Ok, you made me count. I have exactly 50(!) windows open, and the three first windows I checked had 34, 7, and 15 tabs. I know at least two of the windows have about 100 tabs each. Altogether, I estimate maybe 700-800 tabs?

I wish I were joking.

When I usually end up bookmarking all my open tabs after 3 months, they are often above 1000 tabs ... and this both at work and at home. Seems some of my coworkers suffer from the same ailment but with less pronounced symptoms.

Is it serious, Doctor?

By the way, in Firefox, if you end up pinning too much tabs you are left with very few space to manage your regular tabs ... and there is no scroll buttons for pinned tabs. I should maybe fill a bug one day.
