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.
It's the Tor browser without Tor, there's a wipe button just for this issue.
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.
I tried to use Ubuntu for a bit but I just wanted to have regular Firefox with the built in updater, turns out this is way more of a hassle than it is on Windows.
It shouldn't be that hard to "install" a program like Firefox directly from a website but all you get is an archive thing that you have to manually "install" basically, it's tricky enough that someone wrote a tool just do do this: https://gitlab.com/Linux-Is-Best/Firefox-automatic-install-for-Linux
APT and Flatpacks are all cool but an offline installation should still be available and easy to use without being forced to use a terminal. Maybe I'm incorrect and I would love to hear about it but this is my experience.
Steam for whatever reason is basically installed the same way on windows as on PC in terms of user experience, you download a file and double click it. Maybe it's Mozillas fault? Who knows, it's frustrating in any case.
You can do this in any browser using uBlock Origin, just enable the built in Block Outsider Intrusion into LAN list in the Privacy category. (it's disabled by default)
Here it is if you wanna look at it: https://github.com/uBlockOrigin/uAssets/blob/master/filters/lan-block.txt (but no need to paste it into ublock, it's built in just disabled)
One thing that mastodon does is proxying all the media from the federated servers, lemmy does not do this.. (yet)
For example on this comment page there are 9 domains trying to connect directly to me according to ublock origin. I suggest blocking all third party requests on your instance using ublock origins advanced mode because the website works fine without them, it might be mostly avatars?
Just to clarify, those links at the bottom are from the description of the youtube video and OP didn't post em. For some reason that's what happens when you post youtube videos on lemmy (maybe adding your own descriptions stops this from happening? EDIT: yes it does)
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.
