Fixing python not found error for youtube-dl

1. Open up a terminal.
2. Type which python for python2.x and which python3 for python3.x to see which version of Python you're running.
3. Create a symbolic link between the installation path of Python and the local python directory by typing sudo ln -s /usr/bin/python3 /usr/local/bin/python.
4. Type youtube-dl to test it out.
5. Enjoy!

Rebuilding .bashrc for all open terminal tabs/windows

1. The following steps enable the system to check .bashrc's modification time and compare it to the modtime of the last sourced version of .bashrc.

2. Open a text editor or simply type gedit ~/.bashrc in a terminal. Note that the preceding tilde ~ and forward slash / denote the home directory, and can be omitted if your terminal is already in the home directory.

3. Append this to the end of the .bashrc file:

   bashrc_sourced=$(stat -c %Y ~/.bashrc)
   
   PROMPT_COMMAND='
       test $(stat -c %Y ~/.bashrc) -ne $bashrc_sourced && source ~/.bashrc
   '
   

4. Finally, type in . ~/.bashrc to source the file.

5. Cheers!

Tutorial for creating userChrome styles for Firefox

Since there is no real help or documentation how to style the new Firefox Beta 57 I found a way how to live-debug the userChrome.css file.

Create the userChrome.css

1. Enable userChrome.css support in Fx v69+
2. Open about:support
3. Click on "Profile Folder" -> "Open Folder"
4. Create a sub-folder named "chrome"
5. Change into the new folder
6. Create a file named "userChrome.css"
7. Add some rules
8. Restart Firefox

Live-Testing styles

Pre-setup

Before being able to try styles, you need to enable two developer options (only do this once). To do that:

1. Press Ctrl + Shift + I on Win/Linux or Cmd + Opt + I on Mac
2. Click on the cog that appears in a right or left top corner, next to other buttons.
3. Scroll down to Advanced Settings and check the settings "Enable browser chrome and add-on debugging toolboxes" and "Enable remote debugging".
4. Close the developer tools panel and proceed with next tutorial

Testing a style

1. Press Ctrl + Alt + Shift + I on Win/Linux or Cmd + Opt + Shift + I on Mac
2. A permission dialog will prompt you to allow remote debug, accept
3. Click on the tab Style Editor, choose file userChrome.css on the sidebar
4. Choose the style you want to preview from this repository, copy the code
5. Scroll down on the development tools window textbox, paste the code
6. You should see the style being applied. If you like what you see, you can click Save, otherwise it will disappear after restarting the browser.

Styling Context Menus / Popups

from /u/DanTheMan74 The Firefox dev tools, when they're opened for remote debugging of the browser content, have an extra option that's hidden behind the dropdown at the top right, a thing which many people have no clue about.

The toggle is called Disable Popup Auto-Hide and it does exactly what it says. By default Firefox (popup) menus disappear when you use the element picker, but you can make them stay around by activating this setting. This makes finding elements and their ids or classes much simpler.
