New Release: Tor Browser 10.5a7

Tor Browser 10.5a7 is now available from the Tor Browser Alpha download page and also from our distribution directory.
Note: This is an alpha release, an experimental version for users who want to help us test new features. For everyone else, we recommend downloading the latest stable release instead.
This release updates Firefox to 78.6.1esr for desktop and Firefox for Android to 85.0.0-beta.7. Additionally, we update Tor to 0.4.5.3-rc. This versions also fixes a crash seen by macOS users on the new M1 processor.
Note: We are investigating a build reproducibility issue for the Android packages. We identified where the packages from different builders differ and we are working on a fix for the next version.
Note: We are aware that default bridges are not currently working in recent Tor Browser Alpha versions and Tor Browser does not start, as a result. The issue is being actively investigated.
Update: The issue impacting default bridges should now be resolved in recent Tor Browser Nightly versions.
Note: Tor Browser 10.5 does not support CentOS 6.

"Bug 40287 fix" (Switch DDG search from POST to GET) is a hit on our privacy and an errosion of anonymity of all TorBrowser users, since DDG is the default search engine.
The GET method discloses the search keywords clearly in the URL request, as the URL is not encrypted by means of HTTPS. The Tor encryption is great, but a malicious Tor node can "see" the search queries in clear, and collect information on Tor users, in time leading to corellation and deanonymization. I protest.
Even the justifying reason for this "improvement fix" is quite weak (see https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/402… ):
To help that coder, simply tell him/her to open the needed links as the browser's New Tabs while keeping the original search results Tab until finished!
Is not this a natural solution we've already came to use while browsing?
