When I open Thunderbird (Mozilla), my files are not current. In other words, the most recent emails, probably since the last time I used Thunderbird, in my file folders are missing. I have tried changing the server settings but I think they are correct. Please be patient with me, I am unfamiliar with all the terminology, etc. Also, when I first enter Thunderbird, it does not recognize my password. A window opens with the message "Login to server imap.postoffice.net with username john.fn@usa.net failed." That message also appears when I click on Get Messages. Thanks for any help.

I exported my profile to an external drive, then reset my Windows 11 PC. The resulting file is a zip file. When I import, the import starts, then stalls and gives an error. The error log is incomprehensible to me. How can I not lose my local folders and messages? I tried unzipping and importing that folder, but another error. I need help! Ideas? Thanks.

Image of the error attached.

I am now getting a spinning wheel with annoying frequency while using/trying to use Thunderbird on my MacBook Air 2017 running Monterey. Everything was fine for the first 6-9 months, but over recent months the spinning wheel has appeared more and more frequently while I'm trying to read mail, answer mail, scroll through messages, etc., etc. Now it comes up every few minutes and delays me doing anything for about 15-30 seconds at a time. It's really frustrating. I recently ran Onyx, which was designed to clear cache, etc and make everything run smoothly. But the only program it required me to quit before it started was Thunderbird. Is there some cache or something I need to clear on a (semi-) regular basis to keep it working at a reasonable speed without this godforsaken spinning wheel interrupting everything? Thanks for any/all your help.

Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

For some reason, I am getting message that the Certificate for server is not valid (etc.). I can not get or send my emails as of this morning. Is there something I can do to resolve this issue?

Since the recent update to Firefox 131, I can no longer use the Billpay option of my TD Bank account. I am able to log into my account without any problems and use all of the options except for Billpay. I want to add that I know I am not alone with this problem as I have seen several others with the same problem but with different banks. It is the Billpay option which no longer works.

As I said, the bank site is fine until I click on "Billpay", Then I get this: begin quote: "Why can't I access Bill Pay?

I have disabled uBlock Origin, Enhanced Tracking, tried Private Mode, Troubleshooting Mode to no avail.

I have also cleared cookies & data. This appears specific to v131. Any suggestions??

This is a continuation of a problem I reported earlier... https://support.mozilla.org/en-US/questions/1442170

Updating to version 115.9 did not solve the problem. Today I updated to 115.10.1 and the problem persists. Thunderbird is also recommending that I update to version 116, but I don't even see that listed on the Mozilla web page for the change logs.

Thunderbird 115.10.1, Mac OS 10.13.6, iMac 20-in Early 2008 model.

I can open Thunderbird and check mail in multiple accounts. If I close the Thunderbird window (but leave the app running), CPU usage will eventually jump up to more than 100%. It does not happen right away, but could take 10 minutes or so. Currently it is at 115% processor usage. If I open the Thunderbird window again, the processor usage drops to under 8%, then drops again to below 0.4%.

HI, I have TBird 102.15.1 64Bit installed on several different PCs and laptops. On my main Laptop I checked the Roaming\Thunderbird folder properties and found the following: Size on Disk: 35.8 GB Contains 253,172 files and 1,533 Folders. Is their anyway I can reduce the size? My TBird seems to be running slowly and occasionally stalls. I do not want to switch back to Outlook client program, I am not a Microsoft supporter. I do know I could move mail to local folders but would that mean I could only access them from one machine? Thanks.

I get a message like this every time I start Thunderbird. The topic came up last year but the conclusion was along the lines of "...this problem will be fixed in version 128" but it was never clear whether or not the User followed Mozilla's support replies or what they had to do to clear the email message from Thunderbird. .....Well I'm running version 128.1.1esr and the problem still exists.

My questions:

1. What is Thunderbird trying to do? Compact individual email files? Compae from ct the whole Thunderbird Profiles folder?

2. Is the problem the size of the Profiles folder or the overall size of the hard drive the Profiles folder resides on? What is the Hard/solidstate drive is the maximum?

3. Is the problem related to the amount of Free Space left on the Hard/solidstate drive or is the issue the number of individual files?

4. Is the issue related to the number of Thunderbird files and/or folders OR is it related to the total number of files and/or folders on the hard drive?

5. Is there a limit to the number of sub-folder levels that Thunderbird can navigate?

Thank you.

I currently use firefox 133 (32 bit) on Windows 11. Every time my router resets (either due to power outage or xfinity server outage) firefox fails to connect to multiple websites after internet service resumes, for example, I cant get to twitter.com (x.com) or even the mozilla support page while on firefox. Screenshots of the error and associated stuff are in the attachments. Firefox currently can't even check for updates.

All the webpages that do not work firefox due to the issues highlighted in the screenshots load perfectly fine in other browsers like chrome and edge. These issues in firefox go away after a couple days without any intervention which I explains how I was able to use firefox for these webpages prior to my last network outage and have still not been able to solve this post network-outage issue.

Things I have tried so far: - Disabling proxy in firefox: Did not work so I re-enabled it since that is how it was before the issues happened. - Re-install firefox 133: Downloaded an installer from chrome to do this but this also did not fix the issue. Note that I first downloaded the mini installer which downloads files as part of the installation and that also failed to connect to mozilla. So I downloaded the full installer. - Cleared cookies and data: did not work - DNS over HTTPS: Swicthed it off, did it did not work, so I switched back to the default setting. - Logged in to the router from firefox using the router's IP address: Not sure why I thought this would work but it did not.

Any help would be appreciated to solve this issue once and for all.

I have just updated to Firefox v134 stable release on Android and now when I log into github.com, the webpage is glitching and not being rendered properly. The avatars on github look torn and they are blinking when I scroll up and down. This is occurring with current Firefox stable, beta, and nightly releases on Android.

My device is a Samsung T813 tablet running Android Nougat (Android 7.1).

I should also mention that Firefox v134 on Android is also showing UI glitches when viewing the settings in certain extensions, like FoxyProxy. Although, I have also done a clean install of Firefox v134 with no extensions installed and the webpages like github and still showing the rendering problems mentioned above.

For the past 2 weeks Firefox has been repeatedly crashing soon after going on to certain sites or trying to apply my 2FA authenticator add-on.

Suddenly there's a screen shudder and a new window opens, inviting me to submit a crash report. See attached image.

I do not believe that this is down to Ubuntu 24.04 upgrade done at end of August.

But it's enough for me to largely go over to Chromium and Firefox Dev Ed.

If Mozilla don't act on this crashing I can see its market being lost fairly fast.

Today I was no longer able to stream movies on Amazon Prime or Youtube. I watch Amazon movies most nights, watched last night. Tonight I got a message when I tried to continue watching a tv series on Amazon that I've watched for weeks. It said I had to update Firefox and told me how, but when I went thru the process Firefox said it was up to date. On Youtube I got an error msg. 99,999 . What is happening?

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

Been using Firefox since the 90s and been on Mac since 2000s. This problem has been happening for about a year, throughout three macbooks (my old one, a temp one, and my new one) and multiple Firefox updates. I'm always updated and always clear cookies daily.

The failure to move bookmarks I can overcome by rebooting Firefox with a Forced Quit. If I only have to do this every few weeks, then no biggy reinserting all my passwords for all the different sites I use (and no, I don't want to use password managers, I don't trust them)

Today it happened within hours of Force Quitting Firefox, this is too much!!!

The only reason I didn't report this problem earlier is I simply expected an eventual newer version of Firefox to fix this bug.

Firefox 133.0

Normal behaviour: click-drag bookmark within bookmark menu pull-down to position where I want bookmark Failure behaviour: click-drag fails to move bookmark, until I reboot Firefox, then it works again

the past 4 producers have told me they cant hear me on google video chat (https://meet.google.com/) i'm on firefox. it worked fine forever, then no one could hear me and i reported it a bunch to google and firefox because it was clearly a firefox issue. someone on their end fixed it. it was working for a while. now its back to people not being able to hear me again when its not a me problem. i keep reporting it and its not being fixed. how do i escalate this? why does this keep having every few months?

zero issues on google chrome browser while video chatting. zero issues on zoom. its firefox's google videochat that people cant hear me. feels like a repeat issue of what happened months ago when the issue wasnt with me. please fix this again

Thunderbird, quite suddenly, stopped getting my email; Both on my account and my wife's account at the same ISP. I spent more than two hours on the phone with the ISPs help line trying to resolve this issue. They also use Thunderbird at their help desk, and the agent I talked to was familiar with your program. She (the agent) was not able to replicate the issue on their system. We then tried to set up a NEW email account. I carefully entered all the info needed for a new account, following instructions from the agent, then hit the 'Test' button. I got the following message onscreen: "THUNDERBIRD FAILED TO FIND SETTINGS FOR YOUR EMAIL ACCOUNT" The answer to the original issue suddenly became very clear - Thunderbird cannot, or refuses to, connect with the email server, therefore NO EMAIL. We tried everything in her toolkit to resolve the problem to no avail. We finally tried UNINSTALLING Thunderbird (and the Maintaince program). Once Uninstalled, I used the Registry Tool on CCleaner to remove any entries in the registry referring to Thunderbird (there were several), then restarted my computer. I then downloaded and installed a totally NEW Thunderbird program. When I ran the Thunderbird again, I found all my account(s) info was still present, and Thunderbird was still unable to find the server. I'm at my wits end trying to resolve this issue, and REALLY HATE to go back to Microsoft OUTLOOK to get my email. Anybody got any ideas??? Any help would be greatly appreciated. (Signed) Proteus

I think it started to happen with Version 128.9.0esr | Released April 1, 2025. It is very simple to reproduce: 1. Start TB. 2. TB downloads new messages and continues to do it every 1 minute according to the setting. 3. In 10 to 20 minutes, it hangs. I have to force it to close and then restart it to check my email.

I believe it started to happen yesterday.

Is anyone else experiencing this?

I'm having much difficulty in attaching a article I see to Facebook. Its possible the problem may be I'm not using the right instruction on the Firefox options when I right click the article I want to attach to Facebook. Some of those options are, Save link as, Copy link, when I right click for options. Can someone explain what is the right option to use? And, how do I proceed once I choose the correct option to make that attachment to a Facebook message I'm replying to? There are times a picture of the article will attach to the Facebook message, but the text that is associated with the attachment will not appear? Can someone please help? Thank you.

I'm running Sequoia 15.1.1 on an M1 Mac Mini. Never had problems before. TB 128.6 0 esr.

As soon as it opens it crashes.

I have a lot of unopened files in a pop mailbox, going to try and remove them.

It seems to still work on my iPhone. Any ideas?

I M get this working. I'm in a panic. Please help.
