Exported my Firefox bookmarks from my HP DESKTOP to a flash drive and now need to import them to a new Dell laptop. Installed Firefox on my Laptop and it had a statement that stated import bookmarks. Tried it but didn't work. Both systems are Windows 11. was not logged into Mozilla when it was performed. Plan to use Dell laptop as backup to my desktop computer.

I installed thunderbird on another mac and used these directions to try to transfer all my info and configurations from my other mac: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

When I copied and pasted the profile from mac #1 into the Thunderbird/profiles files in mac #2 then launched TB I get a message Profile Missing: Your Thunderbird profile cannot be loaded . it may be missing or inaccessible.

I tried to paste the whole folder into profiles and I also tried to paste the content of the profiles folder into the new folder 7n1rgaj8.defualt, within profiles, see image attached.

once I close the error message TB closed down.

Any help would be greatly appreciate.

thanks

I recently downloaded Firefox and was trying to import all of my Chrome data, including my bookmarks. For some reason when I go to import my browser data, there isn't even a option to import bookmarks. One of my other chrome accounts has the option to import bookmarks (a old work account I no longer use anymore), but my personal account just doesn't have it. Am I missing a step in this process or is there something I need to do on chrome to make my bookmarks accessible to Firefox? I really don't want to go in a manually add all my bookmarks..

The method I found successful in creating my Thunderbird profile on a new PC was different from the posted method. I hope this method helps others. Both Ubuntu 24.04.4 Mate and Thunderbird 155.0/ On the source PC I copied the .thunderbird folder to a USB drive. On the destination PC I opened the thunderbird folder (not hidden). Copied 123xyz.default and 456pqr.default-esr to this folder. Replaced profiles.ini with profiles.ini from the source PC. Opened Thunderbird and found my familiar experience.

I wish to back-up my Thunderbird profile, but apparently, I am to find an "export tool" under the "tools" menu. Unfortunately the option to 'export' does not appear in the list [but "import" does...!]

My old Widows 10 computer died. All I have left of it is the last full Acronis 2020 backup. I have installed Thunderbird on my new Windows 11 computer and want to restore my Profile data from the backup. How do I find them? Have been searching for days and can't find anything like in your profiles help article.

If I can't recover the data can you at least send me my current license key?

Hi, Need help with maps that cannot be removed. Thunderbird downloaded my map configuration, after a new Thunderbird installation, from my online account/my internet provider which was OK. After that I removed all maps on my online account but the maps in Thunderbird is still there but out grayed and I cannot delete them?

I uninstalled Thunderbird and also removed Thunderbird associated maps under %AppData% and %LocalAppData% but when I do a new clean installation same maps shows up in Thunderbird again? I waited some days and did a new installation again, but same issue. I have also deleted everything in W11 cash memory.

Attached picture shows the out grayed "NyMapp and subfolders" I cannot delete. How do I get rid of those folders?

Any help is appreciated.

I want to copy my windows Thunderbird profile to Linux but my Profile Directory will not open when I press open directory. I downloaded Thunderbird from the Zorin app store, and it may be a flatpak or something – it won’t tell me now because I have already installed it – but I believe that could be a reason for the directory not opening. Is there a non-PC-literate way of finding out and fixing this?

Trying to import saved passwords from an OpenOffice file on Windows 11 but FireFox refuses saying there are incorrect or no column headers.

When I open the file myself there are column headers using UTF-8 ...... must they be in a sequence or something?! Specific headers?

FireFox Version 153.0.3 (64-bit)

I have installed version 153 of Firefox for Android (see attached screenshot).

The release notes say that it supports importing bookmarks from csv files. https://support.mozilla.org/en-US/kb/importing-bookmarks-firefox-android says to tap bookmarks and then tap the menu icon at the top.

When I go bookmarks THERE IS NO MENU ICON (see attached screenshot).

What is going on?

With a new Thunderbird installation on Windows 10 Pro, I attempted to import my profile data from a Postbox on another machine. The process failed, citing two errors (see attached screen shot), EmptyDatabase Error: "blocklists/addons-bloomfilters" has not been synced yet Uncaught NS_ERROR_FILE_NO_DEVICE_SPACE: Component returned failure code: 0X805200010

The profile being imported is pretty large -- around 20Gb, so I wonder whether I have surpassed some capacity limit. I was doing this via the Import Tool on the Tools menu.

Porting my legacy mail folders is crucial. Any help would be greatly appreciated.

I can't Import bookmarks from chrome, the option is missing. Everything else worked, and the option is not "hidden", when I clicked to import bookmarks were not imported.

Good evening. This might be a tough one and not sure if it is even possible. I have had Firefox on my Dell Desktop for about 6 years. Over that time I have made many tweaks via about:config to get it working and looking as great as can be. I did just purchase a new HP desktop and downloaded and synced Firefox. I was also able to set up the new PC next to the old one to make sure each settings menu is exact. But the appearance is off on so many levels. I have no idea how many tweaks I have made over the years but have no idea exactly where to start. I did not know if there was any way on the older PC with those tweaks made to get a log of some sort of what I changed on that Firefox.

Even with the settings menu exact in both versions I cannot figure out what changes I had made. It's not many but enough. I know it is crazy but here is 2 screenshots. The one on the right, the smaller one in general is from the old PC and how I want it to look. I have tried tweaking zoom and text on the new PC and it has been a disaster, hence looking here.

Thanks in advance.
