I do NOT want firefox to load 200 MB EVERY time i start it JUST because it wants to load the last pages that were opened. How do I disable this?

more options

I usually close firefox through the windows taskmanager with the "end process" command because it always becomes unresponsive sooner or later (i think due to website scripts that stop responding).

Anyway when i open it afterwards i have to wait like 1-2 min while it loads and loads and loads (150-250 MB ram) all the sites that were opened in the previous session. I do NOT want this i want to disable this horrible feature but currently that is not an option. Or is it ? How can I disable it?

I want my firefox to start up quickly without loading previous sessions no matter how it was closed.

See:


Set the Integer pref browser.sessionstore.max_resumed_crashes to 0 on the about:config page to get the about:sessionrestore page immediately with the first restart after a crash has occurred or the Task Manager was used to close Firefox.

im asking how to disable that not how to enable it ... in my "when firefox starts:" box ive chosen "show my home page" but it still loads stuff from last time because i've closed the program by ending the process in taskman. ... which i explained in the question but w/e thanks anyway

Set Firefox to open with a home page instead of opening the tabs from last time. Do that from Options > General.

Hi shaolinsoccer86, if you set browser.sessionstore.max_resumed_crashes to 0 as cor-el recommended, rather than loading tabs automatically after a crash, Firefox will present a list of windows/tabs and ask you whether you want to selectively restore particular ones, or just start a new session. Although you could completely eliminate this option, Murphy's Law counsels in favor of preserving your choice. ;-)

thank you both. i set it to 0 and it seems my problem is gone :)

That still leaves the question of what is bogging down your Firefox sessions, but we could save that for a new thread. (If you do start a new thread on that, please try the new Troubleshooting add-on pushed to you during the question flow to conveniently list all your extensions and certain modified settings along with your post.)

i actually didn't notice before but even with the setting set to 0 it still loads all the stuff - the only difference seems to be that it puts it in a neat little list instead of actually opening additional tabs etc. -_- (which is better than nothing)

i only have adblock and memory fox as addons but i got those after the problems started.

usually i stream videos while surfing and running many programs in the background and sometimes i get firefox's error message about website scripts becoming unresponsive - that's usually when firefox itself becomes unresponsive itself.

ill try more troubleshooting guides etc later this week and get back to you

There also is the more extreme preference that might completely turn off post-crash restoration: browser.sessionstore.resume_from_crash. I haven't tested it myself.
