Mozillazine thread has fascinating practical, detailed suggestions about
how to jump sideways to SeaMonkey without functional loss.

I've done my best to summarise this entire situation for general Linux
users, filling in the historical background to best ability, here:

that might be worth considering:

o Waterfox: https://en.wikipedia.org/wiki/Waterfox
o Pale Moon: https://en.wikipedia.org/wiki/Pale_Moon_(web_browser)
