FF 142.0.1. We have used FF fir many, many years, and NEVER, that is NEVER, been able to ad an extension to our toolbar. Yes, we have read myriad posts and sundry blogs where most of the advice we see is totally useless because the things we are supposed to do not exist in our FF. We can’t add in the customise palette, the extension manger Pin to Toolba, settings, et ceteras. So, how do we add an FF extension to the toolbar in FF 142.0.1? Thank you
