I'm the first to admit that I'm not a typical user of web sites. If I visit a site, I'm just as likely to be checking its source code or response times as actually looking at the content. I do web stuff for a living, and I'm also very interested in how sites work. Or why they often don't.
If you're like me, then I've got some news that might excite you.
Firefox makes a special version of its browser for people like us. It's called Firefox Developer Edition, and it's basically standard Firefox but with lots of added tools for examining and troubleshooting web sites. For example, the screen shot below shows its split screen that contains not just the page you're looking at, but details of each element on the page and how long it took to load.
You can download Firefox Developer Edition from https://www.mozilla.org/en-US/firefox/developer/ and it's completely free. It's a 0.5 MB download, which is malware-free according to VirusTotal and Web of Trust, though be aware that this is only a stub and it will download additional components when you run it.
