"Close tab" when going back a page on the earliest page. "Reopen closed tab" when going forward a page on the latest page.

Theres a neat addon on firefox (which no longer works) that added the functionality to close the tab if hitting [page back] on a page theres no more back from. it was very useful when checking something really quick on a newly opened tab, to close it very conveniently. (The usecase assumes operating with a mouse that has utility buttons - say for 'back' & 'forwards', which i imagine many people have and use that way)

additionally i think a complementary logic would be to reopen the last closed tab (assuming it was close accidentally) by hitting [page forward] on a page theres no more forward after.

its a simple logic -
when the action of [page back] is performed, determine if theres a page before the current page, if not - [close tab].

when the action of [page forward] is performed, determine if theres a page before the current page, if not - [reopen closed tab].

let me know if its relatively easy to implement, or if you think its useful/ not worth the time.

This is absolutely something I need as well!

Close tab if I go "back" when there's no page to go back to.
