I'm trying to import my bookmarks from an HTML file. They say to click the menu button but there is NO menu button with 3 horizontal stripes. I'm using a Chromebook laptop.

Able to sign in to Mozilla account, but cannot find Sync anywhere. Sync is OK on multiple other devices. System also seems unable to load 140.10 esr. Is it possible to sync on esr versions?

I recently upgraded from Ubuntu 24.04 to 26.04, using Mate Desktop and Compiz compositor. I am using Firefox from the Mozilla Team PPA, currently 150.0.1. I am running custom kernel built from upstream source, currently 6.18.25. Hardware is a home brew CoffeeLake machine, i7-9700k, 64G of RAM, 2TB WD Black SSD and many TB's of spinning rust, graphics is Intel ARC B50 Pro, ASUS XONAR SE 5.1 Channel 192kHz/24-bit Hi-Res 116dB SNR PCIe Gaming Sound Card. Prior to upgrading Firefox was not 100% occasionally tabs would wedge, now if I get two hours I'm doing good, I've tried disabling extensions and plugins no help. Tried with and without hardware decoding, worse without but bad no matter. Any suggestions how to get stability back?

• • Background:**

I'm a senior software engineer running Firefox Developer Edition on a Linux machine with 8GB RAM. I have Fission architecture (site isolation) enabled, which I understand is now the default since Firefox 95+.

• • The problem:**

When I open 20 or more tabs across different domains, Firefox's memory consumption scales dramatically — often reaching 4–6GB of RAM for what should be lightweight browsing sessions. This is significantly higher than what I observed before Fission was enabled.

• • What I've already tried:**

- Disabled hardware acceleration → no significant improvement - Set browser.tabs.unloadOnLowMemory to true → partial relief

 but tabs reload constantly, disrupting workflow

- Reduced content.notify.interval → marginal improvement - Tested with all extensions disabled (safe mode) → RAM usage

 still high, confirming it's not extension-related

- Checked about:memory → large number of separate

 "Web Content" processes, one per origin as expected with Fission

• • What I'm trying to understand:**

1. Is there a way to set a maximum process count cap for Fission

  without fully disabling site isolation? I found 
  dom.ipc.processCount but changing it doesn't seem to affect 
  Fission's per-origin process spawning behavior.

2. Is browser.tabs.min-warm-process-count a relevant setting here

  and what is the safe range to modify it?

3. Does Firefox have a built-in memory pressure threshold where

  it automatically consolidates processes — similar to Chrome's 
  memory saver — and if so, which about:config keys control it?

• • Environment:**

- Firefox Developer Edition 151.0b10 - OS: Ubuntu 24.04 LTS - RAM: 8GB - Fission enabled: confirmed via about:support - Extensions: disabled for testing

Hello, I use Firefox 150.0.1 on Linux Mint 22.3. I want to use the VPN integrated in Firefox but I don't see the VPN icon in the toolbar. How can I use the integrated VPN in this version of Firefox ? Thanks for your help.

The quick links on the home page should be exactly for that QUICK LINKS! not for visited sites! also you only have four rows. OPERA have unlimited. To make matters worse, the stupid sites that I visited only once cannot be removed.

When I click a link multiple Firefox windows open all with the profile select. I close them one by one but clicking the link again opens the same five windows. Where is this behavior stored?

Would it be possible to extend the "Delete cookies and site data when Firefox is closed" to not delete cookies from any domain stored in a bookmark? (I don't want to delete those as I'll get logged out/lose my preferences etc)
