How can I close the current tab in Firefox v 17.0.1?

Posted

I have used Firefox for years and have always used Tabs instead of opening new windows. I have always been able to click the little "X" on the right side of the tab to close it. I am finding now that I cannot close the current tab by doing this. I have to click on another open tab and then click on the other tab I wanted to close.

I have looked through the Options many times trying to see if there is a setting I need to change, but have not found anything.

Is it possible in this version of Firefox (v17.0.1) to close the current tab?

Chosen solution

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do not click the Reset button on the Safe mode start window or otherwise make changes.

Yes it is possible to close the current if you don't have any activity to do in Firefox. It is tantamount in closing your Firefox browser. Even in IE9 and Chrome, current tab can't be close unless you will open another tab or clicking the red X at the right section of your browser if there is only 1 tab open which is equivalent in closing your browser.

Helpful Reply

I started Firefox in SAFE MODE and the problem went away. I checked for updates and all were up to date. I then restarted Firefox and it worked fine. Since I didn't really do anything, I am curious as to why it is now working as expected. I am glad, but still curious.

Thank you.
