TB 91 not sending mail while bordercolors-d is active

[peter-rindfuss]

Hi, With the new TB 91, I cannot send messages anymore while bordercolors-d is active. Simply nothings happens, and the compose window stays open. Disabling bordercolors-d solves the problem. My precise TB version is 91.0.3. I like the add-on, and I hope there will be a solution. Peter

Hello Peter, thank you for bringing this to my attention.

I have been testing the add-on on Beta version, but I have not tried the actual TB91 release. I'll get it installed in the next days, and see if I can reproduce the issue.

In the meanwhile, could you double check that the cause of the issue is really BorderColors, and see if there is anything in the logs?

• Disable all add-ons except BorderColors
• Restart Thunderbird
• Open the error console from Tools \ Developer Tools \ Error Console
• Clear the log with the Bin icon in the top left—we'd like a clean slate
• Open a new compose window, try to send a test email
• If any red text appears in the logs, of any of the messages look suspicious to you, post the contents here—please amend any personal information first

Thank you!

Hello again Peter, I have tried to reproduce the issue on the latest Thunderbird version without luck: I can compose and send emails without trouble.

Still, we could dig a bit further and see if we can solve the problem for you. Do you think you could help me with the steps in the message above?

Hi, I already replied by mail, but it looks that it did not reach you. So here it comes:

The problem occurs, reproducibly, with BorderColors being the only add-on.

This is the error log:

11:06:35.580 window.controllers/Controllers sollte nicht mehr verwendet werden. Verwenden Sie es nicht für die Browser-Erkennung. blank
11:06:35.928 Uncaught Exception { name: "NS_ERROR_FAILURE", message: "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIEditor.getInlineSpellChecker]", result: 2147500037, filename: "chrome://messenger/content/messengercompose/MsgComposeCommands.js", lineNumber: 401, columnNumber: 0, data: null, stack: "updateEditableFields@chrome://messenger/content/messengercompose/MsgComposeCommands.js:401:38\nComposeFieldsReady@chrome://messenger/content/messengercompose/MsgComposeCommands.js:2739:23\nNotifyComposeFieldsReady@chrome://messenger/content/messengercompose/MsgComposeCommands.js:461:5\nInitEditor@chrome://messenger/content/messengercompose/MsgComposeCommands.js:9242:15\nobserve@chrome://messenger/content/messengercompose/MsgComposeCommands.js:3803:9\n", location: XPCWrappedNative_NoHelper }

The "Uncaught Exception" occurs after opening the composer window. The "NS_ERROR_FAILURE" shows up after the sending attempt. When Border Colors is disabled, the "Uncaught Exception" shows up twice, the second occurance replacing the NS_ERROR_FAILURE.

As this seems to be related to an "InlineSpellChecker", the fact that I use the German version of TB may be relevant.

Sorry, the comment by email never appeared 🤷‍♂️

On the other end, I managed to reproduce the issue installing a "Fully localised" version of Thunderbird, in my case I tried with "English (British)" which makes debugging a bit easier for me 😉

I'll have a look in the next days, thank for your help and patience!

[peter-rindfuss]

I installed the "German Dictionary", and now I can send.

[dreadnaut]

Indeed, I have tried the same here and after installing a dictionary the error is gone.

Odd behaviour. I'll see if there's anything I can do to avoid the issue, but I might file a Thunderbird bug as well.
