New Hackbar — Alternative to Hackbar addon in Firefox Quantum This link is for anyone who cannot read to the end.

A beautiful morning in this week, when I turn on my browser as daily, my hackbar in the Firefox suddenly disappeared. The interface of Firefox was seem better but that is not importance when my some addons did not work, especially the Hackbar.

I cannot work if my browser misses the hackbar, it have gone with me for ten years. After that, I tried to find any solutions to use back the hackbar addon. However that seems hopeless.

Cannot find the hackbar in the store
The addon’s status
And the author also said cannot help me :(

So, nobody does, I do :)

The new version of Firefox (Quantum) is cause of this problem. They move to new architect and don’t support the XUL addon anymore (the type of hackbar addon). It seem to be becoming similar to Chrome, at least in two new features: multi process and just support webextension addon.

There are two problems if I want to build my own hackbar addon in Firefox Quantum:

  • Interface: Firefox Quantum is not allow to redraw its interface, you cannot create a new toolbar like the original hackbar. So, I must move it to sidebar.

It seemed impossible, but after two nights hard work, I release a very first version, I think it is an acceptable version. Please try to use and give some feedback.
