Thunderbird 128 doesn't allow URLs for Icons

Starting with Thunderbird 128 it is no longer possible to specify any random URL for the icons of the Space entries. As far as I understand, only so-called "strictRelativeUrl"s are allowed. I tried passing an object URL to a blob instead but that is also refused. Since it also doesn't seem that an extension can store or access files locally (tbh I rather glad about that in general. Though, an isolated folder on the file system wouldn't hurt) I cannot download and store icons at runtime and create the Spaces entries using these.

The current result is, that the application crashes at startup and does not create any spaces at all. I could disable the custom icons but this means (at least at the moment) that the extension icon is used for all entries which makes them a bit hard to distinguish (read: no possible at all).

As far as I can see there is no option at all for fixing this and showing the web app icons in the Spaces toolbar.

I have one possible workaround in mind: create numerous icons with just to letters (e.g. Yo or Lo) and use them automatically based on the first to letters of the web app name. While this could lead to collisions it would at least be some possibility to continue this extension.

But to be frank: Given this setback as well as the other currently ongoing problem that the listeners for changing the User-Agent on the web app pages is only working for about 30 seconds after Thunderbird is started because then the background script is killed really strain my motivation to continue working on this... We'll see.

This issue is crossposted to my Forgejo instance as well as GitLab and GitHub.

I decided to implement a workaround which either wasn't possible back in August or that I didn't notice. It is possible to add the icons using a coloured badge. The icon is the one of the add-on, but in the top right corner there is a badge with a custom text (I chose to use the first two letters of the web app name) and customisable background colour. This is by far not an ideal solution since the text is quite small and its hard to differentiate the different entries. But as far as I can see, there is still no other way.

Therefore, I don't consider this issue resolved and I won't close it.
