Refresh favicon in bookmarks (Firefox)
<p>Few days ago, I've changed the favicon of my website: it works well when I open the website:<a href="https://i.stack.imgur.com/hlZ2O.png" rel="noreferrer"><img src="https://i.stack.imgur.com/hlZ2O.png" alt="enter image description here"></a></p>

<hr>

<p>My website is also in my bookmarks, but it shows the old favicon:
<a href="https://i.stack.imgur.com/c8txO.png" rel="noreferrer"><img src="https://i.stack.imgur.com/c8txO.png" alt="enter image description here"></a></p>

<p>I already had a look <a href="https://stackoverflow.com/questions/2208933/how-do-i-force-a-favicon-refresh">here</a>, but answers did not solved my problem.
The solution is probably very simple, but I have not found anything so far.</p>

<p>Thanks!</p>
