Yes

Describe the issue you encountered:
Users don't tend to add http/https suffix while manually adding a bookmark. Would simply type the domain name and add a bookmark. Adding like this causes a blank page favicon to the bookmark and doesn't change even after visiting the bookmarked link.

Expected behavior:
Should auto prefix http/https and update the bookmarks when visited, also favicons should be created after suffixing http/https to the bookmark upon visiting them

• Platform (Win7, 8, 10? macOS? Linux distro?):
  Windows 10 x64

• Brave Version:
  master branch

• Steps to reproduce:

  1. Add a bookmark manually in about:bookmarks by clicking the star+ icon
  2. In location enter the domain name without the http/https suffix (eg: brave.com)
  3. Added bookmark shows a blank page favicon, visiting the site by clicking the bookmark doesn't update the favicon
  4. Add a new bookmark with a trailing / after the domain name (eg: apple.com/)
  5. Visit the bookmark added in step 4, doesn't show the orange bookmark icon in the URL bar
