with the help you see Internet activity. It shows the log of all request / response messages through the network stack.

Answer 3

There is a lite version of Firebug that will work with IE and other browsers, have you tried this?

Answer 4

Try Fiddler ! This is a free proxy server for debugging HTTP, which, among other things, gives an idea of ​​what is loading on your site, which can slow down, etc. It has advanced features such as decoding compressed resources, providing pre-configured responses for specific URLs, etc. Learning Fiddler is a must for any web developer.

Answer 5

I would also suggest two JavaScript memory leak detection tools:

• sIEve
• Microsoft JavaScript memory leak detector

Answer 6

Recently, I have been using a web development assistant . These are HTTP protocols better than Firebug. Allows you to run arbitrary Javascript.

Answer 7

There is a JS library called firebug light, you need to include it on your website. What it does for you, this allows you to pop up a div in which you can spit out text, for example in firebug, with the same statements that you make in firebug. MochiKit also has something similar.

Answer 8

It's not a profiler or plugin, but you may find that Quirksmode can help you rip off some of IE — when you find them.

Answer 9

Did you run client-side performance monitors to see what happens, for example. is there a lot of memory that slows down or is it all related to network traffic?

Another thought is if there are any logs that can be useful when looking at query times, if there are a bunch of files to download, and also Javascript to initialize things.

Answer 10

Using a network sniffer such as Wireshark or a proxy server, you can monitor traffic and see if the image and / or scripts are slowing down your site. If you are not sure, turn over or comment out your javascripts to exclude that their processing is slowed down.

If you don’t see any indications in the slow traffic network traffic - then you will have to do a deeper analysis of the javascript code itself - perhaps by inserting timers or other measurements to see which parts of this can be optimized.

Answer 11

I am using HTTPWatch . It provides all the information similar to Firefox LiveHeaders, but much more useful. It is also a great tool to determine if you have content that blocks operations to load additional content for the page.

Answer 12

you can try the debugging panel and companionJS from the same company http://www.debugbar.com/ and they are free and quite similar to Firebug in concept, but not so developed

Answer 13

HttpWatch is also quite surprising as IE plugins go.
