Damn you Firefox! This is the third time...

5. Firefox

Ubuntu/Mate 16.04
I have a hold in circuit using a small relay so if we lose power and then get a power surge my electronic components are protected because they're not connected since the power lose dropped the relay out and opened the contacts that I use to power my components. In other words around here it happens quite frequently that we have a blip in our power so the relay drops out, power goes off of my computer and it dies. Once I decide that everything is ok and push the on button again which picks up the relay closing the contacts and restart my computer then I click on Firefox all my open tabs are right there just like they were when the power goes off.

So it must be a problem with your operating system or how you have it set up. Is my guess.
