Download with mod manager button not working

[Riessa]

As you can see from the title I cannot download any game mods with mod manager. I have tried several game mods. I also tried different mod managers. Nmm, vortex, and mo2, mod manager button does not work with any of them. This has been going on for 2 months now. It started right after I subscribed to nexus premium. I wanted to try collections, but since I can't download with mod manager I can't. That was a big reason I got premium. I do not know what could be causing it. I am no tech wizard, but I have been modding games (mostly FO4 and Skyrim) for several years so not entirely a noob. Any help or suggestions would be appreciated. Almost forgot, my browser is Mozilla Firefox if that could be the issue.

Firefox is indeed the problem here. Instead of relying on Windows to map the download links to Vortex, it uses it's own logic. No idea why they did that, but this may help: https://modding.wiki/en/vortex/users/download-from-nexusmods#i-have-the-option-enabled-in-vortex-but-downloads-still-go-to-the-wrong-appdont-start

Thank you for your help. I set the nxm, but firefox still will not download with manager. Just to be sure I used microsoft edge (not really a fan) and it worked just fine. Guess I will have to use edge until I get firefox to play nice.
