I have lost all of my bookmarks, bookmark tool bar after Firefox's last update. I have spent the last day trying to recover what has been lost but I am having no luck in getting everything back in place. I have tirelessly gone over all your possible remedies and get no results. I can't even send a message to Mozilla through their help messaging system. My only recourse appears to start using another web browser. If I can't talk to someone who can help guide me through a mess I did not cause, then I am forced to find another company that is responsive to my problems. Call me at [edited] or write me at [edited] if you want to keep me as a user of your service. Regards Mark Hannah

I found a folder on my desktop entitled Old Firefox data. It contains a folder entitled 3h0lsis5.default-release. It's almost 900 MB. Do I need this folder? Or can I delete it? Thanks in advance.

with the new function of Tab Groups i was wondering if it is possible, or can be added in the future, to sync existing Tab Groups to all or specific devices in order to access created groups on my private Macbook to my work Windows Firefox.

thanx for any reply

I have tried all of the recommended ideas in the articles about reloading bookmarks and nothing has worked.

I have the following problem and situation: I reinstalled Windows and did not write down the password for the Firefox account, and after logging in I restored the password, but it feels like my account has been re-registered, all saved tabs and passwords do not appear, but at the same time there is only one email that was used for synchronization and logging into the Firefox account. this email you can also contact through it: [email address]

Hello,

I accidentally disliked a thought-provoking story which involved the couple who died in the Lisbon funicular crash (as of Saturday 6th September 2025), which I think was addressed by The Independent.

Is it possible to reverse the dislike? The story does not seem to appear again, at least from what I have seen. Although the dislike was accidental, I felt that having the story disliked would indicate I would not be interested in thought-provoking stories about those who have died, even though these stories should be important to show.

I am definitely not interested in bells and whistles. Just want basic program. The new update ate my current settings and book marks. Did not create a backfile with my profile. Your help process sucks big time. Do you even do beta testing before you send them out?

Добрый день! Я создавал аккаунты через расширение мульти-аккаунт в браузере и сейчас все аккаунты удалились с браузера. Есть какая-то возможность вернуть аккаунты? Их было очень много и они очень важны
