Did you back up your profile? If not, you may have difficulties
reverting, without data loss. I forget where it started happening
(perhaps 2.53.0), but as with Firefox, profiles are now no longer
backward compatible.
But half of my dear extensions used for years stopped working.
Extensions are becoming increasingly difficult. Firefox abandoned use
of XUL-based extensions beginning at Firefox 57 (in favor of Google's
WebExtensions), and Thunderbird has now done that since 78.0.
To a large degree, most extension developers have also abandoned
support of the older structure, and all XUL content has been removed
from addons.mozilla.org. Many (but not all) Seamonkey extensions can
still be found at addons.thunderbird.net/seamonkey.
There is also an extensive collection of Firefox, Thunderbird and
Seamonkey extensions through the Classic Add-Ons Archive at
https://github.com/JustOff/ca-archive .
As for what may work or not is going to depend on the extension. I've
found that I can continue to run pretty much everything I want, from
one of these sources.
It's also worth noting that for several of the most popular
extensions, the release notes
https://www.seamonkey-project.org/releases/seamonkey2.53.6/ indicate
current status, and links for download. These include uBlock Origin,
NoScript, Session Manager and Enigmail. I've also found that PrefBar
still works, but that the only source for that is from the developer's
web site, and not any of the sources noted above.
The release notes also indicate that for some extensions, the coding
may be fine to run in 2.53.6, but that in the underlying .XPI file,
they may have a max version setting that won't allow for running past
a certain version. It's been a long time since I've needed to do it,
but it is possible to edit a .XPI to set max version to be compatible
with the version you're running.
Some of them have new WebEx-compatible updates though.
Does anybody know which future Seamonkey version is planned to
support WebEx ?
WebEx is planned for 2.57, but isn't imminent, and developer notes
indicate that there hasn't been any serious work started on
implementation.
I do have an alpha of 2.57 installed, and in the current status, the
browser pretty much works, but that's it. The Mail and News client is
not working, and there's no support for extensions, whether XUL or
WebEx, and I don't expect any changes any time soon.

It looks like the end of SeaMonkey .....
