pocket.enabled to false

First thing I do every clean install

[–] [email protected] 5 points 11 months ago* (last edited 11 months ago) (1 children)

Thanks, I need to remember to do this tomorrow.

Just had to entirely do a fresh install like 6 hours ago.

[–] [email protected] 8 points 11 months ago

Just did it now, thanks for reminding me! 😊

Disables the builtin Pocket extension.

[–] [email protected] 3 points 11 months ago

I looked up "pocket.enabled" in about:config, but there wasn't an entry by that exact name. There was "extensions.pocket.enabled" though. Is that the same?

Setting full-screen-api.warning.timeout to 0 removes the notification at the top of the screen that tells you how to exit fullscreen mode.

For me:

browser.ctrlTab.recentlyUsedOrder: False

browser.tabs.insertAfterCurrent: True

dom.popup_maximum: 100

browser.download.improvements_to_download_panel: False

[–] [email protected] 11 points 11 months ago

browser.tabs.insertAfterCurrent: True

I use this too. Great feature for tab hoarding keyboard warriors like me. Use Alt/Cmd + 9 to jump to the last tab.

dom.popup_maximum: 100

What does that do?

browser.download.improvements_to_download_panel: False

Why?

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

extensions.pocket.enabled -> false
Disable Pocket

identity.fxaccounts.enabled -> false
Disable Firefox account

media.autoplay.blocking_policy -> 2
You have to click the play button to play videos.

media.peerconnection.enabled -> false
Disable WebRTC

[–] [email protected] 25 points 11 months ago (2 children)

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

[–] hal_5700X 7 points 11 months ago

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

[–] mea_rah 4 points 11 months ago (2 children)

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.

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

hello brother

[–] [email protected] 2 points 11 months ago (1 children)

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

[–] hal_5700X 2 points 11 months 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 11 months 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?

[–] hal_5700X 3 points 11 months ago* (last edited 11 months ago) (1 children)

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

[–] [email protected] 2 points 11 months ago (1 children)

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

[–] hal_5700X 13 points 11 months 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.

[–] [email protected] 2 points 11 months ago

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

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 ☹️

[–] [email protected] 1 points 11 months ago (1 children)

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

browser.self_destruct_shortcut -> disabled

gets me everytime

[–] [email protected] 4 points 11 months ago (1 children)
[–] [email protected] 8 points 11 months ago

now when you press Ctrl+D it does not self destruct the computer

[–] [email protected] 17 points 11 months ago

If you're lazy, librewolf is hardened firefox (sometimes it can break sites though)

[–] [email protected] 12 points 11 months ago

I like resistFingerprinting = true but it may be a bit much for some people. You lose some keyboard hotkey capabilities in RES and all your windows always open at a certain size upon relaunch/new window.

[–] Crul 10 points 11 months ago* (last edited 11 months ago)

I have a slow connection, so privacy.partition.network_state = false was a game changer. It prevents firefox to re-download an image (or video, or whatever) when you open it in a new tab (State Partitioning in Mozilla docs).

Warning: the main goal of State Partitioning is to prevent cross-site tracking, so this option will make that easier. In my case it's worth it and I mitigate that by other means, but you should be aware of it.

[–] [email protected] 8 points 11 months ago

dom.event.clipboardevents.enabled - block sites from preventing you using copy+paste e.g. in email and password fields.

I've only recently started using this one, so ask me again in a couple of months if it solves the issue :] or if it has unwanted side-effects - I know at least it doesn't prevent websites interacting with the clipboard entirely e.g. with a button to click to copy text to the clipboard

[–] [email protected] 8 points 11 months ago (2 children)

Not obscure but general.smoothScroll.msdPhysics.enabled=true is a must have IMO.

[–] overtinker 4 points 11 months ago (1 children)

Sounds fancy. What does that do?

[–] [email protected] 4 points 11 months ago (2 children)

You have to actually toggle to see it but IMO it massively improves how scrolling feels.

There are a few more scrolling-related options out there on the net if there's a particular "feel" you want to go for. https://github.com/yokoffing/Betterfox/blob/main/Smoothfox.js provides a couple you can try out, and most of these custom scrolling options use msdPhysics as a baseline.

[–] davetansley 2 points 11 months ago

I just switched from Chrome today and I was wondering how to improve the scrolling (it felt heavy and slow). This setting seems to have worked wonders! Thanks!

Backspace behavior: 1 something like that. Sets backspace to go to previous page it was once default but it is not anymore

[–] [email protected] 12 points 11 months ago (1 children)

Browsers changed this because people kept accidentally hitting it. I'm glad it's gone. My mouse has back/forward buttons on the side and I remapped those to go back and forward in browser history.

[–] [email protected] 6 points 11 months ago

Yeah i think someone might hit it accidentally i think it is a good decition to have it disabled by default but i still like it a lot and it is great to have a way to set it how i like it

[–] emptyother 3 points 11 months ago

Really, its gone? I think I still got the command that disables the back keybind in my user.js file. Now I can remove that line.

I always like to start over with a clean slate. The one that's been with me for about 15 years now is browser.tabs.closeWindowWithLastTab set to false.
