It is possible that some extensions can cause issues while starting up or using Clipchamp. We've seen related issues in Firefox, Safari and Chrome.
We're working on measures to prevent any interference but some problems are out of our hands and require the plugin or extension developers to make changes on their end.
If you encounter any problems while using Clipchamp that you think might be caused by a browser addon, for instance the video conversion process might not start or is idling without making progress, please get in touch with us at firstname.lastname@example.org. Please let us know which browser extensions you have installed so we can investigate the issue.
We also published a blog post that delves into the topic in a bit more detail, in particular focusing on Chrome extensions.
