Not sure if this is normal, but I have very noticeable lag in the search/address bar autocomplete which does make the whole browser feel a bit slow (MacOS Sierra, using Developer Edition).

And since we are here, the prompt/dialog windows in FF are still not native looking too. These are my two major complaints :)

This isn't just a problem with the address bar, it also applies to HTML inputs and textareas.

From my understanding it stems from how Firefox renders and synchronizes frames.

I've filed a bug two months ago, but really unsure when it will get resolved.

I don't work on Firefox, but you should file bugs. I've generally had a pretty good time doing so.

I've enjoyed filing bugs too, but my first bug is about to celebrate its 10th birthday. Hopefully it will be fixed before it can legally drive a car.

While that's a long time, in 10 years you could've contributed a fix by yourself. At this point one should consider it a reminder!

While I could learn C++ or Rust in 10 years, I'm not going to do it for a bug that isn't even biting me any more. I've long since worked around it. It makes more sense for me to donate to Mozilla so they can hire someone who knows what they're doing.

I've noticed this on Windows. The new Firefox seems to be a bit more chatty to the disk. If some other process is hammering the disk then autocomplete gets really laggy. I suspect it is optimized for SSDs.

On the other hand, if the disk is idle it is blazing fast.

Reminds me of behaviors i have seen on Android for the longest time (to the point that i have effectively given up on using Firefox on Android because it slows down so easily there).
