Firefox Community Forum

When signing in to online Shaw Webmail, message says 'Security Check Failed. Clear your browser cache and retry'. Screenshot attached. Have done so in "Clear browsing and data history", (as per Firefox guidelines) multiple times, for all History and cache. Did not resolve issue. Contacted Shaw Support; they instructed to try logging in with Chrome browser. Worked fine. Issue appears to be strictly with Firefox Browser (on multiple devices). I prefer Firefox over Chrome. Any advice greatly appreciated.

Hi, It happened just days ago. The NY times does not let me read articles and tells me I am a bot not a human (I am a subscriber) or that someone is using my IP. I tried everything, clearing cache and data for everything, signed in again to no avail. I tried using a VPN to mask the IP... no success I have no problem reading it on Chrome, but I prefer Firefox. Does anyone have more ideas? The agent from NY times I contacted really was no help at all. Thanks

Although I received an answer on this question, I probably was not detailed enough to indicate why this seems to be an issue with Firefox's interface with Google, as opposed to only Google. When I'm clicking on the Google search bar I get the attached message indicating unusual traffic on the network and requiring me to do the captcha crap. What I failed to mention before is this does not happen if I use Chrome or if I go through Duck Duck Go and then into Google from there. It only happens in the top search bar on Firefox. The reason it's so frustrating is the captcha keeps going through multiple pictures, even though the captured screens are accurate for the requested pics. Perhaps someone can suggest a solution even if you still don't believe it's a Firefox issue. I'm not a computer or network expert so a more detailed explanation for how I can solve this would really help me out. Thank you.

When I try to do certain functions, filling out a form for an organization, accessing my account with Blick Art Supplies, Paying estimated taxes with the state of Michigan, none of them work on Mozilla, but if I go to Chrome, all of them work fine.

Upon opening the NY Times website, page 1 flashes briefly. Then the screen locks in on a commercial which prevents further access to the paper. I cannot escape the ad.

This does not happen with Safari or Chrome.

Help!

Is this perhaps because of the email i use for Mozilla login is different? Also Firefox is not my default browser on this windows PC, Microsoft Edge is, (although rarely used) when I do sign in with Edge the login proceeds normally. any suggestions? this is obviously not critical but I am seeking clarification.

Trying to pay my car registration renewal online with www.dmv.ca.gov but cannot checkout using Firefox. Have to use Safari. Any idea why?

Takes me to blank page.

Had to switch to Edge to get my gift card.

The Atlantic.com site says: as below, this was not the case in the past. Similarly with the NY Times I did not have this problem before I went on vacation on 10 June. Neither tech support can help. This problem does not occur if I use EDGE

Why have I been blocked?

This website is using a security service to protect itself from online attacks. The action you just performed triggered the security solution. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data.

For the NY Times site, I get the following for some but not all articlesarticles

You have been blocked from The New York Times because we suspect that you're a robot. Why am I seeing this? There are a few possibilities:

   You are browsing and clicking much faster than is typical of a human being
   Something is preventing Javascript from working on your computer
   There is a bot with the same IP address as you

I am unable to pay my bill at https://gwresources.watersmart.com/ using Firefox. After I fill out all the payment info, the website comes back with my session has expired. I then go to MS Edge to pay my bill.

Upon upgrading to v140.0 on macOS Sonoma 14.3 (23D56), YouTube no longer renders.

All add-ons (ad-blockers, development tools, accessibility tools, etc.) were removed and still the same non-rendering as of this evening June 24, 2025.

I have no ability to connect to the IRS.gov account log in page. When attempting to do so, the link reverts to a maintenance page, with the hopeful message: "We apologize but there seems to be an issue completing your request. Please try again in a few minutes." An error URL is also attached.

This is not a new problem and has been ongoing for over a year. I have found several messages in the Mozilla support system describing the exact same problem from different users. There does not seem to be a fix that has been found. The information that I have found regarding the IRS website does not suggest that it will only work with Chrome or Chrome based browsers. But I can easily use the site with Edge.

There are several sites that I am unable to access with Firefox that force me to use Edge. I understand that Firefox has its security idiosyncrasies. But As this number climbs, and to include what are public facing government sites, a question I will soon ask is why use the Fireofox browser?

Does FF offer a setting to address the following two incompatibilities?

1. In the iCarol web app, as the user is approaching the timeout limit, in Chrome the browser tab flashes a warning. This does not happen in FF.

2 In the Diaplad web app, if the user needs to record a voicemail greeting, in Chrome this ability is present. In FF this ability is not present.

I've tried to book flights repeatedly online and Firefox is preventing it. How do I nknow? because I went to Safari and the bookings went straight through. Same bookings, same sites.

I'm seeing a new trend with websites that use cloudflare like restaurant accounts, Ace Hardware, and freecycle.org. Cloudflare either rejects me upon clicking it (freecycle), or it keeps cycling with its checkbox and doesn't do anything else (Hyatt). I contacted freecycle.org and they didn't know the reason. However, I can get through cloudflare using the Chrome browser. Is this fixable, because I really want to stay with Firefox? I am up to date on my drivers, Win10, and Firefox. Thanks!

Two websites I went to using Firefox today displayed the date as 6\18\2025. Today is 6\19\2025. One of them displayed the July 2025 calendar and would not allow me to click back to June. I have two Firefox Extensions on, UBlock Original and Chameleon. Any idea what may be causing this. I'm using a MAC.
