I use the Google Chrome remote debugging protocol to get benchmarking information of the page loading process with Google Chrome. I would like to switch to Opera which should offer the same functionality now that it runs on Chromium.
I started Opera with the cli parameters "--remote-debugging-port=9222 --enable-benchmarking --enable-net-benchmarking" similar to starting Google Chrome. I discovered that benchmarking seams not to be started in Opera - the chrome.benchmarking object is not visible to JavaScript.
I didn't find any documentation on the cli parameters for Opera, neither how to work with the remote debugging protocol in Opera.
Does anybody know how benchmarking can be enabled and/or the remote debugging protocol works in Opera?
Maybe you don't need this anymore, but I did today.
For some reason (maybe it's by design, but I didn't bother to check), you can't really start two separate instances of Chropera. Therefore, you first have to exit opera (from the menu to save your session).
Then, find your installation directory, and start Opera with the params:
C:\PROGRA~2\OperaNew\31.0.1889.174>opera --remote-debugging-port=9222 "http://www.opera.com"
(Maybe you can use launcher.exe, but I didn't bother checking)
Then, using another browser, visit http://localhost:9222. Maybe you can use the same one, but again, I didn't bother checking.
Now it's just the same as the Chrom(e|ium) protocol.
Hope that helps somebody.

According to PhpStorm documentation:
Debugging of Vue.js applications is only supported in Google Chrome and in other Chromium-based browsers.
People like Jonathan Bossenger already tried to circumvent this dependency and make it work with Firefox anyway, but only to come with conclusion like:
Even if you try to edit the available list of browsers and enable Firefox it won’t come up as an option. Believe me, I tried!
Which lead to the question: what is integrated within Chrome/Chromium which is not present in Firefox, leading to this deficiency in development facility?
We used to support Firefox remote debugging (but without source maps) through the FireFox Remote run configuration, but our solution doesn't work in the latest Firefox versions due to changes in the protocol, and there doesn't seem to be an easy way to fix it. We've made some progress recently, but there are still some blocking issues.

OK, so I've gotten acquainted with Neptune notebooks (a fork of Pluto notebooks) and they work fine on my machine, even on the FF browser (my default browser right now).
However, as the printing capabilities of these notebooks aren't quite there yet, I need to open a notebook on Chrome (or its open-source version, Chromium). When I try to do that, I get an authentication error (something about a "secret" that it needs, though it's quite vague as to what that is and where it would be inputted on the browser). I have full access privileges to all the folders involved, on my Linux Mint machine, running one of the latest versions of Julia.
Is there a way to do that, without having to make that my default browser?
Thanks
Just use the option launch_browser=false when starting Neptune.
julia> Neptune.run(;launch_browser=false)
Go to http://localhost:1234/?secret=xs5m1mnx in your browser to start writing ~ have fun!
Press Ctrl+C in this terminal to stop Neptune
Now copy the link that you see in console (http://localhost:1234/?secret=xs5m1mnx in my case) to Chromium and have fun!
I'm working on a monitoring tool for my website to log data. The actual logging is made on server. My goal is to calculate stats based on how long the user stays on the website.
Main question: I used chrome headless command --remote-debugging-port=80. I got logs for up to 10 minutes. Works perfectly. But how long will it work if left working? Is there a default timeout? If yes, how can I change it? If I want to run it exactly 30 minutes after page finished loading?
I'm trying to do the same on firefox (tried using PhantomJS but it wasn't loading the page correctly even though useragent was set to firefox) but firefox just throws an bank page when I'm trying to start a headless mode. I used "firefox -headless" and tried capturing an screenshot. It was just exiting my currently open firefox tabs without capturing any image. Any idea?
Using firefox quantum 59.0. I don't want to use selenium.
Also PhantomJS solution would be great. Currently I just want to collect logs. So, it only have to run all javascript (an jquery) code on the page which then sends the data using ajax. I tried page.onLoadFinished and then a wait function to make it stay on the page for the exact time after page loading.
Since no one answered, I will try to answer my own question after even more research and logical thinking.
Main question: Seems that there is no timeout but if need can be used --timeout X. Even though it's not perfect because it runs independently if the page if fully loaded or not.
As for the firefox, it's buggy. -new-instance (make headless run while you are already on firefox) is not working and -no-remote didn't help. Firefox is only working if running only one instance. So, if it's the PC you are working on and you want to run tests too, firefox is not for you. Headless runs only when no other instances of firefox are running, while chrome runs fine.
PhantomJS didn't work even though tried multiple solutions.
Best solution? Use chrome. Need portable? Use chromium and use headless. Or write your soft to use cefsharp which is based on chromium. Your browser with all libs will be around 120-200MB. Pretty big for portable but do it's work. Same as portable chrome or chromium. CefSharp have a privilege of integrating whatever you like into the browser since it's a... browser.
I currently have a Chrome extension that uses Chrome's APIs and plan on making a Microsoft Edge version once it opens up as well. My question is how do you work with the multiple API's?
For example, I use the following to check if the extension has just been installed or not:
chrome.runtime.onInstalled
I'm assuming for Edge it would be something like:
edge.runtime.onInstalled
What's the best way to work with both of these? Do I just duplicate the code within the file where there is a copy of the code for one and the other and presumably the browser will ignore the other browser's code? (doesn't sound like the good option)
Or is there some cross-browser framework that I should use instead?
Or is there some other solution?
And please forgive me, this is my first entry into building extensions/apps, I'm generally just a Web Designer.
Thank you!
All browsers support or
chrome.runtime.onInstalled
or
browser.runtime.onInstalled
So, the right way is to start scripts in your extension with this code:
var browser = browser || chrome
And then use browser, for example:
browser.runtime.onInstalled
(I'm sorry about my english)
Edit:
Chrome and Opera support chrome and not browser.
Firefox support chrome and browser.
Edge support browser and I don't know if it support chrome.
Anyway, my solution work in all browsers.
Update (5.8.16):
Edge support browser and not chrome.
I'm trying to run a different browser mode on IE with selenium using c#. Here's some code:
var ieWebDriver = new InternetExplorerDriver(#"PATHTOWEBDRIVER");
ieWebDriver.Keyboard.SendKeys(Keys.F12);
ieWebDriver.Keyboard.SendKeys(Keys.LeftAlt);
ieWebDriver.Keyboard.SendKeys("b");
ieWebDriver.Keyboard.SendKeys(Keys.NumberPad7);
I can open the developer tools (f12) but I'm not able to change the browser mode. Is IE preventing this due security? if so, are there any other ways to render content with a lower IE version?
thanks
No. The IEDriver is going to launch whatever IE is installed on the machine.
Changing the 'browser mode' is not a true representation of that version you are changing it to. IE9 on IE7 Standards Mode is not a true version of IE7.
Thus, you are stuck in a problem. You want to test different versions of IE, how do you do it?
The problem is that Windows let's you only have one IE version on a Windows PC at any one time. Yes, there are hacks and programs around to get multiple versions (IE5 and above) to run on a single machine, but they are hacks. Hacks which are not going to work all that well, and still, even with this, you wouldn't even be able to give the IEDriverServer the flexiblity to do this.
You will have to have seperate Windows machines.
A workaround, which again is a hack, is to set browser emulation mode in the registry, as documented in SO question.
Note that in the above question, the accepted answer is not going to work but the other answer may do. As note the comment on that answer, is by the maintainer of the IEDriver itself, advising strongly against this.
Another workaround, I have not tested, is perhaps use the native C# Keyboard.SendKeys, as documented here in MSDN. Am unsure if it will work (don't think anyone has ever ried it), but it is another option.
Selenium supports cross-browser testing of different versions of the same browser, but it is not achieved by switching the version in the Browser Mode in F12 Tools.
See https://code.google.com/p/selenium/wiki/Grid2
You can set up virtual machines with different versions of IE that work as Selenium nodes and use Selenium Hub to connect to them. Let's say you have a virtual machine with Windows 7 which has IE9 installed. You would start a Selenium node there and specify that it accepts requests for IE9 tests. You would then create InternetExplorerDriver for version 9, connect to the hub and run the test. The hub finds out the node with IE9 and runs the test there.

This is of course different to what you're trying to do on a single machine, but it's more reliable and prevents you from extra management of your local IE instance.
