Description from store The Mobile/Responsive Web Design Tester extension allows Web Designers and Developers to test their web pages against common mobile, phablet and tablet devices by emulating the user agent and screen resolution. Excellent for testing responsive web designs. Easily switch between portrait and landscape mode and test multiple mobile device's at the same time! Very helpful when your site is in development and testing on actual devices can be difficult. Although using feature detection is best practice, there are still situations that come up in which you need to detect a devices user agent. The Mobile/Responsive Web Design Tester is unique in that it not only emulates device resolution, but also the device's user agent. ** Version 2.3 (9/2/2020) - Complete device list revised - Clear old/eol devices - Delete donation button ** Version 2.1 (7/30/2015) - Added a couple new devices ** Version 2.0 (4/5/2015) ** - Added option for enabling/disabling swipe imitation - Added support for mouse wheel scrolling while in swipe imitation mode - Added portrait and landscape buttons to make switching between the two modes easier ** Version 1.9 (11/20/2014) ** - Added back button ** Version 1.8 (11/19/2014) ** - Bug fix in scrolling ** Version 1.7 (11/18/2014) ** - Implemented better scrolling ** Version 1.5 (11/16/2014) ** - Updated/added new devices - Updated layout - Added donate button - Didn't change anything, but mouse scroll worked in this round of development. Hopefully it works for everyone in production. We'll see. - Corrected bug that occurred on https pages.

  • (2020-04-13, v:2.2) Meenu Nachiappan: Version of devices
    Hi, We have support for all different devices, which is good. Can you please let me know, where I can find the information about different devices? for ex: we have Nexus model but I would like to what screen size it is rendering, what is the underlying OS? etc... Rgds, Meenu
  • (2019-06-19, v:2.2) Kevin Fiddick: Mobile Viewer
    I'm looking around right now, and I don't see an easy way to remove the bottom text of the viewer. The bottom bar, that says the device name and offers a back button, overlaps with my page and gets in the way frequently. Love the Plugin, I use it everyday
  • (2019-05-14, v:2.2) Vladimir Dugat: Monetization of browser extensions
    Hello, We are looking for partners with extensions who are interested in installing our SDK extension for Chrome / Opera / Yandex. Our SDK collects anonymously advertisements displayed to users. Are you interested in the discussion? This can be an additional income for you. We do not compete with any other monetization, such as search or advertising, we exclusively collect advertising data displayed to users. All this is compatible and transparent, does not affect the UX speed, surfing speed and user usability. Thanks! -- Kind regards, Vladimir grow.rdd @ gmail.com
  • (2019-02-23, v:2.2) Mark Evans: Permissions
    Great idea for an extension! Can you revise the extension to use less-invasive permissions? "Read and change all your data on the websites you visit" is 100 out of 100 on the risk scale.
  • (2019-01-16, v:2.2) Ramas Grikštas: Chrome on imac pro
    Good stuff, but bad working with imac, with imac open full screen window when you click on all devices. Please fix it.
  • (2019-01-03, v:2.2) Steven Chrisman: Add more phone options
    There are iPhone 7, 8 and X out now. Can you add them to the list of phones to test?
  • (2019-01-01, v:2.2) Please add option to remove unwanted phone types
    Hello, great app but could you please add an option in the settings that allows us to remove some of the resolutions that we do not want? Also the option to save our custom dimensions would be great. I am using this app more because I notice the web view of a certain website looks cluttered but on my phone it looks organized so this extension allows me to view the page in a different resolution which is cleaner. Thanks.
