Chrome and Opera only open a tab when it's truly needed. I need a browser that will open 25 tabs, not on a contingency basis, but really open them.
I've tried Firefox and Pale Moon. They do load all the tabs, BUT they get all tied into knots when I give them 25 tabs.
I'm not going to use the browser for general research, only to open specific websites that don't have advertising, etc. But I really do need to open all 25 tabs at once. I'm open to using an older version of a browser -- this project has a limited time scope.
