My HP Omen has 2 hard drives. Originally, Firefox was installed on the C: drive and working perfectly. In order to clear up space, I tried to use the Windows Move feature to move the program from the C: drive to the secondary (and larger) E: drive. Since then, Firefox won't work aside from opening a Firefox window. It will load no pages, settings, etc.

I've tried uninstalling Firefox from both the C: and E: drives. Searched for any remaining files and deleted them. Deleted Old Firefox Data folders. I've reinstalled Firefox, without the option of where to install it, but it still fails to work at all. I get an error message regarding a missing file, VCRUNTIME140_1.dll. I've searched for the file and it's NOT missing. It is in both the Firefox folder and the Windows/Systems32 folder.

I've searched for data in the Users folders that might relate to Firefox but NOTHING seems to work that will allow Firefox to work again. I've tried putting Firefox in Troubleshooting Mode but it won't restart as it says it needs to. It just won't work!

If anyone can just tell me how to COMPLETELY remove Firefox from both hard drives so that I can just do a clean, new Firefox install, that would be preferable. I know how to import bookmarks from Chrome.

If anyone can offer some help for someone who isn't great with computers, I would greatly appreciate it. If you need any other information, please don't hesitate to ask.

I have done many searches via Google on how to migrate Outlook 2016 Address Book(s) to Thunderbird and have not found one that does the job.

I did find a suggestion to use Thunderbird V31.8.0 to migrate the Outlook Messages & Addresses. This worked; however, then could not find a way to do a clean migration on up to V91.10.01.

Any good solutions (free) that will work?

I have changed from Ubuntu to MX Linux recently and have kept my Thunderbird profile data.

On MX TB 78 is installed.

When I copy the Ubuntu TB profile folder to my new MX install and start Thunderbird I get a message saying that "You have launched an older version of Thunderbird" (which is not the case, I launched versions 78) and that I can either create a new profile or quit the program..... Not very useful.

How can I use/import the data from my previous (Ubuntu) install? It seems likely that I had version 78 on Ubuntu as well, my system was up-to-date, but of course I can't check that anymore.

Thanks

I am moving Thunderbird to a new Windows 11 (64 bit) machine, and downloaded Thunderbird 91.10.0. I used a new profile when I created my two email accounts. But there are several problems: 1) when I exit, Thunderbird doesn't close down completely 2) when I try to look at addons.thunderbird.net or Release Notes from within Thunderbird, the new window never loads (on the other hand, this means that there are no add-ons to confuse the issue) 3) Thunderbird occassionally crashes. I can send you Troubleshooting Information if you need it; it means nothing to me.

The above is the simple version of the problem -- I have been working on this for 2 days, and am no closer to a solution. Any help would be appreciated.

Hi, just bought a new laptop which is loaded with windows 11, and I cannot download Surfshark vpn, I go to google and it will not even open any surfshark page, I assumed it must be something to do with safesearch, so I clicked on the safesearch button but it does not give me the option to turn it off it just states 'You don't have permission to change your SafeSearch setting. It's locked by the device or network that you are browsing on' !! how do I get over this? any help appreciated,

I am a long time Thunderbird user. I am moving to a new PC. I used the procedure that you recommend to move Thunderbird (excellent, easy-to-follow), but it only moved one account.

I had one Verizon.net account with another Verizon.net alias to that account. When Verizon switched their email hosting to AOL (they bought both AOL and Yahoo) the alias became the account and the account became the alias. To Thunderbird, it looks like two different accounts.

After the switch, I continued to store emails in the now-alias account folders. When I restored my 23 GB of emails, the alias account folders did not transfer.

Since I stored some vital information in those folders, I need to either (1) copy the folders to my new PC or (2) keep my 11-year-old PC running. What should I do?

I just needed to reset my kindle hd 10 to factory. When I try to sign in to firefox in order to sync bookmarks, the page won't open but only spins. I was able to sync bookmarks when I bought the kindle in December. Thanks.

I would like to save my Firefox profile data into my computer as I would like to transfer the data to a different computer. Is there any solution to how to save it down?

Hi, I have some issue on the new updates on Version 101.0.1 (64 bit) Firefox auto-download all my files even when I am in view mode. Is there a way to disable this feature?

I'm not exactly sure what this is called. Maybe it's in the cache, but I don't know. One of the fastest timesavers I have is that I use the Firefox url feature that makes suggestions as soon as I start typing a url. I pull up dozens, possibly hundreds of articles that I refer to frequently this way, so that I don't have to bother bookmarking them. I don't clear the cache, to keep these references from disappearing. I have to move computers now. My longtime mac is not working well anymore. Is there any way to bring these url suggestions with me when I migrate? Thank you.

I recently had to re-install Kubuntu 20.04 on a laptop. In the process of setting up Thunderbird, the installation process said it had found address books and asked if I wanted to connect them. Sounded like a time-saver, so I said "Yes." What got connected were several completely irrelevant files, most CSV contacts from my cell phone, but the extensive .mab file from the old version of Thunderbird was not there.

I have found some proposed solutions that tell me to

 >> shut down Thunderbird,
 >> rename the abook.sqlite files in my profile folder,
 >> copy to the old abook.mab file (which I have on a backup disk) into my profile folder, and
 >> restart Thunderbird, which will than automatically convert the old .mab file to the new .sqlite format.

That doesn't work. First problem is, I don't have a "profile" folder. I do have a profile.ini FILE which points to two other folders named (approximately) a1b2c3d4.default and z9y8x7w5-default-release (I've changed the exact names, but the name format is as shown).

Second problem is, my a1b2c3d4.default folder (which, in older versions, was where my abook.mab file was found) had no .sqlite files. My z9y8x7w5-default-release folder has several such files but named abook-4.sqlite, abook-16.sqlite, and abook-17.sqlite. They are all shown as 256 KB. When I added the old abook.mab file to that .default-release folder, it did produce an abook.sqlite file, also shown as 256 KB. But the old abook.mab file's content does not appear when I restart Thunderbird and look at the address books. No abook.sqlite file was created in my a1b2c3d4.default folder.

The references I've found so far appear to be for Windows installations, so I'm hoping someone will have suggestions more suitable to the Linux environment.

My old Windows 7 PC laptop died. I used Thunderbird with a personal profile gmail address I will call Profile 1, and another email address I created from my online website that no longer exists, and I will call it Profile 2. I'm now running Windows 11 on a new PC. I downloaded a new Thunderbird program on the new PC. I attached the old Win 7 hard drive to the new PC and used Mozbackup to restore my old profile using my previous .pcv file backup. Profile 1 restored, but with emails only back to 2017. Profile 2 was not restored at all. Please help. Thank you.

For reasons that will likely never be known Thunderbird stopped yesterday. Clicking on the icon showed the spinning icon for a second or two and then ended without the application starting. It had been running flawlessly for several years.

I checked with task manager, nothing from Thunderbird. I restarted. Same problem.

So, I found and installed the beta version which is working fine but I've lost my address book and message filters.

I can re-create the filters easily, but would prefer not to have to re-create the addresses. Is there a way to find the old address book(s) and use them?

Thanks -dmd-

Since upgrading from the immediately previous version of TBird to 102.2, I can no longer dl GMail popmail. TBird does not even attempt to download. It also doesn't attempt to download from another account when I tell it to manually download. It downloads on auto from that 2nd account, but not manually and not from GMail at all.

Today I upgraded from TB 92 (ish, not sure exactly) to 102 and am having a problem with unified folders.

I have five email accounts in TB, and use unified folders. In the previous version, if I clicked on a single account under Inbox, I would see emails in the inbox for just that account. Clicking on the top-level Inbox node would show me all emails in the inboxes of all five accounts.

However, in v102, when I click on the top-level Inbox node, the messages panel does not change. Whatever was there before remains.

If I click on the top-level Inbox node, then restart TB, which starts it up with that node selected, I get a panel that has various buttons for setting things up, about TB, etc.

Is there a way to go back to the old behaviour, and have the top-level Inbox node show all inbox messages?

Thanks

After I installed 10.x (over 9.x) every time Thunderbird starts I get the attached error message. After I click OK the issue seems to disappear and when I click Get Messages, I get them. Best Wladyslaw Janowski
