I was having problems with my chromebook. when I start my chromebook and i click on the thunderbird icon it doesn't open ! I have restored my chrombook and reinstalled thunderbird again but the problem is still there. The only way to access thunderbird is to open linux and type in thunderbird and then i have access to thunderbird once I turn off my chromebook and then reopen it once again thunderbird is not working !

The Firefox Browser crashed three four times last week. Mozzila Support team after study, gave a comment that RAM capacity is Low( 4 GB in my case , laptop). Does it sound OK? Why it does not happen with Chrome or Microsoft One edge Browser? I asked this to Google Gemini. The answer is as given below: Yes, the Mozilla Support team’s explanation sounds entirely accurate.A capacity of 4 GB RAM is extremely low for a modern laptop running an operating system like Windows 10 or 11 alongside modern web applications. The operating system itself routinely consumes 2 GB to 2.5 GB of RAM just to keep your computer running, leaving very little leftover memory for heavy multitasking. Both Google Chrome and Microsoft Edge use built-in "efficiency modes" and aggressive tab-sleeping algorithms. When your computer begins running out of RAM, Chrome and Edge will silently put inactive tabs to "sleep" to free up memory before the browser crashes. [1] (https://www.superchargebrowser.com/library/firefox-vs-chrome-ram-usage-2026/) Good Solutions to Fix the Crashes- 1. Software Adjustments (Free & Immediate)If you want to keep using Firefox smoothly on 4 GB of RAM, you need to minimize its memory footprint:Reduce Firefox's Content Process Limit: By default, Firefox uses multiple processes for performance. You can lower this to restrict its memory use:Type about:config in the Firefox address bar and press Enter.Accept the warning.Search for dom.ipc.processCount.Double-click it and change the value to 1 or 2. This forces Firefox to use fewer system resources. [1] (https://en.wikipedia.org/wiki/Firefox)Enable Memory Minimization: If the browser starts slowing down, type about:memory in the address bar and click the Minimize memory usage button under the Free memory section.Use a Tab Suspender Extension: Install a lightweight add-on like Auto Tab Discard from the Firefox Add-ons store. It mimics Chrome's behavior by automatically putting background tabs to sleep.Turn Off Hardware Acceleration: Sometimes, your computer's integrated graphics conflict with Firefox under low memory conditions. Go to Firefox Settings > type "hardware" in the search box > uncheck Use recommended performance settings > uncheck Use hardware acceleration when available.

This Method I tried, but did not work-Firefox to use fewer system resources. Can you suggest how to reduce or minimize its memory footprint?

I mostly watch YouTube channels on Firefox on my laptop, but recently have had to change over to Microsoft Edge browser to watch YouTube. The reason is that during a channel stream, when an ad wants to play, YouTube and Firefox freeze and the only way to exit the screen is to either attempt to close YouTube or even open Task Manager to shut down all instances of the Firefox software. Firefox is by far my preferred browser and I'm frustrated that it is unusable in its current state. I tried to uninstall and reinstall, but this did not work. Thank you in advance for your help.

Since 3rd September 2026 Thunderbird opens a system integration window and then goes to not responding. I cannot access my emails through this software at all at the moment as there's no way past his pop up. Version 153.1.1, Windows 11 Home.

thunderbird startet nicht/ will Anmeldeinformationen für eines meiner yahoo-email-Konten in separatem Fenster / hängt komplett fest / keine Rückmeldung / kein Zugriff auf gar nichts...

Running Windows 10 (have extended security updates). Starting at version 153.0 Firefox hangs (spinning cursor) until Windows realizes it is not responding and lets me stop the program. Seems to be independent of the website (even happened on a Mozilla page). Have tried a couple of 153.xx updates and also 154 but behaves the same. On a Dell Inspiron 7570:

Processor Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz 1.99 GHz Installed RAM 8.00 GB (7.84 GB usable) Storage 932 GB HDD ST1000LX015-1U7172 Graphics Card NVIDIA GeForce 940MX (4 GB), Intel(R) UHD Graphics 620 (128 MB) Device ID 8036C0FE-3179-4D8D-8C72-672ED25B0ABA Product ID 00325-96206-88905-AAOEM System Type 64-bit operating system, x64-based processor Pen and touch Pen and touch support with 10 touch points

Hi, Firstly, thank you for all your services.

When working in a tab, Whatsapp, Youtube, or even Buzilla when I want to report this, the tab just crash's. Sometimes I can restore it immediately, but other times if I click on "Restore this tab" repeatedly, the whole window crash's!

Starting today, Thunderbird freezes during the "loading messages" process. I get a Windows hourglass and Windows tells me Thunderbird is "not responding."

Task Manager shows TB running but not taking up very many CPU cycles.

I suspect a damaged database, but what do I know?

Each of the tabs above is an email/message that was open the last time I ran TB.

I have no control over TB as it 'spins.'

I cannot find my TB version because TB is frozen. But it is fairly recent.

I need help.

Hi, I have been a Thunderbird user for many years and have over 16,000 emails in my account.

Today when I launched TB it comes up with blank screen with No Response on the top left. See screen shot image upload.

I have tried launching with Thunderbird -P and it only shows default account named default.

- other places show 3 accounts with one having -release

--Users\myuserID\local\Thunderbird\profiles:

   9qflpwnsdefault
   8593y64.default-release
   fsomy6as.default

--Users\myuserID\AppData\Roaming\profiles\ shows the 3 listed above.

I have tried launching Windows 11 in Safe Mode, same issue. I have tried the Troubleshoot Tool with same result.

Any ideas on how I can get TB to load correctly and show me my emails?

Please let me know if you need additional information.

thank you, George

Hello, we have a DLL product that is injected into Firefox, and it generally works properly. However, from time to time, we encounter crashes like this in individual tabs.

Could you please help us understand what might be causing these crashes?

I’m also sharing the crash report for reference.

Crash ID: `52627b3c-6243-4f14-8f61-e51090260831`

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.

Dear Firefox Team,

My tablet (Lenovo P11 running Android 11) crashes completely (as in completely freezes not allowing me to do anything else), when opening certain websites (1 out of 3 times) including but not limited to instagram.com profile pages. I believe crash reports were never sent or could be sent, as my entire device has crashed.

As for more I formation, I had these extensions running: 1. U-Block origin 2. ClearURLs 3. Dark Reader 4. Video Background Play Fix 5. Chrome Mask (but was deactivated mode)

This crash happened 5 times now (out of the 10 to 15times I have opened these sites).

I have for the time being installed Fennec (with only Ublock, clearurls extensions running). There has been no crash yet.

I would like to confirm why those crashes were caused. Here are some of the reason I believe: 1. I am using an old Android device. 2. I was using multiple extensions incompatible with the webpage. 3. Combination of both.

If there could be other reasons please do state them.

Best reagrds, Sentry GA

Running Thunderbird 140.14.0esr under Linux on a Chromebook. Have tried several times to move messages from Inbox to other folders and each time TB shuts down. When I restart it has an extra blank tab. I am able to move items using the Move To menu but that's tedious. It appears there was an update 18 August but the issue just started today. There have also been recent updates to Chrome but I've done all the shut downs/restarts called for.

Mozilla Thunderbird stopped responding, tried to shut down, restart, uninstall and install - nothing helps Still opens the window, but no messages white backgoround and (Not Responding)

Since upgrading my MacBook Pro to Tahoe 26.6.2, I notice that Thunderbird continually crashes when I open it. I've tried closing Thunderbird after each check of email, and I think that helps (at least a little).
