Very useful for me. Unfortunately I have the same problem (like Michael or Deadmarsh) for Firefox about 109 and up on Windows 10.

Has been perfect, but as of 01/2023 negative pixels for positioning no longer seem to work and there are stripes at the right and bottom of the browser I can't get rid of without manual window sizea adjustment. I mostly position the browser to the right side of the screen and when on the left slighly out of screen to the left.

I have an issue. I have saved more than 1 preset, but when I click the Resizer icon, only the 1st preset is activated. How do I make use of the other presets? Thank you.

EDIT: I just noticed your release notes, which seems to be the only place that explains how to activate the other presets.

Ultra simple and action in one clic! Perfect in many cases. But the old school icon... ;)

Very simple app automatic increase text files and windows, it works!
