auto-tab-discard VS gecko-dev

You might want to ask on developer of the addon: https://add0n.com/tab-discard.html

Not to be an enabler or anything, but have you tried Auto Tab Discard? Only active tabs will be loaded, so you can have thousands upon thousands of tabs without any impact on memory usage or performance.

I use Auto Tab Discard [0], which offloads tabs after a period of time. They still show as normal tabs (with a "ZZZ" icon to indicate it's been discarded), and the website reloads when I switch to them.

When I open the browser after closing it, the session is restored with all but the current tab offloaded so it opens quickly and using very little resources.

My current session has tens of tabs, only a handful of them active. It uses about .5% CPU when idle, and less than 1Gb RAM.

Also https://github.com/rNeomy/auto-tab-discard, which despite the name, doesn’t close tabs, it just unloads them from memory.

I'm using Auto Tab Discard for very fine control but it is not needed most of the time. FF does this automatically now via Tab Unloading

I think there is an issue open for this in the auto tab repo. Assuming that wasn't you who opened it you can go there and give a +1 to motivate the dev.

If something like Google Chrome is using a lot of power, can I determine which sites are using the most resources in its Task Manager (Shift+Esc)? Can I use something like Auto Tab Discard to minimize resource usage in tabs I'm not using?

I think this extension does something similar: https://add0n.com/tab-discard.html

You can see how Mozilla tests the compliance of their built-in elements in the Gecko repository (the ok and is assertions are defined in their SimpleTest testing framework). And here's the Web Platform Tests' reflection harness, with data for each built-in element in sibling files, that almost every browser pass.

Yes. https://github.com/mozilla/gecko-dev/tree/32c74afbb24dce4b5d...

aWheelInput.mDeltaY looks like the increment setting used for this https://github.com/mozilla/gecko-dev/commit/9033e3e1200acfd4b8f8ae024c215b99d12b97bdTried "mousewheel.default.delta_multiplier_y" and "mousewheel.with_control.delta_multiplier_y" without much luck.It may have something to do with https://bugzilla.mozilla.org/show_bug.cgi?id=1138704 although this case is about pinch zoom emulation.

You could add the feature by writing code to support is - https://firefox-source-docs.mozilla.org/setup/index.html

I checked Firefox monorepo, it has over 4x more C++ than Rust.

Are you leaving steps out or is your OP exhaustive? If you just straight up cloned release and that's it, start all over and follow https://firefox-source-docs.mozilla.org/setup/index.html for your OS
