Memory Optimizer — Tab Sessions & Password Vault

Free memory by discarding idle tabs, save and restore tab sessions, and keep an encrypted local password vault.

Memory Optimizer is three tools most people run separately, combined into one local-first extension: a memory cleaner, a tab-session manager, and an encrypted password vault with autofill risk checks — with nothing running that you didn't ask for. FREE UP MEMORY, HONESTLY See exactly how much RAM is available and what's holding tabs open — pinned, playing audio, protected, or just used a moment ago. Run a cleanup with one click and Memory Optimizer discards idle background tabs to free real memory, and clears the cache, cookie, and storage categories you choose. Every run is logged, so "did that actually do anything" has a real answer instead of a guess. NEVER LOSE A BROWSER SESSION Save your open tabs as a named, tagged session — a client project, a research binge, a personal-admin sweep — and restore the whole window in one click, whenever you need it again. Sessions are searchable, taggable, and exportable to JSON if you want your own backup. Built-in duplicate detection flags sessions that overlap so your library doesn't quietly fill up with near-copies. A PASSWORD VAULT THAT ONLY ASKS FOR WHAT IT NEEDS Store credentials in a vault encrypted with AES-256 under a master password you set — never stored in plain text, never sent anywhere. Before autofill ever fills a password in for you, Memory Optimizer checks the page for domain mismatches, typosquatted lookalike domains, and known-breached passwords (via Have I Been Pwned's k-anonymity API, which never transmits your actual password), and shows a clear Safe, Caution, Block, or Danger verdict before you type. A password-health view flags weak and reused credentials across your vault so you know exactly what to rotate. PERMISSIONS THAT MATCH WHAT YOU'RE ACTUALLY USING Most extensions like this ask, on install, to "read and change your data on all websites" — even if you only ever wanted the memory cleaner. Memory Optimizer doesn't. Website access for autofill, and network access for the three optional security checks (Safe Browsing, Have I Been Pwned, domain-age lookups), are requested only when you turn those specific features on — not at install, and not for everyone. Decline any of them and the rest of the extension works exactly the same; you just won't get autofill or the online risk checks for that feature. WHAT RUNS LOCALLY, WHAT DOESN'T Your sessions, cleanup history, and vault entries are stored in this browser's local IndexedDB — not on a server. Cloud sync exists as an optional, off-by-default feature for people who explicitly want to sync across their own devices; nothing is uploaded unless you turn it on. There is no advertising and no analytics that identify you. WHO THIS IS FOR Anyone running a browser with dozens of tabs open, anyone who reuses passwords more than they'd like to admit, or anyone who has ever lost a perfectly organized set of tabs to an accidental window close. Memory Optimizer is built to be the extension you forget is running — until the moment it saves you. Feedback and bug reports: support@nhrsoft.com
