I don’t know.

Things are missing there too. It should sync and take over everything.

I use it, but when I experimented with data synchronization using Firefox Sync, it simply doesn’t work, it is so unreliable and unpredictable that you can’t bet on it. It’s a real pity, because I wanted to use it for a cool thing, synchronizing data of one website, without having my own server for that website. It failed because Firefox Sync fails.

I recommend KDE Connect, it also has this function. :)
But sometimes I use this and sometimes I use that feature.

I have it too. The image randomly freezes or the entire playback freezes.
But also regular video (not live) has problems, for example it skips forward a few seconds at random moments.
I don’t know if this is something to report on bugzilla. It’s hard to report this because I would have to constantly record my screen while watching YouTube to catch the random moment when it happens.

I have uBlock and SponsorBlock. I’m on Arch Linux.

My own:

A link to a magazine or collection always takes you to /m, instead of e.g. /*, which is where I am currently.
Links from Lists take you to /m, /* or m/.../microblog, depending on where I am currently.

The script does not work in the Polish language version of kbin.

Not only. This also happens when switching between TTYs.

I’m trying to move the setting to the boot stage, but it’s not easy.
