Over the past couple of years, I will receive one or two emails that displays as a scrambled mess of characters, and sometimes one email is combined with another (the header of one mixed with the body of another). However, this morning, I received several scrambled, combined emails that I can only read if I log into my email provider/hosting company. What is going on and what can I do to stop this? I have no technical skills for going in and coding anything.

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?

Whenever I sign in to sync my browser it keeps asking me to sign in again to reconnect to sync.

I've tried reinstalling the browser, deleting the Mozilla directory in %APPDATA% and reinstalling, removing account and signing in again.

No matter what I do I keep getting asked to sign in again to reconnect even though the initial sign in was successful.

I am using latest firefox developer edition. After firefox updated automatically, I found that I lost toolbar customization settings. I reconfigured everything, but the next day when it updates I lost the settings again. It seems that there is a bug in Firefox. How can I fix this? If this is a bug, when will it be fixed?

I am using Mozilla Firefox Developers Edition for Windows 11. Recently I have encountered a problem where my bookmarks are constantly disappearing from the panel and toolbar elements are changing places (like the arrows or the reload button).

I read the support and came across three articles about problems with this. The first two were xulstore and Places.sqlite files, which I deleted and followed the instructions in the article, reset the browser settings, but nothing happened. The third article was about the profile, I went in and saw that I had two profiles, which I deleted and created a new one, completely previously removed the browser from the device. But again, nothing happened.

I think this started when I started using the built-in Windows 11 workspace feature (multiple desktops, I opened two browsers at the same time). It was after this that my bookmarks and toolbar changed in the pre-login in the application.

I would appreciate help with this issue.

Hello👋 I am using firefox developers edition on build 132.0b2 and my UI is not rendering correctly, the themes work but the objects like the bookmarks toolbar and the refresh button and the home button even some of my extensions is not loading and other things also not loading, but fortunately I know the keyboard shortcuts for these functions and they are working just fine but all the buttons are just not there My device is a Dell Latitude E7450 and it has a normal core I5 5300U so it is not an x86 arm based processor I hope that you find a solution ASAP as I am really struggling with my browser like this and btw I really love your work and the products that you give Thanks for doing the hard work! bye

I have Thunderbird software version 128.2.3esr (64-bit). I have 5 email address accounts 1 with google.com and 4 with outlook.com. All work perfect except 1 of the outlook.com accounts. All the outlook.com accounts are configured the same (settings, account settings etc). The error message is always "pop3.server3.2: Got an error name=pop3PasswordFailed, the server said: Logon failure: unknown user name or bad password. 2 Pop3Client.sys.mjs:1576:18".I did not change passwords. In fact, I can go on internet to outlook.com email logon web page and access the email account perfectly, even though it fails everytime with Thunderbird. (it still is same password, never changed). Plese help, I have spent some time trying to solve on my own.

Hello dear community! My firefox keeps crashing when trying to open a tab or close a tab. I can't replicate it since it happens on random tab-closing and tab-opening. I think it's just crashing when doing something like clicking anywhere and NOT when doing nothing while the system is idling. Thank you for your help! Here's a link of the crash report: https://crash-stats.mozilla.org/report/index/8ba8940e-954c-4e92-9153-0313d0241001

After auto-update to v128.2.3esr all my rss-feeds are broken. The main rss-folder Account Name has changed to "server8.invalid" and all contained rss-feeds are colored gray and are unable to fetch new messages. How can I fix this?

To optimize performance and ensure cross-browser compatibility in complex web applications, several best practices can be implemented:

   Use Responsive Design: Employ responsive web design techniques to ensure that your application functions well on various screen sizes and devices. This approach enhances user experience across different platforms.

   Minimize HTTP Requests: Reduce the number of HTTP requests by combining files (like CSS and JavaScript) and using image sprites. This can significantly improve loading times.

   Leverage Browser Caching: Implement caching strategies to store frequently accessed resources, which can speed up load times for returning users.

   Test Across Multiple Browsers: Regularly test your application on various browsers (like Chrome, Firefox, Safari, and Edge) to identify and fix compatibility issues early in the development process.

   Optimize Images and Assets: Use appropriate image formats and compression techniques to reduce file sizes without compromising quality, which can enhance loading speed.

   Utilize Best Application Development Services: Partner with experts who provide the best application development services to incorporate performance monitoring and optimization tools into your development workflow.

By following these practices, developers can create robust applications that not only perform well but also deliver a consistent experience across different browsers. Engaging with the community to share insights and experiences can further enhance our collective understanding of effective application development strategies.

Hi, I used Firefox browser at work since it had the best add-in for tab groups (Simple Tab Groups). Unfortunately browser is not supported any more. Is there a portable version that can be run without installing, from Mozilla.

I read a post that indicated it was available from PortableApps, but am not conversant enough to know that it's 100% safe. Believe that it was able to be updated as well.

I'm on a M1 Mac Mini running Sonoma 14.6.1, and my Thunderbird quit several times. I restarted and this time it isn't coming up at all. I'm going to try shutting down and then starting up after a few minutes. It started after I made a new Folder n TB and put a file into it from Experian.

I'm on an Mi Mac Mini and I was on 14.6.1 when TB updated to 128.3 esr and it crashed repeatedly. So I undated to Sequoia 15.0. That didn't help. It still crashes the minute I click into the program to open an email. I believe my only choice is to go back to an earlier version on time machine and turn off my automatic update. Any suggestions? This really sucks, guys.

Interestingly enough, I can still get my email on my iPhone running 17.6.1.

I can't access my Yahoo! Mail because the browser stay within the reCAPTCHA recognition loop.
