No Option for Implementation of Addons & Extensions for Mobile Browsers

  • There is no option to install addons & extensions with most mobile browsers of the Google Chrome family ( Google Chrome, Opera, Microsoft Edge ) :-(. I.e. you may not implement such extensions for these mobile browsers :-(.
  • 2023-11:
    • Yandex Mobile just offers 3 addons :-(, so no simple option to get a self-developed addon on this list :-(.
    • Firefox Mobile just offers 21 “recommended” extensions, so no simple option to get a self-developed addon on this list :-(.

Microsoft Exchange & Microsoft Outlook - Resources

  • eGovernment Computing.
    • Newspaper 06/2022, page 11, article “Open Source. Linux im Public Sector” - “Als zweite Herausforderung wird eine alternative Groupware genannt. 'Microsoft Outlook' hat sich längst zum Standard entwickelt. In der Studie wird empfohlen, die Umstellung der eMail und Groupware-Applikation im Rahmen einer Umstellun des eMail-Dienstes auf ein Open-Source-Produkt durchzuführen. Aber: 'Problematisch bezüglich der Nutzung von MS Exchange als eMail-Dienst in Kombination mit einer anderen Open-Source-Mail-und-Groupware-Applikation ist das lizenzrechtliche Verbot innerhalb der USA, das von Microsoft patentierte ActiveSync-Protokoll in Open-Source-Anwendungen zu implementieren'. Aus diesem Grund gebe es keine Open-Source-eMal/Groupware-Client-Applikationen, die man gegen einen MS-Exchange-Dienst verwenden könne. Problematisch sei diesbezüglich auch, dass für eine Outlook-Ablösung nicht nur das Mailprogramm ersetzt, sondern auch das vollständige Mail- und Kollaborationsbackend MS Exchange durch eine andere Software abgelöst werden müsse”.

Error Messages, Tips & Tricks

Installation Process for given E-Mail accounts with existing Thunderbird Mail Directory
  • Howto:
    1. Call Thunderbird.
    2. Step 1:
      1. “Configuration / Option” - Select ”[x] Menu Bar”.
      2. “File / New / Existing Mail Address”.
      3. Fill in the data of your mandatory E-Mail account, then press the button “Continue”.
      4. Select ”[x] POP3”.
      5. Press button “Manual config”.
      6. Press button “Advanced config”.
      7. “Account Settings”.
        1. ”[x] Attach the signature from a file instead (text, HTML, or image):” and select a file by the browse button.
      8. “Server Settings”.
        1. Unselect ”[ ] Check for new messages at startup”.
        2. Unselect ”[ ] Check for new messages every XX minutes”.
        3. It is very urgent to unselect ”[ ] Automatically download new messages”.
        4. Unselect ”[ ] Leave messages on server”.
      9. “Composition & Adressing”.
        1. Unselect ”[ ] Compose messages in HTML format”.
      10. Press button “Ok”.
    3. Step 2:
      1. Open the just created profile by mouse-rightclick.
      2. “Server Settings”.
      3. “Local directory”: Press button “Browse” and select the existing mail directory for the account.
      4. Press button “Ok”.
      5. Thunderbird asks you “Thunderbird needs to restart to apply the change of the Local directory settting”. Press button “Restart”.
  • The motivation:
    • During a recent installation of Thunderbird 31,
      • I selected by error a IMAP account for testing my E-Mail provider account :-(,
      • without deactivation of the message download option :-(,
      • and then ( see step 2 ) I selected the existing POP3 mail directory for the account as new local directory.
    • The effect was that my “Sent” directory and a few other directories were emptied :-(, if I remember right the “failure of filtering” bug appeared during the download. But Thunderbird definitively wiped out the contents of some email subdirectories by own activity :-(.
"AppHangB1" with Thunderbird
  • After new installation of Windows and installation of Thunderbird 31, including the creation of a new Thunderbird user profile, Thunderbird did not work properly, but Windows told me that Thunderbird is in Google "AppHangB1" mode. The application was not usable, after 1 or 2 mouseclicks it “hanged” and just showed the Windows sandmill.
    • It did not help to deinstall and reinstall neither Thunderbird 31 nor 24.01 - The “hanging” happended every time.
    • Thunderbird 17 installed properly, but was not able to use the Thunderbird 31 & 24.01 profile properly - so it did not display the mail folders, though it knew about the account.
    • The only help was to delete the Thunderbird profile - the “hanging” did not appear again neither with Thunderbird 31 or 24.01.
How to delete a Thunderbird Profile
Thunderbird: Sending E-Mails by SMTP fails
  • Error message while sending an E-Mail by SMTP, by E-Mail provider GMX:
    An error occured while sending mail. 
The mail server responded: 5.7.0 Authentification expired (mp016). 
Please check the message and try again.
  • Solution: Login at the Web portal of GMX. GMX suspended your account ( due to a login attack attempt ) and asks you to setup a new password, by the Web portal. After that, with new password, E-Mail sending works again.
Thunderbird: Restoring messages from .mozmsgs Folder
  • Keeping the default option “Allow [your OS's search engine] to search messages” creates a backup of Thunderbirg messages, in extra subdirectories, but in the same file system path. You may later import these messages into Thunderbird, if necessary.
  • Getsatisfaction - Thunderbird "*.sbd and *.mozmsgs files reappearing on HD" - “The .mozmsgs directories store data that allows Windows Search or Spotlight to index your mail folders. They are filled up if you let your computer remain idle for some time and keep Thunderbird open. You can easily turn it off from Tools-Options or Preferences, in the Advanced pane, General tab. You'll find a checkbox saying 'Allow [your OS's search engine] to search messages'”.
  • Mozillazine "recover lost emails from Inbox.mozmsgs folder", 2009-05-04.
    • “I copied the missing files from the *.mozmsgs folder in my profile to a new folder. Used the command prompt to change the file extension from .wdseml to .eml and then used Import/Export Tools Add-On to import the missing messages back into Thunderbird” :-).
    • “It should be noted that the wdseml files do not contain any attachments that may have been part of the original message” :-(.
Thunderbird 24.1.0 .. 24.5.0..?: Failure of Filtering
  • Error message when receiving E-Mails and sorting it into folders according to filter rules:
    The messages could not be filtered to folder '%S' because writing to folder failed. 
Verify that you have enough disk space, and that you have write privileges to the file system, 
then try again
  • Bugzilla@Mozilla "Bug 931303 - message could not be filtered to folder because writing to folder failed".
  • Thunderbird 24.0.1 is currently the latest stable release, as of 2014-05, without this bug.
  • Tip: If you switch back from Thunderbird 24.5 to 24.0.1, please compress all folder data by Thunderbird itself, to get rid of the bug.

Selection Criteria for Computers with Intel iCore 5 / iCore7, internal Graphics Card, Intel vPro/AMT Technology

Motherboard
  • Must be shipped with vPro technology.
  • Must provide suitable AMT technology ( AMT 6 or newer ). Be aware of motherboards which provide vPro technology but insufficient AMT technology ( e.g. AMT 5 ).
CPU
  • The motherboard / computer must be shipped with a vPro enabled CPU :-). With many computers, the manufacturers provide optinal CPUs both with and without vPro, without explicte naming of the vPro feature.
  • The bundeling of a vPro CPU with a motherboard is no indictor that the motherboard supports vPro technology. Especially, the support of vPro technology is no indicator that there is sufficent AMT technology.
Your Questions to Motherboard Manufacuters and its Vendors
  • “Does your motherboard support Intel vPro Technology with AMT 6 or newer, with activated CPU-internal HD2000 / HD3000 Intel graphics card ?”.
  • “Definitely, may I address the switched-off computer by Ethernet network, and log on the internal AMT server and the VNC server?”.
Warning
  • There is the mission of Intel, to deliver the vPro technology just to the “system houses” and to the “business” sales channel ( → computers shipped with Windows Professional ), not to “consumer electronics supermarkets and consumer electronics store chains” and the “private users” channel ( → computers shipped with Windows Home Premium ).

If you don´t do so, the rumour says that then you will get a computer without working remote access. Maybe it is not possible to order this option by the online order process ?!
