In options, checking a new tab instead of the default a new window. After shutdown & restart FireFox returns to the w/no check mark. Can I save the check mark?


After a computer restart, Firefox always defaults in Options, Tabs, 'Open new windows on a new Tab' unchecked. After checking the box Firefox will then open new windows in a tab instead of a new window, However after a shutdown of the computer the check mark is gone and must be rechecked. Is there a way for Firefox to remember the check mark when the program is restarted?

hello gearjam, first of all it appears, that you're using an outdated version of firefox with various known security vulnerabilities - please Update Firefox to the latest version as soon as possible to stay safe while you browse the web.

regarding the problem you're observing, please make sure that no extension in firefox > addons > extension with the functionality to change tab settings is interfering here - or if this is not the case, go through the steps described in How to fix preferences that won't save.
