Greetings,

I've lost the ability to receive e-mail, Suddenly Thunderbird just quits on me with no warning. Apparently I can still send mail but cannot receive. This is the second time this has happened to me in as many months. How do I fix it? How do I prevent it?

Thanx

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.

Hello, I run Firefox mobile on a Motorola g stylus 5g, and although I'm aware it's a lower-end device, the constant crashes with the app is becoming infuriating. I'm on the newest version, and a large majority of these crashes occur when I'm on twitter browsing posts.

These crashes can happen a few minutes into browsing to an hour, and this issue used to never happen until the update before this one. I use a few extensions related to appearance, those being Ublock origin, dark reader, and control panel for twitter. Performance regarding being on the website has always been awful, but it's never crashed before.

In addition, the app is insistent on reverting me to tabs I had either an few hours ago to days ago, and it changes to what I currently had on screen for unexplainable reasons. I've tried resyncing tabs but this rarely solves the issue

Any advice in resolving these crashes would be appreciated. Attached is my crash log.

I Use Thunderbird on Windows 11. I changed a retention policy on a Local folder to delete messages older than 60 days. Since then Thunderbird stopped responding and has never worked since. When i open Thunderbird it immedeatley stops responding. It does not show any emails in the inbox and folders will not open. I have unistalled and reinstalled Thunderbird opened and closed in Safe mode but nothing works. Closing Thunderbird task via Task Manager does not help either.

Firefox indicated a new version was available and I installed it. After restarting the app, links will not connect and I receive this message.: Gah. Your tab just crashed. We can help!

Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

But nothing helps. I cannot reach most of the sites where I need to work.

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.
