Developer tools for designers - Designing in the Browser

I want see theme in dev tools :)

I have problem I wish if you can help me I deleted accidentally my bookmark folder on Samsung galaxy S8 when I want to restore it I restart sync and sign in but I found all my bookmarks and history browsing were delete too so how can I restore them back

wow, very helpful.
I like accessibility and animations dev tools. Also VisBug tool is super cool as well.

Awesome, but as other asked. After designing in the browser, what’s the “best” workflow someone could suggest to iterate these edits and bring them to live development? Thanks!

I clicked for the dog.

Really good

I use Lighthouse quite a bit. I'm also using Timelines on Safari which also has the CPU usage... I think Chrome Canary now has something Performance Monitor which is quite nice to monitor JS. In firefox i use noscript to turn off specific scripts for testing. It would be nice if Chrome had something like that as well.

So VisBug is a Chrome Extension.. This tool is fantastic! Will help me out alot. Thanks.

I love dev tools! a tab i use a surprising amount is the coverage tab, just to make sure that my CSS is being used on the site and that i'm not closing in on the 50kb CSS limit in AMP, dev tools is an invaluable help for that!

Nice. The Animations dev tab is new to me!

By "left click" on an element, I think you mean "right click".. :) Left clicking elements won't (luckily) open up a context menu.

After I changing code in browser, how I can save the new changes to the existing file ?
