Tor NOTICE: Bridge 'dktoke' has both an IPv4 and an IPv6 address. Will prefer using its IPv6 address ([2a0c:4d80:42:702::1]:27015) based on the configured Bridge address.

I installed the Snowflake add-on in Firefox and when I click it it says it's enabled but how do I know that it's actually doing anything? I see this.

This update set Firefox.exe (Tor) to zero size, therefore I can't start Tor Browser. Updater.exe does nothing.

Is there any way to restore/extract Firefox.exe from update archive? Unless just reinstalling the whole bowser.

First, note this version is an alpha/development release (10.5a4, "a" for "alpha"). Most people are better off using the standard stable release.

It might be possible to extract the exe from the installer. Open the installer in an archive (zip) program. Firefox.exe is in the installer at /tor-browser_xx-XX/Browser/. Or you could reinstall the whole browser. Export/backup any customized bookmarks, settings, and bridges before reinstalling.

Don't bother digging into the update archives (mar file extension). First, they are deleted automatically after updating. Second, mar (Mozilla ARchive) is a custom file type:

This year I've started getting the "Something Went Wrong! Tor is not working in this browser." page. It started as a rare event, but is happening every day now.
It feels like the frequency is increasing with each update, but ...

Today I tried to open an .onion, after receiving the red page, and it actually worked. Checked the circuits for a few pages, and everything seems fine.

So if Tor is working properly, what is causing TorBrowser to display the red page (with increasing frequency)? Since nothing is really broken, I doubt it is related to updates, right?
