Font rendering on a specific website

more options

Hello,

I have a trouble with font rendering on one specific website - https://www.checkpoint.com.

Text on this site looks quite ugly (see font01.png).

But if I open "Web Developer" -> "Inspector" -> "Fonts" -> "All fonts on page", then I can see the text renderred correctly in the preview field (see font02.png).

So text uses "DIN WXX Regular" font, but I do not understand, why Firefox cannot render it on the web page in the same manner as in the Developer tools?

Any clue how to fix it?

Browser: Firefox 68.2.0esr (64-bit) OS: Debian Bullseye

Thanks Zbynek

Hi Zbynek,

Apologies for the inconvenience. I check the website myself and it looks fine (I'm using Firefox 71 in Mac). Maybe this could do the trick?

Hi,

I belive that in every Firefox with default browser/system font settings it will look fine. But I have some system font customizations, so that could be the reason. Also I have another Debian with the same customizations (but older distro version) and the same Firefox version, where it works fine. But I don't know, why Firefox behaves differently.

gfx.text.disable-aa completely disables Anti-Aliasing, so I have the ugly font on all web sites (and no change for https://www.checkpoint.com). So the question might be how to enable Anti-Aliasing for https://www.checkpoint.com while any other pages are Anti-Aliased fine?

Thanks Zbynek

There are may be some relations between Anti-Aliasing with computer's graphic rendering services. Not sure, just an opinion.

You may have accidentally zoomed web page(s). Reset the page zoom on pages that cause problems.

  • View -> Zoom -> Reset (Ctrl+0/Command+0 (zero))

Hi, zoom is ok, that's not the issue.

Can you make it look better if you adjust the font-size setting in the Fonts tab or zoom the page.

No change.

I have tried to copy Firefox profile from the other PC (where fonts are ok) and it did not help. Based on this I guess that any change in "about:config" won't help.

So I have a few ideas what difference could be in the game: - Debian version (8 vs. 11) - installed (font) packages - hardware

Both PCs use Xfce environment and https://www.checkpoint.com looks fine in Chromium browser.

I would assume that this is more a matter of GTK font settings in Linux that Firefox get from the OS about rendering and anti-aliasing (subpixel).

Is there any developer forum/list, where somebody can help me to debug it?

So I can confirm that it brakes when upgrading from Debian 9 to 10.

Nothing to do with Firefox version.
