Will not allow loading local files on Ubuntu / Linux.

No, "Mozilla doesn't allow this functionality" is not an answer. I have a different extension, with the same local file, working perfectly fine on Windows 8.1 but it refuses to load on Ubuntu. This extension doesn't even make an attempt to load the file. It's HTML, CSS, JS so the semi support doesn't work (and isn't a real fix because I want changes to be made immediate which is why it's a local file in the first place). The only use I have for this extension does not work so it is immediately uninstalled.

-------------------------------------------------------------------------------

Edit: I don't think I can reply to developer comments so I will here instead.

Firstly, I don't need to make a GitHub issue because this isn't GitHub. This is the review section of mozilla.org where I review the extension I downloaded that doesn't do what I wanted it to. Secondly, I did say exactly what is wrong. If the path does not start with http:// or https:// the extension refuses to load without even trying. This is not a technical reason, this is a developmental choice and why the other extension loads on Windows (because it doesn't give up the moment I input my file path). Lastly, the other extension works on Windows 8.1 and 10 merely by inputting file:// (path to file) despite it too saying it's not supported. The steps to reproduce the two star review are: 1) choose new URL 2) input anything that's not http:// or https:// 3) immediately uninstall and leave a poor review reflecting this design choice.

Thank you for making the extension (I didn't rate it one star) but the extensions design choice makes it unusable for local file hosting which works despite it not being officially supported. All I need(ed) it to do was auto open an HTML file from my machine (not cache but actually open to access ./css, ./js, etc) but I have since worked around this issue.

Still awesome.Thank you!!!

JUST THANKS

Muito boa, ajudou e muito com o fato de uma extensão não ter passado para WebExtension.
O único problema é que necessitei criar aquele servidor web local, poderia aceitar arquivo local HTML.
Mas isso é problema do Firefox, devemos pedir para eles desenvolverem melhor essa webextension.

Deveria não bloquear o usuário de ter, mas avisar dos riscos e permitir o usuário escolher

Ao menos quando as WebExtension são limitadas ainda.

Cumple con su función, aunque una de las opciones, la de no fijar el foco en la página, sino en la barra de direcciones, actualmente no funciona.

Thank you Soren for updating your much-beloved extension to the new FF - I still hate FF for all the many extensions that I lost and that have never come back. Damn you Mozilla.

You are appreciated! Thank you for taking the time to update all the code and still be here.

good rlly

I don't think at all it is a miracle or like it was before maybe, i just cannot for the life of me get over this strange event. Now, .... Now, I have seen everything...... Heh!

i can keep so many tabs so well organized with this

Я все люблю.

So good

WOW SUPER,THANK YOU !!!!!!!!!!!!!!!!!!!!!!!

It would be useful to see in the settings of this addon what exactly the local file is currently used

Thank you, Soren! I just posted on my fb feed, thanking you!!
Firefox: you can be so annoying. Why did you disable my chosen homepage each time I create a new tab so that I only see your generic Firefox default homepage? Thank you, Soren, for creating a workaround with New Tab Override that brings back the ability to change the page which is shown when opening a new tab. OMG!

porque es muy bueno creativo y facicil de utilisarlo
