Firefox Community Forum

A couple of days ago, my work laptop popped up a message that said: (from firefox) couldn't load XPCOM (OK)

Today, same work computer, another message popped up from firefox: Entry point not found. The procedure entry point ?WindowsOleAut32initialization@mozilla@@YA_NXZ could not be located in the dynamic link library C:\Users\Berlye\AppData\Local\Mozilla Firefox\xul.d

I have absolutely no idea what this means except that FireFox will not open. I am a very senior citizen and totally electronically challenged, so I need help in a-b-c fashion as to what this means and why I can't open Firefox on my work laptop.

Thank you.

I have had Windows 11 added to my computer. I do not like the ookmark tool bar. Is it possible to have my bookmarks listed vertically on the left side of my screen like I had previously in Windows 10?

Hello, I am running Firefox on a W10-Pro PC. I always click the lock to check certificate validation. In the last month I keep seeing "Connection verified by a certificate issuer that is not recognized by Mozilla".

When I click for more information I see that "Norton Web/Mail Shield" does not recognize the certificate issuer. When I click on Learn More it takes me to a Firefox site "How to disable the Enterprise Roots preference" I also checked W10 certmgr.msc and I see Norton is listed. Images included below. I would love to resolve this issue. Thank you for your time.

Firefox abruptly stopped working on my MacBook Air. When logged in as the admin, Firefox works fine. When a 2nd user logs into an account on the Mac, and tries to open Firefox, Firefox asks to install a helper tool. If I do so (with the admin credentials), the helper tool prompt goes away, but then if I click to open Firefox the icon just bounces and I get an "application not responding" warning.

I have tried refreshing Firefox from the admin account. I deleted Firefox and deleted all user profiles, re-installed Firefox, and still the same thing happens (works fine on admin account, does not work for any other user on the Mac). I am also unable to open Firefox in troubleshoot mode (option key). Even with the option key the Firefox icon bounces on the dock and never opens.

I can't share any data because I can't open the app.

Any help would be appreciated.

Thanks.

Hi, I just installed Windows 11, version 24H2 and now in Firefox I'm continually prompted with "Awaiting Location Permission, Grant Firefox location permission in system settings".

The problem that location has been turned off by admin on this computer. How can I stop these continual prompts from Firefox? I have checked the box in Settings to block location requests from new websites but am still getting the prompts.

Thank you.

Recently I started using Bit Defender. I have been getting these security messages: Suspicious connection blocked now

Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an expired certificate to updates.tb.ask.com. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk

I have just installed "Opera" browser which I thought would allow me to install an App called "Marine Traffic" onto my computer. It seemed to make changes to my default browser which is Firefox, so I re-installed Firefox. Now when I click on Firefox it comes up with a search bar but it is not the usual search bar but a largely blank screen with just a search bar in the middle. It does come up with an option at the top for another search session and when I click on that it is the normal Firefox browser screen. Can I get rid of this first strange blank screen with search bar? Mark

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

The thumbnails can be momentarily seen but within less than a second they disappear. Not happening in edge so doesn't seem to be a computer setting. Cleared all cookies and cache in firefox. No different. The attached image shows the pictures that are missing in firefox. Image taken from an Edge search.

Thank you in anticipation. Steve Balderson

Hello,

after update of window 11 to 24H2, Firefox keeps crashing on start. I completed deinstalled Firefox, rebooted and installed again, no effect. I switched off hardware acceleration and all add-ins and selected system theme, no effect. No crash occurs when started in troubleshoot mode. I did a clean-up (in troubleshoot mode), no effect. What should I do now? Where is the error log?

Regards Christian

I'm trying to measure power consumption in Firefox using automation. My goal is to get power consumption metrics for specific webpage loads.

What I've tried: 1. Using Puppeteer with Firefox's profiler:

  - Enabled power profiling preferences
  - Used the Profiler CDP commands
  - Got profile data but no power metrics

I know Firefox DevTools has power profiling capabilities in the Performance panel, but I need to access this programmatically. Is there a way to: 1. Access the same power metrics that Firefox's Performance panel shows? 2. Get power consumption data through Firefox's debugging protocol or any other API? 3. Enable and collect power profiling data in an automated way?

Any guidance on the correct approach would be greatly appreciated!

When playing videos in Facebook after a few of them I get a blue circle spinning . When I use chrome I don't have a problem.I have had Firefox for over 10 years ,if I cannot fix this Em going to have to use chrome

A few months ago after an update to Firefox the window would open but be transparent with no controls visible. I tried the refresh Firefox option which worked but left other problems. A website has a medium blue header at the top with white fonts (links) on it, which still appear that way in Chrome and Opera, but since the refresh the header is black with black fonts in Firefox (which of course you can't see). There are also variations of this problem on some other other websites. The only way I can see links on those sites is to set color management to override 'always'. Is there any way to fix this problem? Thanks Mike

I've used Norton Safe Search on FireFox for years with no problem. But few weeks back, when I use Safe Search, it does no longer brings back the green checks indicating the site is safe. It works with Edge, but not with FireFox. I've contacted Norton and still waiting to get a response. Anyone have idea as to what is going on and how to fix it?

thanks -
