I have tried reinstalling Ffox ad nauseum but the zoom settings will not 'stick' and don't survive a quit and restart. In an effort to sort this I have installed Firefox 128.5.2esr but now the zoom setting does not work at all. Tried everyting, including deleting all ref to Ffox and reinstalling but nothing works. Note that I install in the admin account and run as user. This worked fine with MacOS Ventrura but fails with Sequoia. If I install from the user account with admin privileges zoom does work but fails on a machine restart. Safari, Vivaldi etc all work as expected. It's only Ffox that has the problem. Shame as I've used it for years. If I can't solve this I shall have to go over to Vivaldi and give Chromium another shot in the arm. Any help appreciated. MAcOS Sequoia 15.2 Mac Mini M2Pro
