Firefox Community Forum

Hi!

Yesterday, April 5, 2025, my Firefox started displaying this message for every search typed in the browser:

"Our systems have detected unusual traffic on your computer network. This page verifies that it is really you, and not a robot, sending the requests. Why did this happen?"

I tried a few solutions: I cleared the cache, restored Firefox, reinstalled Firefox, restarted the internet modem, reset the computer's DNS using the ipconfig/flushdns command, scanned for malware with Windows Defender, and scanned for viruses and malware with Kaspersky, but the problem persists, both in the normal tab and in the private tab.

I contacted my internet provider, and they said there is no problem on their side.

In Firefox, I always use the default search engine "Google".

When I change the search engine to "Bing", the problem does not occur.

The problem does not occur in the Google Chrome browser, only in Firefox.

I am using Firefox 115.22.0esr (64-bit), Windows 7 operating system and internet connection via network cable. I only have one computer connected and I don't use VPN.

Please, can you help me?

Thank you!

When trying to access the Tax Withholding Estimate at IRS: https://apps.irs.gov/app/tax-withholding-estimator it will not work in Firefox. I get this message: "Application error: a client-side exception has occurred (see the browser console for more information)." I don't understand how to interpret the console messages.

I get the message after filling out the "Information about you" page and clicking NEXT. Website works without issue in Google Chrome.

Is there a setting I have clicked in Firefox that is breaking the website or is the website to blame?

Using Firefox 128.6.0esr with no extensions installed.

I understand Firefox has always had a bit of an issue with SVG - and the 'Firefox has higher standards' doesn't really cut it.

I personally love Firefox but the number of users doesn't warrant spending much time redevloping sites to overcome a shortcoming that no other browser has.

Eg of a website the problem applies to - https://fontmellmagnavillagehall.co.uk/

Hello After last firefox update this page mail.proton.me (specifically: https://mail.proton.me/u/0/inbox) does not load for me.

It works in chrome and edge but not firefox. I cleared my cookies and cache but it did not help. All I get is blank white page and sometimes error message. I attach screen from my F12 menu when I try to load page. In brave for example there is much more activity than in FF.

Hello,

I can no longer log into twitch, it says my browser isn't supported.

Before you say anything: I have the latest version of Firefox, I have disabled all addons, cleared all cache and cookies, even tried a complete, clean re-install. I can log-in in other browsers, just not in Firefox. I have disabled enhanced tracking protection as well, didn't work.

Does anyone have an idea?

Chrome seamlessly harmonizes with the PowerToys FancyZones feature in Windows 11. In Chrome, I can drag a tab out of a browser window, and instantly snap it into a FancyZone. I can also quickly arrange multiple separate Chrome windows into FancyZones without issue.

Firefox's interaction with FancyZones is not good. When I drag a tab out of a window, it doesn't allow me to snap it into a FancyZone. I first need to release left click, allowing the tab's new window to appear, then I can snap that window into a FancyZone.

The biggest occurs when I have multiple Firefox windows open and snap one of them into a FancyZone. Often, one of the open Firefox windows will spontaneously shrink itself in size. When I try to manually resize the window back to normal, it shrinks further and further, until it is an invisible sliver. The only solution when this occurs is to fully restart Firefox.

It seems strange that Firefox has such poor compatibility with FancyZones, which is growing in popularity along with other productivity tools in PowerToys. Wondering if anyone else has experienced these issues, if there is any workaround, or if there is a fix being worked on.

Neither Spectrum nor Frontier will allow me to login using Firefox browser. No problem at either site if I use MS Edge browser. I've tried all of the suggestions from Mozilla on line (ex: clear recent history, check add ons, etc) and nothing has corrected the problem. Does anyone have a solution?

I used the CSS animation property called animation-timeline , which is written as:

element{ animation-time: view(); }

When I view the webpage on Chrome, Edge, Opera, and even on Phoenix browser, the animation works.

It is only on Firefox that the animation does not work. I even added the Vendor-prefix of " -moz-animation-timeline " to the CSS property, and it still didn't work on Firefox, while it is working on all other browsers.

The CAN I USE website ( https://caniuse.com/?search=animation-timeline ) tells me that Firefox does not support it at all.

It however said that I can enable it, by setting "layout.css.scroll-driven-animations.enabled" to true.

1.) I don't know what that means.

2.) Would my website's users be able to see the animation on their Firefox browser, if we assume that I make this setting ?

3.) I am using Firefox version 138.0.3 (64-bit) : What can I do to see that both I and users of my website are able to see this animation on Firefox ?

Why am I getting this message and how can I resolve the problem without switching to chrome?

I am trying to sign-in to a site we use and when you hot sign-in the page goes blank white??

The site works on Microsoft Edge so I know its noit the site.

Please advise.

I am encountering an increasing number of sites that don't work with Firefox but do work with Chrome. I have tried turning off add-ins without success. Is there a way I can easily reset Firefox to its initial state and then return it back.

dunno if this is the right board, but here goes...

I discovered a bug with Firefox and the pen/touchscreen on my lenovo X1 tablet.

Using the touchscreen, move the map, map works as it should. Can pinch to zoom, ect.

Switch to the pen, map works with pen.

Touch the screen again and Google maps doesn't respond to touchscreen anymore, only the pen, and refresh does not fix it. I have to close and re-open maps in a new tab.

In chrome, this does not happen. Only in Firefox.

I can no longer open my gmail in firefox. I need to open chrome to load my gmail and I never use chrome. So why can't I load gmail into my firefox account. Everything else is loaded except my gmail.

Just recently I have found that certain sites are unavailable to me using Firefox but I can access them using Edge or Chrome. One particular one is Squarespace.

Is there anything known - how should I tackle this?

I'm trying to access Tiermaker but it won't let me because it says it is insecure. On other browsers, however, I can access it fine without any warnings. I don't have any accounts on there or anything that could be at risk. How do I access Tiermaker?

When I log into my Outlook Web account, after putting in username and password, it sends me a verification number to my phone. When I put that number it the screen says "Logging out of Microsoft Outlook" and then takes me to the logged out screen. This was working fine until the last update of Firefox, and it works fine in the Duck Duck Go browser. It also works on my Android Cell phone.
