On Firefox browser, I cannot Copy a file in Studio Code Server (within Home Assistant). SCS is open in HA in a Firefox tab. I get the error popup "Unable to read from the browser's clipboard. Please make sure you have granted access for this website to read from the clipboard." "Learn More" links to https://code.visualstudio.com/docs/remote/codespaces#_how-do-i-allow-vs-code-to-access-my-clipboard-for-reading and the "How do I allow VS Code to access my clipboard for reading?" section. But I cannot find similar settings in Firefox's Settings menu.

Any suggestions please on how to resolve this? I'm sure I used ~ a year back to be able to Copy a file ok in VSCode on Firefox. Thank you.

I got a new Windows 11 Dell XPS laptop computer and installed the latest Firefox (v133) on it. On my old computer, it was supposedly syncing/saving the bookmarks in the Mozilla cloud or somewhere. However when I try "Import" on the bookmarks panel, it only offers to import Microsoft Edge bookmarks. When I follow the help docs on this forum, it says to use the hamburger menu to go to bookmarks and then to "Manage Bookmarks" which took me a while to find since it's at the very far bottom of the Bookmarks window, not near the three menu items at the top. Anyway, it brings up a window with more bookmark items but they all seem to deal with my current computer and installation of Firefox, which has only a very few default bookmarks. I do not see anything related to bookmarks synced with the cloud. I am logged into Mozilla on the new computer. I do not have an HTML backup file available, since I thought that the bookmarks would be backed up to the cloud and I could always get them there. Two questions:

1. 1: Is it possible to get my old bookmarks from the cloud?

1. 2: Is the bookmarks have not been exported to an HTML file, is it somehow able to get them from someplace on the C drive of my old computer? I think it should be possible since the bookmarks must be saved somewhere otherwise, how would it know what the bookmarks are for someone who never exported them to an HTML file? My old computer won't boot due to a power surge but I am able to connect it's hard drive to my new computer and see files on it.

Thanks, Mark

Hello there. I had to recently wipe my computer on 4/12/2025. I forgot to sync my bookmarks and passwords. Is there any way I can possibly get these back? I don't know how far back Mozilla itself keeps files, I've been told they do but I'm not sure how far back.

Dear Support Team

I hope this message finds you well.

I am reaching out to report an issue I am currently facing. I recently changed my device, and upon attempting to sync my Mozilla Firefox account on the new device, I noticed that all my data—including bookmarks and saved passwords—appears to be missing.

Please note that my previous device is no longer in my possession and has been formatted, so I no longer have access to the original data.

I would greatly appreciate your assistance in recovering my data and saved logins, as many of them are not stored in any other browser.

Thank you in advance for your kind support. I look forward to your response.

Best regards,

I last sync my data on 31, August,2025 and delete all password from the device now I only have my passwords and bookmarks etc all data sync to Firefox account. And today I tried to login back to get my passwords, I forgot the Firefox account password and reset the password by clicking on forgot password and reset my account password. But my all synchronized data , passwords, filling forms, bookmarks all gone and I had nothing left. Kindly give me my data and passwords back and if you need any verification from me that it's original me person. Kindly cleanse give me a backup of password as I really need them. My all PhD thesis , all data there and I didn't remember any passwords. What to do now. I am very much depressed please help me out

I'm trying to configure Firefox on Mac using our MDM. The goal is ultimately to control a bunch of settings, but I'm trying to start simple by just installing the 1Password extension.

When I deploy this .mobileconfig file, nothing seems to happen to Firefox. I made this by following the example at https://github.com/mozilla/policy-templates/blob/master/mac/org.mozilla.firefox.plist but it doesn't seem to work and I am not sure how to debug.

<plist version="1.0"> <dict> <key>PayloadContent</key> <array> <dict> <key>PayloadContent</key> <dict> <key>org.mozilla.firefox</key> <dict> <key>Forced</key> <array> <dict> <key>EnterprisePoliciesEnabled</key> <true/> <key>Extensions</key> <dict> <key>Install</key> <array> <string>https://addons.mozilla.org/firefox/downloads/latest/1password-x-password-manager/latest.xpi</string> </array> </dict> <key>PasswordManagerEnabled</key> <false/> <key>ExtensionUpdate</key> <true/> </dict> </array> </dict> </dict> <key>PayloadEnabled</key> <true/> <key>PayloadIdentifier</key> <string>e441f671-148a-4039-a45d-12514e6d92b2</string> <key>PayloadType</key> <string>com.apple.ManagedClient.preferences</string> <key>PayloadUUID</key> <string>e441f671-148a-4039-a45d-12514e6d92b2</string> <key>PayloadVersion</key> <integer>1</integer> </dict> </array> <key>PayloadDescription</key> <string>Installs the 1Password Firefox extension for ease of use.</string> <key>PayloadDisplayName</key> <string>1Password Firefox Extension</string> <key>PayloadIdentifier</key> <string>77dc9f8b-aaee-4f91-93ba-30b81cc6a31b</string> <key>PayloadOrganization</key> <string>Exogee</string> <key>PayloadRemovalDisallowed</key> <true/> <key>PayloadScope</key> <string>System</string> <key>PayloadType</key> <string>Configuration</string> <key>PayloadUUID</key> <string>77dc9f8b-aaee-4f91-93ba-30b81cc6a31b</string> <key>PayloadVersion</key> <integer>1</integer> </dict> </plist>

After the last update I can no longer see the comments section at the bottom of news articles on both Fox News and Yahoo. I double checked and they are workin fine on Chrome (I never this browser). I have been using FireFox for years and this is the first time this has happened. I am using Win 10 Any help would be appreciated Thank you

My firefox recently crashed (f5ea38ba-f4f8-4224-8ab8-982e19cc72f7) is the crash code if that helps it happened just now, i dont have any additional profiles and no folder such as "old firefox" is there any way i can recover all the information and my old settings or passwords or anything? I tried to log into my firefox account to sync up data but there was no update on the information

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

So.... I ended up getting a new laptop and I signed in on my mozilla account and it turns out I have lost everysingle bookmarks/saved stuff / passwords etc....

Now... the thing is I do not have my old laptop anymore cause it doesn't even turn on.. I did not make a backup cause I thought all this information is saved online...

What do I do now to get my old stuff back???

Thank you

Hello Firefox team,

I did update my Mac to IOS 26.0.1 and I have lost all the history and bookmarks, I have the "Sync" enabled with my browser.

All my important data has been lost, can you please look into this and help me please.

Thanks, Sajeel Irkal

Hello, I recently used the option to sign out while also checking the box to delete data from the device. I was under the impression that once I had the new computer I could just sign into my account and my synced data would be there. This is not the case, because I can't even get my bookmarks and what not back on the device that I originally signed out of. I'm pretty sure I am on the right account so why is everything gone even though it said that synced data will not be deleted? Am I cooked? Losing all my keys and bookmarks is going to suck so if anyone could help me, that would be much appreciated.

After Windows crashed, I installed a new system and logged into Firefox using my account. But all my history, passwords, bookmarks were erased. I also went to my phone and everything was gone. I didn't erase anything myself. Is there any way to restore the previous state of the account? Are there any backups on the Firefox Sync server?

Hi, I'm new to asking the Firefox community a question, but I hope you can give me directions to solve my problem:

I currently have Firefox v. 78.15.0esr on an iMac (early 2008) running OS 10.9.5.

I know that version has been unsupported by Mozilla for a few years, but I still want to keep this computer alive after I install the latest Firefox version to the newer (refurbished) iMac M3 2023 which should come with OS 14 or OS 15.

I hope that downloading the latest Firefox for Mac version off your website should be pretty straightforward, but what I really need help on is how to bring my Profile residing in the Library/Caches/Firefox folder on my older iMac to become my Profile on the latest Firefox version on the newer iMac (while still keeping my older iMac).

Appreciate the help.

I know the system backs up bookmarks every day or so. I want to migrate all to a new PC. With a new Laptop it seems to have done so automatically, maybe through synchronize feature, I am not sure how I did that . I normally export bookmarks to a external flash drive as HTML. Just did also to a .json file type cannot find how to do that. Which format and method will be best? Have all of the old PC backed up through Acronis full back up. Will that have the full Firefox program with the bookmarks?

Hi,

I can't seem to retrieve all of my Firefox bookmarks or passwords on this new mac laptop. My other (mac) one fried. I thought everything was saved on Firefox.  Tried to sync from phone (android) too. Therefore, I'm having a hard time logging into certain accounts, which I depend on Firefox for my saved passwords. (evidently that is a thing of the past and I will now write all passwords down in a safe place. Also does anyone know why when I scroll on my mouse I have to scroll up, in order to scroll down, more importantly how can I change it back. This is a new glitch. and I'd rather not get used to it! Please help if you can.

Thank you, techno dummy Noel lol
