I have recently changed PC computers due to a change in employment. I have the bookmark.html file from my old computer. I can view all the source code, but nothing happens when I try to import the file.
I receive a confirmation pop-up as though the bookmarks have been imported (see below), but they are not shown in my browser.
I have tried uploading multiple times with no success.
you welcome but the above image show up only when you go to brave://settings/importData not when you go to brave://bookmarks/
so copy brave://bookmarks/ in the address bar then press enter then follow the process above
if that what you get again then could you go to menu and create new profile and see if it act normally or not
the default exported/imported bookmark is html file structure but your file is json structure it’s not about file extension but about the actual file data so rename it would not make difference like if you rename video file to jpeg then if you opened it with your media player it still play the video normally
now go to bookmark and export it so you have the correct file in case if you needed it in the future you can open the exported file with an text editor like note pad or word to see the file difference
