Meta Viewport Adder was created to solve a problem I had when using my favorite browser Firefox, my goal is not to dedicate myself to add features in the short or long term.

If you want to add any feature, improve the code, etc; you can feel free to do so.

Find it in:

• Firefox.
• Chrome.
• Edge.
• Opera.

If there is a native way to do it in Firefox (such as about:config), please notify me and I will remove it.
