If you open Desktop Firefox Browser and go to “Manage Your Extensions” (about:addons), you will see there a section “Recommended Extensions” with a list of extensions you can add to your Firefox. Every extension in it has its card with the extension name, its developer name, and other lines.
Developer name here is a hyperlink to the extension page on addons.mozilla.org. In this page you also see this extension card, which looks pretty like the previous one. The main difference is that the developer name, which is also a hyperlink here, this time leads to a page where all extensions made by this developer are listed. So we have two hyperlinks which look the same but lead us to the different places.
I suggest to change the way the extensions are displayed in “Recommended Extensions” section in “Manage Your Extensions” (about:addons)
