LIbreoffice not pointing to default browser

I used Opera as my main browser for some time. No I’ve gone back to Firefox (FF). When I click on a hyperlink in Libreoffice, it opens up in Opera and not Firefox. Is there a way to tell Libreoffice to open all links in FF ?

Your operating system controls which application opens when a link is clicked.
This is not controlled by LibreOffice.
So check your operating system settings.

You also need to check the browser settings in each browser.
You may have two browsers set as the “Default browser” and they each take back control each time you use them.

Thanks for your answer. In fact I went to Settings Manager and clicked on Preferred Applications. I had it on Opera. Now I put it on Firefox (link should read: /usr/lib/firefox/firefox %u
Thanks again.
