To do this, click on the icon with three horizontal bars in the upper right corner of the screen, then click on the Help button and, finally, on the About Firefox button. There you can check that you have the latest version or not, and, if so, update it.

Therefore, both do not touch, unlike others that you have installed manually or have been installed by an external program automatically. If this is the case, check and do the following:
- Open Firefox and click on the icon with three horizontal bars in the upper right corner of the browser.
- Then click on Plugins and themes.
- Then find the button Plugins and check if there are other plugins installed, apart from the two already mentioned. If there are, click on their respective three-point icons that appear in the upper right corner of their boxes and choose the option to Never activate.

Start Firefox in Safe Mode
When you start Firefox in Safe Mode, extensions, themes and custom settings are temporarily disabled until the browser is restarted.

For it, copy and paste the following into the address bar: "about: support", without the quotes, of course.
