just white page

Didn't seem to work at first, until I found out that due to Firefox restrictions, local files cannot be handled by add-ons. My homepage was a local file... I solved that by adding it to my (local) web server. A warning that local files are not allowed would have been useful!

İşini basitçe yapıyor. Yeni sekme sayfasında başlangıç sayfasını görmekten hoşlanıyorsanız yüklemelisiniz.

I received a very quick and precise answer. Searching the web previously had answered questions I didn't ask. I am delighted. Thank you Ben.

This add-on was easy and fast to install and did exactly what it said it would do. Now when I open a new tab it is my homepage -Perfect!

Works perfectly with Firefox 61.0.2 (32-bit).

Does nothing. A blank page appears, which can also be selected in the Quantum "options".

Bo tak lubie

This did what I expected, so good.
Then I found this pref in about:config
browser.tabs.insertAfterCurrent
The default is false! Make it true, and no addon needed!

not working all of a sudden...
