So what are the plans for content at:

V2 addresses are being deprecated too early.

The work that has been done to date to make v3s more accessible is inadequate. Please resume support for v2 (possibly with warnings) until an better solution is found, having to use old code bases is suboptimal.

Unfortunately that isn't realistic. Version 2 onion services have lived longer than they should. They will likely not be secure within the next five years, and we won't know when that happens until it's too late. Simply adding a warning will not force migration to version 3 addresses.

Accessibility of v3 addresses will improve as more people use them and the community adopts a solution.

People in the community are saying there is a problem with the current tools and then Tor Project tells them, "Community you try to work out how to deal with problems we create." That's really not right. We do have time to work out a solution, so work it out first regardless of what we think about how long we've been using them. Also, I've seen suggestions provided, over the years and they seem to get ignored. It is overkill to have 50 chars. Expect hidden services to jump ship to I2P and renewed interest in other anonymous networks, because I'm going to be honest here, this is not good at all. I already see services breaking down and now I'm under the impression Tor devs don't want to use a solution.

1. This is a known issue. The Tor Project is part of the larger Tor community, and a solution will be found one way or another. However, the security, anonymity, and privacy properties of Tor must be maintained and moving to v3 addresses is necessary.

2. Version 2 onion services had similar usability and accessibility issues, those issues were simply less extreme. Some sites created vanity addresses, but that is not a solution for everyone and vanity addresses lead to other problems. In short, v3 onion addresses are not significantly worse than v2 addresses.

3. 50 characters is not overkill. This is the correct length for Tor's security parameters.

4. If you or anyone else has a viable solution, then please restart that conversation. We are already testing Namecoin and a centralized list.

> having to use old code bases is suboptimal.

There's the crux of it based on the comments I've read--libraries, modules, and userspace applications that aren't updated to version 3 onion services. Could you all MAKE A LIST of those and write them in a bug ticket, reddit thread, on a wiki, somewhere so at least they're together and everyone can find quickly which software projects are in need of repair?

Add Burmese as a new locale

For Myanmar. Become a Tor translator. It's safer for people living outside of Myanmar to become translators of Burmese (language code: my). To sign up, you need an e-mail address. If you want more pseudonymity, you can create an e-mail inbox that is on a temporary service or an address that you intend to use only for Tor Project. Some e-mail services allow you to create and login to the e-mail address through Tor. If you do that, then also adjust your behavior (OpSec) based on your threat model.

An old Tor bug biting me sometimes:

[warn] {DIR} Received http status code 404 ("Consensus is too old") from server x.x.x.x:443 while fetching consensus directory.

Whenever Tor has started with this error message, all my v3 onionsites are unreachable, and I have to restart Tor. V2 onions are not affected. Please fix ASAP.

Yes, tor needs a recent consensus so it can reach v3 onion services. This is a requirement.

Would it be possible to retry downloading the consensus from different entry nodes until it gets one that is recent enough?

Did you change any settings in Tor, or are you using the default configuration in Tor Browser? Did you enable bridges?

No Tor settings changed, no bridges enabled.

Did you change any settings in Tor, or are you using the default configuration in Tor Browser? Did you enable bridges?

No Tor configuration changes besides setting up the onion services, and no bridges enabled. Apparently the client always tries to fetch the consensus from the same directory guard even if it failed, and the retry interval is 90 minutes, which is too long.

When I opened Tor browser before the 10.0.16 update there was one tab open and on the right of the tab was a '+'. When I clicked this '+' a new tab opened, which was extremely handy. Since the 10.0.16 update this '+' has disappeared and now I can only open a new tab via File in the menu bar and then selecting 'new tab'. I find this very annoying so I uninstalled the update and reinstalled the previous version.

> this '+' has disappeared and now I can only open a new tab via File in the menu bar and then selecting 'new tab'.

Were you customizing the toolbars? It sounds like you accidentally dragged the New Tab button off of the toolbar. Open the main menu in the top right (also known as the hamburger menu because the button's icon is 3 horizontal lines). In the menu, click Customize... The window will change and have a grid of button icons. Find the icon named "New Tab," and drag it with the mouse into the toolbar near the spot you want the button to be. Finally, at the bottom right, click Done.

Since you're using the File menu, you can also find the Customize item in the View menu --> Toolbars --> Customize...

> which was extremely handy.

Tor Browser is based on Mozilla Firefox. Standard browser features such as tabs are adopted from them. They are free/libre open source software.

I used tor browser on Windows 10 with safer setting, to download from rapidgator. Rapidgator don't allow me to download again in the next 2 hours. So I used the new identity feature in the browser and tried download another file from rapidgator but rapd gator said no download for next 2 hours for this ip address. I tried the safest setting and did the new identity 3 four times, yet rapidgator identified my ip address and said no downloads for next 2 hours. So rapidgator can easily identify a tor user, it's not anonymous at all

This is not an uncommon thing that happens when you use tor. All the millions of tor users are using the same ~1000 exit nodes. If RapidGator limits your usage, you're bound to have been affected by someone else's usage.
