I thought that synchronization would save my data so that I could prepare my PC for reinstalling Windows. As a result, after all the procedures and installing the Browser, synchronization does not restore my data. It's very disappointing. And the history of old sessions is completely erased.

I've been trying to get this computer to work. The last time a clean install was done a few days ago Firefox immediately remembered my favorites, extensions (or one important one of them) and the configuration of the browser.

Thanks for your Help

p.s. I sense there are changes at firefox. is there something I should know?

Hi there,

I know this is dumb, but I cleared my iMac's cache and nuked my entire history, password and bookmarks. This is catastrophic :( Can you please assist with any steps that may be able to allow me to recover this data? I have icould and it's synced, and I have a Firefox account but I cannot seem to find any way of restoring or accessing some backup. Please advise. Thank you!

I'm not sure I have the right topic as I didn't see what I will try to say. The problem is when I send an email (googlemail), I cannot insert a photo/picture in the email. The only thing I can do is attach which I do but want it inserted too. This only started happening about 2 weeks ago. It is now to the point where I have to use another browser to get it to work as it should. Any ideas why?

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

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,

Hi, I just switched laptop< I no longer have my old one. I thought I'd just have log in to Firefox to recover all my information, like bookmarks and saved passwords, but now that I'm logged in, I can't find any of that. Is it possible I didn't save it? Can you help me recover it?

Thanks in advance.

Hello, my computer crashed and needed a fresh install. I installed Firefox on a fresh drive, rest the password as I couldn't remember it on the first try (I now know what is but it's already reset) and it shows me 0 bookmarks, 0 saved passwords, 0 data and keeps reminding me to "finish setup" by importing bookmarks from another browser but my bookmarks were on Firefox.. After password change I was kicked out of my FF account on my phone so all the data is still intact on my phone. I haven't logged in my phone yet. How should I proceed to restore them on my pc and sync the to bookmarks from my phone and not the other way around?

i reinstalled windows and re downloaded firfox i logged into my firfox account like a normaly doo to get all my data but non of my data is getting synced it always works but it is not working no i need my data i have my passwords to all my account on it pls help

Hi. I used braindead the backup function in the bookmark tab (see picture) After that all my bookmarks are gone. I thought its not a problem since im always sinced with firefox, but guess firefox already sinced my empty bookmarklist or i just dont know how to get the old one. I made a fresh windows install a few hours ago, so i guess i dont have a local backup on my pc. Kinda funny that Firefox does a backup right after a new install, but not when importing a bookmarklist.

Is there a way to get an old backup out of my mozilla account, or are 10+ years of saving bookmarks just gone?

I'm receiving this when I log on to Huffington Post. Never had this happen before. What's going on?

So recently I had reinstalled windows and reformated all my drives, I am also sure that this account is my only firefox account. But when i checked the sync data it shows only 1 sync data which is today 14/3/2025. I am also sure that I had left all my sync data as default therefore it should have automatically sync. But currently I do not have access to my bookmarks, etc

None of my saved passwords in my Mozilla account are showing up when I switch laptops and try to logon to various sites. Instead I have to manually enter the passwords for the sites every time even though the sites show that I have saved passwords for that site in my Mozilla account. When I type the password in a old or new site, Mozilla doesn't even ask if I want to save the password anymore.

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.

Hello, I have a mac os high sierra version 10.13.6. Google meet has stopped working since yesterday. I updated firefox (115.19.0esr). That doesn't work either. Do you have any advice for me? I hope! Thank you so much! Marie Dupuis
