After installation, I went through the add-on management settings and restarted FireFox and it worked.

Finally a custom new tab extension that work flawlessly!

No white flashes like others and no unable to open because of FF security.

Like another reviewer wrote: option to set the focus on navbar OR page content

Great work! I hope this extension is maintained.

Excelent !!!
It also has the option to set the focus on navbar OR page content

very good use it for years! it will be great if on new page could open selected all url text... what I do for select full ulr on new tabs:
- configure to focus on URL bar
- click on + (to open new tab)
- click on another tab (always opened)
- click back on tab that i opened and all URL text is selected

Was working great until I had to clean up a virus yesterday. Now a new tab gets loaded, but it is a blank page. I think an av program ended up changing some firefox settings ?

Edit: works again after refreshing firefox!

Works fine, thanks! But prevents Firefox Multi-Account Containers from working properly. Issue filed on Github.

Excelente extensão. Permite que eu selecione como desejo abrir uma nova tab.
