Firefox Community Forum

I have been using this wonderful browser since 2012, and it has been my default browser ever since. Recently, I've been facing an issue where I can't upload images, audio files, videos, or any other attachments on WhatsApp Web through this browser. To verify the problem, I tested WhatsApp on a different browser, and everything worked perfectly there.

I would appreciate your advice on how to resolve this issue. Please guide me on what steps I can take to fix the browser and restore normal functionality.

In Firefox, a lot of my pages are not loading at all...the tab just shows that the website page is loading but it never does. The menus of the website will appear, but pages are not loading. This is not happening in MS Edge. I prefer Firefox, but lately have had to go to MS Edge to load pages. What could be happening?

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.

Hi,

I’m facing an issue with my website’s fine checking tool on Mozilla Firefox. My website is evgfinescheck.com , and the tool works fine in some browsers, but on Firefox it doesn’t load properly and sometimes shows an error.

I am already using the latest (updated) version of Firefox, so the issue is not due to an outdated browser. The tool either fails to fetch data or doesn’t respond as expected when users try to check fines.

I’ve checked basic things like internet connection and browser updates, but the problem still persists specifically on Firefox.

Can anyone guide me on:

What could be causing this compatibility issue? Are there any common JavaScript, API, or CORS-related problems specific to Firefox? How can I debug or fix this issue?

Any help would be appreciated. Thanks!

Facebook page fails to fully load often (not always) and in some occasions it load partially -instead of a picture it shows a blank box with a description of what it is supposed to be on the box.

Using other browser (Edge for example) loads the page fine in the affected Laptop and loading on an IPad using Firefox works fine too.

I have "flushed" the WI-Fi and "requested" a new IP for this computer and it is hard to tell if this solves the problem temporary or it is just the on-off nature of the problem.

In other occasions the page appears to load ok but the pull down menu (like notifications) are "blank" or it just appears to be loading and never navigate to the requested page.

In the sample below (image) is similar to the issue although in this case the page loaded after a few seconds. Note the missing information.

Hi Everyone,

I've been having this problem for a wee while when I'm browsing facebook (which works better in Chrome) the site on firefox and as well as messenger is really laggy and I'm wondering if there is a hidden setting that I should change to improve this?

I only have adblock addon installed and I cleaned out the history and browser cookies ect but the problem still remains.

Any ideas? Thanks Rob

After the most recent FF update, I can no longer upload pictures from my laptop to FB. I cannot see replies to posts in the main feeds. I have to go to the individual post pages to see them. Upon trying to sign into FB I often now get a message that says the feature is not working, but I click on it again and am able to log in. The feeds are taking a long time to load - I can see 3-4 posts and then icons that show the rest of the feed is trying to load, I do not have AVG or the other thing (bitdefender maybe, or something like that) others have been having problems with, that was resolved in a recent 'FB not working' thread -- that was supposedly solved with a recent update. A few minutes ago my laptop shut down while I was on FB. I did all of the suggestions regarding clearing the cache, cookies, etc. when I first noticed the problem so there is still a big problem with FB. I did report my inability to upload pictures directly to FB but I don't have any replies from them. Unrelated, I am sure, but my bookmarks were gone again this morning, for like the 24th time and I had to do the profile folder fix to get them back. I did not cache or other cleaning before I shut my computer down last night. It last happened a few days ago, unrelated to the cache etc cleaning after I noticed the FB problem. I have Norton antivirus and FF is synced to my cell phone but I prefer using my laptop for all internet activity because the screen is obviously bigger. I do not want to use another browser because of security issues. Thank you.

When I do a search on firefox I keep getting the following error and have to go through the CAPTCHA BS.

Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot.

This just recently started happening. I'm getting very tired of having to pick out crosswalks, or motorcycles of buses.

This doesn't happen when using Chrome. May have to ditch firefox!

I play https://crazyshooters.com/ and https://crazyshooters2.com/ a lot! But the game became laggy since Firefox 148 and my ping spikes up. Other browsers play fine. I am on Linux Mint if that helps. (147 and below run fine)

Hi everyone, my website YouTube Thumbnail Downloader

is not loading properly on Firefox, while it seems to work on other browsers. Sometimes the page loads partially or shows styling issues. Has anyone faced a similar problem, and what could be causing it? Any help or troubleshooting suggestions would be appreciated.

Hi,

I'm seeing a strange issue in Firefox when using an online work-hours calculator for payroll calculations.

On this page: https://mauricettecalcul.fr/

When I enter certain hour and minute values and convert them to decimal hours, Firefox occasionally returns a slightly different rounded result compared to Chrome on the same machine. Because these figures are used for payroll, even small rounding differences can be problematic.

I've already tried clearing the cache and testing with extensions disabled, but the behavior remains.

Has anyone experienced browser-specific rounding or calculation differences in Firefox with JavaScript-based calculators? Is there a way to identify whether this is a Firefox issue or something related to how the site handles numeric calculations?

Thanks for any suggestions.

For a while firefox has been having issues where on youtube in particular when tabs are closed they will continue to play audio for a bit after they are closed. More recently I have closed tabs and the audio keeps on going indefinitely after the tab has been closed. This is on the latest firefox (151.0.4 64 bit) on windows 11.

This only seems to happen with youtube and in general youtube playback is buggy, slow, and lags the whole browser taking several seconds to switch tabs to or from a youtube tab or even close it.

I want to be able to make voice and video calls via facebook messenger using my PC camera and microphone but, the message I get is that "voice and video are not supported on this browser (Firefox/Mozilla) . It is supported on other browsers. I really don't want to switch browsers, I love firefox. I did find a couple possible fixes via advanced WebRTC settings but everything seems fine, i.e. it is clicked on true not false. I need this soon, can we get settings changed?

I am on iMac Tahoe 26.5.1. I cannot use Netflix, or HBO Max. Both say that my brower is out of date. My sofware indicates that my Firefox is the *latest version available. Please advise.

Hi, I have tried all the changes to settings etc but still cannot load certain web pages, i just get a white screen, The pages I cannot load are things like: Facebook Discord Amazon Seller Central Payment screens

This is just a couple I can remember, I have tried other platforms like edge and these sites work fine. Please advise as I would rather use Firefox Thanks Tony

I've recently switched to Firefox but am finding some of the performance a bit cumbersome. I am continually being asked to hit "Send" ["To display this page, Firefox must send information ..."] when I am logging into my Outlook email or looking at my bank information. I'd rather not be "resending" these pages each time and am wondering if there is a setting.

Recently, I've been having a problem with signing in to things via my Google account – the problem being that I can't.

Whenever I click on the "sign in with Google", it redirects me to the "accounts.google.com" page, prompting me to choose my account, but once I do, I get redirected to "accounts.google.com/gsi/transform", which is just a blank page with nothing in it (see image attached).

I know this is not a problem with Google, as I have no problem signing in anywhere else.

This happened to me once before, but the reason was one of my extensions, which for some reason interfered with the sign in; however, this time this solution does not work. I tried disabling every single one of my extensions, turning all kinds of protections in the settings on and off, deleting all cache for all relevant sites, but to no avail.

I of course also tried looking this problem up on the internet, but whenever I found someone with this problem, the solution that worked for them was always just disabling an extension.

Thank you for any answer.
