hello,
is there a plan on when tor will upgrade to firefox 91 esr?

also, i want to highlight the importance of arm/apple silicon support in that macos build then (for macbook air 2020 and other current devices). firefox 91 esr has native support for that and its important because having to rely on the optional backward compability layer for intel64 apps in macos is not a good thing.
if my understanding of apples information is correct (see "Building a Universal macOS Binary" article), then it is possible to ship one binary which includes both versions, so to speak.

thank you for your outstanding work for the internet.

Is this a problem for Tor and the TBB?

Timeless Timing Attacks
In this presentation, we introduce a conceptually novel way of performing timing attacks that is completely resilient to network jitter. This means that remote timing attacks can now be executed with a performance and accuracy that is similar as if the attack was performed on the local system. With this technique, which leverages coalescing of network packets and request multiplexing, it is possible to detect timing differences as small as 100ns over any Internet connection. We will elaborate on how this technique can be launched against HTTP/2 webservers, Tor onion services, and EAP-pwd, a popular Wi-Fi authentication method.

Hello,
I believe it is due to this update that now I cannot log in to Odysee and cannot see the number of views and followers of channels on Odysee. It was about a week ago (so roughly around the 10th Aug) when this problem begun. It is not an Odysee problem, as it is not present if I use a different browser.
Can you please advise/fix it?
Thanks!

Snowflake stopped working in two sessions so far, so I had to restart the browser. Could not connect to any websites. I was using public WiFi that maybe had a firewall. Both times, the browser was idle for many minutes before I found it could not connect. Obfs4 does not do this. Linux 64.
