How to Fix Firefox Browser Not Showing/Wrong Bookmark Favicons

Sometimes, you may notice that after updating the Mozilla Firefox browser, the Bookmark favicons are either not showing up or you see them with wrong favicons. For instance, for the YouTube bookmark thread, you may either see a Reddit icon, or you may not see any icon at all. This is a common issue with all Windows versions and some of the common reasons why you may experience this issue, can be either due to an older version of the Firefox browser, when certain add-ons hijack the favicons, if the browser caches an outadated version of the favicon, or when the favicons file is corrupted. However, the good news is, the Firefox browser not showing/wrong bookmark favicons issue can be fixed. Let’s see how.

Method 1: Add a ‘/’ behind the link


This method may work more as a quick fix instead of a permanent solution.

Nevertheless, you can try the fix and check if it works:


Step 1: Launch Firefox and type the url (in the address bar) which has the missing/incorrect favicon issue and add an extra front slash (/) at the end of it.

For example, when you are typing the url , add an extra front slash at the end of it. It should look like this:


You can now see the favicon appear for the website.

Method 2: Update Firefox to the Latest Version


Step 1: Launch Firefox, navigate to the upper right of the browser, and click on the three horizontal lines (Open menu).

Once done, click on Restart to update Firefox to finish installing the update.


Once the update is installed completely, reboot your PC and check if you can see the favicons/correct favicons now.

Method 3: Force Firefox to Update Favicons


At times, Mozilla Firefox may fail to update to the previous website logos to new versions. In such situations, you can force Firefox to assume that all your favicons are outdated and update them automatically. Let’s see how:

Thereafter, copy and paste the below code in the new Browser Console that pops up and press Enter:


var fS = Components.classes[";1"] .getService(Components.interfaces.nsIFaviconService); fS.expireAllFavicons();

Now, exit the Browser Consoles, close the Firefox Browser and restart the browser again. You should be now able to see the favicons or the correct ones.

Step 1: Press the Win + E hotkey on your keyboard to open the File Explorer window.

Step 2: In the File Explorer window, go to the View tab, click on Show/hide and then check the box next to Hidden items.

Step 4: Now, go to the search field on the upper right of the window, type favicons.sqlite and search for it.

Once it appears, select it and hit Delete.


*Note – If you do not find *YourProfile* folder in the Profiles folder OR the favicons.sqlite file in the above path , you can try checking in the below path:

Now, launch Firefox and the favicon configuration file should be created automatically, however, they will be all generic favicons. Click on every bookmark one by one

Method 5: Clear Web Cache

Step 1: Launch Firefox, open a New Tab and close all the other tabs.

Step 2: Now, go to the top right side of the browser and click on the three horizontal lines (Open menu).
