Yay! :D

Glad they took the time to fix it.

You know what, I might have misunderstood what you was talking about. I was talking about when you type something into the url bar and it makes suggestions. You could arrow down to the next one, only a bug made it jump to the last one and then jump around. I missed the nagivate part somehow, so I think what you are talking about is something different. I'm sorry about that.

I can't say I am a big fan of this "claw back memory when you close a tab" feature, simply because I do not see significant benefits of it. I have 18 tabs open (no Flash or other memory hungry stuff) and it's eating about 2.8GB of RAM. If anything, the memory usage has increased.

You may want to check if one of your addons is not causing this or try new profile.Memory usage has improved so much.It must be something on your end that is causing so high usage.Or maybe there is a memory leak on particular site.

No. It's a memory leak with Firefox. It's always had it.

I hear people say that it's gone or I hear... "Why have so much ram if its not put to good use" bs all the time. There is no reason Firefox should be causing videos to stutter just because it's using over 1.5GB of ram... And yes, flash based videos do lag/stutter when Firefox uses a lot of memory. This is why it's a bad thing.

The only add-on I have is AdBlock Plus and I've created a new profile and it still happens.

Please check your addons, they maybe created Zombie Compartment, also how old is your profile, do some maintenance to it with this addon:

[/CODE]

Also make a new profile with new FF8 Beta or FF 7.0.1 with your likely addons and tell us for sure so if you find some bug, we can file it to mozilla.

What kind of sites are you on? I just counted and there are 30 tabs open and 12 extensions running and I was a bit shocked that Firefox was even using 600+ mb. It's usually doesn't go over 400mb for me, but I'm not on my own PC right now (although I have even more extensions installed on my PC).

The only time I had Firefox use over 2GB of RAM was when I opened a page from a Google search that had 300-400 images all around 3kx4k in size., It normally sits around 400MB for me, going up to 1GB or so when I really exercise it.

Edit: So if it's using 1GB+ regularly, check extensions and stuff, because that's not normal.

Another UI change is going to be in today's nightly: Bug 682534 - Implement conditional forward button for winstripe / large icons mode

(landing in the Linux and Windows builds today, Mac version later)

OK, so it is 19 tabs and FF is consuming ~2.6GB of RAM. The add-ons I have are:

- AdBlock+

- British English Dictionary

- DownThemAll

- Element Hiding Helper for AdBlock+

- FasterFox

- FlashGot

- LastPass

- Status-4-Evar

- TinEye Reverse Image Search

As you can see, not very many tabs, not very many add-ons, but the RAM usage is still sky-high.

https://addons.mozil...ox/performance/ might be interesting read. FasterFox has caused performance issue in Firefox for a while according to some. Please.. don't try to debate with me.. I don't know myself I'm just saying some have said so and maybe you should consider trying Firefox without it as testing. What I do is not use an addon unless I truely need it. Not just like using it. Just trying to help.

19 tabs? What are the bigger sites you use?

Depends what you mean by bigger sites, but I use Hotmail, GMail, BBC, Neowin, The Reg, Facebook, Twitter among the big ones.

I will try that. The firefox.exe process has been running for about 5 days now, so I wonder if memory leaked gradually over time.

I can't say what addon is causing havoc with your Firefox but on my system AutoPager addon and freewaregenius.com won't play nice and causes Firefox to eat 2gb ram and 60% CPU. So popular addons can definitely mess up Firefox.

Which specific version of Last Pass before 1.5 version has zombie compartment issue. Update all your addons.

Twitter, Facebook, Gmail and Hotmail are very dynamic sites and causes memory to gradually grow up. 5 days, its definitely Zombie compartment issue and memory leak. I suggest to go about:memory and click on GC, Minimize memory usage few times and also use addon Place Maintenance 1.0 and clean little profile.

Nightly install using about 223MB of ram, but I only have about three tabs open..

jemalloc enable on Mac OSX increased memory usage for all over OSes, so please be patient, they will fix this issue.

This is ABSOLUTELY dumb. I sincerely don't give a duck if it breaks a lot of extensions, that's a matter of developers. I rimember when an update broke an adblockplus functionality and caused firefox not to load some pages. Vladmir palant fixed the iussue in THREE days after the patch landed on nightly.

Its not all about addons, it was causing 100% cpu usage on single core processor. (I own quad core), so it was not issue for me but for many it was. It was far from perfect, I use it a lot but even then I think it was OK and let developer make it more polished and refined. I am enjoying new conditional forward button. Also here is good news:

    • BATorrent 3.0.2 by Razvan Serea BATorrent is a lightweight, open-source BitTorrent client built with modern C++ and Qt 6, offering a clean, fast, and privacy-focused alternative to traditional torrent apps. It supports magnet links, .torrent files, resume data, sequential downloading, per-file priorities, and even imports from qBittorrent. Power users benefit from integrated RSS auto-download with regex filtering, duplicate detection, and automatic tracker lists from Stremio. Streaming is seamless thanks to auto-detected players like VLC and IINA. BATorrent includes robust VPN tools—interface binding, auto-detection for WireGuard-based services like Mullvad and NordLynx, kill switch, proxy support, and IP filtering. A full WebUI enables remote control, while integrations with Plex, Jellyfin, and Emby automate library updates. With themes, speed scheduling, system-tray alerts, and cross-platform support for Windows, Linux, and macOS, BATorrent delivers a polished, high-performance torrenting experience. BATorrent features: Core .torrent file and magnet link support Resume data — picks up where you left off after restart Import torrents from qBittorrent Create .torrent files from any file or folder Sequential download mode Per-file priority control (skip, low, normal, high) Seed ratio limits with auto-pause DHT, PEX, UPnP, NAT-PMP RSS Auto-Download Subscribe to RSS feeds — automatically download new torrents as they appear Regex filters — match only what you want (e.g. 1080p|720p, S01E\d+) Per-feed settings — custom save path, check interval (5–1440 min), enable/disable Auto-download — matched items are downloaded automatically in the background Supports magnet links, .torrent URLs, and tags Tray notifications when items are auto-downloaded Duplicate detection — never downloads the same item twice Stremio Stremio Addon System pre-installed — works out of the box Auto tracker list from ngosang/trackerslist Streaming Play while downloading — stream video files before the download is complete Supports mp4, mkv, avi, mov, wmv, flv, webm, m4v, ts Auto-detects installed players (VLC, IINA, system default) VPN & Privacy Interface binding — lock torrent traffic to a specific network interface (e.g. tun0) Auto VPN detection — identifies VPN interfaces (tun, tap, WireGuard, Mullvad, NordLynx, ProtonVPN) Kill switch — automatically pauses all torrents if the VPN interface drops Auto-resume — resumes only the torrents paused by the kill switch when VPN reconnects Proxy support — SOCKS5 and HTTP proxy with optional authentication IP filtering — load P2P blocklists to block unwanted IP ranges Protocol encryption (enabled / forced / disabled) WebUI Remote management — control torrents from any browser at http://localhost:8080 REST API with JSON responses Add torrents via magnet link or .torrent upload Pause, resume, remove torrents remotely View peers and files per torrent Dark theme matching the desktop app HTTP Basic Auth with SHA-256 password hashing Configurable port and remote access (localhost vs 0.0.0.0) Interface 3 themes: Dark, Light, Midnight (bat/vampire aesthetic) Real-time speed graph Detailed panel with tabs: General, Peers, Files, Trackers Filter bar: search by name, filter by state (Active, Downloading, Seeding, Paused, Finished) Drag & drop .torrent files and magnet links Drag & drop reorder in torrent list System tray with notifications (download complete, kill switch events, RSS auto-downloads) Splash screen with bat animation Bilingual: English and Portuguese (BR), auto-detected from system locale Bandwidth Scheduler Alternative speed limits — set different download/upload limits on a schedule Time range — configure active hours (e.g. 01:00 to 07:00), supports overnight ranges Per-day control — choose which days of the week the schedule applies Automatically switches between normal and alternative speeds Media Server Integration Plex — automatically trigger library scan when a download completes Jellyfin / Emby — same automatic library refresh via API Configure server URL and authentication token/key in Settings System Cross-platform: Windows, Linux, macOS Auto-shutdown — automatically shut down PC when all downloads complete (60s cancellable countdown) Auto-update system (AppImage on Linux, installer on Windows, DMG on macOS) CLI arguments: pass .torrent files or magnet: URIs directly Keyboard shortcuts: Space to toggle pause, Ctrl+A to select all, Ctrl+O to open BATorrent 3.0.2 changelog: Phone pairing & WebUI The browser WebUI was reskinned to match the desktop app — same dark palette, Inter font, flat surfaces, the real BATorrent logo (it was a random bat before), and a proper magnet icon. It now looks like the same product, not a separate dashboard. Pairing is one tap and zero typing: the generated WebUI password is now copyable, and the QR code carries the credentials — scanning it from your phone logs straight in (no typing the IP or password), then drops the credentials from the address bar. Search Two new providers: RuTor (CIS sources, no login, via a public TorAPI relay) and Torrents-CSV. Results are sorted by seeders (healthiest first), and each search now times out after 15 s so one dead provider can't hang the UI. Files & trackers Per-file priority is back: right-click a file in the detail panel to set Skip / Low / Normal / High. Rename an individual file inside a torrent (double-click or the file menu), separate from renaming the torrent. Remove a tracker from a torrent (the ✕ on a tracker row); adding was already there. Smart Paste on Ctrl+V — paste a magnet, a 40-char info-hash, or a .torrent URL straight from the clipboard and it's added immediately (text fields still paste text normally). Covers & titles Anime fansub naming ([Group] Title - NN) now resolves to the right show. Audio channel layouts in titles (DDP5.1, 7.1, …) are stripped so they don't pollute cover matching. Under the hood The legacy QWidget interface is gone. QML had been the only UI since 3.0.0 (reachable old code lived behind a hidden --legacy flag); with parity confirmed, the entire QWidget layer — main window, every dialog, the theme manager — was removed (~13,400 lines). The four restored actions above were features that backend already supported but the QML port had never wired. macOS: the WebUI password hash moved out of the keychain into app settings, so launching the app no longer pops a login-keychain password prompt on unsigned builds. The actual password still lives in the keychain. Cleanup: ~400 orphaned translation strings and a batch of dead code removed; internal duplication collapsed; an ARCHITECTURE.md added for contributors. Unit / security / memory tests and the ASan/UBSan/TSan sanitizers stay green.
