Firefox Community Forum

Firefox just updated today and wiped all of my bookmarks and passwords. I need them to be restored as it included my login information for vital personal services such as my online banking, health information, etc. I hadn't saved this information anywhere else.

The passwords seem to have been stored in a login.json file, however, copying that file into my Firefox profile folder doesn't restore them.

Any help would be desperately appreciated.

Hello Mozilla team,

I recently received an update for the latest version of your browser and installed it. However, all of my bookmarks appear to be missing. I have an HTML backup of my bookmarks stored on a USB drive, but when I attempt to import it into the updated browser, I receive a message stating that the file is not recognized as a bookmark file and cannot be uploaded. This is unusual, as I am able to import the same HTML file on other computers and browsers without any issues.

I also tried using the “Sync” function to restore my bookmarks, but this did not work either.

Could you please advise on how I can resolve this issue?

Regards, James

I just went through this a few days ago but once again find the message ""The bookmarks and history system will not be functional...." I have recently downloaded and used CCleaner7 and wonder if that app is causing the problem. Help, please!

Hello,

To explain the issue at hand I will copy the email I sent on Sunday to the Mozilla support team, by a member of which I was subsequently redirected here.

I am looking for a solution to a serious issue that occurred on my Mozilla Firefox browser on Thursday this week. It concerns a website called blankslate.io, which I use very frequently for taking various notes. On this site, it is possible to create a permanent account for storing one's notes, which I did not do because I thought it would not be necessary (though after this incident my mind on that has been changed). Without a permanent account, the notes taken there are saved locally only on the specific browser in the specific device. Onto the issue itself. My PC had been running critically low on memory, and, because of some misleading information I had received, I thought it was not possible to free more than only a very small amount. On Thursday, while I was playing a game, the remaining amount ran out (which surprised me because there had still been enough for everything to function properly when I checked before starting to play). To free some memory space, Firefox then performed an action which I will not be able to identify (please describe to me what this action was if you can) that resulted in me getting logged out of websites in which I have created accounts. I had no trouble logging back in everywhere except for blankslate.io, where, because of the way the notes are saved on the specific browser only and my lack of a permanent account, I now have no way of accessing my work, the site displaying a message of "This note is private" if I try to open one of my saved notes from either my browser history or my frequently visited sites. Neither is there any way of contacting the website's developer, because of the site's nature, or finding advice online, as the site is not a widely known one. Is there any way for me to regain access to the notes I had saved on this PC's Firefox browser? I still have access to all of the notes I had saved on a different browser or on different devices, so all of my work has not been lost, but this PC's Firefox browser contained, among others, my single most important note, one I have been using daily for 5 years and am highly distressed about not being able to access anymore. Please get back to me at your earliest convenience and, if it is possible to provide me with a way to resolve this issue, I will be immensely grateful.

Thank you for taking the time to read my request, I truly hope there is some way someone can help. (I can add the optional troubleshooting information as well in the case the issue can be solved with its help)

I had already done as Paul suggested, but there was only one profile listed, named Default. I have found the place where the profiles are stored, and I have a private back-up (.json file). But none of this is useful if Firefox won't open the Choose File window from the Restore option in Library. What else can I try?

it's my fault and i don't know what i did: set FF to always restore previous session but closed several multi-tab windows when tabs were restoring, including - i think - truth.social.com, which was carrying one of those windows, possibly misusing the restore all tabs selection.

the best way to help is for you to draw a picture of me, deleting by mistake, and then reporting to you.

i will continue on my own, reviewing the "help" focusing on "restore", and will put as many tabs (ugh) back in windows they belong in. don't worry. it was me, and the effort will be worth it.

thanks for everything moz and FF.

FIrefox version 145.0.1 on a Windows computer.

Recently, whenever I open Firefox all my bookmarks are gone.

Booksmarks Toolbar is set to Always Show.

The only way to make them show is to uninstall and reinstall. And I have to do this every single time I turn on my computer. Getting very sick of this very quickly.

hi there - rather annoyingly =

I have deleted my preferences by accident and I can't get them back off time machine or in the trash,

fire fox won't open as it says preferences missing -

and I keep going around in circles getting nowhere -

any help greatly appreciated! - many thanks!

My bookmarks and history disappeared from my mobile Firefox. Maybe because I took some permissions away? Not sure why that would destroy a few years history and bookmarks I count on being visually impaired.

Any way to get them back, thanks for your help!
