@teohhanhui @Gargron If there was a single button to permanently* disable the ad infrastructure then I would use it.

If there was a single button to permanently* disable all AI features I would use it.

And so on for other "features".

Using about:config to change the state of a list of switches to ensure that all AI is turned off, switches that may, at some point in the future be removed from about:config is not going to make me want to be a FireFox user again.

*as in disabled for evermore.

@Gargron I cannot really compare as I use Vivaldi as my primary browser with lots of tabs left open.

I use LibreWolf differently normally in private browsing mode for searches, route planning or reading the news.

Especially where a website makes you choose between accepting tracking or logging in.

I have other browsers installed for single uses - Chromium for Wire IM and nothing else.

I have noticed that the Helium browser (not using Helium services) feels much faster than Chromium.

@teohhanhui @Gargron The last straw for me was when Mozilla started building in infrastructure into Firefox to allow them to serve us users their ads rather than Google's et al.

Now we hear that Firefox is going to be a modern AI browser.

Some of Vivaldi must be open source but even if none of it is at least they have stated clearly that Vivaldi development does not include adding AI features.

Closed source + no AI vs FOSS + AI.

We all have to make our own choices in the end.
