The way your web content behaves on mobile can be dramatically different from the desktop experience. Remote debugging with Chrome DevTools lets you debug live content on your Android device from your development machine.
There are two ways - the first way is just one command run plainly in front of you; the second one runs in the background and in a different instance so you can get out of your ssh session and it will continue.
First make a folder to download the websites to and begin your downloading: (note if downloading www.SOME_WEBSITE.com, you will get a folder like this: /websitedl/www.SOME_WEBSITE.com/)
| # One liner | |
| wget --recursive --page-requisites --adjust-extension --span-hosts --convert-links --restrict-file-names=windows --domains yoursite.com --no-parent yoursite.com | |
| # Explained | |
| wget \ | |
| --recursive \ # Download the whole site. | |
| --page-requisites \ # Get all assets/elements (CSS/JS/images). | |
| --adjust-extension \ # Save files with .html on the end. | |
| --span-hosts \ # Include necessary assets from offsite as well. | |
| --convert-links \ # Update links to still work in the static version. |
chrome/userContent.css under your Firefox profile folder
| function mySlowFunction(baseNumber) { | |
| console.time('mySlowFunction'); | |
| let result = 0; | |
| for (var i = Math.pow(baseNumber, 7); i >= 0; i--) { | |
| result += Math.atan(i) * Math.tan(i); | |
| }; | |
| console.timeEnd('mySlowFunction'); | |
| } | |
| mySlowFunction(8); // higher number => more iterations => slower |
This can reduce files to ~15% of their size (2.3M to 345K, in one case) with no obvious degradation of quality.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000
