Chrome Developer Tools – Easy Web Debugging You Need to Know

Another extremely useful feature is Network latency modifier. You should always test every website on at least a 3G connection, and make sure users can see important parts of your site in reasonable time.

For advanced users, you should NEVER use the Network latency modifier in Chrome, and use something like Network Link Conditioner on Mac. This is because Chrome applies the modifier after all the packets have arrived normally at the client, so testing things like HTTP/2 resource prioritisation becomes a problem.

hey @dirkstrauss The leading image in the article is an unnecessarily huge 22 megabytes png image that can be resized and converted to jpeg without any noticeable loss of quality.

Good thing there was the developer tool to change the URL of those images showing off the actions. They were 22 pixels high making them impossible to understand.

Nothing new showed here. It's the same stuff which can done with firefox devtools for internet centuries. Just use Firefox because you don't want to have a Google bug watching you surfing ... don't you? ;)

I got another great tip for you if you are using Chrome Developer Tools: Click in the URL bar, type firefox.com enter and press the big Download Now button. You will feel less violated!

Wow great article. Didn't know we could do so much with Chrome Developer Tools.
