I was using thunderbird. I accidentally hit the sort by star right above the email list. The application crashed closed. When I reopen it, it immediately crash closes. I can't even get an pointer arrow for long enough to exit myself.

On window 10. Thunderbird was up to date.

Tried - restarting computer. Signing out of TB in the crash report box. Can't get into safe mode.

Hello. I'm getting constant crashes on a new installation of Thunderbird on a new PC. It seems to happen when downloading emails, of which we have tens of thousands, and it seems to crash every few seconds or minutes. I tried reinstalling, and running in safe mode and disabling addons. I tried deleting the account and recreating it. I tried deleting the profile folder and recreating it. We have 4 email accounts on that machine (we have a dozen in total) but as TB seemed to be struggling I deleted all of them and recreated only 1, which made no difference. Apart from that the PC seems to be normal and does not report any errors. We have a dozen other PCs all running Thunderbird with the same accounts and with the same settings, none of which show any problems. The crash reports (I have loads of them) all seem to show EXCEPTION_ACCESS_VIOLATION_READ This is the ID of the most recent one: 4e9ad970-189e-41e9-9399-8db820180222

Thanks in advance for any help.

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

Changed IMAP to POP. Now I have errors, such as "msgFilterRules...Conflict.dat. Deleted all my message filters, but this message STILL pops up.

I also have popstate-1.dat & popstate-2.dat 2 Junk folders, 2 Outboxes..

I have screwed this up somehow....

delivery format auto-detect does not auto-change to HTML when an image/picture is pasted into email body

problem was present in an early version of TB (sry don't remember which) then was fixed but has reoccurred on 38.4.0 (dunno if it begun at this version, just realized 38.4.0 has this issue again)

if delivery format option set to HTLM then it works (pasted image is sent)

see attached screen shots

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

Win8.1 using Tbird 24.5.0. Download of emails became intermittent in mid-May. As of 6/4, none can be downloaded. No problem sending emails. I have a POP3 account with Earthlink. I started Tbird in safe mode via Help > Restart with ad-ons disabled.

The status bar at the bottom stated that I was connected to pop.earthlink.net. Then it stated that is was 'Downloading message 1 of 116'. After a while with no messages coming in, it stated 'No messages to download'. It never said downloading message 2, so I don't think the messages went somewhere unknown.

This is the situation with my Windows firewall disabled and with my G Data antivirus disabled. I've tried various other things after reading that others are having a similar problem. Earthlink support verifies that I have the right setup. I uninstalled Tbird and reinstalled. I removed the account and added a new one -- and lost my saved emails until I went to my backup. Someone mentioned a ad blocker. I have one on Chrome from Adblock Plus; I don't see how that would affect Thunderbird.

What now? Thanks, Bruce

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

In my list of Inbox Unified Folders (13 of them), one folder in particular (the second one) is sometimes there, then at some point later is gone. It's still in the 'All Folders' list, but not in the Unified folders list. If I kill TB and restart, then it's back. I have no idea what ops might cause it to vanish. Any idea what's causing it to vanish or what I can look at?

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

I installed Firefox years ago. This morning, when I click on the browser icon, I get this message: Error platform '127.0.2' is not compatible with minVersion>= 127.0.1 maxVersion<= 127.0.1

What is going on? The browser updates itself so I don't do anything. But now, it doesn't work. I use an alternate browser to send this message to you.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Dear Support Team,

After updating to last Mozilla Firefox version (126.0.1) all my ngx-datatable tables are overlapping all rows over the first one even if the entire height of the table is correct calculated.

This is a blocking point. I need assistance urgently.

Firefox 115.12esr slow to startup takes up to 10 second to load the first time now Firefox was fine in version 112.esr. to bad Firefox forces updates, even when the update make Firefox worse. https://snipboard.io/QF0ERT.jpg of course it works faster without extensions, that does not mean anything. I would reinstall the older version but Mozilla fixed so we cannot. I do not have time to reinstall all the extension so I am left with a useless Firefox. To bad Firefox does not allow reinstall of extension automatically, a reset of Firefox would also make Firefox useless; I am at a loss to how to continue to support Mozilla and not switch to another browser?

My ISP, Cox, sent me a message that I have to change my POP server settings from:

port 110, Connection security: None, and Authentication method: Password, transmitted insecurely

to:

port 995, Connection security: SSL/TLS, and Authentication method: normal password

When I do this Thunderbird will not retrieve any new messages. The same changes work ok on two android devices, so I can see from them that there are new emails for Thunderbird to get, it's just not getting them. I tried changing one of my accounts back to the port 110 settings and that account now works again.

I tried contacting Cox about it but they stated that they don't support Thunderbird and referred me here.

I'm on Thunderbird 52.5.2 32 bit.

I've read a few historic suggestions about how to resolve this, but I haven't been comfortable with what solutions were suggested as they didn't seem to comprehensively answer the questions, I'm afraid.

Until this morning's attempts to resolve the "running out of disk space" warnings, I had two mail accounts on Thunderbird - my old Hotmail account and my new personal domain based account. Both accounts had old emails (3/4 years' worth) filed locally on my PC pending my satisfaction that the new mail account was working satisfactorily. To try and resolve the storage issue, I deleted all the locally stored emails from my Hotmail account from within Thunderbird, then deleted the Hotmail account, and restarted both my PC and Thunderbird.

The expected reduction on space occupied by the .thunderbird folder didn't materialise - at all.

How can I get back the space so I can continue working, please?

My default font is Calibri. However when writing messages the font often changes to Times New Roman. This happens especially after indenting a paragraph. It also often happens right from the start when replying to emails.

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

Not used Thunderbird for about a week as was away. On my return I am now getting duplicate downloads every-time I open Thunderbird on my desktop using Windows 10. I am on Thunderbird version 115.12.2. I have been using Thunderbird for a long time and this is the first time this happened.

I recreated the global-message-db.sqlite indexfile, turned off my anti-virus, compacted folders but nothing solved the problem.

However I did find a similar question on this site with a solution which wasn't exactly the same but lead me to investigate the Mail folder in my profile. I see I am getting duplicate pop.gmail.com folders (pop.gmail.com, pop.gmail-1.com, pop.gmail-2.com, etc.). I guess that is probably connected to the problem.

When I open Thunderbird I also get the message 'Connection to server pop.gmail.com was reset'.

Any help would be appreciated. I didn't want to delete any pop.gmail.com folders without expert advice.

Thank-you in advance.
