Firefox Support Forum

when I search for a page after opening a tab. The page will load slowly then stop. I'll then have to hit enter again for the page the load. This does not happen with Chrome or Edge. Any ideas how to fix this frustrating issue. Thanks.

Hi, I've been trying to get the Multi-Account Containers Add On to work on my computer for quite some time. Would be very handy for me. When I add the Add On to my browser the icon on the top right of the screen just won't show up. Don't know what I've been doing wrong...? How can I access the container settings someway else? I've made changes to my FF settings in regards to privacy via the recommendation from Sun Knudsen but don't really see an issue here. Thanks in advance!

macOS 10.15.7, Firefox 125.0.3

I was unable to sign in Qobuz from yesterday. I have been using Firefox ver 115 to play streaming music from Qobuz on my Windows 8.1 PC as its sound quality is better than other browsers. Yesterday, I found nothing happened after clicked the SIGN IN button on Qobuz's login page, however I had no problem using Google Chorme to login.

So I uninstalled/re-installed Firefox, and tried different older/newer versions, still didn't work.

I tried another PC running Windows 10, with Firefox ver 124.0.2, got the problem.

Please fix the problem ASAP, Firefox team. Thanks.

Its purer sound is the main reason I use firefox, instead of other browsers.

When I turn off the windows animations in Windows 10 the font on Twitter.com changes somewhat. I believe it is altering the character spacing/scaling.

I have not had this behavior on other browsers (Brave, Edge, Chrome & OperaGX tested). I have not noticed this on other websites, but I also haven't really looked.

Windows version 22H2 (OS Build 19045.4291) Firefox version 124.0.2

Images provided are with them off, then on

Steps to recreate 1. Load a tweet (tweet in the images: https://twitter.com/FedeItaliano76/status/1779855670432408011) 2. Turn off window animations (settings->display->show animations in windows->Off) 3. Reload the Tweet

This is not a critical issue for me, but I think it's worth mentioning

What strategies or technologies has the Firefox platform implemented to ensure efficient memory management and minimize resource consumption, particularly in handling large-scale web applications and multimedia content?

I choose a new theme. After a while, I close Firefox. When I start Firefox again, my chosen theme appears briefly, then the default theme replaces it. Why? FYI: it doesn't happen with just one theme.

I am using the latest version of firefox nightly. I notice this on another PC that shares the same profile. However one of my PCs doesn't take this long and it uses the same profile as well. It also seems that the pinned tabs are not loading correctly because I get errors with those pages too.

Since the 2 APR 2024 FF update, Washington Post articles are not displaying fully. When opened, the article flashes the full version, then only displays the top photo and the first two paragraphs. When opened in EDGE, all articles open fully as expected. This issue is only occurring in FF.

Actions taken: Cleared cache, same result.

Please advise.

Receiving this error: Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

My desktop app redirects user to a login screen on Firefox, and I want to automate it using Selenium. My current workflow: 1. Launch Selenium-controlled Firefox browser using GeckoDriver 2. Click on "Login" button on my desktop app. The desktop app launches the login screen on user's OS default browser using the default user profile (in which case I set in profiles.ini to the temp profile copy created by Selenium). 3. (ERROR) Popup on the above error is displayed

Code: import configparser import os

web_driver = selenium_webdriver.Firefox(executable_path='C:\\Users\\mnxl\\.wdm\\drivers\\geckodriver\\win64\\v0.34.0\\geckodriver') profile = web_driver.capabilities['moz:profile']

1. Path to the Firefox profiles folder

profiles_path = os.path.expanduser(r'~\AppData\Roaming\Mozilla\Firefox')

1. Path to the profiles.ini file

profiles_ini_path = os.path.join(profiles_path, 'profiles.ini')

1. Read the profiles.ini file

config = configparser.ConfigParser() config.read(profiles_ini_path)

1. Find the section for the profile to set as default

for section in config.sections():

   if config.has_option(section, 'Path') and config.get(section, 'Path') == profile:
       # Set this profile as the default
       config.set(section, 'Default', '1')
   else:
       # Set all other profiles as not default
       config.set(section, 'Default', '0')

1. Write the changes back to the profiles.ini file

with open(profiles_ini_path, 'w') as configfile:

   config.write(configfile)

Please someone help me with this. My primary email has been breeched and because I was honest with the service --instead of just saying I need help resetting my password. Thay are asking me to send them a copy of my drivers' license and a photo "selfie" of myself to recover my account.

This is where I draw the line -- all invasions of privacy we have learned to live with but not this -- I could give them the transaction ID from my last Payment from Paypal period -- but that was not good enough. If I was being deceitfull I could easily provide the crdentials they ask for and it could all be fake; so I told them to get lost as I was paying for the Premium service anyway. I can contintue to use that as my ID but sonner or later someone is going to want to send me a code there and I can't retrieve it. Tonight they did not ask so I was able to get in here.

Everybody has a place to change your password but few have a place to change your sign-in ID. If I can get back into Firefox with a new ID and set 2 step validation I shouls be okay as faras the average user gors. The other option that I know of is to stary a new Firefox account. I alread have a lot of people and business's that I have to get my new email to.

Thanks To Anyone with any ideas.

Sincerely Paul

Starting today (Apr 30), when trying to open firefox the following message appears:

"Firefox is running, but not responding. The old Firefox process must be closed to open a new window." My options are to close firefox or cancel.

When selecting close firefox, the message will reappear with the same options. I am unable to run.

Steps I have taken: Uninstall Firefox Download latest Install

Message still appears

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?)

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

Dear all, I would like to know how to disable the automatic insertion of the tag
in a text editor in Firefox. I am using Froala, and I am experiencing this only in firefox. Chrome and Edge do not add this tag automatically. Thank you for you support. Kind regards, Cristiano

Hi everyone,

I'm running Firefox which I compiled with vaapi support because I was trying to use hardware acceleration for videos, so I think this bug may have something to do with that. Every time I open a pdf file my browser instantly crashes. When I use troubleshoot mode I have no such issue. I then tried with a fresh all-default user profile with no add-ons, nothing, and still I crash when loading a PDF. Any pointers would be appreciated.
