New Release: Tor Browser 8.5a12

by boklm | May 8, 2019

Tor Browser 8.5a12 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 fixes the issue which caused NoScript and all other Firefox extensions signed by Mozilla to be disabled.

If you used the workaround mentioned in our previous blog post, don't forget to set the xpinstall.signatures.required entry in about:config back to true after installing this update.

Note: We did not bump the Firefox version number to be able to build faster, thus it will still show 60.6.1esr as the Firefox version.

The full changelog since Tor Browser 8.5a11 is:

  • All platforms
    • Update Torbutton to 2.1.7
      • Bug 30388: Make sure the updated intermediate certificate keeps working
    • Backport fixes for bug 1549010 and bug 1549061
      • Bug 30388: Make sure the updated intermediate certificate keeps working


Please note that the comment area below has been archived.

script is still poping up with the new release, everytime you open tor and go to onion sites scripts is enabled and you hjave to manallt disable it. Not sure why but the fix is having problems.

Is the blog broken? I wrote comment 281610 (the URL to download) after clicking Reply to comment 281595 ("I want to get tor browser."). My comment should be associated with the first one and indented under it, but it isn't. My suspicions were first raised when I saw incorrectly associated replies in the post titled NoScript Temporarily Disabled in Tor Browser. Specifically, comment 281225 ("I highly doubt the completely negligible market share...") is incorrectly associated.

don't forget to

For mission-critical commands like this, say "remember to," or start directly with the command word: "Set the..."

"Warning statements should be written in the active voice, not the passive voice, and, when possible, using affirmative statements instead of negative statements. In several studies, active sentences were found to be verified faster than passive sentences, affirmative faster than negative, and true faster than false. The exception is a common warning instruction where a prohibition is required, such as “No Smoking.”

Negative and passive words in warning statements require more effort to interpret correctly. Statements having these features require a larger capacity of immediate memory than do otherwise identical statements lacking these negative and passive features."

Affirmative Warnings (Do This) May Be Better Understood Than Negative Warnings (Do Not Do That)

Wild guess: No. I looked around NoScript's site, forum, and mozilla add-on site but didn't find anything other than those words. Whatever it is, it does not change the persistence preference. It could mean it ignores the security slider.

In Android repeatedly appears that Tor is connecting (in notifications) instead of displaying the speed of browsing. I hope it's not a problem to expose the IP.

Tor still blocked In Kazakhstan.
Tor started successful but websites connection refused.
I tried different bridges it didn't help.
Work only with additional socks5. But I want clear tor :)

If Tor started successfully, the problem is not related to bridges. If some websites open but other websites returned "connection refused", the problem is between your Exit node and website. If you clicked "New Identity" or "New Circuit for this Site" but those websites still returned "connection refused", then the Exit nodes are not causing the problem. The website may be blocking tor Exit nodes.
