Just started using the new version earlier today. I don't like the new tab forcing me to the Firefox search page. So now, instead of one click to open the tab then start searching, I have to click a second time (the home button) to get to my search engine of choice.
Software, especially a browser, should not restrict my ability to choose how to use it. Prior to this update, the new tab always opened with my home page. I have no idea why that has to change now.
Will I stop using Firefox? No. It's been my go to browser for more years than I care to remember. This is just one of those "corporate decision" things I find annoying.
Thanks for listening!
