TOR 9.5 (based on Mozilla Firefox 68.9.0esr) (64-bit)

Suddenly my browser has a grey bars on the bottom and sides when it opens. Site doesn't matter. Resizing the window changes the size of the bar. The bars cycle through small to big and repeat it as you change window from smallest to biggest.

I am not able to view any webm videos saying "No video with supported format and MIME type found" and every download saying unknown time left

I've run into this problem too. Specifically, on http://invidio.us, sometimes the video stops mid-stream, and it shows the MIME type error. When downloading (save video as...), the download will sometimes fail part way through, and the resulting media file shows the correct duration, but the video freezes at the point the download failed. This is on 9.5 and 9.0.10.

I think the server (or Firefox) attempts to automatically downgrade to a lower-quality format when it detects too much buffering. This sometimes results in the MIME type error. Maybe it could be downgrading from MP4 to webm, or from one codec to another, and not just a lower resolution? Could there be something wrong with the Accept: header? I've noticed with JS disabled, it sometimes causes the video to start over at the beginning in lower quality, presumably because there is no JS to seek to the right time in the video. Presumably this means the particular video is available in a lower-res format that happened to be supported, which might not always be the case? It doesn't seem to happen when you select the format and use the download button on invidious (instances where it's enabled), but I haven't tested it enough. I've also noticed it is much more likely to happen when you have the "proxy video" preference enabled on invidious, which is slower, and is enabled by default on some instances. You can probably reproduce it by watching some HD videos on invidious or other sites over a slow circuit.

I'm really not sure what we should do with this. VirusTotal doesn't say *why* System.dll is detected as malicious.

Thank you for the new version!
Is there a way to change the GUARD node from the browser in this new version?
Last few days Tor is so slow. So slow, it makes using Tor impractical.
When I press "New Circuit for this site" button, nodes change with the exception of 62.210.148.97 (a Guard site in France). I suspect this node is the bottleneck. After pressing about 60 times, I was lucky to have another Guard node (in Germany) and I was able to have decent browsing. That lasted for a few minutes and I was back to the same French note.
How can I change guard node? How can I avoid a specific guard node? If there is no such facility please kindly consider providing it.
Thank you.

Unfortunately the browser does not have a good interface for this. If you quit Tor Browser and delete the file named 'state' within the "Client's Configuration" directory as described on the following page, then you should get a new Guard node when you restart the browser. Please be aware, that Guard nodes are used for protecting you, so only change it when necessary.

I used tor years ago and there was a software offered for windows users to become a relay. Why was this offering ended>? It seemed more simple to download the software and turn it on to make the relay go live. I have 50 to 100mb/second bandwith and will be on gigabit bandwidth soon. It would be easier to have that software again. can I use the old version from your downloads page?

no one ever mentioned: how d'u go from latest tor version 9 to tor 10 in only less than 24 hours?

Tor Browser versions increase by 0.5 between the "stable" series and the "alpha" series. In this case, the "stable" series moved from 9.0 to 9.5, and the alpha series moved from 9.5 to 10.0. Historically, Tor Browser versions ending with ".0" do not have many new Tor-specific features but they are based on a new Firefox ESR version (52esr, 60esr, 68esr). Tor Browser versions ending with ".5" usually include a few new Tor-specific features (or privacy protections). This pattern is mostly due to available developer time.
