Such a Useful Extension for Frontend Development!! Easy & Minimalistic UI Loved it!! Love the User agent Switcher and Sync Scroll. Best Tool , Will recommend to my peers .
Add a toggle to hide and show toolbar
so much better than native chrome dev tools
A nifty little tool for frontend development. Quite like the snappy and minimalistic UI. Saves me from having to open multiple browser windows. Recommend.
It's a very helpful tool. I can view now in one window how my photos on the website will look on phones, tablets, and so on. With full-page screenshots that I love. The user interface is intuitive, making it easy to use even for those less familiar with tech. Highly recommended for its efficiency and simplicity.
it does not work.... i clicked on extension , show nothing! waste of time!
I love your extension however you seem to hae removed the close button which is not very nice
Working with web projects 10+ years I can say this tool makes testing so much faster! Literally in minutes I can check responsiveness and other parameters and feedback them to the tech team. Love it!
Speaking as a designer, this tool really helps me out with checking website responsiveness. It's so easy to use, and I don't have to mess around dragging browser windows anymore. Saves me a ton of time.
A handful extension from a QA perspective. It allows me to use different user agents quickly and go through different device views of web pages.
