For the past few months, my FTM cookies (MacUpdate, eBay, and maybe, but I can't be certain, others too) have been "disappearing" before their scheduled expiration date.

These cookies disappeared last night.

It's beyond annoying!

Is anyone else experiencing the same thing?

I suppose this may be a Safari issue, so mods, please move this if it belongs elsewhere.

More: The cookies aren't expiring early and being renewed. I'm being forced to log in anew each time it happens.

I ran into a spate of that happening a month or so back and only on the Mac, neither the IPhone or iPad appear to have encountered a similar problem. I have not encountered the issue for a while, but I have since updated to macOS 13.1 and changed my default browser from Safari to Safari Technology Preview, so I have no definitive clue to the cause. As a suggestion, you might try [ur==https://developer.apple.com/safari/technology-preview/]safari Technology Preview[/url] and see if the problem goes away.

Alternatively, having reread Jon's linked article and not been made as apprehensive about Ventura as I was the first time I read it, I may just upgrade and see how it goes.

In case I either now or eventually move to Safari Technology Preview, though, will you please explain how to go about setting things up in iCloud so I can share bookmarks et. al. between Safari and STP.

Thanks.

There is nothing to setup. STP and Safari use the same settings files, etc.

Do you remember to check the Remember Me box when you log in?

Thanks, but I decided to upgrade to Ventura rather than experiment with STP. Fingers crossed!

As an aside, how does your response jive with Wouldn't I first have to check both Safari and STP in System Settings > Internet Accounts > iCloud?

1. Safari and Safari Technology Preview use the same preference file(s), cookies, extensions, bookmarks, autofill data, password database, etc.
2. The only difference between the two is the actual executable, which includes the version of WebKit *¹ *².
3. There is no provision in Settings > Apple ID > iCloud for Safari Technology Preview *³
4. iCloud only gets involved when the settings are shared between different devices. This enables Safari & Safari Technology preview on my Mac to share the same settings, bookmarks, autofill data, and password data with Safari on my iPhone and iPad.
5. Cookies and extensions are unique to each device, regardless of what is checked in Settings > Apple ID > iCloud.

In short, then, Apple should have said

Which could imply Software Technology Preview is available on “all your devices”, which is a falsehood. Pwersonally I would have left any reference to ICloud out. It is not as if Safari Technology Preview has any more abilities in that regard than Safari does. I suspect that is a result of some overly-enthusiastic marketing speak.

I just realized that assertion may not be 100% true. If I am logged onto a website on my iPhone and bring it near my Mac, the Safari, or Safari Technology Preview, the icon on the Mac's Dock changes and I can transfer the iPhone's connection including the site logon to the Mac, simply by clicking on the modified icon. That also includes data stored in cookies. I assume the cookies are synched between the devices via Bluetooth(?), but I have no idea if they are physically copied or read remotely on the other device. I do know the two logons remain synchronized.

No luck upgrading, nor did I have much hope, because Ventura and Monterey run the same version of Safari.

I guess I'll try STP.

I installed STP, and although it has found my extensions and password database, it is not finding my cookies or bookmarks.

I hope there's a setting I've missed, because while my cookies will grow back on their own, I've got absolutely no inclination to replicate my bookmarks.

Rats! Although STP has found my extensions and password database, It has not found my cookies or bookmarks.

The cookies are no big deal, because they'll grow back eventually, but I"ve got absolutely no inclination to replicate my bookmarks.

I tried replacing STP's bookmarks plist with Safari's - shut down and restarted for good measure - but no luck....DEAL BREAKER!

Does Safari Beta sound like a viable alternative?

I have no idea why Safari Technology Preview has not picked up your bookmarks. I just searched my system using FindAnyFile and I only have one set of bookmarks for Safari and there are no separate bookmarks for Safari Technology Preview

Safari Technology Preview is in a sense a Beta, but a bit more than that. It is used to try out potential browser features to see if they are worth developing and including in a future release of the OS and Safari. The actual Safari beta is only available as part of the OS beta. (Yes, there are links to a Safari beta, but they end up re-directing to Safari Technology Preview). Safari beta issues are reported through the macOS, iOS, or iPadOS Feedback Assistant that is installed as part of the beta OS, while Safari Technology Preview Feedback is a separate system accessed from the STP Help menu.

I've got ~/Library/Safari/Bookmarks.plist, and I had ~/Library/STP/Bookmarks.plist, and as I said, even after I trashed the latter, replaced it with the former, and did a cold start, STP still reported the same bookmarks as were in the trashed file.

I have the ~/Library/Safari/Bookmarks.plist that contains all my bookmarks, but I do not have the corresponding file in ~/Library/SafariTechnologyPreview/ which is what I expected, but that doesn't explain why you have the Bookmarks.plist in both folders and I don't. To be truthul, I have used SafariTechnologyPreview off and on for years and I may have performed some step that I have long since forgotten. You might try copying the Bookmarks.plist from ~/Library/Safari to ~/Library/SafariTechnologyPreview and see if the full set of bookmarks shows up in STP.

When you trashed the Bookmarks.plist, did you also delete ~/Library/Saved Application State/com.apple.SafariTechnologyPreview.savedstate? That might account for the restored bookmarks.

I had trashed STP after moving in ~/Library/Safari/Bookmarks.plist didn't help, so I reinstalled it, and again didn't have my bookmarks or cookies. (STP didn't pick up my prefs either, but I'm not sure if it's supposed to.)

So before doing anything else, I took a look and found that ~/Library/STP/Bookmarks.plist didn't exist but ~/Library/STP/TopSites.plist did, so I moved it to the side, moved in ~/Library/Safari/Bookmarks.plist, and VOILA! (The ~/Library/STP/Bookmarks.plist I originally reported having was apparently created by me when I bookmarked FTM.)

At any rate, I've now got a usable version of STP, albeit sans cookies, which I'll recreate as I go along, and hopefully they won't disappear.

Then why don’t I have separate files for SAFARI & STP, but I have the identical bookmarks in each and if I edit a bookmark in one the change appears in the other?? I would suspect it was because of the iCloud connection, but the bookmarks don’t go away when I din’t have an internet connection.

I am still missing something, but what???

That is not the case with my installation.

Nothing more than an explanation, or perhaps just an insight, apparently.

I checked the Safari box in Apps/System Settings > AppleIDPrefPane > iCloud, and my Safari and STP bookmarks synchronized with no further ado.

I then turned off my Internet, and the two sets of bookmarks remained in sync when I added/deleted a new bookmark.

Ha! So it turns out that is on the mark, but exceptionally poorly presented.

My cookies haven't synchronized, but that's in keeping with the quote.

Case closed...except for some residual head scratching.

Getting all the way back to my OP, my cookies are still disappearing...now in the latest version of Safari Technology Preview. (The status was quo in the latest version of Safari last time I looked.)

Your situation appears to be relatively unique. Have you tried turning all Safari extensions off? Didn't you used to run the Cookies application? Could there still be remanants hanging around?

The only extensions I'm running are Roadblock and Wipr, neither of which should have anything to do with cookies.

I'm still running Cookie, but I've asked its dev about the issue a couple of times and haven't received a response, nor have any of his updates addressed it. I've now disabled Cookie to see if it accomplishes anything. (ryck is also running Cookie, and he apparently hasn't had any problems.)

The curious thing about this is that not all of my cookies disappear...only the ones that affect login.

Ah ha! I just focused and realized that it's the "Remember Me" cookies that are disappearing. (MacUpdate doesn't present me with the option, although it does remember me.)

Any thoughts on that?

I will be interested to know if there is any change in behavior since you deactivated Cookie. I would posit that the “Remember Me” cookies are simply the ones you are aware of disappearing because they are the most obvious. There could easily be any number of cookies being deleted and later being recreated, unless you actively audit all of your cookies at the beginning and ending of each on-line session. It is easy enough to deactivate and activate Safari Extensions, that even though neither Roadblock or WIPR should have any effect, it might be worth deactivating them, one at a time, to see if either has any effect.

You're correct on both counts....no issues here.

It may be because you're running a "legacy" version of the OS, and my problems began in Monterey.

Update: I quit Cookie for a full month, and my “Remember Me” cookies remained in place for their prescribed 30 day life. Then, 10 days after I restarted it, my FTM cookies disappeared along with my PayPal and Ally Bank cookies (which have also been problematic, but, I think, unmentioned).

I'm going to let Cookie run another cycle before contacting its dev who hasn't been very responsive in quite a while.

I believe you're correct about other cookies disappearing, and I've tried auditing my PayPal and Ally cookies, but it's too complicated a job, so the best I can say is that I'm almost certain that some other cookies do disappear, but I can't pin down which ones.

If you're really into frustration, try following MacUpdate cookies which, for some bizarre reason, expire weekly.

Great time of year to talk about cookie problems. Mine show up on the bathroom scale.

Update: My disappearing cookies are for Chase Bank and FTM, but there may be others that I've never run into. The other sites with which I had a problem turned out to be victims of cache clearing.

I've now emailed Cookie's dev 3 times and not received a response - I guess it's a selfish reaction to my having called him out...story upon request.

At any rate, I've now trashed Cookie. (I guess I'll give it another try after a looong hiatus.)

As it was back in October, when your issue first surfaced, I continue not to have the problem. On my machine, all relevant pieces of software (OS Monterey, Safari, Cookie) have since been updated.... but no change.

Bizarre!

Cookies is only one of the ways Remember me can be implemented, and I know that FTM cookies have a relatively short (30 day) expiration date. Although I have no experience with Chase, I do have on-line accounts with multiple financial institutions and while all of them at one time did Remember me, I just made a quick check, and none of them, currently Remember me. While I haven't paid any particular attention to whether or not those sites remembered me, I BELIEVE that change has taken place this year and corresponds to significant site upgrades and increased site security arrangements including required two-factor authentication.

My point being, the change may be the result of financial institutions finally getting serious about site security and have nothing whatsoever to do with Safari or Cookie?

First, I'll note that the last time I looked, MacUpdate's cookies expired after only (a ridiculous) 7 days, and if I remember correctly, you posted a while back that there's been a recent push for shorter cookie lives than have historically been used.

I don't think my issue's got anything to do with strengthened security, though, because FTM has made no changes other than shortening the lives of its cookies (nor has ryck, who's still running Cookie, run into my issue).

Of the websites at which I've had problems, my FTM and PayPal problems go away when Cookie goes away, and my Chase Bank problem occurs only when I clear cache.

Here's a four month history of my FTM cookies, and as you can see there's absolutely no rhyme or reason to their disappearance.

I wonder if many of the sites that don't remember you are simply the result of your not having visited them for so long that their cookies expired?
