I have used and loved this extension for quite some time but now it is no longer working properly. Instead of resizing the current window, it now opens a new window, which means I can no longer test my current window/website at different resolutions. Also, why does it now need permissions to read all data on sites??
This was great, used it for years until recently they changed it and now changing the resolution opens the tab in a new window. This is worthless now and other extensions do what it used to do better. Not sure why it was changed but it made a 5/5 extension into a 1/5.
Used to be great but now there is this screen shot feature that is annoying. Also, it's not persisting the custom resolutions I am adding...
very good extension , i use it everytime I want to dev an mobile first app
Great tool to check your responsive designs.
Nice extension, very helpful and realistic.
Why? Why is opening in a new window now? You ruined the extension
Great Mobile Simulator, very helpful for testing!
Great app...! Love it very easy to use
Love it! It helps me with learning so much better.
This is one of the best and most useful Chrome extensions I have used.
They really earned this 5-star I gave them... Well done guy!
Super useful extension that i use on daily basis!
Greate extentions!
I use this extension often to check on how my sites look after modifications!
This extension is very helpful and very authentic!
Good plugin.. can help me a lot!
Latest update reveals dev real intent... requests way too much permissions as of late. dont install!
From version 3.1 and later it changed to completely different extension which requires much more permissions than before, so it not "Resultion Test" anymore. I think it was sold to other party.
Why does it need "Read and change all your data on all websites" now?
Было нормально, каждое разрешение открывалось в этом же окне, теперь новые окна плодятся, которые надо закрывать. Не удобно стало!
Cannot save custom resolutions anymore for some reason. Worked ok a couple of weeks ago.
Solo tiene medidas en px, las cuales son muy relativas
Simple, effective tool -- works perfect for my use-case! Needed something EASY / FREE to use and this more than fit the bill! Kudos to the developer!
You cannot resized it to tablet and mobile screen views.
The size is wrong, I tried 1024x768, then I added event mousemove to see if the window.innerWidth / innerHeight is correct but no, it was wrong.
16px less when resized
Doesn't resize
如果点击没反应尝试开一下科学上网
used to be awsome,now don't have exact sizes any more....sad
可能是chrome更新的原因，不知道从哪个版本开始，点击插件按钮没反应了。重启chrome也不行。这么好的插件别不能用了啊
Funguje OK, jen teda nevím proč potřebuje přístup k Čtení vaší historie procházení
Doesn't actually resize anymore. (Yes, I restored the window first.)
Ok, but not perfect. A manual added resolution does not get triggered by the "View all selected"-button
not working
2 seconds or more to open the extension window
got 1280x710 instead of 1280x800 :(
很实用，很方便。只是反映速度有点慢
Не хватает возможности регулировать высоту выпадающего списка с разрешениями, у меня их много, приходится прокручивать. Can't change the height of the resolutions list, vertical scroll-bar appears.
经常点不出来，why？
Good plugin.. can help me a lot .
Added advertising, and waiting for the ads to load has slowed it down. There are better extentions that don't have ads.
Too slow!
Have been using it for years now... One of the bests.
Не работает. Не появляется панель выбора разрешения - жму на кнопку расширения в панели браузера и ничего не происходит.
Imprescindible para el desarrollo responsivo. Muy buena
Moze być :)
Очень быстро и просто. Пока все работает хорошо, спасибо!
Doesn't really work. It does resize the window, but not to the size specified. Choosing "1280 x 720" for instance results in a window with outer dimensions of 1272x716 and a viewport of 1268x609. Makes no sense whatsoever. Completely useless as-is.
Why my navigation history is needed to install it? I can't figure out how this information would be useful to resize my window.
