Hello, I've just set up Thunderbird on my IMac OS Monterey version 12.2.1 and have synchronized my gmail account. However not all folders have migrated. What is causing this and how can I fix it? Thanks!

i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

I upgraded from Thunderbird 52 to version 91. Even though all the account settings appear to be correct, I can neither send nor receive mail. What the -- is wrong?

My windows 10 took a powder and had to have it repaired The thing that i may not be able to get are the add ons and the address book that i had on it they are installing anew hard drive but were able to back up some of the files and such. I know it is something about address book and history but not sure how to do it .i and when it comes back can i come back and get help

The situation is bad for my hard drive, not enough room to import the outlook files into TB. So is there a way of moving the destination for the import function to another drive so I can collect my eamils to use in TB?

OR

Can I somehow split the import of the emails into 2 or three attempts then save to a memory stick step by step?

I am really stuck so any help I would appreciate please!

I experienced a problem with Thunderbird suddenly not recognizing my password. Kept giving me a notice that said my password/account had been "blacklisted". I've never seen that in 20 years. I called my local internet company, Comcast.net for help. He walked me through deleting and re-installing several times before it dawned on me that Bitdefender (anti-virus software) might somehow be blocking my password. I turned off VPN and unchecked all the boxes at Bitdefender. And I could suddenly reinstall Thunderbird e-mail addresses. HOWEVER, all the folders, which I think were stored locally (on my laptop) are gone. I had lots of stuff I use on a daily basis in those folders. How do I get them back? Can I get the back? My server is IMAP but I don't know if they were stored online or on my laptop. Somebody help me, please?

Hackers will be very happy now that Firefox automatically download their malware and backdoors. Thanks to Firefox, hackers will be able to infect millions of world computers and install ransomware and make havoc i financial, health, and other industries. Firefox will forever be praised by cybercriminals of the world.

'trying to sign on to zoom successfully, then once in I get a notification saying I need to download the lastest version, Ive tried 6 times bianary file and then nothing happens '

firefox updated itself, which normally would be fine, but now there is a PDF icon in place of my normal firefox icon, and I am afraid to use it now. Is it for real?, can I change the icon back to the old firefox one? Please let me know cause I won't use it now until I know for sure that it's ok and get it back as it was. thank you, Linda

So Firefox did an auto-update a few days ago, and when I opened the browser EVERYTHING was gone. Passwords, bookmarks, etc.

I've managed to get the old bookmarks moved over, but I cannot for the life of me figure out how to get the old passwords back. The old data is in a folder on my desktop, do I just copy and paste the login and key 4 files from that folder to the new folder?

Sorry if this seems like a dumb question, I'm a pleb and this is the first time I've experienced this. :(

bold text' I need to stop firefox from attempting to download update 99 because it will not download it and it is taking up too much of my internet metered download time.'I have taken it off of automatically download updates,but it still pops up a message every day.

I'm making this thread since the previous one was closed and provided no real solution, yet the result shows on the very top of Google. So I like to provide helpful information to others in my answer below.

Today I upgraded my TB portable standalone (no portable platform) from 60.9.1 to 68.12.1 As that what it said I could upgrade to in the about window. All worked fine. Now the about window tells me I can upgrade to 78.14. But there is no portable version portable version of that available (sorry I know Mozilla do not support the standalone version). There is a portable version of 91.6. Can I upgrade from 68.12.1 to 91.6? Thanks!

I'm using TB 91.7.0 (64-bit) on Mint Linux. I somehow deleted a folder full of messages.

I do have a backup of the entire TB folder from few days ago, but can't figure out how to restore that folder back into the main TB universe.

Everything I have found says to use https://addons.thunderbird.net/en-CA/thunderbird/addon/importexporttools/ but that apparently has been corrupted as a protest by the author.

"Apparently the add-on has been corrupted by the author. "The site and all the extensions have been made unavailable as a form of protest against the illegal fascist measures and abuses against personal rights that have been occurring in Italy (the country where I live) since March 2020."

So, can someone tell me how to restore a folder of messages back into my T-bird successfully? Thanks everyone, Barry

When I downloaded and sync Gmail to thunderbird, I encountered the following issues:

1. The number of emails on ALL MAIL folder is not the same as that in my Gmail. Thunderbird has more than 800 emails compared to my Gmail.

2. When I randomly check my emails through the search function, the emails can not be found on the location it states thy are. Ex. location=all mail , but when I search ALL mail , the email in not there.

3. SAME Email but the timestamp in Thunderbird is 1 minute less than the time stamp in the Gmail. Ex. In Gmail time stamp is 11:04 am , in thunderbird it is 11:03am

4. Also can I change the Date Pattern in Thunderbird from DD/MM/YYYY to MM/DD/YYYY?

Thank you!
