Can't find browser.newtab.url file to stop Yahoo from opening in new tabs
Hi, Yahoo is hijacking my new tabs. So annoying! I have followed your solution but where I need the file - browser.newtab.url I can't find this file with the instructions given. It doesn't show up. How do I stop Yahoo from opening new tabs without this file? Thanks.

The browser.preferences.inContent is no longer supported in Firefox 42 and later (bug 1140495), so it is not possible to open a standalone window by setting this pref to false.
You can possibly create a button on the Bookmarks Toolbar to the about:preferences page and hold the Shift key and left-click to open the page in a new window or tear off the tab with the about:preferences page (Tab bar: Move to New Window).
You can look at the Classic Theme Restorer extension.
- General UI (1): Open options page (about:preferences) in a window (v2)
If that isn't working or the choice is missing then you might be using a theme that isn't supported. You can check that by switching to the default theme.
Start Firefox in Safe Mode to check if one of the extensions (Firefox menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox menu button/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
