It's pretty great. Works like it should and it was just the extension I was looking for. Thanks.

FUNCIONALIDADE E OTIMIZAÇÃO ,OTIMIZAÇÃO!

Я всегда хотел сменить страницу при создании новой вкладки, и благодаря этому расширению это наконец получилось! Работает отлично, пока что проблем не было

Das Add-on ist Spitze.

Eine Frage habe ich noch:
Bisher war es mögllich, durch Klicken in das Adressfeld die Anschrift "about:blank" zu markieren, dann die neue Adresse einzugeben, die (blaue) Adresse "about:blank" wurde durch die gewünschte neue Adresse ersetzt.
Seit Firefox 60.0.1 ist das nicht mehr möglich, "about:blank muss händisch gelöscht werden.
Mache ich etwas falsch oder gibt es hierzu in FF eine Einstellmöglichkeit?
Vielen Dank

It opens local html files but the css doesn't load

Works as intended.

great add on keep up the killer work!

Found a reference to this newly updated extension and it works perfectly for my needs: I selected the option (among many) to have any blank opened tab I open show my custom home page. Thanks for a great product design!

Appears to work as advertised.

Exactly what I wanted. I hated the Top Sites page that Mozilla introduced when they disabled my previous New Tab addon.

Does as described. Wish it was a bit more instantaneous, it seems to go through some short redirect process that is about a second long.

I love this app as the fact that I can always choose My Homepage that I set up and not see different ones from browser choosing or many thumbnails of past webpages visited. Every time I update Firefox, the next step I make is to make sure that New Tab Override is enabled because there is no life without it.

Deactivating the extension replaces the current tab content by a default new tab, destroying all data one is working on and even literally erasing the tab from tab history (no way to use Back). Activating the extension instead closes the current tab. Even now, the tab is completely lost in the void, because ctrl+shift+t causes a "new tab" be opened INSTEAD of the previously closed tab. (EDIT: The previously closed tab is only lost due to a hazard when I press ctrl+shift+t twice very fast.)

Other than that, the addon does what it has to do, and I appreciate the option to gain tab focus instead of the navigation bar. One last thing i'd find very useful is if typing into the address bar before anything gets loaded postponed the process of replacing address bar (deleting anything I've typed) and taking the focus away. Not sure if firefox even provides so much API to achieve this.

// Reply: Well the issue is critical and deserves at least an acknowledgement in the description, as it's an anti-feature. Honestly though, I haven't seen WebExtensions implementation, but I don't believe you at all. I can imagine several workarounds, neither of them were even considered. Is there no API whatsoever to access the last closed tab history, so that you can offer a way to manually re-open the lost tab? Is there absolutely no way not to process your addon when the user presses Ctrl+Shift+T? Is that specific event impossible be detected? Can you not let the default implementation (optionally) load first before redirecting to the user specified site? Also the issue could be reported to WebExtensions devs... Completely blocking the "re-open last tab" support is definitely not acceptable as a final decision. (But I know the WebExtensions suck, there are so many other addons that no longer work even in theory in the new Firefox.)

-> Okay so I decided to try to fix my issue myself and even though I found a WebExtensions solution, there was a bug that I couldn't fix. Still, some safety workarounds could be made. Luckily, I found a workaround instead: disabling the focus setting solved the issue, because it still focuses the new page anyway (the setting is broken), thus it works exactly as I wanted. The referenced issue is here: https://github.com/cadeyrn/newtaboverride/issues/167

Sweet and to the point! UI could use a bit of love but, I'm not going to be staring at it for hours at a time so no complaints!

It does exactly what you expect. Yet it explains clearly why some features are not implemented (such as the local url).
