Since updating to Firefox 155, in the history side panel window at the base, I am now getting the attached message which I have never seen before. If I close the box my Firefox screen goes completely blank. Anyone experienced similar ? Apparently hovering on the link supposedly goes to chrome://browser/content/browser.xhtml#, but apparently it goes to accounts,firefox.com. uploaded the image to AI and got no viable answer. I never want to setup sync. I also notice a similar message at the base of the bookmarks side panel.

I don't see such a message in the Side Panel, so I don't know if this will help or not, but try setting the following about:config pref. to false (at least it helps to get rid of such sign-in/sync items in the AppMenu & Bookmarksmenu).
identity.fxaccounts.enabled
(Latest Firefox released for Windows)
If that doesn't get rid of it, the other place I would check is about:studies (just in case your installation of FF has been selected for some kind of experimental feature).

just as an aside: the hover link you see in the message, normally opens a kind of blank replica of your current browser (although trying to interact with it nowadays, just seems to crash FF), so I can't understand its purpose in that message.

I see on your screenshot Ctrl+shift+H but do you get the same issue with Ctrl+H

I see a similar thing if I click on the hamburger icon (3 horizontal lines) at top right: -

In answer to wiganken, Ctrl+H produces a trunctuated sign in message

However changing identity.fxaccounts.enabled to false as das 10 suggested does remove all the sign-in/sync messages that I was getting, including in the picture of this posting today. I am not participating in anything in about:studies.
Thank you

Yes I see that at the bottom of History too. Once I had clicked on the X at the top right of that box and it went away, never to be seen again.

    UPDATE - 11 April 2026: due to lid hinges starting to break up this laptop has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

    I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.

    Info for 2021-2026:
    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

Thank you.

That gets rid of the message I posted about here.

For now, at least.

Edit: I just saw your reply in that thread. Thanks again.
