Is there a way to go back to FF 88 if you upgraded already?

I'm wondering if there is a way to go back to Firefox 88 if you have made the mistake of updating to Firefox 89?
Kubuntu 18.04

Every version of firefox ever is here https://ftp.mozilla.org/pub/firefox/releases/

You can run it from the downloaded folder.

Some options:
A) Use the ESR version of firefox (78) via PPA
ppa:mozillateam/ppa
Or via Snap
https://snapcraft.io/firefox
(Selecting the esr branch) but this particular package probably won't follow your KDE desktop look and feel settings

B) 'pin' firefox to the desired version - this can be done in Muon, and Synaptic, or manually.

C) Use the self-contained binaries Bings linked to above
Will take some minor setup to make it the default browser, create menu entries, etc.

I was able to install 88 with Snap, but I must have done something wrong as I can't import bookmarks etc.
Thanks though.
If I could being in passwords and bookmarks I'd have it made.
