Firefox is a popular browser, the functionality of which can be extended with additional tools (plugins). To find and enable the plugin you want, you may need to go to the browser extension manager, which can be found in the program's functions.
Enabling an installed plugin
To manage already installed Mozilla Firefox plugins and extensions, you need to go to the Extension Manager. To do this, click on the browser launch icon to open the main program window. After that, click on the Firefox button located in the upper left corner of the screen. You will see a browser menu, with which you can change the application settings, as well as select the functions of some extensions installed earlier. Click on "Add-ons". A tab will be displayed in front of you, on the page of which already existing plugins will be shown. Click on the "Enable" button to activate the required extension in the program window.
If the plugin is already activated, you can disable it in the same way. The "Disable" button will be located opposite the already enabled extension.
If you want to see a list of all the extensions available for inclusion in the browser, click on the "Plugins" item on the left side of the page. In the drop-down list in the name line of each element, you can select the launch parameters. To disable the use of the extension, select "Never enable". If you want to fully activate the module, click on the "Always enable" item. In some cases, you can also select Enable On Demand if you want to run the extension only on certain pages.
Loading new add-ons
If you want to download or activate a new extension for your browser, in the "Add-ons" section of the browser menu, select "Get add-ons", which is located on the left side of the plugin manager. You will be presented with a web interface that allows you to download any extension available for your program. With the help of the line "Search among add-ons" you can enter the name of any particular application. To find a suitable extension, you can also use the category list or the list of the currently most popular extensions.
Some plugins require a browser restart to complete the installation.
Having chosen the required plugin, familiarize yourself with its functionality. To install the plugin, click "Add to Firefox". Click on the "Allow" button to download the add-on. After the download is complete, wait for a window to appear warning you about the dangers of installing plugins from unknown authors.
