Performance
Stop Chrome reloading tabs, cut session RAM 70-75%, and block scripts that burn CPU. Tab suspension and network-level blocking, tested — free core tools.

You click back to a tab you opened an hour ago and watch it reload from scratch — scroll position gone, the form you half-filled wiped. That reload is Chrome's Memory Saver doing its job: it discards a tab's renderer process after about five minutes of inactivity, then reloads from the network when you return. On a machine under memory pressure it is the difference between a responsive browser and a crawling one.
Chrome's process-per-tab design is why memory matters. Each tab is a separate process; 30 tabs plus a handful of extensions can hold 4–6GB before any app opens. Suspension is the highest-leverage fix because a suspended tab drops from 150–500MB down to under 1MB while staying visible in the tab strip. SuperchargePerformance uses chrome.tabs.discard() to do this on a schedule you control, auto-protects 25+ stateful apps so they never reload mid-task, and reports a typical 70–75% reduction in session RAM.
The second lever is what runs inside each tab. Ad and tracker scripts keep working in background threads after a page loads, burning CPU and holding memory. Blocking them at the network request layer — SuperchargePerformance ships 186K+ rules across 22 sources in 3 tiers — stops the requests before the renderer ever sees them, freeing memory across every open tab at once. It runs with zero telemetry; the free core covers all of this, with a one-time $29 PRO tier.
Match the fix to the pain: tabs reloading means tune suspension; sluggish pages mean block scripts.
Which Browser Uses the LEAST RAM in 2026? Real Data Compared
Firefox 151 wins at high tab counts, but Chrome 149 with tab suspension drops to ~2GB and beats every browser. Real RAM figures at 10, 30, and 50 tabs.
How to Auto-Close Chrome Tabs (Suspension Is Better)
Tab Wrangler auto-closes tabs after a timer. But suspension frees the same RAM while keeping tabs in the bar. Here's when each approach makes sense.
Firefox vs Chrome RAM Usage: What the Data Shows (2026)
Firefox uses less RAM than Chrome at 30+ tabs — Gecko's 8-process cap vs Chrome's per-site isolation explains it. But Chrome with tab suspension beats both.
STOP Chrome Reloading Tabs When You Switch Back (2026 Fix)
Chrome reloads tabs because Memory Saver discards them after 5 min. Add sites to the exception list in 30 seconds — or suspend tabs smarter with an extension.
Frequently Asked Questions
Why does Chrome reload tabs when I switch back to them?
Chrome's Memory Saver discards inactive tabs after about five minutes to free RAM, then reloads them from the network when you return — losing scroll position and unsaved form data. As of June 2026, you can add specific sites to the exception list in chrome://settings/performance, or use an extension that lets you whitelist stateful apps so they are never discarded.
How much RAM can tab suspension actually save?
A lot. An active tab uses 150–500MB; a suspended tab uses under 1MB while staying in the tab strip. As of June 2026, SuperchargePerformance reports a typical 70–75% reduction in session RAM by discarding idle tabs with chrome.tabs.discard(). The savings are larger on ad-heavy pages, where background scripts can push a single tab past 500MB.
Does ad blocking improve Chrome performance?
Measurably. Ad and tracker scripts keep running in background threads after a page loads, consuming CPU and RAM. Blocking them at the network request layer stops the requests before the renderer processes them. As of June 2026, SuperchargePerformance applies 186K+ rules from 22 sources across 3 tiers, which frees memory across every open tab rather than just hiding elements after they load.
Will suspending tabs break apps like Figma or Google Docs?
Only if they get discarded mid-task — which is why stateful apps need protecting. As of June 2026, SuperchargePerformance auto-protects 25+ apps across productivity, media, and calls so they are never suspended out from under you. A discarded tab reloads from the network and loses unsaved state, so Figma, Docs, and similar tools should always be on the protected list.
Is there a free way to reduce Chrome memory usage?
Yes. Chrome's built-in Memory Saver (chrome://settings/performance) discards idle tabs at no cost. As of June 2026, SuperchargePerformance offers a free core with configurable suspension, 25+ auto-protected apps, and network-level ad blocking; an optional one-time $29 PRO tier adds more. Both run with zero telemetry, so neither sends your browsing data anywhere.
