this email wanted to know if I was satisfied - how could I be, when the problem wasn't solved?

next I asked another question {Which I can't see in my Emails} which netted me this reply,

I am as much a believer in security as the next person but I don't understand what is going on,

I have had no response to my original ticket, which I beleive was number 305857 which I can no longer find any refernce to in my account, and I still have a completely blank Library! and I can't even make any new bookmarks!

Plaes help, Yours sincerely, Ms Jacq Felis (AKA Kaelkitty).

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

個人的にFirefoxの過去のアクセス履歴が欲しいため、毎日places.sqliteのバックアップを取得していました。 先日、バージョン154.0になった時点で、突然それまで利用していたアクセス履歴やブックマークが使えなくなり、バックアップしていたplaces.sqliteファイルをコピーしても同様の現象が起こってしまいます。

詳しく調べたところ、どうもバージョン154からplaces.sqliteに格納されているテーブルの構造が変わっているようで、アクセス履歴などが消えた理由もそこにありそうです。

今後も過去のアクセス履歴は利用したいため、直前のバージョンのplaces.sqliteを新しいバージョンに移行する具体的な方法について、もしご存じの方がいらっしゃったらご教示お願いします。 (sqlite managerなどツールを使ってのインポート/エクスポートは既に試しております)

I cannot figure out how to add my favorite things to the toolbar. The toolbar doesn't even show up at the top of my page. I just get a string of random bookmark names under the address bar with the Other bookmarks folder at the end. I can't even get rid of "Finish Setup" which is the last one shown. How do I do find where the toolbar is hidden and get it to show? Once I do find it, how can I add my favorite items to the toolbar? I even had ask a question online to find out how to restore my most recent bookmark which was backed up in the documents folder on my computer. Any suggestions would be very helpful. I don't like the way Mozilla Firefox looks now. It isn't as easy to use. I have included what the top of page looks like now. I am sorry I didn't think to keep one of how it used to be.
