Note: If you hit a Paywall, while trying to view a SF Chronicle article for example, it is still possible to read the material.  Firefox: Right-click on the link and choose Open Link in New Private Window.
Other browsers, do the following:
— copy the link: put the cursor over the link and right-click.  Choose Copy Link Location (or Copy Shortcut)
— open a New Private Window:  Choose File .. New Private Window (or type Ctrl+Shift+P)
— paste the link in the new Private Window, then hit Return.
When done reading articles close the Private Window.
