[BUG] Downloads fail outside of logged-in container (Firefox Containers)

[offsetcyan]

Describe the bug
If the extension is run from an account logged in via a Firefox container (official Mozilla extension) Media Harvest tries to download the media from outside of the container context. If the "no container" account isn't logged in, Media Harvest will fail as Twitter's API will reject the request.

To Reproduce
Steps to reproduce the behavior:

1. Create a container and log in to twitter inside that container
2. Make sure "no container" context is not logged in to Twitter
3. Inside that container, try to activate the extension on some Twitter media

Expected behavior
Media is downloaded as expected.

Desktop (please complete the following information):

• OS: NixOS 23.05
• Browser: Firefox
• Version: 117.0 (64-bit)

The addon backend was only loaded in the default container (no container).
If you logout twitter in default container, the addon cannot get useful twitter cookie from backend.
This can be fixed but the whole workflow need to be redesigned.
Since this issue was caused by other extension, I will not do the patch in the near future.

Firefox suuport was discarded.

You can check #112 .
The firefox version would be only maintained for basic usage.
