and to load the last one when I start Firefox.
firefox (and also v57) is capable to this without extension.
Does 'Tab Session manager' do all this, because I've tried it with FF57 and can't get it to load a session?
as noted before you dont need a session manager for this.
but you can reload the last session when firefox was closed (if you set up TSM this way)
as GHM113 any time mentioned any session webextension is NOT able to save history for tabs, this is gone for an unknown period (needs API).
Tab Session Manager is from my view a decent alternative (MySessions is buggy, no further investigated).
MySessions 2.3 did not fix the lost settings:
IMPORTANT: the problem with resetting the settings by default is found and will be fixed in the near future.
tabZen is not my favorite, Tab Saver also not, i like OneTab for saving my investigations most, but i dont use it as a session manager.
60 , 600 and 1200 tab session
you probably never will open >99% of those again.
Tab Suspender extension automatically unload (kill/hibernate) inactive tabs. This action can free up your browser memory usage.
firefox (also chromium/chrome) is performing this itself. tabs are suspended and need to reload after certain time.

i am experiencing this feature when using my other profile with some more open tabs. from my understanding no need to install it.
