There should be an easy way to detect the version of an installed bundle.

[yawning]

For numerous reasons, it would be nice if there was a convenient way to detect the version of an installed bundle on disk, that does not involve launching Tor Browser.

Historically there was a versions file deep within the guts of the bundle that could (and was) abused for this purpose, but with the move to rbm, the file no longer exists.

My initial inclination proposal would be that there will be a file Browser/tbb_verson.json with the relevant metadata.

 {"version":"6.5.2","architecture":"linux64","channel":"release","locale":"en-US"}

The build process can trivially auto-generate something like this, and it can be updated by the standard auto update process.

Inspired by #20792, #25012.

I made a commit in branch bug_25020 to add a tbb_version.json file:

Looks good to me, merged to master (commit 1c625c1dcbfbb1ca0b40d965c081b3f5a8f84046).

The file name is tbb_verson.json instead of tbb_version.json

Thanks for reporting this. I fixed the file name in commit e7e4cbd526d767d46fe6f728c99492e7e3d6e76c.

Micah seems interested to use this tbb_version.json file in torbrowser-launcher:

So I think we could backport it to the 7.5 series.

Done with commit 38e9d1caaa0d7cf49e4052e7c709b48ebdba9e31 and f99490f12132557981907254495d2b1d6053018e on maint-7.5. Should be available in 7.5.4.
