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

Don't waste your time, this add on is useless. I use a custom HTML menu that is local. This won't let you use a local HTML file, only live web content. I'd also like to know why we need an add on for something FF should do in the first place. I'd give it zero stars if it would let me.

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

This works until i closed the browser. When I open the browser again it does not work. Don't waste your time

No work, no extension visible

Doesn't work at all

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!

totally useless ... it doesn't have any effect on anything!!!

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.

Once this is enabled, tabs will only open momentarily then immediately close.

When using the setting to not close the window when closing the last tab, three tabs are opened.
