Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

Just installed Firefox for macos Monterey.

On the "Home" tab in preferences, it lets me enter "https://www.bing.com" for the Firefox Homepage. Then for New Tab it lets me select "Firefox Homepage".

However when I open a new tab, I still get Firefox page with a Google search box.

What am I don't wrong? Thx

Just recently I am no longer able to use Bing.com to search with. Being it is my preferred source of searching for me. Google is awful for my purposes.

Could you add a option of closing tab with <kbd>Ctrl</kbd>+<kbd>w</kbd> to the advanced preference?

Also, I realized that:

```browser.tabs.warnOnClose False``` Does this option activates warn when closing the tab? If your answer is yes, it is not working at all.

Firefox detected a potential security threat and did not continue to noodlemagazine.com because this website requires a secure connection

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

For some reason, IDM will not work in Firefox/DuckDuckGo. even though it worked a couple of weeks ago. I contacted IDM support who have tried everything they have, but no change.

Here is the issue: 1. I open Firefox (Duck Duck Go is my default) (132.0.2 (64-bit) 2. I type "vintage sci fi movies" 3. Click on "videos" 4. Pick any movie (example: The Phantom Planet (black and white but this does not matter) 5. In the Choose How you Watch, I click the left icon - Watch Here, and not Watch on YouTube; also click Remember my choice 6. The movie starts but there is no IDM dialogue 7. If I then click Watch on YouTube inside the movie, it switches to YouTube and the movie starts, AND the IDM dialogue pops up.

As I said, this worked in Firefox/DDG a couple of weeks ago.

IDM version is 6.42 Build 23, full (paid for) version Oct 15 2024 The IDM Integration Module in Firefox shows as Version 6.42.22, last updated Oct 28 2024.

Can you assist please.

Hi everybody this will be a long question, and I would be really grateful for any kind of help anyone could give me, this is my case:

I use `firefox-sync` to manage all my logins information and firefox-sync's password is the unique password I save manually.

Currently I has problems with my O.S and I decided reinstall it. But also I have 2FA enable for mostly of my accounts, and firefox-sync is not the exception, and firefox-sync's 2FA is based on my gmail, so when I tried get logged on firefox-sync, firefox asks me for my verification code, but my verification code is in my gmail, and my gmail's password is in firefox-sync.

So I lost access to all my accounts, I lose my gmail, github, gitlab, stackoverflow, discord, etc etc... :'(

From the gmail side, I tried all that gmail let me try but unsuccessfully.

So, the only possibility that I see, is recover the information of the formatted partition and rebuild the previous state of Firefox. I mean:

Reading about firefox loggins, and taking a look to firefox's workdir (`$HOME/.mozilla`), I see firefox saves login's info in a json file located in `$HOME/.mozilla/$profile$/logins.json`.

So the basic idea is with a data recovery tool, try recover `.mozilla`s directory and replace it over the current environment so when I start firefox can get access to my login's info. But I'm not sure how much it is possible to recover the whole directory, and if is not posible, my question is:

What files next to `logins.json` should be my recovery targets to replace inside the `.mozilla` folder in order to reconstruct my accounts login information?

Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?
