I like this but it didn't work correctly as intended. I received this warning when I clicked on record "Security error: open the video in its own tab. Open in new tab" I did as recommended and it downloaded the recording to a file. it was a big file 1.1GB as the recording was 3h but the recording worked so I'm happy about that.
I tried it again though and this time it didn't work. I stopped trying after that but will give it another try on some other recordings to see how it work on those.
thanks for developing it it has worked better than most others I have tried.

This is just little bit better than useless. Can be used if using only one tab and for shorter recordings. With more tabs it crashes whole Firefox or can not be restarted. Its high school project level,failed one. Not recommended.

I like this addon - the latest version crashes all the time (immediately when I clicked the extension icon) so I downgraded to version 1.6 and all is well again. :)

I am using 67.0.4 (64-bit) firefox. Maybe I should consider upgrading it (?)

If I could only make one suggestion, I would love to be able to improve the video quality of the recorded webm file. I really don't care how big the resulting file is.

Even if I could 'hack' it myself, it would be great... I don't worry about the size since I use ffmpeg to re-encode it smaller after.

Other than that, I think this is a fantastic add-on.

Edit - I updated firefox and then this addon to 2.0 - it is even Better than before. Super job, I love this extension. please advise on if I can contribute for it.

Thanks, reply much appreciated. This is a different id because of the way Firefox works. I put the default 4* on this one ;) In answer to your questions as best I can:

* Firefox 68.8.0esr (up to date)
* Thanks for the downgrade info, I also found it in an obscure part of the Firefox info and can confirm LiveRecorder v1.6 still works fine on the same video where v2.0 fails.
* The simpler interface showing under the media after clicking the extension icon in the toolbar now only has two buttons, don't know if something is missing.
* You click record and it now counts up the Mb (a new feature).
* You click stop and get the error immediately which, tbh, looks like a code error referring to something undefined.
* It happens consistently, every single time, on all the several streams I have tried and every attempt. It also happens whether or not you have paused recording. For me at least, it looks to be a 100% failure where it isn't possible for it to work at all any more.
* The only thought I had was if Firefox changed something you now rely on between v68 and the latest (non-esr) version. LiveRecorder v2.0 might need a higher version than Firefox 68.
* Until I get to that on the Firefox esr channel, v1.6 works just fine, so thank you for a great extension. :)

While writing, just to point out in your documentation the FFMpeg command line you give to re-write the WebM file doesn't work (don't know if it did before). It doesn't re-write the timestamps with that simple command or even if you add options to ignore input timestamps and re-generate output timestamps. The lack of timestamps in the frames bacause of the Firefox bug confuses it and, on conversion, it writes a video with all 10,000 or whatever frames playing at 10,000 fps in 0s. Ooops! I have tried all the suggestions found by online search without success. However, HandBrake understands the WebM just fine, so you need to use that not FFMpeg (although I normally use FFMpeg too).

Until the recent update, this extension was great and captured video within the documented restrictions (so 4*). Unfortunately, the recent update broke it completely and every attempt to record now fails with error message 'TypeError: The stream (in errored state) is not in the writable state and cannot be closed'. How can users revert to the previous working version and prevent update?

Your objective to make it dumber succeeded, it's now so dumb it doesn't work at all. :(

seems great, but unfortunately cant hear audio whilst recording (audio still comes through on preview)

.. updated to 5 stars following response :) yet another mozilla bug gone unfixed...

the user interface is... let's just say not robust but if you mouse over the buttons you can figure out what everything does. Other than that, seems to work great.

Hello, thank you for your addon, it works pretty well. I have only one issue: when I open the video in preview the option "Save video as" is unavailable.

Works great on short videos (a few minutes long). But on long videos, it records all the way through to the end, but when you click the Download button, it processes for a very long time, then just stops, and there's no way to make it do anything, or get the video. I tried 2 videos of about 1 hour length, one on Youtube and one on another website, with the same result.

Clicking the record button doesn't do anything.

Does not work.

My first test of this add-on on https://www.ardmediathek.de went well: I was able to capture some minutes of the livestream.

I click the icon but nothing happens.

Hello,
I have recorded a radio audio stream (about 1 hour) and then I tried to download the file. Now it's stuck at the recording icon and seems not to respond.
I have not used the Preview button

Perhaps I misunderstood the purpose of this add-on... But it does nothing. I click the button and nothings happens. Neither on youtube nor on blabla.adobeconnect.com and not on any other website I tried.
