Let’s pretend example.com is paginated to 17 pages.
With my extension installed, if you typed example.com/1..17 in the url bar, it would open up example.com/1, example.com/2 … all the way through example.com/17. 17 tabs total.
An if you typed indeed.com/20..90..10, it would open up indeed.com/20, indeed.com/30, indeed.com/40 … all the way through indeed.com/90. So essentially, incrementing by 10 each time. 8 tabs total.
Syntax: website.com/<first page>..<last page>[..<increment>]
