Steps to reproduce:

  • set about:config option browser.tabs.tabMinWidth to 32
  • open many tabs, so that just 1 character is visible for each tab
  • move cursor to X button for active tab

Actual results:

X close button is moved a bit right, off the previous position and a bit off the tab area, so that X button is "jumping" between 2 positions, when moving a cursor.

Expected results:

X close button should stay at the same place.

It works good in Chrome and Edge, even if the tab width is the same, or even thinner.

Firefox 120.0 (64-bit), Windows 10 22H2 64-bit.

Tested also with the latest nightly, default settings, same result: 122.0a1 (2023-11-21) (64-bit)

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

Component: Untriaged → Tabbed Browser

I've reproduced this issue in the latest Nightly 122.0a1 (2023-11-23) and Firefox 120.0 on Windows 10 x64.
Setting this as NEW and waiting for the developer's opinion about it.
I didn't manage to find the possible culprit here due tot the following error:
