Try resetting Google Chrome.
Google Chrome gives you the option to reset your browser settings in one easy click. In some cases, programs that you install can change your Chrome settings without your knowledge. You may see additional extensions and toolbars or a different search engine. Resetting your browser settings will reset the unwanted changes caused by installing other programs. However, your saved bookmarks and passwords will not be cleared or changed.
Reset your browser settings:
- Click the Chrome menu on the browser toolbar.
- Select Settings.
- Click Show advanced settings and find the "Reset browser settings” section.
- Click Reset browser settings.
- In the dialog that appears, click Reset.
Something could be attempting to install a popup or other adware. If resetting the browser doesn't solve the problem
then you need to look for some add-on/ app in your Facebook.
“Every atom in your body came from a star that exploded and the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics...you are all stardust.”― Lawrence M. Krauss
