Cannot open Network tab in firefox developer tools - firefox-developer-tools

If I go to the firefox developer tools options and check the network tab it does not shows up. The others tabs works well.

SASS bug with compilation

I'm new in StackOverflow and I'm a beginner in web development thank advance for your comprehension.
I have problem with SASS
it tells me well in my terminal that it compiles my code on my main.css but this shows me the result only a few times on my browser (Firefox and I cleaned his caches).
I use the terminal of VSCode (Windows Powershell) I have SASS with node.js and local server with WAMP.
I find it hard to understand my other projects I did not have this problem.
Know what I can do to fix this?
You can find my code on GitHub and a video to show you the problem.
Thank you and have a good day!

PS: Sorry for my poor English.
First of all, check if the value actually changes within the compiled css file. Since your Sass compiler tells you that it compiled everything successfully, it should then be changed within your css file.
It is most likely your browser's cache. Clearing it once has no effect on later reloads as seen in your video. You can set your browser (both Firefox and Chrome) to deactivate Cache while developer tools are open.
Chrome: open DevTools [Ctrl Shift i], open its settings (either hit [F1] or open via DevTools menu), under "Network" check the box at "Disable cache (while DevTools is open)
Firefox: open Web Developer toolbox [Ctrl Shift i], open its settings (same with Chrome), under "Advanced Settings" check the box at "Disable HTTP Cache (when toolbox is open)"
Whenever you load a site with those tools open (as it should be when doing stuff like this) you will never run into cache issues anymore.

Keyboard shortcut to switch focus from web developer tools in Atom

Is there a keyboard shortcut to allow you to switch between Chrome Developer Tools and the main window and back again? I am looking for a shortcut that will work on Windows, MacOSX and Linux.
I don't think there is a direct answer to this. Unfortunately, all of the keyboard shortcuts for changing the focus are intercepted by Chrome Developer Tools. You can toggle the visibility of Chrome Developer Tools with:
Windows: Ctrl-Alt-i
OSX: Alt-Cmd-i
Linux: Ctrl-Shift-i
However once you are in Chrome Developer Tools very few Atom Shortcuts still work, this is maybe something that can be implemented in a package or in init.coffee.

Launching Internet Explorer 9 with Developer Tools

I have a script that runs in a browser add-on. It's using the log function of the console object that is only available when the F12 Developer Tools is loaded.
While I can disable the add-on and enable it again to see the early messages intended to be logged, I find it a bit annoying. Is there a way to load IE9 with developer tools? I'm hoping there might be an obscure argument to be passed to the application to enable that.
If this were possible, I would assume it would be mapped to a command-line options, however there doesn't appear to be any such option (though it would be a nice addition to the browser). A current list of all command line options can be found online at Windows Internet Explorer Command-Line Options.
With IE10, if you leave the Developer tool pinned to the browser window, it will be loaded the next time you open Internet Explorer after you exit.
Note that this will not work if it is unpinned.

Web browsers into kiosk mode

I have currently found a way to place the currently installation of Internet Explorer into kiosk mode using asp.net and VB
System.Diagnostics.Process.Start("iexplore", "-k " & "http://www.google.co.uk")
the "-k" parameter is the command that puts the browser into kiosk mode, however, other browsers such as chrome will only put the new instance of the page into another tab and firefox just opens the browser without loading the window.
I need to know what commands to pass so that chrome and firefox will respond in the same way as IE.
Many thanks
Chrome browser can do KIOSK mode with this command.
chrome.exe --chrome-frame -kiosk "your web page".
The good thing with Chrome is that you can build apps that can use the webkit animation and they look great for a KIOSK type applications.
It sounds like you might be interested in Windows Steady State, it's discontinued and doesn't run on win 7, but if you have XP or vista, it will let you lock down the PC nice and tight. This way you can restrict the use of programs to browsers you want (if you can't lock down chrome and ff) and on a reboot, it will clear any changes to the PC, basically returning you to a clean state status

Visual Studio 2008 SP1 - How to stop debugging in other browsers than IE?

Visual Studio has integrated debugging in IE, when you close IE, it stops debugging, and if you stop debugging, VS closes IE.
I want it to do the same thing with firefox/chrome! (mainly this 2, if is it possible with others, it'll be appreciated!)
Is there a way to do this?
Thanks in advance!
You need to change Visual Studio's default browser to Firefox/Chrome. To change this setting, right-click on an aspx file in Solution Explorer and select Browse With. Select the desired browser and set it as default.
What you need is to write a macro that opens up ff (or any other browser) with the debugging url.
Then you can control it and close it when the debugging ends.
but i think this task is quite hard to implement.
who mentioned here to simply set the default debug browser is not answering your question at all, b/c it will not be closed...
With Firefox established as your default browser and Firebug installed, you can debug your script in Firefox. Select Tools > Firebug > Open Firebug. The Firefox instance now shows the debugging console. To enable script debugging, click the Console tab, check the Script option, and click the "Apply settings for localhost" option.
