HI TcBrkr, I understand that you would like ti install a previous version of Firefox until Norton comes out with a compatible update to the current version of Firefox. Make a back up of your profile:

And try these steps: Install an older version of Firefox

If you want to use an up-to-date version of Firefox that can still run the current Norton Toolbar, there is another option. You could consider using a different variant of Firefox called the Extended Support Release (ESR) for the time being. ESR is designed for companies that require a longer cycle time between feature changes, but anyone can run it.

ESR currently is based on Firefox 38. It will get security updates over the next several months, but not get new features, so changes in Firefox 41 related to add-on compatibility will not kick in for quite a while.

Norton is likely to continue to support ESR until the new toolbar update. After that, I'm not sure what they will do because normally they only support a small range of versions.

If you decide to try it, here is how I suggest installing it:

Clean Reinstall

We use this name, but it's not about removing your settings, it's about making sure the program files are clean (no inconsistent, corrupted, or alien code files). As described below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.

(A) Download a fresh installer for Firefox 38.3.0esr from https://www.mozilla.org/firefox/organizations/all/ to a convenient location. (Scroll down to your preferred language.)

(B) Exit out of Firefox (if applicable).

(C) Rename the program folder, either:

(64-bit Windows folder names) 

C:\Program Files (x86)\Mozilla Firefox

to 

C:\Program Files (x86)\Fx41

(32-bit Windows folder names) 

C:\Program Files\Mozilla Firefox

to 

C:\Program Files\Fx41

(D) Run the installer you downloaded in (A). It should automatically connect to your existing settings.

Success?

Note: Some plugins may exist only in that old folder. If something essential is missing, look in these folders:

  • \Fx41\Plugins
  • \Fx41\browser\plugins
