Hello, I’m experiencing an issue where my website https://smartstartkids.com.ua doesn’t load at all in Firefox. When I try to open it, nothing happens or I get a message like “The connection was reset” or “Network error”.

The strange thing is that it works perfectly in Chrome and Microsoft Edge on the same devices and network.

Here’s what I’ve already tried: • Cleared Firefox cache and cookies • Created a new Firefox profile using firefox.exe -P • Disabled and fully uninstalled ESET antivirus • Turned off Windows Firewall • Reset DNS and Winsock via Command Prompt (ipconfig /flushdns, netsh winsock reset) • Checked proxy settings (set to “No proxy”) • Tried with HTTP3 disabled (network.http.http3.enabled = false) • Tried from two different PCs and networks — same result • The certificate shown is from “Sectigo”, not ESET, so it seems to be correct now

Still, Firefox is the only browser where this specific site doesn’t load. I’d appreciate any ideas or help!

Thank you!

This problem only occurs in my Hotmail email account at outlook.live.com using Firefox in the last few weeks.

I typed exactly the same including spaces in both Chrome and Firefox. First 2 lines typed in Chrome, saved the draft, last 2 lines typed in Firefox but in Firefox the nonsense occurs. Amazingly the 2 lines typed using Chrome still display well in Firefox. Firefox adds the extra number in the fractions in the space I had typed! How can I get Firefox to work well at outlook.live.com?

This has only happened in the last few weeks, during all those updates. Am on 138.0.4 Are any of these updates buggy?

Recently I have had several experiences with captcha when paying for something with a credit card. I check the box saying I'm not a robot, get a green arrow, but then the purchase does not go through. Error message says I failed to satisfy the captcha, even though I was never shown the grid of images. Just now I tried the same operation with the same company invoice using Chrome, and it went through successfully by just checking the box I'm not a robot. This is very inconvenient.

I used to have an occasional sound problem with FF, usually felt when YT clips could not be heard any more. I mean to remember that it could be fixed (until next time) by restarting the file explorer somewhere in Task Manager - not a convincing solution but one I could live with.

Today, there's a new situation. Again, trigger was the missing YT sound in FF - not in fx Edge, and that the Task Manager trick didn't work (or maybe I restarted the file manager in the wrong tab?). Looking for a solution, I happened to see that the YT mute function in the FF tabs seems to be gone. However, other sounds are affected likewise. Also, I can't see them in Edge either. After various restarts (or maybe something else I did, instigated by the various instructions I found?), the sound is back.

However, while continuing to pursue possible solutions, I also happened to find that my browser is being 'administered by my organisation' - what ever that means (see two annexes). Who did that? I would say, this is not something I did, I would prefer to see it gone. But how? Will the other browsers (which I keep as a spare, and that I'm hardly familiar with) be likewise affected?

This is an equation with too many unknowns for my limited knowledge, are such effects known? Would there be an approved way-out for it?

PS I have checked https://support.mozilla.org/bm/questions/1412934 especially the message posted by lazizakhmedov1014, and do not see this to apply to me - short of a reinstall - FYI

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 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.

Hello

With the new update to Firefox v137 I am no longer able to sign in to Government sites using my bank as a sign in partner. Google Chrome will sign in so it has something to do with the new update. I have cleared cache and all data and still no luck with the sign in. Any help would be appreciated because Firefox has been my default browser for years and I'm not interested in changing.

On some sites, some Chinese characters will display as completely blank. It's only some characters, and it's only on some sites. I know one would be inclined to say the site just doesn't have correct settings, but that doesn't seem to be the case because this issue only appears on Firefox (Chrome doesn't have this issue for the same sites). (Sometimes even on the same site it will be inconsistent whether it displays... Like the Google search results will display Chinese fine, but the text typed into search bar itself will display incorrectly.) The font it displays in also appears to be inconsistent, but I don't mind that as much.

I've tried changing the default font to both Microsoft YaHei and SimSun - neither changed anything regarding my problem.

I've seen other people with similar problems be recommended to figure out what fonts are being used via inspect element, but I haven't found any example providing what exactly you're to do after you've found that information out. However, if it helps, I did that and found out the fonts being used were MS Gothic, SimSun, and Yu Gothic, though I don't know which one is causing which issue, or what I'd do about it even if I did know.

Here's an image as an example - as you can see, some characters are fine, some display in a different font than the others, and some don't display at all. I would very much appreciate advice on what to do from here.

When I'm on the Guide page, the option to change the guide to later in the day is not visible until i reduce the page to 90%.

However, when you try to advance the time, it does not work. Is shifts momentarily to the next time period, but immediately reverts back.

It works properly in Chrome.

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?

I recently downloaded Firefox and would like to use it as my primary web browser (M1 14" Macbook Pro). But my Google calendar web site is not showing any colors, making it hard to use. On my other browsers (Brave, Safari, Edge) it works fine . See screen shots below from Firefox, Safari, Brave. I have tried re-booting Firefox, the computer, reverting the Firefox theme back to basics etc., and searching on line for a solution, but I can't find anything. So far all other websites are working OK, except for 1 other that has partially the same problem. If it can't be fixed I'll stop using Firefox, which I otherwise like.

Thanks for any help.

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?

Ive been told that firefox does not support https://web.minidisc.wiki/ (Web minidic pro) and only google chrome does. I hate google chrome. how difficult would it be for firefox to support usb devices like a minidisc recorder player. I guess its down to drivers or some form of plug in? Could firefox be made to support my minidisc or is it too much of a security/software performance issue? Cheers Mark

Are you aware of the incompatibility of these two government websites that no longer are compatible with Firefox? The VA appointments of the HealtheVet site are no longer working and when I called for support they sent me to the chrome browser and says it is not compatible with Firefox. The same is now also true with the SSA website. This is a problem with Firefox or the government being forced to use chrome compatible sites only. YES, it needs to be fixed on one side or the other. Do I need to contact Congress?

I'm no longer able to play Youtube videos on Firefox. I've tried everything from re-starting laptop (this worked initially) to refreshing/updating Firefox browser as well as clearing Firefox cache and cookies. Any help will be appreciated.

Thanks, MC [email removed]@aol.com

p.s. Youtube does work and play on my Edge browser

I just installed Firefox on a new PC build and Twitch will load but just gets a spinning circle instead of playing the stream. The streams play fine on other browsers but i can't figure out why its lagging so bad/not working on Firefox. I did some digging and tried resetting cache and cookies and switched of recommended settings but nothing seems to work.

I can login into Xfinity email, but not into the billing section. I've attached three printscreen errors. The 1st is a handshake error as seen in top address bar. The second is a Access Denied error and the third is a "waiting for bat.bing.com"(a tracking cookie)error that can be seen in bottom, left hand corner.

I reached out to Xfinity tech support and was told to try a different browser. I tried DuckDuckGo and that did work and let me login and pay my bill. I told the tech that I would still rather keep on using Firefox. He said "that's something that you would need to take up with Firefox since we now know the issue is with their browser"

How do I get this issue resolved so that I can keep using Firefox as I have for many years now?

Note: Already tried clearing cookies and browsing history with no difference.
