Chrome's extension ecosystem consolidated hard in 2025. The Manifest V2 shutdown forced every major extension to rebuild from scratch or die — and a lot of them died. uBlock Origin shipped v1.70.0 on MV3 in mid-2025. Great Suspender's original repo is still abandoned (it was compromised back in 2021), but multiple forks carry on. Session Buddy updated. Toby, Cluster, and several tab organizers quietly disappeared from the store. The market looks very different from two years ago.
What's worth knowing right now: the MV3 transition limited some extension capabilities in concrete ways. Dynamic rule updates for ad blockers are capped at 30,000 rules (with up to 330,000 static). Content script injection timing changed in ways that broke extensions relying on document_start injection. Extensions that used webRequest blocking had to rewrite entirely around declarativeNetRequest. Some handled the migration well; others quietly shipped degraded versions without disclosing what changed.
For tab management extensions, Chrome's side panel API (available since Chrome 114) opened real surface area that the best extensions in 2026 now build around. Popup-based tab managers feel dated compared to persistent side panel implementations.
One framework worth applying before installing anything: does this extension solve a problem Chrome's built-in features cannot? Memory Saver handles basic tab suspension. Tab groups handle basic organization. Native vertical tabs arrived in Chrome 146. The extensions worth installing in March 2026 are the ones filling genuine gaps, not re-implementing what Chrome already does.

Frequently Asked Questions
Is uBlock Origin still available for Chrome in 2026?
Yes. uBlock Origin migrated to Manifest V3 and released v1.70.0 in mid-2025. It is still available on the Chrome Web Store as of March 2026. The MV3 version uses declarativeNetRequest with up to 330,000 static rules, which covers most blocking needs though some advanced dynamic filters require the companion uBO Lite or workarounds.
Is Great Suspender safe to use in 2026?
The original Great Suspender extension was compromised with malware in early 2021 and removed from the Chrome Web Store. As of March 2026, several community forks exist (The Great Suspender, The Marvellous Suspender) that have been audited and are safe, but you should install from the linked fork repositories rather than searching the store blindly.
What did Manifest V3 actually break for Chrome extensions?
MV3 removed blocking webRequest — extensions can now only observe network requests, not modify them in-flight. Ad blockers had to move to declarativeNetRequest with rule limits. Background pages became service workers, which means extensions can no longer run persistent background code. As of mid-2025, MV2 extensions no longer load in Chrome 135 and above.
What is the best OneTab alternative in 2026?
OneTab saves open tabs as a list to free RAM, but stores everything in extension sync storage (5MB limit) and has had privacy policy concerns. As of March 2026, the most commonly recommended alternatives are SuperchargeNavigation (workspace snapshots, local storage), Session Buddy (JSON export/import), and the built-in Chrome tab groups save feature for simple use cases.
