Firefox gemenskapsforum

I am using Firefox (156.01) on a MacBook Pro (2023, M2 Mac Pro, Tahoe 26.7).

In Privacy and Security settings, I have checked the box to clear history and site data on closing. History is clearing, but site data is not. I can manually clear history and site data by going to the settings when I reopen it.

I noticed this issue about two weeks ago (not sure when it started). I have closed Firefox multiple times, restarted my computer multiple times, even updated my OS during this time, but the problem is consistent.

If I go to Clear Data for Specific Sites, I am also noticing that cache size is considerably higher than the sites listed (e.g., it might list 4 sites with a total of like 2MB but the cache size might be 30MB).

Do you have any suggestions for what might be happening and what fixes I might try?

Since FF 09/15/26 update manage cookies and data sites no longer will delete items. I click the 'save changes'. and that's it. All the cookies and data are still there. Hopefully a fix will be soon?

For some reason, everytime i close firefox, every website just forgets that ive been on their website before and needs me to sign-in again, even when ive clicked "keep me signed in"

In the past couple of weeks (say Sept 2026), Firefox has started signing me out of everything when it closes or updates even though 'clear browsing data' is UNchecked. What else can I do to stop this?

I want to clear the cache on this laptop that has been in storage for months, but I can't get the instructions question lines to respond when I check the boxes ??? What am i missing?

It seems the default for allowing sites to store data locally is backwards (for privacy).

You should be able to set the DEFAULT to "Allow all sites to store data locally FOR THE SESSION ONLY," and then type in the sites that you would like to allow to store data locally for more than one session (or block entirely).

Is there a way to do this? There are not many sites I would like to allow permanent local data storage, so it wouldn't be such a terrible chore to type in their URLs. The opposite is true for sites I would want to allow ONLY FOR the one SESSION - that is a HUGE chore. This appears to be a privacy & security oversight - can you fix this?

I usually have checked the option for clearing cookies and site data every time I close Firefox. However there is an exception list where I add sites I visit often and I prefer to keep its browsing data. This list of exceptions seems to be ignored. The sites I have in the list lose all their browsing data.

The only solution I have found so far is not check the option to clear browsing data.

I remember this function stopped working correctly right after I decided to wipe all browsing data manually.

When I select Photos from menu (top right bars), I get Google message that there is a problem with my cookie settings and I need to enable them. I haven't changed them.

Warum muss ich immer wieder die Surfdaten löschen damit ich die Seite meines Routers öffnen kann ? Nur dann funktioniert eigenartiger Weise mein Passwort. Es ist die Seite:http://192.168.8.1/#/home zu meinem Huawei B636 Anmeldung. Mein Firefox ist auf aktuellem Stand. Bitte um Info bzw. Abhilfe
