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:

https://addons.mozilla.org/en-US/firefox/addon/disabled-add-on-fix-57-60/

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: Add-ons disabled or failing to install in Firefox - Mozilla Add-ons Community Blog

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:
