Download failed. Please check your connection. Theme Edition

Hi,

I am using Waterfox and I was trying to install a theme from addons.mozilla.org and i got this error:

Download failed. Please check your connection.

I know that’s not the error because my internet is working, so I open the link behind the install button in a new tab. There it says:

Watefox prevented this site from asking you to install software on your computer

I looked at some other forum discussions and found out about a hotfix here:

But it still doesn’t work. I’m still getting an error. Does anybody know how to fix this?

The details are available in this blog post: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/

The official solutions available work in Firefox, but we can’t really say anything for Waterfox. You should look for help in the Waterfox support channels, or switch to Firefox :wink:
