Firefox Community Forum

I have a new macbook air running Sequoia 15.3.2, firefox is up to date, my battery which should technically last about 12 hours and I only get 5. Ran through everything with Apple and they said it is a Firefox issues. I don't have any extensions, add on etc. Thoughts?

Attachment is a screenshot shows task manger shows there are 64 open files open, when I have only 4 windows open. What would causing this?

Over night Firefox closes and close all my open windows. I need the windows remain open.

Thank you for sharing your wisdom with me.

Since recently 1~2 version, my Firefox keeps consume large amount of memory and release it repeatedly

Even I restart Firefox and do nothing, it will start doing this again

I use about:processes and about:memory to capture this seems the main process's "tab.query" causing this, please check

PS: sometime it will consume till system max (64GB) and cause my OS out of memory. PS2: that wave-like memory usage is cause by Firefox

I asked this a year ago and never saw a solution (other than 'gee, it should work yet'.) I use the local Windows Hosts file to give my router a quick reference name to get into it. That too has worked for years but began to fail last year. Inconvenient. The best I could track this down, it has something to do with forced DNS lookups and skipping the old Hosts file. If so, any work around to get my system simplicity back? Attached is what I see on each attempt.

I tried various settings for DOH and nothing works. I can reference the Hosts file in a Windows Cmd Prompt and it resolves just fine. Something is screwy in Firefox for some time now and I'd like to know what.

I'm using Firefox 130.00 on a MacBook Pro (15-inch, mid-2012) running Catalina (10.15.7). It has run flawlessly for years, but suddenly won't open, and only hangs, requiring me to Force Quit. It stopped working on Thursday, 9/12, which, I notice, was the day it was last modified with an automatic upgrade. I have quit and tried restarting multiple times, but am unable to get into it at all and, therefore, cannot access Troubleshooting Mode. I have NOT yet tried deleting it and downloading a fresh copy. I would like, if possible, to retain my open tabs, Bookmarks, and History.

Please advise—and many thanks!

I've loved Firefox for years but can no longer use it because I have been unable to resolve this issue. All was well, an update was done, and bingo, I got this message. I don't know how to fix it. I removed Firefox from my desktop and re-installed. Same problem.

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem."

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.

I get the server not found error on almost anything.

Hmm. We’re having trouble finding that site. We can’t connect to the server at [literally almost any site] If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

The site usually loads after I wait like 2-3 mins before reloading the site, or I force reload it around 7 times, but I cannot find a way to make the issue go away. I have refreshed Firefox, I have uninstalled and reinstalled it fresh, I have opened Firefox in Troubleshooting mode and the issue persists. I am at the end of my wits. Someone please give me something else to try.

i host diablo_web_simple on my root running nginx when i use chrome it only loads the chunks of diabdat.mpq once -> then loads them from cache when using firefox it always loads the chunks and doesnt use cache -> this results in slower load and less performance

diabdat.mpq = ~270mb chunksize = between 1-7mb combined chunksize of loading game: ~65mb

i already set in about:config browser.cache.check_doc_frequency 2

i also set headers for caching this file in nginx

nothing works pls help

Cannot play sounds (videos) on Firefox. Can on other browsers. Went through suggested solutions, nothing worked. Firefox recently sent out an update. I downloaded it, didn't change anything.

In the last few days, the common Cloudflare widget required to login to many web sites has abruptly stopped functioning in my browser. I'm trying to diagnose what's caused it. I'd appreciate any suggestions or advice.

I noticed the issue on nexusmods.com, but I've confirmed it's a universal problem on ANY site that uses Cloudflare protection. I've continued to use Nexus as my test case.

Observed behavior: 1) The Cloudflare widget loads 2) It displays a checkbox noted, "verify you are human." 3) I click the checkbox. 4) It immediately begins "thinking" (spinny circle and "verifying...") for about nine seconds. There is an "error" message that appears during this, but no details are offered (see screenshot) 5) The widget reloads. 6) Go to step 2

This is an infinite loop.

Fixes attempted: - Disabling all extensions (uBlock, NoScript, Privacy Badger, Decentraleyes) - Clearing cache - Updating to the most recent FF build - Accessing in a private window - Changing DNS settings from Cloudflare to NextDNS - Disabling DNS over HTTPS altogether - Disabling HTTPS-only mode

I cannot use Firefox or Thunderbird I keep getting an error code: PR_CONNECT_RESET_ERROR The problem started straight after the latest update a few days ago.

I have cleared the cache and cookies I turned off the addons and extensions I shut down the internet security I changed the proxy settings to "no proxy" I even changed cert9 to ccert9 and had firefox generate a new cert9

Nothing has worked.

HELP!

Popup GUI elements if pulled up twice in quick succession spike my CPU usage and crash the program

some examples: -menu bar menus -the menu button -context menus (websites with their own context menus do not do this) -preview tooltips

I've tried disabling extensions, turning hardware acceleration off and on and disabling AI to no avail. Disabling the preview tooltips 'worked' but I'd prefer not to disable everything here. Are there any other settings that might help?

Why does hitting my Home button open another tab? It's irritating and unnecessary. How do I make it stop?

For that matter, Why can't I open a new tab with my home page already open? I want Duckduckgo. You are bullying me into a blank page or a Firefox page. I used to have a choice.

Firefox start crashing after the recent update, I use trial and error and figured it's specifically Youtube. Browsing on other sites, even watching videos from other sites has cause zero issues so far. All my recent crashes all states: "EXCEPTION_BREAKPOINT"

my last three recent reports: https://crash-stats.mozilla.org/report/index/4728ddd7-dac7-40a0-89d0-823fa0241008 https://crash-stats.mozilla.org/report/index/6b646b7c-bc88-44a9-9d57-4b6360241008 https://crash-stats.mozilla.org/report/index/2db09a8d-e049-4753-a9dd-9a4750241007

when doing image search (not by words ) in Yandex or Google the CPU clock is at full throttle (4.51ghz) And the pc starts to heat and slow down. on any other usage the pc is great . 8cores 16threads NVME 3X4 32gb ram gtx 3060 There is no issue on : ungoogled chromium_129.0.6668.100-1.1_windows_x64

I am trying to move one tab from one window to another. It says I should be able to move it just by clicking on the tab and dragging it to the window I want to move it to. But, when I try this nothing happens, it won't move.

Want can I do to resolve this?

Thanks
