A couple of months ago, I configured Firefox to load a local html file containing my commonly-used links whenever I open a new tab
This week I've been trying to find where I set this up. I cannot find this setting anywhere in the Firefox options. Somewhere there is (or was) a dialog box with an item that said something like 'Page to load in new tab'. Where was it? Could Mozilla have removed it in the latest upgrade?
I'm not using any extensions but LastPass, so it's not controlled by an extension.
