We've all turned off trimURLs but what else is hiding in there?

The firefox account is actually neat. It syncs bookmarks, history and passwords between desktop, phone, laptop or wherever you use firefox.

[–] [email protected] 7 points 2 years ago

I manually backup my bookmarks. Firefox is set to delete history when I close it. For passwords I use KeePassXC.

It might still be useful to turn it off in some scenarios. For example you might not want firefox bothering you with the account on work PC where it might be against company policy to use the cloud sync.

Sure, but I only use it on my personal devices...

[–] [email protected] 1 points 2 years ago

Yeah, I was just pointing out that the setting might be still useful for some FF users.

  • Mention 5 obscure about:config params to change without explaining them
  • Refuse to elaborate

hello brother

What do browser.tabs.tabmanager.enabled and media.peerconnection.enabled do?

[–] [email protected] 2 points 2 years ago (1 children)

media.peerconnection.enabled it disable WebRTC.

browser.tabs.tabmanager.enabled it removes the tab manager. The down facing arrow next to the minimize button at the top right.

[–] [email protected] 7 points 2 years ago (2 children)

media.peerconnection.enabled it disable WebRTC.

Why would you want that? Doesn't that block you from using basically any online call?

[–] [email protected] 3 points 2 years ago* (last edited 2 years ago) (1 children)

I don't do online calls. Yes, it does block you from making online calls.

[–] [email protected] 2 points 2 years ago (1 children)

And why would you want that disabled besides not requiring it?

[–] [email protected] 9 points 2 years ago

WebRTC leaks your IP allowing third-party websites to exploit the WebRTC in your browser to detect your real IP address and use it to identify you.

You still can use desktop apps to do that.

Personally I have a separate Ungoogled Chromium installation for online calls, since some of those call/conferencing services kick up a fuss when launched inside Firefox ☹️

Why not set to 5 for media.autoplay.blocking_policy ?

[–] [email protected] 1 points 2 years ago* (last edited 2 years ago)

You have to click the play button to play the video. If you set it to 2.

EDIT Here's a Mozilla wiki article about it.

EDIT 2 You're talking about media.autoplay.default. That controls if autoplay is on or off and what is blocked, Audio only or Video & Audio.

[–] [email protected] 1 points 2 years ago (1 children)

media.autoplay.blocking_policy -> 2

This one breaks twitch for me. It doesn't let me unmute.

[–] [email protected] 1 points 2 years ago

Then enable auto play on twitch only. You can enable site by site and disable globally.
