Was anybody else just burned by the Tor Browser flatpak?

cross-posted from: futurology.today/post/4000823

And by burned, I mean "realize they have been burning for over a year". I'm referring to a bug in the Tor Browser flatpak that prevented the launcher from updating the actual browser, despite the launcher itself updating every week or so. The fix requires manual intervention, and this was never communicated to users. The browser itself also doesn't alert the user that it is outdated. The only reason I found out today was because the NoScript extension broke due to the browser being so old.

To make matters worse, the outdated version of the browser that I had, differs from the outdated version reported in the Github thread. In other words, if you were hoping that at least everybody affected by the bug would be stuck at the same version (and thus have the same fingerprint), that doesn't seem to be the case.

This is an extreme fingerprinting vulnerability. In fact I checked my fingerprint on multiple websites, and I had a unique fingerprint even with javascript disabled. So in other words, despite following the best privacy and security advice of:

1. using Tor Browser
2. disabling javascript
3. keeping software updated

My online habits have been tracked for over a year. Even if Duckduckgo or Startpage doesn't fingerprint users, Reddit sure does (to detect ban evasions, etc), and we all know 90% of searches lead to Reddit, and that Reddit sells data to Google. So I have been browsing the web for over a year with a false sense of security, all the while most of my browsing was linked to a single identity, and that much data is more than enough to link it to my real identity.

How was I supposed to catch this? Manually check the About page of my browser to make sure the number keeps incrementing? Browse the Github issue tracker before bed? Is all this privacy and security advice actually good, or does it just give people a false sense of security, when in reality the software isn't maintained enough for those recommendations to make a difference? Sorry for the rant, it's just all so tiring.

Edit: I want to clarify that this is not an attack on the lone dev maintaining the Tor Browser flatpak. They mention in the issue that they were fairly busy last year. I just wanted to know how other people handled this issue.

It was collapsed for me at first, and buried under a lot of other comments, but a workaround is mentioned here. Unfortunately, that didn't seem to work for me, but deleting the Flatpak and deleting all associated data, and then reinstalling it, I think did the trick.

Although it does now show this warning, which doesn't sound great.

Edit: actually, I think that was the reason I concluded the first workaround didn't work, but looking at that URL, this might just have been introduced in Firefox 128, which is newer than the old version of Tor was based on. So it looks like both worked.

Not possible to upgrade (older) TB using internal updater · Issue #5 · flathub/org.torproject.torbrowser-launcher

How can TB upgrade itself while it has no ability to do that from within the browser? (even notification of new version its not shown, i need to do that all manually)
