The star is blue only if you are on a web page that is listed in the Bookmarks Manager.

FreddMcD I am on the web page.

Here is an example. In a folder on my bookmarks is a web site called "Open port check tool" https://www.yougetsignal.com/tools/open-ports/

When I open the site the star is not blue. I go to the site bookmark it again and the star then turns blue when I use the recently created boookmark with everything the same except I place it in a different folder for comparison.

It is likely that the URL of such a bookmark redirects to another page when the star isn't highlighted. You can edit the location field of the old bookmark or create a new bookmark in such a case.

Core-el That is incorrect. The web address for both are identical https://www.yougetsignal.com/tools/open-ports/ The names are identical.

This suggest a corruption in the bookmark. Is there a method to check validity?

The best way is to start at that website's home page and manually go to the page you want. Once you are there, create a new bookmark.

FredMcd I am aware of how to fix the problem as my description of diagnosing the problem shows. The only difference between the bookmarks that I can see is the folder.

Can I perform a more detailed examination of the bookmark. I have a few others that do the same thing.

Hello mace2,

Would you please take a look at this thread and see if maybe you can find an answer there :

You can check for problems with the places.sqlite database (bookmarks and history) in the Firefox profile folder :

Either type in the address bar about:support or :

3-bar menu (or 'Tools') => Help ( next to the ? ) => Troubleshooting Information' and scroll down to 'Places Database' => 'Verify Integrity'

If "Verify Integrity" on the "Help -> Troubleshooting Information" (about:support) page cannot repair places.sqlite then remove all places.sqlite files in the Firefox profile folder. Firefox will rebuild places.sqlite and restore the bookmarks from a recent JSON backup in the bookmarkbackups folder.

• keep a backup copy of places.sqlite in case a new places.sqlite database has to be created
• http://kb.mozillazine.org/Unable_to_process_the_backup_file_-_Firefox

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

• Help -> Troubleshooting Information -> Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
• http://kb.mozillazine.org/Profile_folder_-_Firefox

The places database finds no fault the database is labeled sane. I am not sure about cor-el recommendation as that seems to be the entire profile modification of Firefox.

I still have a few bookmarks that do not show up a blue star.

Here is the result of "places database"
