I've discovered that network errors cause filters to be disabled and the target rule deleted. This has caused me to have to go edit dozens of rules to get filters working again.

I have seen this with two scenarios: 1. Expired certificate on my mail server 2. Flaky (as in really flaky) WiFi in the hotel I am currently staying in

Both of these are a big problem. Network errors should not cause problems with filter definitions and deleting the targets is a really bad idea. I'm okay with having to rerun the filters, but not having to spend minutes to hours repairing the filter rules.

My Apple desktop has been compromised by malware on my Firefox browser. HELP! Do I need to erase the history? Please respond asap: [edited] on 7.20.24 Thank you, Kat Franck

Thanks for your help

I'm a long time Thunderbird user and can usually find a solution to any problem. This one has got me stumped though.

After a recent upgrade my message pane lost the header with name, date, subject, attachement, etc. and now I have one that looks like the attached .

The other three machines I have Thunderbird on displays the message pane like I've always had, so don't understand how it could be different.

As with all my machines, I run Debian 12 bookworm

On this laptop there are no extensions in Thunderbird

Hi, I have a disaster situation. I backed up my profile and then I wiped my computer running Ubuntu 20.04. I replaced it with Ubuntu 24.04. Now my profile seems to not be compatible with the Firefox installation on Ubuntu 24.04.

I followed this official instructions: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I put my old profile in the ~/snap/firefox/common/.mozilla/firefox/ folder and I set the correct values in profiles.ini. But sadly when I start Firefox all my passwords, extensions and history are not there. I lost everything.

I'm super desperate. Please tell me I can fix this somehow. Why is the official documentation lying?

Mozilla Firefox browser I am using on my kali linux but in just 5 min showing pop-up (mozilla crash reporter) then laptop will be stuck display not showing properly and laptop can't start/on. How's the problem occurs? Show me solutions

I’m a new user, using Thunderbird v. 115.13.0 (64-bit), running under Windows 10. If you can help me with the following problem, I’ll be grateful.

I added three already-existing Gmail accounts to Thunderbird using IMAP, and everything was working fine. But when a week later I added a fourth account (once again with IMAP) -- not a gmail.com account this time, but one hosted by Gmail -- Thunderbird did strange things with the downloading of all the messages. It seemed at first to be working fine: downloading first all the message headers, then the messages in the Inbox, then those in the All Mail folder and in various other folders. I began using the new account, and everything seemed good.

But later on it started downloading all the Inbox messages again (only for this new account), but this time progressively more slowly. In fact, it slowed Thunderbird down so much that it became unusable.

I quit Thunderbird and restarted, but that didn’t help: It began once again to download inbox messages, very slowly, making Thunderbird once again unusably slow.

At this point I deleted the new account (including all the message data), then added it once again. But I ran into the same problem.

The Inbox in Gmail has about 37,000 messages, and the All Mail folder, about 47,000. There are no messages in the Trash.

Thanks very much for any help you can give me.

All the best, Alan

Dear All,

I have a a sender that his email address is from same email domain with mine. Initially was able to receive messages from his side without any issues. Last week I observed that all messages received from this sender move to spam folder. I have already marked sender as not junk, add sender address to my personal address book and supposedly Thunderbird will not mark message as junk if is in your personal address book, I have also reset Junk training data. However although sender emails marked as not junk and moved to inbox after short time return to spam folder. Is it something that I am missing? FYI I have already search for a solution but nothing worked. Thanks in advance.

Hi Suddenly my email doesn't work.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.earthscapes.com.au failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I logged into my account because my passwords are not coming up and I used to have a 175 + passwords saved and now I only have 35 I've never erased them or reset my Firefox Mozilla account just wondering how I can go about retrieving my information that has been lost

For the past week links i click on will randomly not open in the tab nor will it be able to refresh(its greyed out), I'll have to close the tab and click again and it will usually load that time.

I have already cleared the cache and cookies, refreshed AND re-installed Firefox and this problem is still occurring.

FireFox 128.0 (64-bit) is back to being a memory hog until everything slows to a crawl. Some releases were better and some are worse. I like FireFox but I am having a hard time getting my work done. Switching between different items slows to a crawl.

i am moving my accounts from outlook 2007 to Tb slowly doing one account at a time, making sure it all works, then moving on the the next account, i have already moved my hotmail.com & outlook.com emails accounts to TB successfully and all the inbox, sent and draft emails also went to TB with ease.

I now have 2 bigpond accounts i want to move to TB from outlook 2007, i am only going to move one at a time and once one is fully working , ill move the other one. So now i am trying to move one of my bigpond.com email accounts to TB, the account moved over ok, but its not bringing over any of my inbox, sent, draft, or other folders with it at all.

the bigpond account in TB works for new messages in and out, but none of my emails previous and older emails from outlook came with it. i have removed the account twice and still same issue. there was a warning or something that popped up during the first time i tried this with bringing the bigpond over to TB, cant remember what it said, but something along the lines of bigpond isnt trusted or veryifed certificate. i cant really recall. but maybe that is why. i copied the same settings from outlook 2007 to TB, i even tried setting them to pop for one try and them imap the next try, i still dont know.

is there a way to find the log warning message any where on TB as to what happen during the first try of adding the bipond account, maybe that will help you guys narrow down the issue. As that warning does not come up any more when i remove and try to add the account again, it just happened the first time. i though if hotmail can work easily ( being so old ) then bigpond should definitely have no issues. maybe its a pop or Imap issue, i dont know ???

I have had my laptop for years, and I have used firefox for years. Roughly, in the last 2-4 months, all the sudden, opening up new youtube webpages, tabs, videos, takes a while, 5-20sec to fully load a new page, and when I open a new youtube tab, my laptop fan starts spinning loudly, for ~20-30seconds. Once the page is loaded its fine again. Basically opening up a youtube page is slow, and its acting like its same as playing a modern video game on my computer which is ridiculous. I have edge installed, although I rarely use it, and it does not have this problem at all, its fast, and laptop fan does not spin.
