The latest update 72.2.1 hijacks navigation. For example, I open a Windows program that has an update available. There is a link in the program to go to the program website to get the update. After selecting the link the browser launches, but instead of going to the website the Speed Dial home page loads. This happens with various links that are suppose to go to specific websites, but the Speed Dial homepage loads instead. After disabling Speed Dial add-on, the navigation works correctly.
Found a workaround: Copied and pasted the Speed Dial page URL into the Firefox homepage Custom URL field. Then disabled the "Show Speed Dial on startup" in Speed Dial settings.
