Please edit your Original Post (“OP”) above, in order to include:
- Brave Browser version numbers
- Operating System version numbers
In a Brave Browser New Window, go to:
brave://local-state
Search for:
default_browser_infobar_declined_count
The value may be a 0 or a 1 . . . for example:
"value": 1
The value of 1, means, that you saw the Default Browser prompt and declined.
IF the value is 1, and the problem remains, then . . .
You CANNOT edit the “Local State” file in the window that you see at brave://local-state
In order to edit that “Local State” file, you need to exit / quit everything . . . and I prefer to restart the computer.
Before running anything after the startup, locate that “Local State” file. Example > Windows OS:
C:\Users\username\AppData\Local\BraveSoftware\Brave-Browser\User Data\Local State
Use a text editor to open that file. Search for:
default_browser_infobar_declined_count
That will be in a mass of information; on my Mac, looks like:
Set the value to 1
Save the file; close the file.
Start up Brave Browser and . . .
If the problem remains, then repeat the steps and set the value to 9999 ← re a related post here at the Brave Community.
