Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

Since the latest Firefox update, the color of the letters appears black on a gray background, making them invisible. How can I change the colors of the bookmarks sidebar? Thanks in advance.

Yesterday I upgraded my PC from Windows 10 to 11. Today I discovered my Local Folders are not visible. Searching tells me the messages still exist, but TB does not show the folders. I did the same upgrade a month ago on a laptop (Windows 10 Pro to 11), no problems. I didn't externally back up the messages as I am a dinosaur and don't know how, but at least they are still on the hard drive. Thousands of them though so I need the local folders back. Tried all the fixes I can find on the Community Forum, without success. Can anyone help please? Bob

Dear Team, I was asked to start an upload in Firefox. I tried that. I get the message 'Couldn't load XPCOM' What do I have to do to restart Firefox? It's urgently needed for account verification! Could this possibly be due to a lack of capacity? I currently have 371 MB of 111 KB available. I ask you to help me quickly - thank you very much.

I have been having using Thunderbird as my email package for over 10 years and lately have been having issues. I was looking to cleanup the install (version 140.5 esr) and noticed an older version of the app still exist on the computer (version 68.4). will deleting this version have any implications. This computer was originally Windows 10 but has been upgraded to Windows 11 when the problems seemed to start appearing.

Error message end. however I cannot find any incoming server mentioned for this email address anywhere in the settings or data. anyone have an idea where to search for and delete that server ? I will be very grateful for any help.

Thunderbird app on Android suddenly stopped moving emails; instead just repopulated inbox. Uninstalled and reinstalled app; added email account and proper password. TB locked into "Checking incoming server settings" loop. Comcast properly set up; accessible from browser. Tried entering settings manually; same result. Cleared cache and data; same result.

I am trying to restore my Thunderbird/Mozilla account, and get the following message:

Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server.

Any help would be appreciated, thank you.

The Internet told be Thunderbird is the best way to Download Linuux Mint Cinnamom. I am 94 years old and cannot figure out how to do that. Can you give me detailed steps I can take to do that?

The profile manager goes out of it's way to provide all possible options *except* the one that's needed most:

How to simply "switch" from one profile to another profile?

When a new Thunderbird installation is created, all profile operations are limited to the profiles created when Thunderbird is installed. Other profiles that are available in the right location under Users\---\AppData\Roaming\Thunderbird\Profiles\* are simply ignored without any possible, or at least obvious, route to switch to them and / or activate them. Why?

This issue is a real problem when attempting to migrate existing Thunderbird settings, mail data, etc., from one physical workstation to another. Fortunately I found a fix by grabbing the mail\pop_account folder under the old profile and plugging that folder into the new profile. Still there was additional aggravation associated with lost settings, another import / export for the calender, etc., etc.

Again, why does this have to be difficult?

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.

Hello, During a recent software update not long ago, I lost my entire Spell Check ability and Dictionary's won't even load anymore. I figure I need to delete the program and reload, but I'm afraid of losing all my folders that have been created over the years of using Thunderbird Mail.

Could someone please explain the procedures for me to delete and reload without losing all my important folders. These folders have years of important emails stored in them.

Thanks a bunch!!

I installed Thunderbird v128.2.0esr to a new laptop and cannot find the table view/card view icon for configuring the message list and its columns. There is no longer any icon next to the quick filter bar, it seems to be gone in this version.
