    Our custom web browser no longer supports VideoJS. Rather than upgrade/build from scratch, we would like to simply fix that JS support. Our browser is forked from Firefox and not Chrome. Only people with experience in customising and building an XUL browser should enquire further.

    Hello everyone how are you doing? We are looking for a chrome extension developer. I will briefly explain my thoughts. You can share your screen when meeting with Google Meet and Zoom. Eventually you can use the extension to add stickers. For example, if I add 5 stickies, I want to exclude 2 stickies and only share 3. Sticky opening and closing is possible. This is a long term project and this feature is the first part of the project.
