Undesired Bounce Back with macOS Keyboard Shortcut for 'Move Window to Right Side of Screen'
In macOS you can set up a global keyboard shortcut for the Move Window to Right Side of Screen command via System Settings > Keyboard > Keyboard Shortcuts.... In most apps that support the Move Window to... commands, this will simply move the window to the desired side of the screen when the key combo is pressed.
However, in Firefox the key combo will start the animation as normal but the window will then bounce back to its original location. It's only when the command is activated via a keyboard shortcut that it does the bounce back behavior, though; the command works as intended when activated from the Window menu in the menu bar or from Option + green button in the top left of the window.
The key combo I set up was Shift + Option + Command + Right Arrow, but I've also tried a couple of different key combos and they all did the same bounce back behavior. I've tried it on machines with different versions of macOS (Sonoma beta and Ventura) with the same result. The bounce back behavior also effects the Move Window to Left Side of Screen command.

It seems like you've encountered an issue with the 'Move Window to Right Side of Screen' command in Firefox on macOS. The bounce back behavior when using the keyboard shortcut is unexpected. This could be due to a conflict with Firefox's internal settings or how the shortcut is interacting with macOS.
To help resolve this, I suggest trying a few troubleshooting steps. First, check if there are any conflicting keyboard shortcuts in Firefox or macOS System Preferences. You can also try resetting Firefox to its default settings or testing the keyboard shortcut in a new Firefox profile.
If the issue persists, it might be helpful to report this problem on the Mozilla Support Forum, providing details about your macOS version, Firefox version, and the specific keyboard shortcut you used. The community there can offer further assistance and investigate the issue.
I'm able to reproduce this as well. Any keyboard shortcut I set will result in the same bounce-back behavior.
