Youtube is not ahead as of now, you can check on this website: https://drhyperion451.github.io/does-uBO-bypass-yt/ It also links to a guide.
Only reason they are seeing so many uninstalls is because ublock origin is the big one that works and that requires uninstalling other blockers to get it to not be detected.
Ublock origin doesn't track uninstalls but it has gained quite a few users in the last 8 days

Some day they will offer linux version that you can download from from the website and install without using terminal.
Mullvad is a fork of Tor Browser so it gets some features from that like:
Discussion about this https://github.com/mullvad/mullvad-browser/issues/1
It's not a replacement for Firefox or it's forks, it's a complement to your main browser. It's like private browsing but always private and always separate from your other browsers and won't save any data locally except maybe bookmarks.
The link I originally posted should explain this but here is a page that explains it in greater detail: https://mullvad.net/en/browser/hard-facts. Some more links:
It's the Tor browser without Tor, there's a wipe button just for this issue.
This might be a better suggestion then: https://mullvad.net/en/browser
Useful even without a VPN.
Good thing that you can still self host it, post your favorite jitsi instances below for everyone to use.
I'll start with this one: https://calls.disroot.org/
Only the last three or so windows though, so if you got a few pop-ups before you press that you might be screwed...
...unless you have backups of an old session file, then you can use this tool to restore a list of those tabs: https://www.jeffersonscher.com/ffu/scrounger.html
There is also this handy addon for saving backups of windows like that to a txt list of urls: https://addons.mozilla.org/en-GB/firefox/addon/urls-list/
Easiest way to stop this from happening is to use ublock origin to block all third party request on your instance.
One way to do this is via dynamic filtering. This is for advanced users so be sure to read the info page: https://github.com/gorhill/uBlock/wiki/Dynamic-filtering
(Consider backing up your ublock settings before doing this)
If you are using lemmy.ml your rule would be this:
lemmy.ml * 3p block
if you're using another instance then change the domain or use both rules cause you might end up visiting the others as well. Note that adding this rule wont work unless enable advanced features in ublock origin.
EDIT: THIS MIGHT BREAK THINGS ON YOUR INSTANCE, its recommended to learn how to use dynamic filtering to unbreak it: https://github.com/gorhill/uBlock/wiki/Dynamic-filtering:-quick-guide If it breaks stuff just remove that rule.
You could also block it using static filters but I can't remember how to do that exactly, if you know please reply below.
There seems to be some bugs with federation here and there.. for example there are lots of interesting communities you can subscribe to, here are some of them: https://lemmy.one/communities/listing_type/All/page/1
These will all work and they would show up on your front page if you enabled your front page to work like that in your settings. However some are mastodon accounts and who knows what else, it's not super clear.
https://lemmy.ml/communities and https://beehaw.org/communities has some nice communities that I might wanna subscribe to but and sometimes you can just search for [!firefox@lemmy.ml](/c/firefox@lemmy.ml) locally and it works. like this:
https://lemmy.one/c/firefox@lemmy.ml
and you would think this should work: https://lemmy.one/c/gaming@beehaw.org
but 404.. can't search for it either.
Maybe that instance disabled federation in some way? Maybe this instance is too new so the other one has to allow it? it's unclear.
Lemmy seems real cool and it should work fine for local discussion just like any subreddit but federation might be sorta fuzzy..
