Worthless Firefox "update" has disabled NoScript (which Mozilla's own Help articles recommend as a way of stopping Firefox hanging) and BarTab (which stops all tabs loading at once). Now it's been hanging for more than a quarter of an hour and if I close it, I'll lose something I've been working on for more than an hour. Will post a separate topic about how to stop it hanging now and save the article, but how do I get back to a working version of Firefox and stop them trying to shove the other version down my throat until the add-ons needed to make it work are ready? Yes, I've read the patronising article where Mozilla wag their fingers at anyone who dares to question their forcing a substandard new version of Firefox on people, but in this case, the new version and its incompatibility with vital add-ons is definitely what's causing the hangs.
