I became a THunderbird user recently to help me transfer e-mails from one system (e-mails sent to my e-mail address being collected by Gmail using POP3) - I have a gmail.com address too which shows all the e-mails in the same Inbox. Google are withdrawing support for Pop3. I am moving to Hostinger which happily collects and displays all my emails on its Webmail service. Thunderbird is a great tool for moving e-mails fro Inbox (and al other folders) from the Gmail to Hostinger. But yesterday it crashed and wouldn't restart = white windows says at the top 'not responding = and Windows Task Manager shows me Thunderbird still seems to be talking to one of my accounts and has 6 other tasks open. I stopped those tasks and closed Task Manager. I have uninstalled and re-installed but it comes back with the same symptoms and same tasks running. How do I stop this and get it back properly again

My Thunderbird crash whenever I tried to "save as" an email, save the attachment of an email, attach a file to an outgoing email.

Every time I did the mentioned, Thunderbird prompts the normal window of my laptop's folders, but it disappear in a second with the Thunderbird crash and quit.

This situation happened after I installed MS365 on my laptop.

I did try the below: 1. Reset attachment directory - mail.compose.attach.dir 2. Run in trouble shooting mode 3. Repair folder index 4. Clear cache

Anyone can help please?

Using Ubuntu 24.04.3 LTS with Firefox 147.0.3 (64-bit)

Firefox crashes when trying to access any banking website. Can get to the login page, but then firefox crashes and a crash report window comes up with quit or restart option. This has been going on since shortly after upgrading from 22.04 Ubuntu. Started with Firefox 147.0.1 and after upgrading to 147.0.3 did not fix the issue.

Started Firefox in Troubleshoot Mode and that works when going to the bank login page. Using Standard Theme and only extensions Windscribe - Free Proxy and Ad Blocker and DuckDuckGo. Disabled both and same result of crashing om bank log in pages.

I run Windscribe VPN through my separate subscription, but it doesn't matter if it is on or not. Banking websites (Keybank, Kinecta, Capital Group) still crash Firefox

Also crashes when trying to access Excellus BCBS log in page. Most other websites (news, sports, Amazon) are fine.

Searches on your support page yields ) results.

Please advise!!!

I tried to purchase something on Amazon. When trying to log into my Amazon account it asks to perform 2Fa on my mobile or use a pass key. But neither option responds and Firefox is completely locked up - cannot tab, select menu options etc. I have to use the Apple Mac Force Quit screen to kill it. But when I open Firefox again, the same tabs appear and it's still locked up on the Amazon screen. Cannot use Firefox at all now, forced to use Chrome. How can you reset FF. so that it just opens a new screen?

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

Hi,

At some point in the last couple of weeks, I've started running into very frequent crashes running Firefox in the Linux container on my Chromebook. It previously worked well, but is now unusable. I'm now running Firefox version 147.0.3 on Chrome version 144.0.7559.167. This is after I did a clean reinstall of Firefox using flatpak, which didn't help. It seems like it often happens when my mouse hovers over a browser tab or icon (eg account, extensions, hamburger). Other quirky display behaviour, which mayor may not related, is that videos are often not working (eg Youtube, BBC), and various browser windows (eg when selecting Manage Bookmarks, or restarting in safe mode), open a small size-reduced window. Latest crash reports below -

Thanks for any suggestions.

Thunderbird (current version) freezes each time an email is closed and when it does so, it freezes the entire computer. Computer: MacBook Pro 16"; Tahoe 26.2. The freeze last for 2-5 seconds before it releases.

Firefox not responding. I have tried everything on the Help pages. I have tried reset of everything. I have uninstalled and reinstalled from scratch. Still: when I open it: Firefox does not respond. And everything else also is very slow then. In Windows joblist I can see Firefox with 7-15 threads. One of them "not responding". I have no problems with Chrome nor Edge - W11, 16GB Ram

When inserting several larger images (JPEG, 1.4 MB, 1770x2440 px, 300 dpi) directly into the message body (i.e. not as an attachment), Thunderbird crashed and the draft of the written message was not saved.

Is there a limit to the maximum size or format of an image that can be inserted directly into the body of the message?

I am using THB release 140.6.0esr/32-bit

Hello, My firefox app stoped working today(version for androids). I uninstalled it and installed it twice but it still won't work. When I open it, it stops working after a few seconds and I recive a notification that it crashed. What should I do?

Over the past 2 or 3 weeks, I've noticed that firefox tabs are crashing more often out of nowhere.

https://crash-stats.mozilla.org/report/index/4a42f4cd-2203-40ba-a40c-616590251210#tab-details

Here's one of the links for the most recent tab crash. Other crashes pretty much were all the same. I can't read or understand this, so I was hoping someone who can is able to tell me what is wrong.

I fear that it might be hardware related, as I've had tabs also crash on Edge and on a new install of Firefox Developer Edition (which I downloaded simply to test if things crashed there as well.) I've also noticed programs like Discord & Elgato Wave Link sometimes randomly crashing as well - but I'm unsure how to pull logs for those, Firefox was the easiest.

My laptop's hardware specs are as follows:

Lenovo Legion Pro 5 - 16IRX9 Processor: Intel Core i9-14900HX (2.2GHz) Installed RAM: 32 GB GPU: GeForce RTX 4070 Laptop GPU Windows 11

If you need more information, please let me know.

Here are some previous crashes that I've reported as well:

I have been using Google Messages in Firefox for over a year, and have never had any problem until the most recent Firefox update from Linux Mint. Google Messages loads on the tab, and everything seems fine. But when I click on a conversation on the left, it crashes as it's loading the conversation.

All of my software is up to date, i.e., no new software updates are indicated in the system tray (?) on the panel. Firefox info: mint-001 - 1.0 147.0.2 (64-bit)

Hopefully this gets fixed soon, because checking my messages using my PC saves so much time.

Thank you

I've been using Firefox on Linux since it was Nautilus. Currently running EasyOS Linux Daedalus and Excalibur on different Lenovo ThinkCentre Tiny Core i3-8100t boxes and different drives: A good Samsung SSD and two good flashdrives. 32G new RAM installed on each box. I've been using these boxes for over a year. For the last month or so, ever since updating to v. 146 my tabs have been crashing like crazy! I don't normally have more than 10 tabs open at once. But now, as soon as I open a 5th tab it crashes.

I'm running Top to watch CPU and RAM usage. I see nothing unusual. I've rebooted. Disabled all add-ons and run in Troubleshoot mode. Tabs still crash. My only add-ons are uBlock Origin, Temporary Containers and Dark Mode. It happens whether I have hardware acceleration turned on or off. I don't know what else to try. Here are my most recent crash reports. I hope you can figure out the problem. Thank you so much!

NB - For the past half a year I have to sometimes right click to interact with them, anyway

Effectively, I will interact with the extension at the most basic, normal level on something that has interactive elements like a dropdown menu, or basic options.

I will click / right click on the icon and the highlight will appear, then that's it ... the browser then crashes and does not recover. :(

What's worse is that I have to Force Quit and when I restart there is no crash report to send to Moz.

I am just wondering if other Linux users have experienced similar issues.

The attached image is taken at the moment before the 'Force Quit' dialogue opens up in Debian 12 Gnome (Wayland) ...

I have Hardware Acceleration on.

I am about to start testing with it off, but I work from the browser, and do not want performance compromises. So that is (at best) a work-around, and certainly is not a fix.

I'm on version 147.0.2 (64-bit) which would appear to be from the Mozilla Firefox Debian Package mozilla-deb - 1.0 install/repo/whatever ... and the PC specs are: Processor: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Memory: 32705MB (11893MB used) Resolution: 7680x2358 pixels OpenGL Renderer: Quadro RTX 3000/PCIe/SSE2

These are my media. prefs ... but ... I doubt that it is relevant: media.ffmpeg.allow-openh264 true media.ffmpeg.customized-buffer-allocation true media.ffmpeg.disable-software-fallback false media.ffmpeg.enabled true media.ffmpeg.encoder.cpu-used 7 media.ffmpeg.encoder.enabled true media.ffmpeg.encoder.quantizer-max 35 media.ffmpeg.encoder.quantizer-min 10 media.ffmpeg.vaapi.force-surface-zero-copy 2

After successfully downloading Thunderbird several times (my browser is Firefox), the only functioning option provided is to make a donation. That is, it's telling me I must make at least a $5 donation in order to proceed to setting up a Thunderbird account. This despite clear statements on the website that donations are not required in order to use Thunderbird. There is no way to skip this step.

After closing the donate window, I'm taken to a nearly-blank screen with absolutely no functioning features on it other than a link that leads to multiple, useless articles about who knows what.

Please fix the site and advise how to proceed without further roadblocks.
