hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is slowing you down...

(replies on the forum seem to work again, so for the other contributors reading here, i'll paste the conversation we had via PM:)

philipp Today at 5:02 PM
when you open the windows task manager (ctrl+shift+esc) an go to the processes tab, do you see a high use in cpu-ressources by firefox.exe when this problem happens?

Question2 Today at 5:47 PM
Nope, CPU usage is usually 5-10% and i have 16 gb of ram but only using 2 gb or so when web browsing.

is this 2gb RAM usage just related to the firefox process? this seems to be rather high and cause hangs during "garbage collection" (when firefox is trying to reduce memory usage)... could you try to reset firefox in this case?

No, it's not just the firefox process. Unfortunatley ive got lots of open tabs at the moment, so i cant reset firefox.

Besides, with 16gb of memory im pretty sure firefox can handle it...

firefox for windows is a 32bit application and cannot make use of more than 2gb of ram - if the ram usage comes within the realms of this area, slow-downs and hangs are to be expected...

It doesn't use 2 gb of ram though.

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox profile folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them).

How large is your sessionstore.js file?

Are there any numbered sessionstore-##.js files in the profile folder?

If there are then you should definitely remove those as they have no purpose and force Firefox to scan the directory to find which number to use for the temporary sessionstore file when creating a new file, which happens every 15 seconds (browser.sessionstore.interval).

You can temporarily move the current sessionstore.js file to another location to see if this helps.

I just deleted two extra session store files. The current session store file is 18.7 mb large.

With a sessionstore.js file that large, you may want to consider to increase the browser.sessionstore.interval pref.

This pref determines the minimum interval between saving the current browser state to disk in sessionstore.js

  • resource:///defaults/preferences/firefox.js
// minimal interval between two save operations in milliseconds pref("browser.sessionstore.interval", 15000);

How will that help though? Seems like it would only make it easier to lose my session state in the event of a crash.

Yes, that would happen, but it does give Firefox more time to save the session data and complete other tasks.

Do you have any idea why the sessionstore.js file is no large?

Do you have a lot of tabs open with a large session history (back button) or otherwise tend to store data as session data?

Does this also happen in a New Private Window where Firefox doesn't store data to disk, but keeps it in memory?

You can also try to copy the sessionstore.js file temporarily to another location to test if it is this file that is causing it and not another cause.

Firefox 20 version and later have switched to Private Browsing mode per Window.

You can find Private Browsing in the Firefox menu button drop down and in the File menu as "New Private Window".
