Error message says I must be using Firefox to install add-on - I am using FIrefox!

I'm trying to install the add-on <always ".com" - (in English)> and the following error message:

"Sorry, you need a Mozilla based browser (such as Firefox) to install a search plugin."

Which is a little odd since I've been using Mozilla exclusively for more years than I can remember. Can someone please explain why Mozilla can't detect that I'm using Firefox?

The Add-on is not available for the latest version of Firefox (or) Removed by the user.

Make sure that you do not block JavaScript.
Try install that search engine in Safe mode if it doesn't work in normal mode.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do not click the Reset button on the Safe mode start window or otherwise make changes.
