- Visual Notes によるレビュー (6日前)5 段階中 1 の評価Doesn't work with Firefox 87.0 on macOS Big Sur 11.2.3. The add-on states that it has resized an image, but there is no way to save the resized version of the image.

No matter the actual window size, if whether maximized or not, this add-on always detects and displays a window size of 632x119, and offers to use that – and only that size for a new resolution to save. Of course, the result is an unusably minute letter box size browser window without any page content visible.
I suspect the add-on's inability to detect the correct window sizes stems from the browser's protection against fingerprinting. However, other similar add-ons don't have this problem with identical Firefox settings, so this is a no-go for me with this WindowSizer add-on.
The setting of the window size itself might work, though. I didn't really take the time to measure whether the resulting window really had the 632x119 pixels. ;)
