Additional information

I set launchctl setenv OLLAMA_ORIGINS "*".

The models from Ollama are retrieved in the plugin settings, which suggests that OLLAMA_ORIGINS is set; with this, Ollama also works in the Brave browser in parallel.

The error occurs when I try to use ThunderAI as well as when summarizing prompts.

This is not an error from ThunderAI, there is no background-bundle.js file. Are you using another AI addon?
The other error is from ThunderAI and the error is the same. It seems that your AI server is refusing connections from both addons.

Hello,

thanks for the reply.

The error only went away after I disabled ThunderAI Sparks. Now Thunderbird itself says AI Sparks is not compatible.

[evolts21]

It's really strange, Sparks is not connecting directly with the AI server.
Have you updated to 149? I see that Sparks compatibility has not been yet updated.

I restarted Thunderbird earlier and the error came back:

Thunderbird Version 149.0 - Update was automatic

The following add-ons are active:

Auto Adress Cleaner
cloud - Filelink for Nextcloud
Expressions Search - NG
LanguageTool
ObsidianClipper
Paperless-ngx Uploader
PrintingTools NG
uBlock Origin

The only addon that could interfer with a connection to a server is uBlock Origin.
You could try to disable it and test.

On the Ollama server logs there is something useful to understand why the server is sending a 403 Forbidden?

I updated Sparks compatibility on the Thunderbird site, it could need sometime to update on the client.

[syrabo]

Hello,

I disabled uBlock; now it works. Now I need to decide which plugin is more important.

Thank you!

[micz]

You can check the uBlock documentation, there should be a way to whitelist your Ollama server so you can use both addons.
