Session Restore

I am using Ten Four Fox on an elderly i-Mac G5 running Tiger. A problem I have is with websites that automatically try to download ads, videos and scrips - many of which will not run properly and just slow down my computer. I have the ad blocker on, but it does not stop everything. Sometimes Ten Four Fox will just hang in an endless spinning beachball and the only way out is to force quit or reboot. Now here is my gripe - when restarting Ten Four Fox it goes to 'Session Restore' and tries to download the dodgy script again, causing the same problems. Is there a way that session restore can be switched off please so that a clean reboot is possible?

    Yes, there is. Type about:config in the URL address bar and navigate to browser.sessionstore.resume_from_crash, which must be set to FALSE.

    I recommend installing uBlock in addition to the built-in Basic Adblocker and using filter lists that deal with resource abuse and annoyances (in addition to the regular EasyList etc.) :

    Thanks Chris, that's brilliant! I have changed it to 'False' so will see what happens next time I need to force quit.

    Will also try uBlock as you suggest. An increasing problem I find with websites is 'ad blocker blockers' preventing any form of access without disabling protection.

    Conveniently, there's an „Adblock Warning Removal List“ available in uBlock, which (in most cases) takes care of this problem :-)
