Is there a bug for this ?

The tab bar is still really slow to scroll horizontally - does anyone know if there is a bug raised on this?

Yeah, it's already known. I've been told uMatrix works though and the functionality is similar. It may be worth giving it a shot until it's fixed.

Filed a bug for more compact buttons https://bugzilla.mozilla.org/show_bug.cgi?id=1388457

FoxClocks is dead from today. Still showing date and time on a toolbar but unfortunately not updating data after browser launched, so basically dead.

In the meantime I managed to get my userstyle working, but it required a bit of dirty hacking. Will see how long it lasts.

That normally means that something failed to build or failed to work. Which is a good thing. :-)

Why is the font different in Nightly? I mean, Youtube video titles should be bold as in every other browser.

There are some cases when a font face is like a completely different.

I'm not sure, but that might just be a difference in the kind of cleartype rendering used. IIRC Firefox on Windows still uses the style where letters are rendered sharply at the expense of kerning quality, whereas Chrome switched to the Linux style where perfect kerning takes precedence over font sharpness.

If I recall correctly, setting gfx.font_rendering.cleartype_params.rendering_mode to 5 in about:config should give you the default style for DirectWrite that prioritizes kerning quality. It's been a long time though, 5 might not be the right value.

Of course, it could also be that Firefox is getting subpixel anti-aliasing where Chrome is falling back to grayscale, I haven't looked into these things enough to tell which is which.

There are some cases when a font face is like a completely different.


Hmm... same regardless of Stylo being enabled or not. Weird thing is in both Edge and Firefox it's being computed as font-weight 500 which isn't bold but it's bold in Edge.

Yes, those are definitely different fonts. Firefox is using a serif font, Chrome and Edge are using a sans serif font there. I don't know why, do you have any custom font settings for either browser?
