That may be an option. I will have to test it before I give up on Firefox completely, although I fear an add-on that changes so much may break things in the long run.
I did test it some months ago, when I first discovered Australis. Back then it lacked many details that made me prefer to downgrade to a more stable channel, but I will try it before I completely dismiss Firefox. If it even really happens, because as much as I dislike getting things shoved down my throat, the alternatives feel even worse. In them, there's no customization at all.
I don't know why people take my comment so badly. I dislike Australis, not Firefox.
I have been using nightly builds of Firefox for years, with some short breaks when an unwanted change was being introduced. Sometimes the change was discarded, other times I decided to embrace it. I got used to the new downloads panel, for example.
Up until now, I have been able to revert all the changes they made, where I didn't want them. A big example of this is they keyhole back/forward button. I keep the Home button in between back/forward and the addressbar, so that they don't merge. In contrast, I did like the stop/refresh being combined, and I was ok with them being put into the addressbar. I use F5 to refresh anyhow.
But above all, I value customization. That's why I use Firefox, and why I choose to use it instead of Chrome or IE11. I like to see things the way I want them, and they don't usually match the designer's choice. As I said, up until now, the changes were either positive, or they did not affect me enough to reject them. Australis is something else.
With Australis, they are removing customization, in favor of a more unified UI across all devices. This has two issues, in my eyes, which are both based on one simple fact: I have a very large monitor, at 2560x1440px. And it could still be bigger. I have enough space in my screen to hold a webpage, multiple addressbars, and in those, keep all the buttons I would ever use.
I don't want an UI optimized to reduce space. I don't want an UI that looks the same in my desktop and my tablet -- they are very different devices with very different purposes. I want to put things where I like them. And they are taking that away from me.
By my principle, I want to use the closest thing I can get to the Firefox I Used To Love. So yes, PaleMoon is my top alternative so far. And don't you dare talk about chickening while posting as AC.
You must realize that the computer has it in for you. The irrefutable proof of this is that the computer always does what you tell it to do.
