New Release: Tor Browser 8.5a11

Tor Browser 8.5a11 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 new alpha release includes some bug fixes and improvements. Among other things, on the desktop side we improved the browser toolbar layout, replaced the security slider with a toolbar icon and added mechanisms to introduce new features to users. We also improved the screen reader accessibility on Windows and added the es-AR locale.

On the Android side, we started using the Tor Onion Proxy Library.

After opening the TorBrowser, I get the following message: "NoScript could not be verified for use in the Torbrowser and has been disabled."

I`m using macOS Mojave 10.14.4

Should replace OS X to macOS

Why was the NoScript extension disabled in my Tor Browser? It says that NoScript is obsolete and no longer supported by Tor Browser.

I just installed TBB 8.5a11 x64 bit to test a disabled Noscript problem that I discovered today in the stable TBB 8.0.8. The newer version of Noscript is also disabled in TBB 8.5a11. The hamburger>Add-ons>Legacy comment is the same as for TBB 8.0.8 x64bit: "Noscript could not be verified for use in Tor Browser and has been disabled". Scripts are being allowed in the safest security level. Twitter has previously failed to load in "safest", but has loaded in "safer". Now ... boom! It loads with security level set at safest. I wonder if this is a Mozilla problem. I'm using Windows 7 Pro x64bit. Thank you.

does this version have same recent extension's install problem ??

Tor 8.0.8 is not updating
to 8.5 of 16th April ?!

Is 8.0.8 then corrupted ?

There is no 8.5 released yet, so everything is fine. However, you should get an update to 8.0.9.

When is Tor going to put out a fix that is going to stop the ddos attack from happening.
Currently there are many sites on the tor nework that are under heavy ddos attacks.

We need a solution, we need a patch....


The problem is not easy to fix. We are working on it. See for instance

Still no way to save or download images so its still completely useless to me tbh!
