I want to add a guide for Opera, as it is also considered among the top, most used browsers in the world. 

For Opera users:

• Start the Opera browser.
• Click on the "Opera" tab menu located at the top left corner.
• From the menu, select "Extensions" and from the sub-menu, click on "Extensions manager".
• On the new window, select "All" and click the X button, on the top right corner of an extension to remove it.

Afterwards, reset Opera to complete the process.
