In news that chills me to the core, Hazel, a software engineer, has been keeping around 7,500 tabs open on her web browser, Firefox, for the past couple of years.

The Firefox fan tells PCMag in a message that she keeps so many tabs open for nostalgia reasons. “I like to scroll back and see clusters of tabs from months ago—it’s like a trip down memory lane on whatever I was doing/learning about/thinking about,” she says.

There was a moment of panic where it seemed like she’d lost them all, but it’s OK, she figured out how to use Firefox’s cache to retrieve them all.
