In your address bar type about:cache in the session Disk cache device you can see the path!

You can see the location of the Firefox disk cache on the about:cache page.

• /Users/<user>/Library/Caches/Firefox/Profiles/<profile>/Cache

When data is streamed then Firefox may not store pages in the disk cache, so you may be out of luck.

many thanks cor-el --- you really are a star!

related question:

I cannot find setting clear history when Firefox closes

i am sure it was under preferences. but i cannot find it. can u pls tell me where it is. thankyou

To see all History and Cookie settings, choose:

• Firefox > Preferences > Privacy > Firefox will: "Use custom settings for history"

• https://support.mozilla.org/kb/Options+window+-+Privacy+panel
• https://support.mozilla.org/kb/Clear+Recent+History

The "Use custom settings for history" selection allows to see the current history and cookie settings, but selecting this doesn't make any changes to history and cookie settings.
Firefox shows "Use custom settings for history" as an indication that at least one of the history and cookie settings is not the default to make you aware that changes were made.
If all History settings are default then the custom settings are hidden and you see "Firefox will: (Never) Remember History".

arrh .. it was hidden as you say under.""Firefox will: (Never) Remember History". " many thanks again!

You're welcome

much bigger problem now Firefox will not open back up

what I did was dl the 2 addons. they required a restart I changed the setting that I could not find unchecking cache

--- and maybe this is problem I said apply update to the advance bookmark (no 2) you suggested I use (that was another question a month back I asked). bookmark2 update

--- now ff won't open

-- so I rebooted entire MacBook (maverick osx, latest 10. 9.2)

and started in safe mode by holding Option key down

and it's been spinning now for at least 30min

I bet it's those bookmarks

as FYI since loading that adv bookmark addon a month ago ff crashes between 3-10 times a day. but I need that addon so much I just put up with it

u have addon session manager, so I can easily resume after those crashes

BUT now.... very very very bad ff won't open

help pls.

I wait for cor-el reply as last time I hot in a pickle I got bad advice that cost me 1 day of lost time repairing what got lost

thx

hi cor-el FF still wont open. even in safe mode. I am using chrome now until you have time to lmk what to do.

this is the specific addon culprit, that i updated just before restarting. just posted the review https://addons.mozilla.org/en-US/firefox/addon/add-bookmark-here-2/reviews/#review-edit-form

before restart 1 i installed the 2 cache viewer you suggested above 2 changed the cache clear security preference setting 3 updated to lastest version of addon, addbookmar here2

i have heaps and heaps of addons and 100s of bookmarks. maybe over 1000 even.

so await your guidance thanks

I'm not sure if that extension would cause this issue and that maybe something else went wrong if starting in Safe Mode doesn't work.

Did you try to reboot the computer?
