What is wrong with digits?

What is wrong with digits? This is awful.

Zoom: 10x

Font = Fira Sans.
Size = 10

I guess it's a hinting problem. Are you using otf files or ttf files? I remember ttf files render better on Windows, while otf have some uneven numbers as shown in your picture. But it was from an old version though. Not sure how the latest one render on PC.

I use Manjaro Linux. And I downloaded latest zip archive of this repo and unpacked it in my ~/.fonts folder.

Are you going to do something with "bouncing" digits?

Font = Fira Sans
Size = 11
Face = Regular

antialias = true
hinting = true
autohint = false
hintstyle = hintfull

[atheistray]

Can you check whether you're using the otf files or ttf files? This repo has both of them. TTF files are under the WEB directory. If you're using the otf version, try the ttf version.

Soviet Man, we’re not going to change automatic TT hinting settings of Fira Sans for the final version, 4.3.

But Fira GO will have basic manual TT Hinting. Your issue should be solved by that.

Wow! What’s Fira Go?

[carrois]

FiraGO is the new branch of Fira Sans.
We added multiple script support (Arabic, Deva, Georgian, Hebrew, Thai) and, as said, basic manual TT Hinting.
Further developments will be based on FiraGO source files, not Fira Sans.
Release very soon! :-)

@atheistray, yes, you were right. Using TTF version fixes the problem, although I use Manjaro Linux, not Windows.
But why is that? I heard OTF format is superior than TTF.

@carrois, new font? Very interesting!

1. What faces are you going to implement within new font? Sans? Serif? Mono? I hope you will consider all the disadvantages of Fira Sans family.
2. When will you release it?

What faces are you going to implement within new font? Sans? Serif? Mono? I hope you will consider all the disadvantages of Fira Sans family.

Only the normal-width Sans/Italic for now. But it is definitely a goal to go for more widths, styles, language support etc.
Funding is welcome, though ;)

When will you release it?

Very soon. We’re currently finalizing our new company/website/shop: bboxtype.com.

FWIW, the problems shown here are probably from FreeType's autohinter being very strict about number glyphs needing to align to the same font unit height to be properly hinted. As in, the flat tops and round tops in 0123456789 need to be on the same height each. Seems fine in Fira Go from what I can see on a quick scan.
