Open Doc local doesn't keep dark theme when switching page.

[Stargateur]

When doc is open on local the dark theme is not set for all local page just for the module you are on.

This is likely due to same-origin restrictions for file URLs with localStorage. You may want to check the settings of your browser, or try a different browser.

I can check the setting if you tell me what to do... My use case is for firefox, edge is worse doesn't even remember my choice if I refresh the page, chrome handle it correctly. This look more like a cargo problem than a browser config problem. I don't see why I should need to config firefox to someone else than the default.

https://bugzilla.mozilla.org/show_bug.cgi?id=507361 suggest a bug that have been fixed without any configuration needed.

I think with firefox you have to set security.fileuri.strict_origin_policy to false for it to work. Note that I don't necessarily recommend doing that, since it is on by default for a reason, so evaluate your security needs as necessary.

I think the only solution is for Cargo to have a webserver, and to stop using file: URLs. This is tracked in #4966.

You can also run your own server. If you have python installed, it is pretty easy to do with python -m http.server in the target/doc directory.

already set to true, it's the default, unless I missing something this option is not related to localstorage.

Nevermind false work but why true doesn't work ?

Local documents have access to other local documents in the same directory and in subdirectories, but not directory listings. (Default)

I don't really know, it's possible the docs haven't been updated. Same-origin for "file" changed a little over a year ago (https://www.mozilla.org/en-US/security/advisories/mfsa2019-21/#CVE-2019-11730), and they've been tweaking it since then (like adding font support).

Regardless, I don't think things are going to universally work without a local web server.

Closing in favor of #4966.
