Disabling 'Show animations in Windows' changes the way text is shown on some websites.
When I turn off the windows animations in Windows 10 the font on Twitter.com changes somewhat. I believe it is altering the character spacing/scaling.
I have not had this behavior on other browsers (Brave, Edge, Chrome & OperaGX tested). I have not noticed this on other websites, but I also haven't really looked.
Windows version 22H2 (OS Build 19045.4291) Firefox version 124.0.2
Images provided are with them off, then on
Steps to recreate 1. Load a tweet (tweet in the images: https://twitter.com/FedeItaliano76/status/1779855670432408011) 2. Turn off window animations (settings->display->show animations in windows->Off) 3. Reload the Tweet
This is not a critical issue for me, but I think it's worth mentioning

Another way to disable animations is to create ui.prefersReducedMotion (Number) with value 1 in about:config.
Does it still happen in Troubleshoot Mode?
You can right-click and select "Inspect" to open the built-in Inspector with this element selected.

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Fonts tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website. If the Fonts tab is hidden, click the Down arrow at the right end.
Via inspect element: when the windows animations are off it's using Times New Roman on the 'quote tweets' text and Segoe UI on the main tweet text, but with the animations on it's using 'TwitterChirp'. This persists in Troubleshoot Mode
I have the Control Panel For Twitter extension which is likely causing the Quote Tweets box to show a different font from the rest. I have disable this extension and it persists
I've also updated to Firefox 125.0.2
The animations I want disabled on Windows but enabled on Firefox for smooth scrolling
It always uses Noto Sans for me, regardless of the animation setting.
You can enable animations by creating ui.prefersReducedMotion (Number) with value 0 in about:config.
