How to make old Firefox cookies function in a newer Firefox version?
Hey everyone,
I’m trying to import my old cookies.sqlite file from a 2015 Mozilla Firefox version into the latest Firefox version. According to Google, it should work even though it’s quite old. But when I try to dump it into the profiles folder, none of the cookies appear in the list when I manage them or switch to Storage. I’m not sure where they should be saved—maybe I’m placing them incorrectly. I’ve pasted them into a location like Users/Owner/AppData/Roaming/Mozilla/Firefox/Profiles, but they don’t show up. There are several files named cookie in that profile, possibly some interfering. If you can help, it would be really appreciated!
I am proposing an alternative method.
This is mainly due to the necessity of reviving 10 year old cookies initially.
It might become outdated or pose potential risks in some cases.
Avoid importing the older cookies. Who can predict all the changes that could occur?
You are probably agreeing to many terms you may not wish to accept.
Gradually, visit the sites you currently need and restore cookies or configurations as needed, respecting any restrictions you set.
Please review the terms carefully before proceeding.
Thank you for the clarification. I understand the situation and have a valid reason for needing the old cookie file, which is approximately 2 MB. Please let me know if you need assistance with that.
Also think about the possibility of having replaced the necessary cookies file(s).
I would likely follow this approach. Set up a VM, gather all necessary offline installers from the past decade, disable networking on the VM. Install the Firefox version compatible with those cookies, restore your profile, go through updates step by step, and run each one until everything is current. Checkpoints will help you revert if needed. It’s surprising how old my Firefox profile is—some restores and conversions have been required, especially since data from 2012 still exists.
The cookies.sqlite file is just 2 MB, do you believe it contains anything, might it be empty? Can we verify this?
Finding a suitable version of Firefox for older systems can be challenging, as those from 2015 are no longer supported.
Individual cookies are very simple.
2MB can easily fit a LOT.
However, they do have an expiration date.
After more than 10 years, it's unlikely the original sites would still understand them.
I am still puzzled about why these old cookies are reincarnating...
Would it not be better to just visit the site and restore the cookies?
Assuming the website is still active and the cookies remain identifiable.
For an older version of Firefox, many changes have occurred. I wouldn’t be confident about any Windows update.
I do my best to prevent cookies from appearing. I’ve never had to go back and fix old ones.
Can you share more details about what’s needed?
