I see two parts to OP’s question in the title. The first part is installing the extensions and the second part is configuring them. Firefox Sync will automatically install your extensions on a new device, but in the extensions that I’ve tested, the extension settings will not carry over.



My problem with AV1 is that so many people I talk to in real life about it think I’m mispronouncing AVI (Audio Video Interleave), the old container format that was popular in the 90s and early 2000s. I tell them it’s a video codec and they act all surprised like H.264 and H.265 are the only ones in existence.
