Palemoon seems too far away from the stock firefox user experience and isn't compatible with my config and most of my addons.
I've tried Waterfox earlier, copied over my ff profile and now that I installed it again to try it out it worked perfectly with that profile with especially all the extensions I have in FF.
I thought, cool, but I need to update that profile. Backed up the profile and replaced copied it over anew from FF. Cool, but the addons didn't work (incompatible). So I reset it, copied over everything but addons and extensions files and folders - worked, but all the tabs I had open in firefox (about 300) wouldn't load now. I fixed that by creating bookmarks of all tabs so I could just close the windows and end the broken session, which worked, but I found my addons wouldn't work either.
I then got back to the backup of the old profile with the addons that worked, but they didn't. Still incompatible.
The logical conclusion here is that I have to invest some time, figure out alternative addons and take the time to really configure Waterfox rather than copying everything over.
But I have some hope it might be due to the certificates, because again, it worked 20 minutes ago with exactly the old profile I made a backup of. Does anyone know? The "studies" thing that fixed addons in Firefox lately obviously isn't available here. Also it's hard to believe there is no NoScript for Waterfox. The search doesn't find any though. Also some Addons appear to be enabled, but where are the menu options and fucking icons?
I remember there being trick to make it work, I was just too lazy to try them out last time. I have no hope the solution is still among those 300 tabs.
