No home page settings
I am switching from firefox to firefox-esr. Version 147.0.3 to 140.7.0esr, start firefox with --allow-downgrade which mostly works. What does not is the "Home default" page, it is blank and can not even be configured to what it was because the settings page is also blank, nothing below "choose what content ...".
I have done this on 4 machines now with same failure for the home page. settings. My previous workaround was new profile and import data so the setting page is therein ESR. This is a far harder than it should be there being no single export-import. I had to export import history with a third party plugin and cookies the only method [I found] was to copy the sqlite file. Others like password export-import are fragmented.
