I am looking to turn on review checker and cannot see how to do it. I don't have the price tag icon displayed nor do I have any reference to Review Checker in my settings. I'm wondering if my version of Firefox supports it (133.0). Any ideas?

How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.
