Anyone else having this issue?  FF 43.0 Yahoo edition 1.30 disabling some addons like Yahoo Toolbar, Microsoft .NET Framework, Epson Webprint, & a few more.

Oh yes.  Many people are reporting the same thing.  Mozilla help forum has many requests for help. I only had one extension that had the problem.  I un-installed it and then re-installed it and that solved my problem.  Here is one link about the Yahoo Toolbar and others.

I have reinstalled but a refresh or restart of FF would disable them again.

Give this a try:  Open a new tab in Firefox, then type into the address bar "about:config".  Agree you will be careful.


Find the entry "xpinstall.signatures.required" - right click and 'toggle' to False.  You may need to reload FF and perhaps reinstall the add-ons.
