We have device emulations in chrome ( developer tools > show drawer > Emulation ).
Where can I find the same in Firefox browser.
It would make sense for a browser vendor to have a device emulator if they actually sell a device of their own that moreover uses their rendering engine.
Since there is such a think as Firefox OS I think this is as close as you will get:
Firefox OS 1.1 Simulator Add-on
A dedicated page for the OS Emulator:
Firefox OS Emulator

Are we able to test angular 8 application on safari browser 5.1.7 on windows OS or any polyfills to be added or any tools exists?
There's no reason to be testing on Safari for Windows. It was discontinued in 2010 and is no longer supported by Apple.
According to NetMarketShare, Safari for Windows has a 0.01% market share, less than QQ, Sogou, Opera, Yandex, UC, Maxthon, Baidu, Vivaldi, and Amigo. Unless you're also testing all of those, don't bother with Safari for Windows.
Safari for OSX or iOS is a different question, but to test those browsers, you'll need a device that is actually running OSX or iOS.
I have ZTE Open with Firefox OS.
I have macosx laptop. (And also parallels with windows vista, 7, 8 etc. if it may help…)
I enable remote debuging and console in phone settings and remote debuging in Firefox Nightly on desktop.
Download adt-bundle-mac-x86_64-20130917 from http://developer.android.com/sdk/index.html
and run:
./adb devices
List of devices attached
roamer2 device
So device is connected
Then I run
./adb forward tcp:6000 localfilesystem:/data/local/debugger-socket
Because this article https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugging
Then I open Firefox and
Tools -> Web Developer -> Connect…
And nothing… Just timeout. Then I try
./adb forward tcp:6000 tcp:6000
Get this on my ZTE Open:
Click "Ok" and get this on my desktop:
No tabs!
What I am doing wrong?!
Help me please.
Remote debugging requires Firefox OS 1.2 or greater, which I do not think has been released for the ZTE Open.
More information regarding remote debugging with App Manager (simulator):
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Using_the_App_Manager#Firefox_1.2.2B_required
And here's some info on the ZTE Open:
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Developer_phone_guide/ZTE_OPEN
The instructions from #christi3k work for remote debugging an app within Firefox OS on my ZTE Open C.
When I want to debug a classic webpage, it's not working at all within Firefox OS context.
It will only work in an Android context according to https://bugzilla.mozilla.org/show_bug.cgi?id=1009518 but maybe I miss something.
I wish to implement the suggestion in this post:
Visual Studio 2012 Mobile Device Emulators
but Opera Mobile Emulator seems to no longer come in a Windows version. Anyone else experiencing this issue?
Yes, that's not just you.
People at Opera forums discovered a direct link to the Windows version:
http://www.opera.com/download/get.pl?sub=++++&id=35131
Considering that the link in the article on this topic has no mention of the Opera Mobile Emulator, I concluded that the desktop version is no longer supported. However, all major browsers have a built-in mobile emulator in the developer tools.
For Opera, these are the steps to access it:
Select the tab with the web page to be tested
Open Menu > Developer > Developer Tools or CTRL + SHIFT + I
Select the "Toggle device toolbar" icon at the top left (looks like a phone next to a tablet)
Select the device from the first drop-down menu on the toolbar. It will be "Responsive" by default, or the last device used.
It's a similar process on other major browsers, like Chrome, Firefox and Edge. Comparing to physical devices I'd say it's reasonably accurate for testing layouts. It doesn't have the latest phones like iPhone 12 at this time, but you can add a custom device by specifying the viewport height and width.
My understanding is that each browser tests how it would behave on its own mobile version, which means, it's best to test it on the developer tools on all supported browsers. On this topic, there are tips and links to commercial testing tools on the MDN article on cross browser testing. My main take away is test a lot, and fix or provide fallback solutions.
Are there any add-ons to test an HTML page to see what it will look like on a mobile device? I'm developing with PhoneGap but Eclipse emulator is too slow to refresh it all the time so I want to have a browser extension that make screen resolution like on mobile.
If you care only about the screen size, Firefox 15 (currently Beta, release coming up in two weeks) has Responsive Design View in the Web Developer menu that allows you to adjust "screen size". For example, you can select 360x640 (nHD resolution) and have a look at your page.
However, mobile browsers do custom adjustments to web pages and these adjustments depend on the browser used. For example, Firefox Mobile does something called Font Inflation. You cannot reproduce it in a desktop browser, you have to actually run Firefox Mobile for that. The problem: mobile browsers will only run on mobiles, even Mozilla stopped supplying Firefox Mobile for the desktop after they switched to the native Android UI.
Edit: Starting with Firefox 33, there is a Firefox OS simulator built into Firefox (thanks to Tomek for pointing me into this direction). To start it, open WebIDE, then click "Select Runtime" and choose "Firefox OS 1.3." This will start the simulator, all you need to do then is clicking the Firefox icon (for me it's a blue one, not the usual orange). There you are, you can test any website in a real mobile browser, right on your desktop.
Firefox OS simulator can do the trick: Just install it. Run it - and run the browser inside. :)
I don't know if this is the correct site, but do you know if there is a good emulator for mobile firefox out there? I want to make some tests on mobile firefox and I don't have a smartphone available :S
Mozilla provides windows, linux and mac os versions of Firefox mobile: https://www.mozilla.com/en/mobile/download/
You can use Firefox OS Simulator, too. It's a browser add-on. https://addons.mozilla.org/en-US/firefox/addon/firefox-os-simulator/
Take note: When you install this add-on and encountered a pop-up related to the add-on, just press "Continue" and NOT.. I repeat NOT "Stop Script" :)
