Unlike the "Custom New Tab Page" extension that hasn't been updated in 5 years. This extension actually does what it says. Was able to set google to new tab with this extension.

正當我苦惱FF怎麼不能自由設定NEW TAB時，我想起了FF有許多好用的外掛可以使用

It was working fine. But, no longer. I have chosen custom URL (https ://www google com /advanced_search). It doesn't go there upon opening new tab.
It may have been updating firefox to 136.0.4. (spaces added to URL - review does not allow otherwise)

EDIT: Okay, now I got it work. I had to uninstall it and re-install. Something Firefox did somewhere broke it, but I can't say what. I certainly never touched it.

give me the feature i miss in vanilla firefox

The Bets! But, I can't donate through paypal cus they charge a fee! Suggest Venmo or other donation platform because PayPal is also run by APartheid NaXis!

Just new url for new tab, easy, perfect working with just the right permissions. Thanks for your work.

Finally... Why is Mozilla insisting on NOT allowing this setting by default is beyond my understanding. Many thanks to the developer :o)

this is legit. <3 thank you
