I-Firefox Community Forum

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 have to do a clean install of Windows, how do I save all my firefox bookmarks and passwords as well as Thunderbird addresses and any other info I might want to import back into Firefox and Thunderbird once I've installed windows again.

I can't sync my history and bookmarks. As for my bookmarks, backups have stopped for about a month. I can't export them as html files either. As for my history, the file download history is no longer displayed at all. I've tried refreshing Firefox, but that didn't work. Is a reinstall the only solution?

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,

For several days now, I have been unable to use Bank of America login and passwords. The login appears correctly but the password fails to appear. Also I can not put in my password. What is going on?

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.

I run Linux Debian 12 (bookworm), and there seems to be no way to disable Firefox from automatically starting up after system boot. I've searched through settings, read countless articles on the internet, looked at system auto-startup applications, but wasn't able to find anything that worked. I even looked in about:config, but couldn't find anything. Firefox isn't automatically started by my system and there is no parameter that disables it. I also didn't click through any choices about autostart when I first opened Firefox.

Hi Firefox community,

I’m currently testing a simple HTML-based site hosted on epizy.com, where I provide information and visuals related to a game mod (NullsBrawll). While everything works fine in Chrome and Edge, Firefox often fails to load key assets — especially images and script files that showcase the game’s content or guide users through the APK installation process.

Some problems I’m running into:

Game-related images (e.g., character banners, gameplay screenshots) fail to load intermittently JS-based animations or carousel sliders showing features don’t always run This issue happens more often on mobile Firefox Other browsers show the same files fine, even on slower networks

I’m wondering if:

Firefox handles free-hosted static files differently than other browsers? There are known issues with HTTP resources from epizy.com on Firefox? Any specific headers, caching rules, or SSL setup I should be aware of?

Thanks in advance for any help! Just trying to make the Game experience smooth for all browsers.

Firefox updated last night/this morning. Bookmarks all gone. I find the backup data. My profiles don't have any data for some reason. I manage bookmarks, go to choose a file to restore and nothing happens. None of the other options work either. I tried to add info about my system/version here but it reset this request and said it couldn't find any troubleshooting data. Probably because I have none. Please help. Why won't it let me do anything.

I had an old computer crash - The hard drive is still good bought a new windows machine. How do I get all my book marks and setup from old computer and install on new windows 11.. Under Program files (x86) I found mozilla Firefox and program files. The data in Program files is from today so that should be updated.

How do I get all of the passwords and book marks out of this and reinstall into new firefox
