so, taking a look out there at tab manager extensions, it seems that there is none with no 1 star review because of tab loose
luckily, native tab groups do the job, but something a little more sophisticate would be nice
does anyone know any tab manager extension that is not session manager / onetab?
my issue was with onetab, I lost everything, and also session manager has reviews that tell it's not continued anymore, and some people argue about losing their tabs
ok I answer myself: https://addons.mozilla.org/es/firefox/addon/tab-groups-helper/
it's a bit intrusive, but well
