Hi, please see [[Firefox Reader View for clutter-free web pages]] If it isn't there, type '''about:config''' into the address bar, press Enter, accept the warning, scroll down to '''reader.parse-on-load.enabled''' and make sure 'Value' is set to True. If it's set to False, double click on it to change from False to True, then restart Firefox. ''If your question is resolved by this or another answer, please take a minute to let us know. Thank you!''
