Microsoft Edge: Discard / freeze all background tabs

edge_discard_tabs.js

Sir/madam this is taken by Gist has akin// For tab hoarders using Microsoft Edge (this might work on other Chromiums, but I haven't tested)
// who keep so many tabs that even edge://discards/ page becomes unresponsive.
// Can discard/freeze all background hidden tabs. Foreground (visible) tabs, tabs playing audio,
// and tabs in the "Never put these sites to sleep" list will not be discarded/frozen.
// In the address bar, enter: edge://discards/discards.js 
// Then open DevTools (Ctrl+Shift+I or F12), go to Console, and paste the following code.

await (async () => {
    
    // To freeze tabs, set to false; to discard tabs, set to true
    const DISCARD_INSTEAD_OF_FREEZE = true;
    
    // Change this if you want to prevent the last X active tabs from being frozen/discarded
    const TAB_PRESERVE_COUNT = 0;
    
    // The "cannot freeze reasons" containing the following words will be ignored
    // Other reasons, such as "the tab is emitting audio", will be respected so background players won't be closed
    const ignoredWords = ["BrowsingInstance", "IndexedDB lock", "notification permission", "WebLock"]
    
    let discards = await import("//discards/discards.js");
    let provider = discards.getOrCreateDetailsProvider();
    let tabinfos = (await provider.getTabDiscardsInfo()).infos;
    const reasonNotIgnorable = reason => !ignoredWords.some(word => reason.includes(word));
    for (let i = 0; i < tabinfos.length - TAB_PRESERVE_COUNT; i++) {
        let tab = tabinfos[i];
        if (tab.loadingState == 2 // loaded
            && tab.visibility == 0 // hidden
            && tab.isAutoDiscardable
            && (DISCARD_INSTEAD_OF_FREEZE || tab.state == 0) // active (do not freeze if already frozen)
        ) {
            if (tab.cannotFreezeReasons.some(reasonNotIgnorable)) { // not ignorable reason
                console.log(`Tab ${tab.id} ${tab.title} cannot be ${DISCARD_INSTEAD_OF_FREEZE ? "discarded" : "frozen"} because: `
                    + tab.cannotFreezeReasons.filter(reasonNotIgnorable).join(", "));
            } else {
                if (DISCARD_INSTEAD_OF_FREEZE) {
                    provider.discardById(tab.id);
                    console.log(`Discarded tab ${tab.id} ${tab.title}`);
                } else {
                    provider.freezeById(tab.id);
                    console.log(`Frozen tab ${tab.id} ${tab.title}`);
                }
            }
        }
    }
