Ddg will not back from open site to search results

[analityk]

This issue occured on Redmi note 13 pro 5g (latest updates) on Firefox but only in genereal mode (in incognito mode issue not occured). I have uBloc origin only and I have select my own cookies blocking settings (all no visited pages).
How to call "error" (I hope this is not desired behaviour):
open new page;
type something into ddg search;
visit one page from fund pages;
spen a while here (sometimes 10 sec, sometimes 60);
wana bak to previous screen?
nope, look at ddg AI tab about how do you provide safety futures and go to ai searching.
Nope ddg, solve this quick.
