Felix Mikolasch, data protection lawyer at noyb: “Mozilla has just bought into the narrative that the advertising industry has a right to track users by turning Firefox into an ad measurement tool. While Mozilla may have had good intentions, it is very unlikely that ‘privacy preserving attribution’ will replace cookies and other tracking tools. It is just a new, additional means of tracking users.”

Sigh… I cannot for the life of me figure how anyone could think that enabling PPA (even by default) means that advertising industry has somehow right to track folks. Like dude, the entire point of PPA is that advertisers could then get to know if/when their adverts are working without tracking people.

The argument that “It is just a new, additional means of tracking users” also doesn’t really make sense - even if we assume that this is new means of tracking. I mean, sure it technically is new addition, but it’s like infinity+1 is still infinity - it doesn’t make a difference. The magnitude of this one datapoint is about the same as addition of any new web api (I mean there are lots that shouldn’t exist - looking at you chromium… but that’s besides the point).

File a complaint over use of third-party cookies and actual tracking if you want to be useful - this complaint just makes you look like an idiot.

Also, Servo was originally more or less a testbed for new rendering pathway (webrender) which, when ready, was then integrated into Firefox.

True, and I agree - for this feature to be effective the site-specific rules need to be maintained properly.

All I’m saying is that it leaving some query parameters unremoved is not indicative of the feature not working. If you want to add more query parameters to the removed list then feel free to open a bug about it.

That feature removes parameters that are known to be used for tracking. It does not remove all query parameters willy-nilly. For example on youtube it should remove si, feature and kw parameters as well as a set of parameters on a list that applies to all websites. However, pp parameter is not in that to-be-removed list.

As an example v parameter is for video id on youtube, it would be kinda silly if that was removed, so the feature kinda has to do some site specific action.

I’m not seeing any such issue with Nightly on my Fedora system.

Well the feature development is certainly progressing - here is the tracking bug for it.

You can nowadays just test it in normal nightly without special build - it’s extremely incomplete, but you can test it if you wish. It’s tied to revorked sidebar which you need to enable in about:config.

Yeah, history is extremely valuable feature. I think I would rather get rid of bookmarks and maybe even tabs rather than history.

In that case the issue is likely that files on disk are being modified by whatever mechanism your IT uses to push updates to devices. If the program files are modified while Firefox is running then you will unavoidably get this prompt.

I suppose the best you can do is to ask your IT folks to not update programs that are currently running.

I have no clue about hacking macOS

Take this with a grain of salt, but I believe I’ve read that standard backdrop-filter won’t work here and this would instead require OS compositor level mechanism because menupopup and panels are technically separate windows (or window-like widgets) from OS perspective.

You just have the link texts in a text editor one at each line, then select all and drag the selection to tabs toolbar.

But yeah, it does become an issue if you try it with thousands of tabs… It should work, but probably chokes quite a bit.

I guess that kinda depends on what you mean by “upload”. If you simply mean if user can point the extension to load some local file eg. via <input type="file"> then sure, that works just fine.

It sounds like the issue you mention regarding uBO Lite is not about if it can read a local file, but rather that it can’t use that data to update the active filter lists - perhaps because it already has too many dynamically inserted filter rules, but that’s just a guess.

Right, but then you shouldn’t be shocked to find out that a feature was removed because nobody seemed to be using it.

IIRC the old tab groups feature was eventually removed because telemetry showed that only very few people used it…

I mean, do whatever works for you, but that sounds kinda unnecessary when you can just use an already existing feature - tabs.

Not at all the same thing. For one, you can open a history entry and then navigate back from that to the page you came from to that page - which there may be several. Tabs preserve per-tab history which makes it superior in many ways to both history and bookmarks.

My first guess would be that this is caused by the website implementing its own navigation/history behavior using History API. That can easily mess things up, or at least not behave like you might want.

Okay, since it doesn’t like it’s your main computer or anything, you might be interested to try taskbar profile grouping. Go to about:config and while there create a new boolean pref named taskbar.grouping.useprofile and set it to true. Doing that the two profiles should have their own group in taskbar. It’s a very crude feature though, since for example the right-click jump list items are not separate and you can’t set different icons for them (unless you do that via Windows somehow), but it sort of works.

Fair. For something like that containers don’t work, and indeed profiles are probably the way to go. I sure wouldn’t mind if about:profiles had a button to create new icon for that specific profile which then would also be in its own taskbar group, but I doubt I would want it as default for new profiles.

At any rate, having multiple profiles per same install on same Windows user poses some issues. Like what profile are links in other applications supposed to open in?
