Question Getting old Firefox cookies to work with new Firefox version ?

[DarthGizmo]

Hey everyone,

I have my old cookies.sqlite file from a 2015 version of Mozilla Firefox that I want to import into my latest version of Firefox.

According to google, I should be able to do this, even though it is very old.

However, when I dump it into the profiles folder, none of these cookies are showing up on the list when I click Manage Cookies, or hit F12 and go to Storage, I don't see them.

I assume the list of old cookies should be listed somewhere if I successfully did this, maybe I am not putting them in the right place, I am pasting into:

Users/Owner/AppData/Roaming/Mozilla/Firefox/Profiles and them put them into Default where the cookies.sqlite file is.

There are multiple files in that Profile file with the name cookie, maybe some are interferring, I don't know.

If you can help, I would be grateful!

I am going to suggest a different approach.

One reason being the need to restore 10 year old cookies to begin with.,...

Likely obsolete and/or may prove risky one way or another.

Do not import the old cookies. Who knows what all might get changed as a result. Most likely you will be implicitly agreeing to many things that you do not want to agree to.

Over time simply go to the currently desired/required websites and reinstate the cookies/cookie configurations as necessary and with what ever limits you currently wish to impose.

Carefullly read the terms etc. beforehand.

Just my thoughts on the matter.

Thanks for the thoughts, but I really do have a good reason for needing an old cookie for a certain website, and then I can delete them.

The cookies.sqlite file I'm trying to load is about 2 MB, I'm not sure if it still works, please help me if you can.

Last time I checked, cookies do expire.

Also consider that you may have overwritten the required cookies file(s).

I would probably do it this way. Create a vm, download all of the required offline installers from the last 10 years, remove the networking on the VM. Then install the version of firefox that those cookies work with, restore your profile, step through the version updates, and run them one by one, until the system is up to date. Checkpoints \ snapshots are your friend here, that way you can easily roll back in case one of the versions causes an issue. Now you got me thinking, I believe my current firefox profile is like 13 years old. I've had to do some restores and conversions, but there is data that dates back to like 2012, that's kind of crazy.

The cookies.sqlite file is only 2 MB, do you think there is anything in it, could it possibly be empty? Is there a way to check?

Not sure how I install a version of Firefox that old, I don't think those old versions from 2015 are available.

Individual cookies are trivially small.
2MB could hold a LOT.

But they DO expire.
10+ years old, unlikely the original websites would still recognize them.

 

[DarthGizmo]

Maybe yes, maybe no. The cookie I need might still work.

So are you guys saying if I just got an old enough version of Firefox, it could be compatible?

Again, I don't know how to get a version from 2015, not sure how it works with Windows 11 either.

I am still unsure about the reason for reincarnating old cookies....

Why not simply go to the website and reinstate the cookies?

Premise being that the website continues to exist and that the cookies are (as above) recognizable.

As for and older version (10 years) of Firefox - much has changed. I would not be optimistic with respect to any given version of Windows.

I do all that I can to keep cookies out. And have never encountered the need to go back and recover old cookies.

Are you able to provide more information about the requirement?
