Firefox content process sandboxing with Capsicum: it’s alive! Work in progress, but I have WebGL and audio working :)

Was wondering for a month why Firefox on my laptop would forget my GitHub session (and some other sessions) after restarting. Turns out “Delete cookies and site data when Firefox is closed” got enabled somehow. Facepalm.

I was wondering why I can’t watch Twitch streams in Firefox… turns out they serve a broken player if your User-Agent does not contain Linux/Windows/macOS. Fail.

haha wow my SoundFixer addon is on the addons.mozilla.org front page

The best Cloud-to-Butt replacement I’ve seen yet, thanks to this page:

Butthole was released in 2016 for Firefox to make Buttflare captchas less painful

yay, Firefox will use SHM_ANON on FreeBSD now

LOL. MEGA says “use Chrome to download large files because Firefox has a small buffer”. Opened in Chromium… “unzoom or use Firefox because of a zoom rendering bug in Chrome/ium” :D

haha, Phoronix wrote about the stuff I posted on wayland-devel@. So yeah, I’m working on Rust bindings for libweston that would eventually allow me to write the best Wayland compositor ever :)

And fractional HiDPI scaling was pretty easy to add. Wayland apps look awesome. However, X11 apps are blurry now, and bypassing the scaling for Xwayland is not as easy… So I made some changes to my Ports fork to enable Wayland support in more apps. Turns out a lot of complex applications run fine — LibreOffice (!), Inkscape, MyPaint, RawTherapee, Darktable.

The Firefox Wayland support though… is not usable yet :( It looks awesome but EGL isn’t working and, even worse, the screen doesn’t refresh when it needs to — so you’re typing and letters don’t appear until you scroll or some time passes. Hopefully this will be fixed soon.


Buffer more video: media.cache_readhead_limit = lots

Disable backspace-to-go-back to prevent accidental form loss: browser.backspace_action = 0

Warning on Ctrl-Q: browser.tabs.warnOnClose = true browser.showQuitWarning = true and DO NOT SET “Show my windows and tabs from last time”! Also, a WebExtension for this.

Wide gamut color: gfx.color_management.mode = 1

Save session less often: browser.sessionstore.interval = 60000

Kill safe mode prompt: toolkit.startup.max_resumed_crashes = -1

Force compositing acceleration: layers.acceleration.force-enabled = true

Force canvas acceleration: gfx.canvas.azure.accelerated = true (must create)

Smooth libinput touchpad scrolling and touchscreen on X11 (not needed on Wayland): MOZ_USE_XINPUT2=1

Faster mouse scrolling: mousewheel.default.delta_multiplier_y = 150

How to stop Firefox from making automatic connections

Wow, Opera 48 converts units, time zones and currencies on text selection. That’s really awesome.

SomeWebExtensionsattemptsimilar things but as there’s no native select popover thingy in Firefox, they either add a context menu item (okay) or just edit text inline (please don’t). At least they don’t inject custom UI into the page.
