I only used '''snap''' package manager for my Ubuntu TB installation because the''' apt''' equivalent was an older version than that on my previous Windows 10 TB. Now it seems to me that '''flatpak''' may be a more memory-efficient and secure way to enable each application to have its own set of dependencies - sometimes using a different version of a dependency used by other applications - without unnecessary duplication/storage bloat and consequentially faster wearing out of SDD drives. At present my '''snap''' TB is on version 91.11.0, as is the current '''flatpak''' version of TB. I had a lot of trouble migrating TB from Windows 10 to '''snap''' on Ubuntu. https://support.mozilla.org/en-US/questions/1309930 I lost a share of stuff and I don't want the same thing to happen again. So is there a secure, tried and tested procedure for a TB migration from '''snap''' to '''flatpak''' ?
