Need help figuring out why Firefox has a memory leak after an extended use of Firefox browsing. Don't know if its the result of an extension having this issue, or if its a Firefox bug. I have also provided my troubleshooting information, and a link to my memory usage is listed below for download: https://1drv.ms/u/s!ArspaZQCMwZ-iLU_CckOfLkl9DlETQ?e=MuIqsO Thanks in advance!

daily mail website crashing right after opening..never had problems before

https://www.dailymail.co.uk/home/index.html

How do I turn off those annoying "update available" notifications/reminders that keep popping up? I've gone into Settings, and in the Updates section firefox only let's me select auto updates or check for updates. I searched online but couldn't seem to find anything about how to disable the notifications all together with the newer version of FF. It's driving me crazy, thinking of switching browsers because of this. Thanks in advance!

Dear People --- FIRST: I apologize for taking so ling. I had physical probs, that kept me from coming back. SECOND: I'm afraid that I can't solve this problem with the advice provided. There was a file mentioned [which slips my mind, and I can't look for it with out leaving this screen] that is supposed to be on my desk top. I couldn't find it, so things stopped there.

SO..... I'm reiterating my problem: I loaded an "update" to Firefox that was supposed to get around the obnoxious "THIS BROWSER IS NO LONGER SUPPORTED" message I'd get on certain web-sites [such as the Milwaukee Journal]. I never understood that, as I am careful to update programs, when the updates are available. SO: While I was on the Milwaukee Journal Site, I clicked on the "Firefox Update" that the Journal's site recommended. What happened was I got the Current Version, and LOST all of my add-ons. After problems I can't go into here, "The Cat's Back." Please advise whether I can get things back after this much time.

N.B.: I'm running Windows 10.

I use Lightfolio.com for my website hosting. My computer does not let me login or load the website using Firefox. I've deleted the cookies, and played with the settings, and it still doesn't work. I'm really needing help as this is dampering my business.

I've recently started using the Tree Style Tab extension, and I'm finding it useful, but I'd like it if the list of tabs could be automatically hidden when only one tab is open (and automatically shown when more than one tab is open).

I hoped to write an extension to do this, but opening the sidebar from an extension requires a user gesture, so I suspect I'll have to use a userchrome.js script.

From a "userchrome.js"-like environment (i.e. unsandboxed AutoConfig), I can hide and show the sidebar with `SidebarUI.hide()` and `SidebarUI.show("treestyletab_piro_sakura_ne_jp-sidebar-action")`, and I can examine the tabs open in the current window via `gBrowser.tabs`, but I can't see how to get notified when the number of tabs changes (replacing `gBrowser.tabs` with a proxy doesn't work, for example). I suppose I could just check every few seconds? That feels like a bit of a cop-out, though, and gets more and more inefficient the more windows are open.

There's an API for extensions to receive events when tabs open and close, so clearly this is possible. Where should I be looking for this functionality?

(I also don't know how I would go about unregistering an event listener (or cancelling a setInterval call!) when the window closes, assuming that's necessary to avoid leaking resources – is there an event like `chrome-document-global-created` I could listen for, but that fires during teardown of the window rather than when one is created?)

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.

My laptop lost power mid-session and since then Firefox hangs after opening and becomes unresponsive. Can’t do anything on it. Troubleshoot mode does the same. Booted up my computer in safe mode, no change.

I’m guessing a reinstall would fix it but I had a bunch of tabs open that I’m really trying not to lose. And I didn’t have an account to save them, I’ll rectify that after this.

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

Until yesterday everything was fine. I was able to complete recaptcha. But when I tried searching something today, I couldn't do it because of the recaptcha. It was stuck on infinite loading. Every website I visited the problem was there. I tried fixing it from the tips I found in the forum here but nothing seems to work. I was frustrated. Then I tried Brave browser and it was working. Please help me fix this problem. Thank you.

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

Firefox 125.0.2 on Mac

When I press shift+cmd+D to bookmark all open tabs, instead of the links being saved to the designated folder, they are all saved to "Bookmarks Menu". The designated folder itself also appears with these links but it itself is empty.

I would expect shift+cmd+D to bookmark all links in the folder and the folder to appear in "Bookmarks Menu". This is what use to happen ages ago. I'm not sure what caused the change in behavior. Anyone have any ideas on fixing this?

I have accidentally end up with two FireFox accounts. I want to combine them, but I can't change either account to the other one because FireFox tells me that the replacement email/account is already in use. How do I get around this?

your time and help is appreciated.

Everytime i try to watch a video it says it can't play or it just sits there buffering. Youtube works but only lower quality, but every other site i go on doesn't. Twitch won't load, other sites show Error Code: 102630. This is only a problem on my browser on my windows pc I have. On mobile the browser works great and has no problem showing videos so it a problem for my pc browser.. I've tried all of the steps, i've updated, i checked drm and even went into config to check there. But nothing works, it still can't load videos. I have version 125.0.3 and for me it's the latest one. I even turned off all of my add-ons to check if it works or not but nothing there either. It worked before, just now the latest two months it hasn't. What can I do in order for the videos to load? Thank you for your time.

I have Ubuntu 22.04 (on a Dell Optiplex 3000) with a minimal installation. I downloaded Firefox 125, removed the SNAP Firefox and installed this Firefox with no issue. I can run "firefox --kiosk" and Firefox runs in kiosk mode with no issue.

I have made some changes in the "about:config" part of Firefox. I have also made some changes to the Ubuntu keyboard shortcut list. There is only one user created on this system and I have configured Ubuntu to login this user automatically upon reboot.

However, if I setup Firefox --kiosk to start automatically (I use the gnome-session-properties application to achieve this) and then reboot, Firefox does run, but it does not appear on the screen. If I enter the "switch windows" keyboard shortcut (ALT-TAB), the Firefox kiosk appears.

So, is this something I can fix by changing the Firefox configuration, or is it an Ubuntu configuration change. If so, can anyone tell me what I should do, or have an idea how to debug this?

I've had this issue ever since switching to a new laptop. This issue is specifically within Firefox (I have tested this in other browsers and programs, and the issue isn't there. Everything else works perfectly fine!)

Essentially, whenever Firefox plays multiple sounds at the same time (for example, I use both youtube and discord in-browser) the second sound will briefly mute the other sound. (Going back to the discord-youtube example, if I am watching a youtube video and recieve a discord notification, the youtube video will pause for about half a second.) Or if a site has background audio but also plays a short audio clip when certain elements are clicked, for example, it will cause this "overlapping" issue. Again, this issue is only within Firefox.

I am using Windows 11 if that helps. I've already tried using a Firefox Refresh and peeking in about:config but I'm totally lost as to what I can try next, since I can't find any other examples of people with this issue online. Sometimes the issue briefly fixes itself but then reappears.

Starting yesterday firefox, no recent updates etc, gives a 403 error for several large corporate sites and 404 page not found for most paypal payment pages. These sites/pages work fine with Chrome. There were no changes by by myself to my firefox installation, not any antivirus changes.

Within the last hour today everything is working properly. What is going on? jn
