GET FUCKING VIVALDI!!!
This Browser has DAMN NICE MOUSE GESTURES!

You do them while holding right click.
For example right click held and swipe/moving the mouse to the left/right brings you backward/forward.
There are several others and you can make them by your self.

Just browsing anything. IT'S FUCKING DAMN FAST.
INSTALL VIVALDI AND ENABLE MOUSE GESTURES! After aprox 3 Days you won't want to have any other browser anymore.

(Could've just simply said that I love the browser because of that feature. But this is DevRANT!)

FUCKING MOZILLA!

>over9999 times faster
-Ughm, okay, but what is the trick?..
-THE TRICK IS THAT NONE OF YOUR FAVORITE ADDONS WILL WORK!!!

Seriously this is fucking insane! Several of my addons which were essential for me to stay sane is gone and I don't even know how to live without them. And all this bullshit is happening because these idiots in Mozilla decided to enforce use of WebExtensions. For ones who unaware, WebExtensions is much, much poorer framework and many cool addons simply unable to work under WebExtensions because of its limitations.

Are you the one who loved the speed and joy of using mouse gestures? GUESS WHAT ­— IT'S GONE.
Maybe you made your browsing activity super efficient with use of the “Tab Groups” addon that used to allow you to group your browser sessions? SAY BYE-BYE TO IT!
And many more!

Most importantly, I cannot understand why would a company enforce use of a framework that will decrease functionality of a product.
Anyway, it seems like Firefox is not a browser for addon enthusiasts like me anymore; got to find a new one, any recommendations?

Firefox Quantum broke mouse gestures of any kind in Linux by forcing the context menu to come up on right mouse down, instead of up.

Lots of people love Quantum, but without a viable mouse gestures extension, it's unusable for me. I downgraded back to 56 until this issue is resolved.
