Hi Antonio,

Thank you for providing the detailed info! Are you sure there is no Manage Bookmarks option? It should be the last one, at the bottom of the menu. Alternatively, you should be able to open the same window by:

• Pressing Ctrl+Shift+O
• Pressing Alt to restore the menu bar and then selecting Bookmarks -> Manage Bookmarks
• Right-clicking your Bookmarks toolbar and selecting Manage Bookmarks.

Does any of that help?

Denys, You deserve your Top 10 Contributor status! Thank you for your thoughts. You wondered:

> Are you sure there is no Manage Bookmarks option? It should be the last one, at the bottom of the menu.

As before, clicking on the top-right 3 bars elicits a "Synchronise all your devices" drop-down menu whose 6th line is "Bookmarks >". This in turn responds with - I wish 'snips' could be pasted into this text - the options: "Bookmark current tab", "Search bookmarks", "Hide bookmarks toolbar" and finally, beneath a line, "Recent bookmarks/(Empty).

> Alternatively, you should be able to open the same window by:

> Pressing Ctrl+Shift+O

After repeated attempts, success? Please see the first image below.

> Pressing Alt to restore the menu bar...

All that accomplished was to highlight "Organise" above. And this provided 10 options, all grey, with a Black "Close" " bottom.

> and then selecting Bookmarks -> Manage Bookmarks

Not displayed. To the right of Organise, however, "Import and Backup"'s dropdown displays "Restore/choose file" which does nothing and, more encouragingly, "Import Bookmarks from HTML..." and Export Bookmarks to HTML..." But clicking on those offerings also accomplishes nothing.

> Right-clicking your Bookmarks toolbar and selecting Manage Bookmarks.

Where, please, are those options? I am starting to despair. Should I restart Firefox in Troubleshoot mode? However "Your extensions, themes, and custom settings will be temporarily disabled."

I despair. Sould I restrat Firefox in Troubleshoot mode? However "Your extensions, themes, and custom settings will be temporarily disabled."

The window from the screenshot is what you need. If you have managed to open it with Ctrl+Shift+O, you don't need other options.

If under Backup and Restore -> Restore there are no options other than Choose File..., try using that one and manually selecting the backup file you mentioned. If that doesn't work:

• Indeed, try running Firefox in Troubleshoot Mode (and doing the same there).
• Make sure you are using the profile with your backup (unk14jlv.default-release-1647366062305). You can check that by:
  • Checking whether your other data (tabs/history/passwords/settings) is preserved
  • Going to about:profiles (just type it in your address bar and press Enter) and seeing which profile has the "This is the profile in use and it cannot be deleted" note. That would be your current profile.
• If you are using a different profile, try opening the mentioned one (unk14jlv.default-release-1647366062305) by clicking Launch profile in new browser. Have your bookmarks appeared? If so, set this profile as default by clicking Set as default profile.

Looking forward to your update on how it goes!

Denys, Thank you very much again for your persistence. Your first remark offers some hope:

> The window from the screenshot is what you need. If you have managed to open it with Ctrl+Shift+O, you don't need other options.

GOOD!

> If under Backup and Restore -> Restore there are no options other than Choose File..., try using that one and manually selecting the backup file you mentioned.

Ugh, this was less encouraging. If you refer to unk14jlv.default-release-1647366062305 (which doesn't look like a file to me), in the "Library" panel I clicked on the 3rd "Import and Backup heading and then selected the 2nd drop-down option which offers "Choose File". But doing so elicits no response.

> If that doesn't work:

   Indeed, try running Firefox in Troubleshoot Mode (and doing the same there).

The response here is... Ugh, as SO often the text cannot be copied. Please see the jpg below. Please, should I click on OK (although as I recall last time nothing happened. But I'll wait for your approval before proceeding since the cryptic name now is not the earlier unk14... one.

I regret being so ignorant. But what is that "address bar"? Would it be the URL above: https://support.mozilla.org/en-US/questions/1557510#answer-1790119 ?

> ...and seeing which profile has the "This is the profile in use and it cannot be deleted" note. That would be your current profile.

This SEEMS to confirm my guess.

> If you are using a different profile, try opening the mentioned one (unk14jlv.default-release-1647366062305) by clicking Launch profile in new browser.

The new browser chosen was Google Chrome. But I could find no 'Launch profile' there.

> Have your bookmarks appeared? If so, set this profile as default by clicking Set as default profile.

IF ONLY!

> Looking forward to your update on how it goes!

I fear that after this fruitless response your optimism will wane. From my ignorant perspective but also my awareness of the importance in all web browsers of bookmarks - they are, after aIl, these peripatetic programmes' roadmaps - I am baffled they don't have a standard default, EASILY-accessed file with which commonly visited sites' URLs can be recovered.

I remain grateful for your efforts.

I've just realized that your Library window (from the screenshot under your previous post) looks extremely broken. So let's proceed with Troubleshoot Mode and checking other Firefox profiles.

I'm not sure how you got the dialog in your screenshot, but I don't think that's what you need. To open Firefox in Troubleshoot Mode, you need to click the Firefox menu button , select "Help", then "Troubleshoot Mode…" and then click "Restart" in the "Restart Firefox in Troubleshoot Mode?" dialog. Then, try do to the same thing there (open the Library window, e.g. with Ctrl+Shift+O, and click Import and Backup -> Restore -> Choose File...). If a new window opens that allows you to specify a file, open the one you have found (C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4) there. To exit the Troubleshoot Mode, just close Firefox and open it again as usual.

I believe checking other profiles will make sense regardless of what you get in the previous paragraph. The address bar is indeed where the URL is displayed. I've attached a screenshot of the page you should get with some illustrations. Also, check if you have the "Profiles" option in the Firefox menu. If not, it's completely fine. If you do, you'll also need to open the profiles listed there.
