can't save cookies gone back to Firefox

I have 4 or 5 special websites I log in each day ( banking) ... and for some reason I just can't get Microsoft Edge to remember my log in name ( AND PASSWORD)  Its pain to remember each password to log in, There was a time,  just recently,  where I could log in with the Edge remembering me,,   but after I messed around in the settings for cookies/cache  I just can't seem to find the "right combination" to get this to work again ..

So  I have gone back to Mozilla Firefox  ..,  as it remembers my login on each visit .

is there a video tutorial I could follow to get mine to work again as it did a week ago??
