User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0
Steps to reproduce:
I snapped the Firefox window to one side of the monitor, so that it occupied half of the screen. No horizontal scrollbar appeared. It was impossible to scroll the window horizontally. Window had to be maximized to see it all.
Actual results:
I snapped the Firefox window to one side of the monitor, so that it occupied half of the screen. No horizontal scrollbar appeared. It was impossible to scroll the window horizontally. Window had to be maximized to see it all.
Expected results:
Horizontal scrollbar should have appeared at the bottom of the Firefox window when it was snapped to one side of the monitor.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Win32' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Did this occur more than once? Is there a particular website that reproduces this issue? What version of Windows and Firefox are you running?

Problem occurs on al websites. I'm using FF 100. This bug is new to FF100. No such problem in previous versions.

Could you please use mozregression to identify exactly what code change may have introduced this? There is a video at the top of this page that explains how to run the tool: https://mozilla.github.io/mozregression/quickstart.html
Sorry, I don't work for Mozilla. You do.

This isn't an issue that reproduces for all users, and I certainly wasn't able to reproduce. I suggested a path for you to ensure that we can fix this issue for affected users such as yourself.
This scrollbar behavior was wrongly reported as a bug. A change in Firefox v.100 conflicted with an existing CSS customization. When I removed the customization, scrollbar behavior returned to normal. The appearance of the scrollbars no longer can be controlled using CSS. Just one more step backward.
