Noble / Waterfox problem

[Grizzlly]

Hi All

I'm having real odd problem with Noble / Waterfox G6.0.9 (since last Noble 
update) that IIRC included the WaterFox update to G6.0.9

Every site, local file (i.e. my home page), tab or link returns

Tab has crashed, click to restore, or some simular wording

My normal WayerFox page has five tabs open four are sited the fifth is home a 
local *.htm file

nothing I do makes a difference

I can run the exact same WF G6.0.9 on Jammy (same box duel booted) with no 
problems they have used the same (symlinked from Jammy to Noble) 
~Home/.waterfox since I started testing Noble (it keeps bookmarks, homepage, 
passwords and history synced)

Any one else seeing this ?

BTW even the Waterfox support page returns "tab crashed..."
