A toolbar which used to work is now not verified in Firefox and I can't use it. Can you help please?

more options

I have used Nectar both as my homepage and as an added toolbar for many years now. I have always it to be simple and easy-to-use (a great advantage for an ageing technophone!) and it was particularly useful in letting me know what stores I could shop with via Nectar to increase my Nectar points. Points were also accumulated for carrying out 'searches', another useful feature.

Over the past few months I have experienced continuing difficulties with this to the point where I contacted Nectar. They kindly added 'free' points to my account to compensate for the fact that I had been unable to use the toolbar or to shop via Nectar. They suggested I uninstall and then reinstall the upgraded version of their toolbar. I have tried to do so on several occasions but have been unsuccessful in being able to access online stores via Nectar and also to add to my points total using the Nectar search facility.

Having tried again, unsuccessfully, to reload the toolbar, I now find a message from Firefox saying "Nectar Toolbar could not be verified for use in Firefox. Proceed with caution."

Can you please verify this product so that I can continue its use? I do not know how else to over come this issue and would like things to be as simple as they were before this issue arose.

I hope someone can help - but please bear in mind my state of technophobia and explain things in a very simple manner for me (ie without the use of computer 'jargon' and technical wording!).

Thank you and hoping you can help.

For Firefox 40 that verification is only a warning message, the new add-on "signing" feature won't keep an extension from working in Firefox 40.

If that Nectar Toolbar just quit working in Firefox 40, I can only guess that it is due to a deprecated API that extension uses or other compatibility issue. Add-on developers who are registered with the official Add-ons website were warned about that API being removed from Firefox 9 to 12 months ago to give the developers time to fix their add-on before Mozilla removed the related code for that API.

Bottom line is Nectar needs to fix their extension to get it to work again AND they need to submit it to Mozilla Add-ons for signing.

In Firefox 41 add-ons that aren't "signed" will be disabled, but the user can override it. In Firefox 42 that override will be gone from Beta and Release versions - signing is mandatory for Firefox 42 and thereafter.
