I've got a decent number of Raspberry Pi 3 Model B & B+ boxes set up in my call center office for basic web browsing. They run Raspbian Lite Stretch with only Chromium installed (and Openbox to actually allow this to run). The idea was to provide budget friendly computers for the one task my team needs a computer for, which is using the internet for things such as Gmail and basic web browsing.
Long story short, I'm looking for a way to limit the Tabs they have open in Chromium, as this seems to be the best suited browser for these modern uses.. Ideally they would only be able to have 2 open at a time Max. I couldn't find much useful info with some google searching so I was hoping someone here has an idea.
P.s. I'm not opposed to a browser for this platform that can handle your basic day-to-day websites, such as Google, google maps, gmail, etc, if that's what it's gonna take. I've experimented with the other go-to options but have still ran into this issue.
Again, these computers are only running Openbox over Raspbian lite, no login manager, nothing else besides chromium installed. Thanks again for any direction pointing folks may have
