You have to install the Add-on Bar (Restored) extension to get ForecasterFox working.

Note, you have to install ForecasterFox immediately after a fresh install of the Add-on Bar (restored)

You can download the latest ForecasterFox below

Not sure if the first part worked, since it came up with the error 'Firefox prevented this site (addsons.mozilla.org) from asking you to install software on your computer.' but, as far as I can tell, the 2nd part 'did' add the Forecasterfox Addon is back! Thanks!

Tip: Mozilla nor we are responsible for the incompatibility between newer versions of Firefox and add-ons. Most of the times after the release of a new Firefox version, add-ons may become incompatible. It's up to the developer to address these issues and update it accordingly. You can contact the developer from their add-ons page.

'My' tip: If Firefox is as good as it claims to be, it could evaluate each add-on before the upgrade is applied and alert the user of any problems, such as possible incompatibilities.

That's a really good idea, but I (nor this community) is not the one to make that decision. I think that would be a good idea for a bug.... Worst thing that happens is that it gets marked as WONTFIX.
