Don't know Chrome, but find it easy enough to do this manually: just hovering the mouse near the left end of the tab bar, or in the right half of the tab bar, then middle-clicking away (click/click/click/click/... - 3 per sec) to close a bunch.
What middle-clicks shall do is a userconfig:
either F2 > Browsing > Tabbed Browsing > Tab bar or
Tools > Mouse Accelerators > Firefox

Update 2019:
