Is there any Firefox extension similar to Chrome's The Great Suspender?

Basically it suspends tabs that are not actively being used, allowing you to have a lot of tabs without consuming all your memory and CPU processing.

Tab Suspender (memory saver) seems to be a pretty good alternative.

    The author of that add-on states "This extension is deprecated; For FF >= 58 switch to my native tab suspender add-on" (which is the one mentioned in @kenorb's answer.

    While deprecated it's technically still compatible with FF 58 Mar 6, 2018 at 0:02

There are several options:

  • Auto Tab Discard (Compatible with Firefox Quantum)

    Use native tab discard method to automatically reduce memory usage of inactive tabs.

  • One Tab (Compatible with Firefox Quantum)

    OneTab - Too many tabs? Convert tabs to a list and reduce browser memory

  • Dormancy (Compatible with Firefox Quantum) [Experimental]

    'Retires' tabs that have gone unused for a while, freeing up that memory. It then restores the tabs to life when accessed.

  • UnloadTab (Not compatible with Firefox Quantum)

    Unload inactive tabs, save resources.

  • Suspend Tab (Not compatible with Firefox Quantum)

    Suspends background old tabs automatically to save memory usage.
