What page are you getting for the new Tab page?

Start Firefox in Safe Mode to check if one of the extensions (3-bar Menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: 3-bar Menu button/Tools > Add-ons > Appearance
• Do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can look at this extension to set the new tab page:

• New Tab Override: https://addons.mozilla.org/firefox/addon/new-tab-override/

You can set the new tab URL via the Options/Preferences of the extension on the about:addons page.

You can look at this extension if you use the home page as the new tab page.

• New Tab Homepage: https://addons.mozilla.org/firefox/addon/new-tab-homepage/

Classic Theme Restorer includes this feature as well. You find "New tab page url" in the Tabs (2) section.

You can use pages like these:

• the default new tab page with the tiles is about:newtab
• the default home page is about:home
• for a blank page use about:blank
• for Super Start use about:superstart
• use the URL of a web page

See the about:about page for available about pages.

I was getting a swagbucks.com page but I was able to remove it and restore to my original settings. Thanks

That was very good work. Well Done. Please flag your last post as Solved Problem so others will know.

Note that the The System Delete list next to the question shows the SwagButton 207 extension.
