Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal “/…/” part in the path could be used to override the specified host. This could contribute to security problems in web sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

Simple to resolve Upgrade Ubuntu:23.10 thunderbird to version 1:115.5.0+build1-0ubuntu0.23.10.1 or higher…
Also looking at the code, there doesn’t seem to be any reason why gPropertiesFile can’t be:
static const char* gPropertiesFile[nsContentUtils::PropertiesFile[COUNT]
The CreateBundle method each of those strings is passed to expects a const char* with no hard-coded expectation of length. It’s static so the symbol can’t be resolved outside this cpp. Also, fwiw the new max length string in that array is 75, not 78 (including null-terminator).
Why is the setting to enable 2 rather than 1?
Apart from that it looks fine to me.
