How to Change Firefox Application Settings

Last Updated: September 6, 2019

Firefox is a web browser favored by a lot of people all over the world. If there is to be one thing that makes Firefox so popular, it is its wide range of settings that allow users to customize their web-browser experience down to the smallest details. Not content with that, Firefox constantly adds features, and settings and options are constantly improved. Among these little-known settings and options has to do with the applications running in the back of Firefox. You can easily adjust them to make your already-pleasant browsing experience even smoother.

Steps

1
Launch Firefox. To open the Firefox browser on your computer, click on that fox icon on your desktop, Start menu, or taskbar.
2
Click on the “Settings” button. Look for the icon with three short horizontal lines arranged on top of the other found at the top-right corner of the browser. Click on the icon to display a drop-down menu.

Click on the Applications tab under Options. To get there, click on “Options” from the drop-down menu. A window will pop up where you will see among the tabs one marked “Applications.” Click on it to display the options under it.
4
Look for the application with settings you want to change. A white box will appear in the Applications options menu with all of the different applications running on your browser. (At this point, it will be slightly different for each user.)
- To look for a certain application, click on the search bar at the top of the screen, type in the name of the app, and hit Enter. If Firefox finds it, the application will appear in the box.
5
Re-configure the settings on your applications. To the right of each application is a drop-down menu that you can click on to get information about what you are allowed to do with a particular application. Just tweak the settings according to your preferences.
- For instance, with the application Adobe Acrobat Forms Document, clicking on the drop-down menu beside it will display its own particular settings. One of the things you can do is to set “Always ask” on so that Firefox will ask you every single time how you want Adobe Acrobat forms to be opened.
- You can also just customize what opens the application without having to be asked by Firefox each time. If you look further down, you will see that the options on the drop-down list are “Use Firefox” and “Use Adobe.” Simply click on the one that you want to be your default.
6
Save your preferences. Once you've changed your application settings to make your browser experience smoother, click on “OK” at the bottom of the box to save your changes.

In order to download videos into mp4, you need to have a link of the video. Once you have a link (i.e. YouTube, Vimeo, Vevo, etc.) you can go to a converter site. Most allow for website downloads.
