Favicons for bookmarks broken since Edge v149 update

🚨 Update: workaround for the favicon issue

After testing, it seems in Edge v149 if you have "browsing history" set to clear each time you exit Edge, this is what causes the favicons to not appear, and also for some existing bookmarks to lose theirs.

To check, go to Menu > Settings > Privacy, search and services > Clear browsing data > "Choose what to clear every time you close the browser" (or enter edge://settings/privacy/clearBrowsingData/clearOnClose in the URL bar, then hit enter to go straight there).

If "browsing history" is enabled there, turn it off (the dot should be on the left) and favicons should then start working.  If not, you may need to either (1) close Edge, and delete your current "Favicons" and "Favicons-journal" files, then reboot or (2) create a new profile in Edge (which means having to export your passwords, bookmarks, saved addresses and save payment cards, then reimport them 😬).

Hopefully Microsoft can get this sorted, either by restoring the pre-v149 behaviour, or by adding a new "keep favicons when clearing browsing history" option, as currently the workaround means having to keep your browsing history recorded.  However, you can clear this (from the Edge menu, click "Clear browsing data" and then set time-range to "All time" and make sure "Browsing history" is checked; it's up to you if you wish to check any other options there), and from my testing, the favicons do not disappear.  It is only if you ask Edge to clear the browsing history when you exit the browser that causes the issue.

💡 To find where your Edge profile is located, type edge://profile-internals/ in the URL bar, then press ENTER.  Then click on the "Default" or "Profile 1" heading, then look next to "Profile path".  In that folder is where you should find the "favicons" and "favicons-journal" files you can delete.  Make sure Edge is fully-closed first, and I'd also suggest doing a reboot after deleting them.

💡 If you have more than one profile, tap the profile icon in the top-right to see which you're currently using.
