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.

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

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.

The errors I get are kind of all over the place though. I've completely deleted and reinstalled Firefox, and removed all extensions too.

It will loop to the login screen over and over, or I get the message 'An error has happened, try again later'...

I used the browser console and didn't get anything that seemed usable. I use Strava nearly every day so I'm having to use Safari. And this issue is on all of the mac and Windows systems I use. 'Troubleshooting Mode' didn't work either.

Help!

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.

Regards

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.

Two financial websites I normally look at with firefox suddenly have no images anymore. I think it's the last Firefox update that caused it. Both websites look okay with Chrome.

Using Firefox, when I enter Puritan.com in the search bar the browser takes me directly to Nestle.com (a foreign website). This does not occur when using the Chrome or Edge browsers.

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!

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.

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'm get an Access Denied for a web-site I have frequently accessed. Only Firefox on my laptop has this issue. Edge and Chrome are able to access the web site. Firefox gives me the following error:

You don't have permission to access "http://www.nfm.com/" on this server.

=========================================

I have cleared my cache and data and cookies and nothing works. Able to access it from my phone's firefox browser.

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.

Whenever I get on YouTube the website will not completely load, If I restart Firefox and access the website it then loads completely. However when I click on any video it does the same thing as the included picture, however I can play the video, but I cannot click on anything. This only happens on Firefox, any other browser and I have no issue. I have also disabled my plugins and it does the same thing. I have tried multiple different suggestions from your help page and other solutions on the internet. If I could have some insight would be extremely welcomed, thank you and have a wonderful week.

When using website at https://tools.myfooddata.com/nutrition-facts/170112/100g/1 , the search box titled "Search for A Food" shows up in Google Chrome, but not in Firefox. In Google Chrome, it can be seen in the upper left part of the web page, but I can't find it in Firefox. Also, when I click on the button called "Instructions" on the web page, nothing happens in Firefox, but when I click on that button in Chrome, it opens up an instructions menu. What can I do about these things?
