Tab is too far left and unreachable

Hi. This is more of a bug report.

In Firefox, I can get a tab almost off screen to the left, with a blank space next to it, and other tabs. The only part then still reachable is half of the close button.

The way I get this is as follows:

Open Firefox. Open a second and third tab. Reduce the size of the browser to about half the screen. Drag the first tab outside the browser, so it will open as a second standalone browser window on the other half of the screen.

The second tab on the first browser window (now the first tab) will then be this weird tab too far left.

The fix is to click the half visible remains of the close button of the weird tab. It will disappear. But this isn't an option if that tab actually is in use. The only way to get back to it after using another tab is CTRL + SHIFT + TAB-ing.

I hope this gets fixed soon. I've attached a screenshot of the top of this very page with said weird tab next to it.

Did you try if you can reach the first tabs via Ctrl 1-8?


Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: "3-bar" menu button or Tools > Add-ons > Appearance
  • Do NOT click the "Refresh Firefox" button on the Safe Mode start window

No, and that's a good shortcut to know.

I've done some testing and it seems Tab Mix Plus is the culprit. I didn't even think to check.

I'll raise the issue with them. Thanks.
