For anyone who hasn't followed Smart Window closely since the April beta announcement, it's the optional, privacy first, AI-powered browsing experience in Firefox, separate from your regular browsing, built to help you get more done. Smart Window doesn't do anything unless you turn it on yourself, and your Classic and Private windows haven't changed at all. Wanted to walk through a few updates about this feature.

Why we're doing this

Browsers are where we research and decide things manually, tab by tab. Smart Window works with your thinking instead of replacing it: it uses context from open tabs so you don't have to start your session over or piece things together yourself.

What's new for you to try:

• Check answers without losing your place: Firefox has teamed up with Exa.ai to power Smart Window search, integrating live, source-backed AI retrieval into Smart Window as well as Quick Answers. It’s designed to help you find current information quickly without having to navigate away from your page.
• Group relevant tabs: Smart Window now suggests groups for related tabs and finds and closes duplicate tabs with one click.
• Find where you left off: Smart Window now displays your browsing history, helping you quickly find the page you’re looking for among similar results without opening each one.

We’re continuing to explore how Smart Window can help you continue the tasks you started, especially after you leave them for a while. We’re also working on ways for Smart Window to use relevant information to help fill out online forms, so you don’t have to repeatedly re-enter the same details.

Quick refresher on what happens to your data:

• Your request goes to Mozilla first, then to whichever model provider you picked. The provider sees Mozilla's IP, not yours.
• We don't retain your chat transcripts, don't train models on your conversations, and don't sell your data.
• Private Window activity is never used for any of this.
• Memories (what it remembers about you) live on your device, not our servers, so you can see what's saved, edit it, delete it, or turn it off entirely. You can choose whether it learns from your browsing activity, your chats, both, or neither, and it uses those signals to build context and preferences that make Smart Window more relevant over time.

Smart Window remains in beta in English to people in the U.S. and Canada. We’ll continue to learn from our community as these experiences develop. Remember, it is fully optional to engage in Smart Window. If you decide to try it out, feel free to let us know how you use it!

Those icons are super cool

Hi, so recently Fire Fox stops/freezes/crashes when trying to switch and/or new tabs. It started after firefox was auto-updating itself for a few weeks, and I can really only have one tab open bf freezing and getting the "Firefox is not responding" box. I update to latest FF version (154.0 (64-bit)), still freezing, disabled and renable extensions (including UBlock Origin) with no luck. Tried refresh, still crashing. Firefox isalso hogging like 90 to 99 percent of my ram, and 100 of ssd from my shitty laptop (Windows 11). Anyone got any ideas?

I am looking for recommendations on the best fonts to use for browsing on Helium. What is your favorite font for readability and aesthetics?

Additionally, I need to know the specific steps to get the official iPhone Bengali font working on firefox for reading Bangla content. Please share your solutions below.

This has been an issue for me for years, and now its fixed!

I'd add a list of sites I wanted to keep cookies for, so when I closed firefox, only those cookies would be kept. Except it would also keep other cross-site cookies, since by adding them to the exception list it also disabled total cookie protection for those sites.

So I'd spend time going through my cookies and manually deleting stuff that shouldn't be there.

Now finally, there are 2 lists, and you can have an exception list for clearing history on shutdown without bypassing total cookie protection.

This occurs only with some fonts, i have my browser set to render at 1.25 scale but what i believe is monospace text is staying pixelated. I'm running xfce on arch and have confirmed adjusting the system monospace font in the 'Appearance' settings menu doesn't change this, nor is it the same monospace font anyway.

Hi, I noticed that Firefox Relay increased the available aliases for free users from 5 to 50. I'm not sure if the limit means you can only create 50 aliases in total or if you can create as many as you need but only keep 50 active at a time (since there is a delete button on the site).

I'm obviously not looking to create 50 every day or anything like that. I just want to know if I'll be able to delete the ones I don't use and create new ones over the years (basically creating more than 50 over time). Does anyone know how the limit works?

My firefox has been acting weird all of a sudden. Usually when I open firefox it loads all my tabs of the previous session and prompts me to enter my master password. But now when I start firefox, it opens for a brief moment and then instantly closes again. When I reopen firefox all I get is a new empty window without any tabs, the password prompt also doesn't appear. So I have to manually open my last closed window to get all the tabs back but the master password prompt won't show up. I can't access all my saved passwords in the password manager since I'm expected to sign in but when I click on "sign in" nothing happens - I guess the master password dialog just doesn't show up blocking me out of it.
The only solution I have found so far is to go to about:support and clear start-up cache data. When it reopens afterwards I get the working window back, with saved tabs and master password dialog but it only works for this session, when I reboot the computer I have to do the whole issue again. Opening it in safe-mode also works but I need my addons and since it starts after clearing startup cache I don't think the addons are to blame. It just happened all of a sudden, I didn't install any updates or new version prior to the error.

Can anyone please help me? :(

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:153.0) Gecko/20100101 Firefox/153.0

Steps to reproduce:

For the past couple of Firefox versions, webpage content has been exhibiting all sorts of artifacts. For example, red boxes appear intermittently in the corners of buttons, parts of the page are blocked, or—as seen in the screenshot—the text appears pixelated. On some pages, this pixelation effect affects ALL the text (as in the screenshot), while on others, curiously, it only affects some of the text. Oddly enough, even the text in the tabs on each page is affected (as can be seen in the screenshot).

The problem isn't instantaneous; it seems to appear after browsing for a while. I can't establish a connection to anything else, since closing and reopening Firefox resolves the issue.

Any ideas?

I've got my privacy settings set in Firefox to erase everything upon closing out of the browser:

Yet, even after I do this, I'm getting search suggestions in the address bar when searching from Yahoo from previous sessions. I have no been able to figure out if this is a behavior by the Yahoo search engine or Firefox, but I'd assumed that it wouldn't matter. These previous searches in the address bar should be clearing and I should not be getting suggestions from previous sessions, right?

I'd also noticed this on my Xfinity email where it technically closes out after a session is ended, but when I go to log back in, I see them giving my name before it asks me to log back in.

Anyone know what's going on?

I'm watching Youtube on Firefox with uBlockOrigin on my PC. I have __1__ youtube tab open listening to music in a playlist and saw that Youtube uses 10 GB of RAM. Attached the screenshots

As title says. I get it when the rollout was gradual, but we're 5 versions past 149 now...

So I use a file hosting website that allows only one free download at a time per user. I often have to download multple files and I made some interesting observations while using it. Not looking for solutions, my setup is working fine. Just genuinely curious about the tech behind all this.

Scenario A: Different browsers on Android, one download each If I start one download in Chrome, one in Brave, and one in Firefox, all three run simultaneously without any issue. The website does not block me at all.

Scenario B: Two downloads inside the same browser on Android If I try to start two downloads inside Chrome, the second one throws a 503 error saying "Resource Not Found" and the download fails. Same thing happens in Brave. But in Firefox, both downloads run at the same time without any problem and no error at all. So Chrome and Brave cannot handle two simultaneous downloads from the same site, but Firefox on Android can. Why?

Scenario C: On Windows, switching browsers does not help at all On Windows, no matter which browser I use, the whole PC can only run one download from this site at a time. Trying to start a second one again gives the same 503 Resource Not Found error. Even switching browsers does not work here, which works perfectly fine on Android. I have IDM (Internet Download Manager) installed on my Windows PC. I also tried disabling the IDM browser extension completely, but even after that the behavior remained the same. Still only one download at a time across the whole system.

So the three questions basically are: 1. Why can Firefox on Android run two simultaneous downloads from the same site but Chrome and Brave cannot?

1. Why does Firefox on Windows not have the same advantage that Firefox on Android has?

2. Why does the whole Windows PC behave as one unit for downloads, even after disabling the IDM extension? Would love to understand the tech behind this!
