Thunderbird unable to connect to servers
HI all,
I have been not able to access any of my accounts on Thunderbird for more than two weeks because Thunderbird seems not able to connect to the servers. Without no apparent reason, one day Thunderbird did no longer make me access my email accounts (I have two accounts on it), and I could not receive or send any email. I tried the steps suggested in https://support.mozilla.org/en-US/kb/cannot-receive-messages , but my account information is correct. I can also access one of my accounts on the web-mail interface provided by the ISP.
While showing this problem, Thunderbird hang at "Checking mail server capabilities". So I tried to remove and reinstall the accounts, as this was suggested in https://support.mozilla.org/en-US/questions/1184205 , but it didn't work. Then I tried uninstalling and reinstalling Thunderbird, but it did not solve the problem. During reinstallation, Thunderbird downloads and opens normally but, when I try to set up one of the accounts, Thunderbird hangs at "Mail for [emailaccount@imap]: Sending secure login information...".
Finally, I had seen in this post https://support.mozilla.org/en-US/questions/1153602 that it could be a firewall problem, but I don't find any sign on my firewall that indicates that it is blocking Thunderbird. I am using Ubuntu 17.10, with GUFW as Firewall manager. I have upgraded to Ubuntu 17.10 not a long time ago, but the problems did not seem to be linked to the upgrade. I have just reinstalled Thunderbird from the website so its version should be up to date.
I don't know what else to try, so I would really appreciate some help to solve my problem! Thanks in advance

This sounds like the Firewall.
re :I don't find any sign on my firewall that indicates that it is blocking Thunderbird. Usually, it does not necessarilly say it is blocked, but if not in list and set as allowed then it is assumed as blocked. Thunderbird must be in the list and set as allowed. Maybe you have to allow the 'ports' Thunderbird uses.
Hi Toad,
thank you for your reply. I am not very familiar with changing firewall settings, but I have set some exceptions to my firewall, and it should now allow in data from ports 143 and 993 (IMAP and IMAPS). Both the accounts I use on Thurderbird use IMAP port 993. I changed the settings following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-with-ufw-on-ubuntu-14-04
However, the situation in Thunderbird does not seem to be improving. I rebooted after changing the firewall port settings, but Thunderbird hangs exactly like before. Also, after reinstallation I have not been able to set the launcher, and I am forced to start Thunderbird from terminal. When I do so, I also get the following warning: "[calBackendLoader] Using Thunderbird's builtin libical backend 1526995970690 addons.webextension.s3google@translator WARN Loading extension 's3google@translator': Reading manifest: Error processing permissions.1: Unknown permission "unlimitedStorage""
I see this relates to an add-on I have (a translator), but I am not sure if it has anythign to do with my current problem. Am I doing something wrong?

The most common fire wall to cause these sorts of issues are those software that come as a part of the various "internet security suites". Nortons has one that is notorious. but it is not alone.

re: an addon extension. Maybe it is not an up to date version in order to work with current Thunderbird. You could try updating.
https://addons.mozilla.org/en-GB/thunderbird/addon/s3google-translator/versions/?page=1#version-6.15 There is a Version 6.15 Released April 4, 2018
Hi all,
thank you for the replies. I tried updating the add-on, but unfortunately the latest version is not compatible with Thunderbird yet, which might be the reason for the warning - so this is a separate issue.
I tried disabling the Firewall completely, but Thunderbird is still unable to connect and gets stuck loading. If the problem still appears with the firewall disabled, is the problem somewhere else? Is there anything I can do or check to verify where the problem is?
I provide in attachment the Troubleshooting information from Thunderbird in case it can be of help:
Thanks again for your time.
I notice there are a few crash reports which have not been submitted. Here is some info on how to submit them and how to open and read them. https://support.mozilla.org/en-US/kb/mozilla-crash-reporter-tb
You could try removing the global database file. https://support.mozilla.org/en-US/kb/rebuilding-global-database
The add-on you have posted the errors for is using web extensions. Thunderbird has no support for web extensions in add-ons.
Looking at the the add-ons page I see the developer links to version 5.35 for Thunderbird. As later versions use web extensions, they will simply not work with Thunderbird.
Hopefully we can put these sorts of discussions behind us once the migration to addons.Thunderbird.net occurs. Then the add-on site will only have the Thunderbird versions listed.
Hi Toad, hi Matt,
thank you for your replies. The add-on is not really a problem (also, Thunderbird seem to be still using the 5.35 extension despite the upgrade to 6.15 that causes the error message). Also, please note that all my crashes reports are correctly submitted.
I tried rebuilding the global database, but it did not seem to have any effect. The global-messages-db.sqlite variable was rebuilt in the /.thunderbird folder, but Thunderbird still keeps hanging at startup and is not being able to connect. I tried again disabling the firewall and changing firewall settings, but nothing changes the situation: even with the firewall disabled, Thunderbird still does not work.
Would you have any other suggestion? I really don't know what the source of the issue is, nor how to fix the problem. Thank you very much again for your help, L
