After Windows installed an update in the middle of the night I can't open Thunderbird and I've tried uninstalling it and reinstalling with success.

It says: Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window.

I've rebooted the PC, shut down the PC, ended the task and still nothing. It seem that Thunderbird didn't shut down correctly and the system still thinks that it's open and running. Anyone know how I can fix this issue?

Thanks,

Gregg

Hello. The browser will start fine and run for most of the day. I haven't made any known changes to the PC. At some point the browser will crash for all tabs and all windows. Any attempt to refresh goes to the screen as seen in the attached image. The "Restore This Tab" button does not work. I have to close all Firefox windows. Then the browser will work again.

I'm using an Alien computer. Windows 11. Everything is up to date. Firefox version 145.0.2 (64-bit)

Thank you.

TODAY'S (NEW-ish) ISSUE: - Multiple times per day I Click the Yellow button Top Left Bar to shrink and put App in dock to open again later. When I re-Large FireFox shows EMPTY FireFox Bar like I "Quit". Each time need to go to History and RE-OPEN ALL TABS??????

1. 2 within THIS text box just now, I highlighted the words: "Today's Issue" and clicked BOLD - instead it added a 2nd set of parenthesis???? WTF?

Browser is open all day. Always multiple tabs open/signed in, Paid & non-paid Apps, Email boxes, Wix, etc, many website tabs up, I do a lot of "research" - to pay my $rent and/or live my life using this "tool". Is my typical behavior. IN THE MIDDLE OF DOING WORK - I need to fix re-load Firefox again and again. . . Interrupted, distracted, observe, deal with so many Tech failures every day from ALL brands, I am struggling to keep my "life" functioning.

470+ issues/articles counted in the 11 subject boxes - in HELP section. FOUR HUNDRED-SEVENTY.

Thank you to "Volunteers" responding to help / issues!! Do you do any MENTAL help volunteering? kc

Hello,

Since yesterday Firefox has been crashing within several minutes of opening the app. It initially appears to load fine, then begins to stutter and lag around 30 seconds in. At this point scrolling usually begins to stop and the Android UI locks up (can't go to home screen, etc). In addition the bottom Android bar usually flickers on and off.

The crash occurs whether a page is loading or not. It also doesn't matter which screen I'm on (the crash still happens if stay on the new tab page, load a new page, open the settings and hold there, etc). It also occurs when Twitter loads Firefox as its browser.

In most cases the app crashes with no crash log saved to about:crashes. However, around 1 in 10 attempts a crash log is generated. Here are crash stats from the two crashes that made it to

• First Report: android.content.res.Resources$NotFoundException
• Native crash - unhandleable OOM

Actions I have taken to try and fix the issue:

• Check for Firefox and Android updates (both versions were current)
• Clear app cache through Android system settings
• Restart phone
• Disable all extensions
• Close all tabs

I'm not certain this is the correct forum for this report. If posting here was in error please direct me to the correct bug reporting platform.

Thanks

For whatever reason every time 'Firefox' browser goes down my email shuts down also. This did not happen prior to trashcan Win!!(recently installed). It's a pain in the ass having to reactivate 'Firefox' then contact my email server to reactivate my email service. Any assist is appreciated. TangoYankee in advance.

With thunderbird version 140.4.0esr (64-Bit) on Linux functions to print e-mails or pdf documents is no longer working. When trying to print an email or a pdf document thunderbird starts looping and you need to stop thunderbird from outside with a kill command.

Since around version 96 it seemed some new core changes made to how ff operates. any one care to share what the "big changes" were around that version rollout tldr?

since ver 96 ff became secondary browser. Using to test/isolate issues w/chromium (sigh). Now since ver 132 profile manager opens browser for correct profile everything looks good then 20seconds later ff crashes eorror: Exiting due to channel error

Inspiringly i see this forum is being used still so thought i would see if anyone has ideas what changes btwn ver 96/101 and 132 which may cause this new issue, maybe i can backout the changes and get back to using ff as a secondary backup again ....

IDK about anyone else but i LOOOOONG for the ole days when ff was a daily driver option on linux

I'm in Troubleshoot mode, no extensions running, and tabs are crashing again. Here are crash report #s for today:

Is it coincidence that this is happening on my Windows 10 machine since MS support for Win10 officially stopped? Gosh, I just don't know! grar grar grar

We are experiencing an ongoing issue with Firefox that persists even after performing the following troubleshooting steps: - Uninstalled Firefox completely. - Removed all browser add-ons and extensions. - Reinstalled the latest version of Firefox. Despite these steps, the issue still occurs: Browser crashes, pages not loading, extension not working. Additional Information: - Operating System: Windows 11 Pro - Firefox Version: 145.0.1 - Error Message:

We would appreciate guidance on resolving this problem, as standard troubleshooting has not resolved it.

Thank you in advance for your assistance. Kind regards, Edward

Using 140.2.1esr (64-bit) on Win, laptop has plenty of disk space free. When writing a long-ish message, I want to stop and think, so I do Ctrl S to Save... Sometimes works fine. Sometimes Thunderbird hangs and does not save, so I lose everything I wrote, very frustrating. Problem happened off and on during many weeks. I cannot replicate the problem on demand. Shut down- restart did not help. Any help will be much appreciated thanks.

Thunderbird 145.0 (64 bit) with Windows 11 Pro.

In the message editor window, new message or reply or forward, when I want to insert a hyperlink using either CTRL+K or via the Insert menu, a popup window to insert the link into does not appear, and the write windows hangs. Becomes unresponsive. The only way to close it is by ending the task in Task Manager. I notice a crash helper in the Thunderbird group in Task Manager. Everything is on 0% CPU though.

What went on before this is that I modified the property editor.link_color in the config editor (because links are not readable in dark mode, but that's a different story). I then did reset it to default and restarted TB, then pc and TB, that did not help.

In troubleshooting mode, there is no problem. In normal mode, I deleted the only plugin I had (a theme) I cleared cache, refreshed Thunderbird, to no avail. It's not set up to generate crash reports yet.

I have TB on another machine (W10 Pro), I can copy my profile folder over quite easily.

Any suggestions please?

(I'm on Central European time, it may be a day or so before I respond to replies from the US.)

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

For about 2 weeks, EVERY time I try to write an email, after typing a few lines or so, the whole window 'grays out' and becomes UN-responsive. I get no error message. Waiting for it to respond doesn't work and I have to close out and re-start Thunderbird. Sometimes Thunderbird will have saved some portion of my email in my 'Drafts' folder, but not reliably, so I have to frequently 'Control + S' - save it to avoid having to re-type the entire message again. Troubleshoot Mode doesn't help, nor does clearing the cache. I've been hoping an update would come up that would solve this, either from Thunderbird or Windows (11), but not so far. Please tell me how I should resolve this - I have used Thunderbird for years (and regularly contribute too) and don't want to have to change to different email client.

Confused. Version 144.0.1 | Released October 16, 2025 Says 32 bit. I thought I downloaded 64 bit.

Problem: Freezes when I click anywhere on TBird desktop

How do I address the freezing problem?

Thanks Robert

My computer glitched today. Before that I could bring up Firefox and all pages would restore.

Now Firefox comes up and shows one page like a new page. One tab and no other pages appear I had several open when the incident occurred.

Now I get the one page. From the Task Manager window I see the one page and "crashhelper" followed by several Firefox icons (all appearing to be using memory) but none of them are displaying any pages on my display.

I made a screen shot and enclosed below

My question is about lack of functionality (Topic) but it is not listed in the selections above!

I selected Accessibility because I cannot access any of the tasks shown below the "crashhelper" because none of these pages are displyed
