tor-browser cannot install extension via browser

[unode]

Issue description

The latest tor-browser-bundle-bin implements and extensible mechanism that allows adding extensions via nix.
The current implementation replaces the extensions folder in the user's profile directory with a symlink to a /nix/store path.
The extensible mechanism comes at a cost of disallowing installation of extensions through the browser, the most common use-case.

Is there any possibility for a middle ground?
I'd like to still be able to install addons through the browser.

Steps to reproduce

Launch tor-browser
Open add-ons menu
Search and try to install any extension

Note that only the from-source bundle supports declarative extensions. It also supports installing additional extensions from within the browser.

I think allowing that for the prebuilt bundle should be easy enough, I'll look into it.

Just to clarify, I was referring to

nixpkgs/pkgs/applications/networking/browsers/tor-browser-bundle-bin/default.nix

Line 305 in 7bf1913

ln -snf "$TBB_IN_STORE/TorBrowser/Data/Browser/profile.default/extensions" \

which seems to be absent from the source based build.

[joachifm]

The from-source version relies on a different mechanism for preloading extensions. I expect that using the same mechanism in the binary version would remove the need for the symlink.

Works for me now

Works for me too but I had to rm .local/share/tor-browser/TorBrowser/Data/Browser/profile.default/extensions first.

Thanks

Ah, yeah I forgot about that ... I'll make a note to maybe add some logic to remove the symlink if it exists.
