 Setting extensions.torlauncher.control_host to "" and
 extensions.torlauncher.control_port to "0" solved the problem.

Comment (by speedtester):

 I'm having high cpu usage with version 9.0.1 only when using a profile
 with torlauncher.prompt_at_startup and start_tor set to false, to access
 clearnet or other proxies.
 Tried setting versioncheck_enabled to false, it helped once, but maybe
 I've changed something else too.
 Since ever then, I can't figure out what setting helped, as I can't fix
 the other profiles.
 I've figured out the below 2 threads are the hoggers:
 -firefox.exe!Ordinal0+0x11x0
 -ucrtbase.DLL!o__Clpow+0x10

 Hope it helps.

Comment:

 The previous poster (although 4 years ago) shouldn't have closed the
 ticket with new status `worksforme`. With all due respect, unless I missed
 something (search `site:torproject.org "douggard"`), I don't think
 `douggard` is a developer who should close tickets that way. Looks like a
 mistake.

 `toggle extensions.torbutton.versioncheck_enabled to false` is a
 workaround but not a bugfix for this ticket.

 This issue as described in the original ticket is still happening.
 Therefore reopening.

 Could it be related to 10 years Firefox upstream unfixed bug
 [https://bugzilla.mozilla.org/show_bug.cgi?id=508427 High CPU on Linux
 even when in the background, possibly due to frequent polling]?
