Description

Is the feature relevant to the Firefox PDF Viewer?

Yes

Feature description

What if there was a way to set an exact value to the sliders, such as the text size slider?
<input type="range" id="editorFreeTextFontSize" class="editorParamsSlider" value="10" min="5" max="100" step="1" tabindex="0">

There's a way to do this in the console, pasting:
const slider = document.getElementById('editorFreeTextFontSize'); slider.value = 25; slider.dispatchEvent(new Event('input', { bubbles: true }));

But what about an option in the contextMenu?
Unfortunately I can't do this with an Web Extension.

Research direction

Start by locating the input with id editorFreeTextFontSize and the existing contextMenu handling in the Firefox PDF Viewer. Trace how slider input events update the text size, then determine how an exact-value option could use that path. Done means the context menu can set an exact slider value and the viewer reflects it.
