In a Brave Browser New Window, go to, one-at-a-time:
brave://settings/content/siteDetails?site=https%3A%2F%2Fyahoo.combrave://settings/content/siteDetails?site=https%3A%2F%2Fconsent.yahoo.combrave://settings/content/siteDetails?site=https%3A%2F%2Flogin.yahoo.combrave://settings/content/siteDetails?site=https%3A%2F%2Fwww.yahoo.com
and for each of those site details settings pages, click the Reset permissions button.
Next, take a swing at:
‘Browser keeps signing out! - #2 by 289wk’
After all that, in a Brave Browser New Window , go to, one-at-a-time:
brave://settings/content/siteDetails?site=https%3A%2F%2Fyahoo.combrave://settings/content/siteDetails?site=https%3A%2F%2Fconsent.yahoo.combrave://settings/content/siteDetails?site=https%3A%2F%2Flogin.yahoo.combrave://settings/content/siteDetails?site=https%3A%2F%2Fwww.yahoo.com
. . . and for each, scroll down to JavaScript and set that to Allow. (Note: After setting the 1st of those 4, to Allow, you might discover that the other 3, are also set to Allow ← the general idea is, that all 4 are set to Allow and you are either setting them so, or verifying, at this point.)
And maybe . . . when you have done all the above, and you visit ‘https://login.yahoo.com/’ - and you attempt to sign on, and then you may still have trouble . . . then you might need to click on the Site Specific Brave Shields Lion icon that is adjacent/nearby the right end of the Brave Browser URL address field, and under Advanced controls, DISABLE Block fingerprinting, and then reload ‘https://login.yahoo.com/’.
