I'm not tellin' ๐
Just pushed a small update that added SoundCloud to the filter options. Click the ellipsis (...) in the menu bar. It's under the Music & Audio filters.
Refresh the page to access it in NostrGram.
Try out NostrGram at https://nostrgram.co/

Correct. Play a podcast or a video or music as you browse around.
Knut's great. I loved the grilling. He's funny as hell too lol
SoundCloud embeds are now live in NostrGram. Refresh the page to get the update and check out #[0]'s profile and his podcast links to try it out. You won't be disappointed!
Are you using Safari as the browser? If so, don't. Use Chrome or Edge or something Chromium-based. Safari has myriad issues that make it very difficult to support as a software developer.
Nostrgram's creator, Jonathan Leger, is on deck for this episode of the Bitcoin And . . . Podcast. Inside you will find out more about cults (spoiler, we're in one and it isn't Bitcoin); How nostr works; what nostr clients do; and where we are going.

This post reminded me that I needed to embed SoundCloud in NostrGram. ๐
Testing SoundCloud embeds for next update.

I wouldn't recommend browsing #[0]'s profile page in NostrGram while hungry. ๐

NOSTRGRAM UPDATE:
* Pinned notes. Click on the thumbtack icon to keep a note in the lower-right corner of the screen. Great for playing video/audio while you read and post on NostrGram.
* LN zaps menu shows when you click on the profile LN icon (previously it just copied the profile's LN address)
* SVG images are now supported both for uploading and displaying in notes

NOSTRGRAM UPDATE COMING TONIGHT:
PINNED NOTES
If you want to watch a video or listen to some audio that's in a note but want to keep it handy so you can pause/mute/stop it at any point, you just click the Pin icon on the note and it will remain in the bottom-right corner of the screen until you click the pin icon again. This update is for desktop only.
I'll be pushing this update tonight. Just adding a few more things before I do so.

NostrGram.co shows you the relays. Login, search for the note ID and click the information icon in the upper right corner. At the bottom of the event structure it shows the relay list. 
Ok thanks for the feedback. I'll tinker with it in FireFox.
Livestreams (on YouTube anyway) use the same link that any other video does, so posting the video link should work.
Hmm.. Ok. I'll test more with FireFox. The app's primary target are Chromium-based browsers (Chrome, Edge, Opera, etc) but it should work with FireFox. Does it slow down at any particular point or just right after you login?
What exactly do you mean that it was "locking up on you"? Can you provide some detail so I know what went wrong? Also, what browser are you using?
