Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

You guys keep hijacking my browser and stopping all my work on a near weekly basis. Shutting down my ability to work on projects and stopping my browser from functioning in the middle of use. I can't even pay bills without you guys interrupting my browser with your bullcrap.

This is unacceptable. I've gone through great lengths trying to stop you from hijacking my browser. I installed a policy generator and followed the instructions to put a policy in. I uninstalled Firefox's background updater tool. I disabled automatic updates in the settings to the best of my ability.

I've gone through everything I can think of trying to stop your forced updates. Its unethical what Mozilla is doing to its users. I even tried to lock policies with admin only authorizations but firefox couldn't read the file anymore when I did that. I did confirm today that the policy file was still working, when Firefox ignored it and shut down my browser till I restarted it. I confirmed that Firefox is blatently ignoring policies.

I just checked and Background Maintnence was installed again when I didn't want it. You're now installing software against my will too? What the hell is going on.

Once again, when I updated Firefox, it changed a LOT of my settings, including displaying the toolbar and open tabs bar.

When this happened last - months ago - it seems Mozilla realized this had happened to a lot of users, and managed to restore us to all the information that had been "lost".

I hope you can do that again, and can find a way to not put at least ME, and I'd bet a lot of other users, through the OMG!!! What do I do NOW?! panic.

Happy Holidays.

I have a Windows 11 pro laptop with 66,000 emails in the inbox on Thunderbird. Most of those emails have been long since been deleted from the gmail server to stay within account limits.

I have a new Oneplus 13 phone running Android 16 which has the Thunderbird app (version 14). I setup the profile and it has loaded the emails currently on the gmail server. I would like to load all 66,000 emails currently saved on the laptop.

I copied the laptop Thunderbird email inbox file to a USB-C flash drive thinking I could copy that file onto the Android. Unfortunately, I learned that Android since version 11 or so limits access to its data files. My phone is not rooted so I don't have access and am unable to copy the inbox files into the androids Thunderbird storage file.

Is there a way to copy old emails from the desktop Thunderbird to Android?

I have several users that are running Firefox 137. When attempting to update, they get the message that the organization has blocked updates. There is nothing I can see that we have done. Attempted to update registry and .json file. I cannot find where the block is coming from. Do I need to delete and reinstall?

This refurbished laptop was purchased from Best Buy in August 2022 with a Windows 10 OS. When a free upgrade was offered by Microsoft to Windows 11, it was accepted. Why are there no drivers with a version 11 prefix?

can someone please tell me why firefox is trying to install this unwanted file.....i run bitedefender everyday and everyday this pops up it is ANNOYING Online Threat Prevention

firefox.exe attempted to establish a connection relying on an expired certificate to sync.contextualadv.com. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk. Add to exceptions

I have no idea what I have accomplished and what I have to do next. I am here because I cannot access my current email account,and neither can you. I paid $20 but I still see a pay page. Get Thunderbird installed and working. I had Thunderbird years ago and lost it, I think someone wanted me on the foxinternet.com program. Assume I am a new person to access the internet.
