Since latest upgrade (1/16/2026) I cannot log in to Outlook email. This is specific to Firefox 147.0.1 (Chrome and Pop Peeper logins to Outlook work fine). I tried clearing cache, updating, restarting, rebooting, trouble-shooting mode, private window etc. to no avail. I get 400 error from Outlook.

I'm having issues using Firefox with the Facebook site. Groups are slow to load and sometimes the chat and notification windows take forever to load with shimmering panels or a wait cursor displayed. I've cleared the cache and deleted the cookie, but that didn't rectify the issue. I don't have a problem with Edge.

okay this just is bad as of today and last Firefox update and with all extensions off . this is what i got when i tried to post and watch a video. it happens on all the videos on Facebook i have tried contacting them as well and that is an almost impossibility it is only in Firefox they work in chrome and edge i even tried reinstalling Firefox ans still get bland black screen I have tried turnoff extension and still this is what i get

this issue has arisen suddenly over the last month. so i try to load bandcamp and for a few moments i'm able to go from page to page. after a certain short amount of time has passed between me opening the site and using it, just seconds, upon me clicking a link, pages initially appear to load [the refresh button switches to the X icon] before they quickly halt and keep me stuck on the same page. attempting to open a link in a new tab in this state gives a blank page - not showing as about:blank in the url but the intended destination. sometimes when i try to confirm a change on something i have uploaded to the site or try to log in, bandcamp gives an error reading "There was network error. Please try again."

so i originally thought it had something to do with using a VPN; initially i thought it was alleviated when i turned it off but i was wrong, problem soon reappeared. i've actually been using zen browser for a while, so maybe it was localised to that? i switch back to regular firefox and it was there too. troubleshooting mode didn't yield any difference either, so there's no conflict with extensions... clearing all bandcamp site data hasn't worked either, now because of this issue i just can't log back in lol. i ended up testing on a non-firefox browser, microsoft edge, and found that this issue isn't present there. so i'm kind of stumped on how to figure this out by myself now. keep in mind this is the only website that is affected by this issue

'bold text YouTube is "acting insane, sound plays/picture is frozen. Can't pause it. Also can't start it! Ads play on without option to skip. I got some notice that YT was changing something, I think it is broken. I managed to get a video to play on MS Edge, but I normally do not use that. I cleared cache and ALL of that, rebooted computer, etc. connection is good. Searches are fine on firefox, Other sites are fine on firefox. . IT IS YOUTUBE! It is SO bad that now with my mouse, the arrow and hand are NOT showing up on the actual screen where video plays. Right now on here it is fine. but on youtube? no.

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "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. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

The Merrill Lynch login screen does not appear. Ad blockers are disabled; the problem does not appear with other browsers. Screenshots are attached for the same site using FF and Edge. I asked this question a few weeks ago but never got an answer. I'm using FF 153.03 64-bit

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,

I started to notice recently that calendars in some websites I browse with Mozilla are inaccurate. The dates like months, days,... are in a mess. Then I used Google Chrome instead of Mozilla and it went right. It was accurate with Chrome browsing those sites. Did you hear of the same problems with Mozilla ? What can be wrong ?

Thanks for your insights,

All the best,

Denis

I recently installed an rtx 3060 12gb on my old system (Win10, ga-h77-ds3h gen3 mobo + xeon ivy bridge cpu). I installed latest Nvidea Studio drivers. Everything seems fine apart from Firefox, which showed visible artifacts/flickering lines on the screen. I disabled hw acceleration in Firefox settings and now instead of the lines I just see micro dots which change position frequently. As recommended by AI i changed some other settings in about:config but the tiny dots are still there. Starting Firefox in safe mode they are still there. On MS Edge its fine, there are no dots/artifacts.

Is there something else that might fix this or there is nothing that can be done, its just how the rendering engine works on older systems and rtx 30s cards?

Hello,

I'm seeking support to try to resolve an issue that has recently started happening. I can't be the only one who is experiencing this, so if this is resolved others can benefit too. I'm not a complete novice, but neither do I claim to be an I.T. expert.

I use my ISP's webmail service to access my emails. I'm aware I could use an email client, but I prefer to access via a web browser and have done so for many years. About a week ago, I was no longer able to sign in to my webmail. I thought it may be a problem with my provider, so I checked using other web browsers - Safari on iOS which worked and Microsoft Edge (using the same internet connection, same desktop PC) which also worked and continues to work without issue. I can only think it must be something wrong with Firefox? I can access the sign in page as normal using Firefox and select my email address, but after attempting to login I always get the same error message:

Sorry, we can't sign you in just now

Don't worry, it's just a quick pause to help keep your account safe.

Instead:

   Use a device you've signed in on before
   Try again from a familiar connection
   If you're on a VPN, switch it off and have another go 

Still stuck? If this keeps happening, get in touch with us (quoting reference IDF-12B) and we'll help sort it.

I have 2 extensions installed in Firefox - Adblock Plus and Ghostery. I have already added the specific URLs to the allowed websites list (first is the sign in page, second is what it redirects to):

mail2.virginmedia.com oauth.virginmediao2.co.uk

I have searched around for possible solutions, to no avail. Virgin Media advise only signing in on their main home page, but I've never done this as its just another step and extra unnecessary clicks. I don’t want to constantly be bombarded with news, offers and promotions every time I want to check my email, so I only use the direct webmail sign in.

I have tried clearing cache, cookies, etc. Then I tried to refresh Firefox, none of which worked. I also tried uninstalling Firefox, then using CCleaner to perform a clean up and registry scan to fix any possible issues, followed by a clean installation. To my surprise, I was able to sign in to webmail OK. However, the next morning, I got the same error. The only other settings I have tried tweaking is adding exceptions to turn off "Enhanced Tracking Protection" and "Block pop-ups and third-part redirects" on those 2 web addresses.

Any suggestions or options to try would be appreciated.

I've installed the 10.5.x version of Network on my Ubiquiti Gateway. I now have a problem accessing the gateway. However, this is weird. When on the local network, I can connect directly to it, no problem. Where the problem comes in is when I try to connect to it via unifi.ui.com, the web portal that Unifi Gateways connect to. I've tried a Private Window which is set to not enable any extensions. The results are the same. It will sometimes load part of the page, but never all of it. Before the v10.5.x Network Application update, this was not a problem. I've tried this on both a Windows 10 & Windows 11 computer with the same results. Everything works if I'm not trying to connect via the web portal from the local network. (i.e. If I'm elsewhere or use my cellphone's hot spot, I can connect to my gateway via the web portal without any issues.)

I would blame the Network Application update as the problem if it wasn't for one detail. It does work from the local network if I use MS Edge instead of Firefox. So, I suspect that while there was a change made in this update, there is also something that Firefox is blocking that Edge isn't.

Any ideas?

128.13.0esr This is probably a huge long shot I know, because every forum etc on the internet has nothing that ever helps with this, but as it only happens in FF I thought it was worth a try.

Yesterday I changed my Privacy settings to 'delete cookies when FF is closed' and added a few exceptions. Then this Google Search reCaptcha thing started. Changed it back to what it was, basically the default setting there, but it was still happening. It only happens in FF [doesn't happen with Edge] and only on one pc, all other pc's and phones in the house are fine [all using the same network, router etc]. So I uninstalled FF altogether, reinstalled it...this thing was still happening regardless of what settings I use re cookies etc. If I actually complete the super annoying reCaptcha it goes away for about 1 or 2 searches, then comes back.

If I'm signed in to a Google account it doesn't happen.

I even did a fresh Windows install [which actually fixed this the other time this was happening about 6 months ago] but that didn't fix it this time. There is no malware, no VPN, no extensions that I haven't been using for years. Nothing that could ever possibly be considered 'bot-like' behaviour.

Thanks

I am unable to sign into the iCloud web page on Firefox. I can sign in on Microsoft Edge, or on the Safari browser on my phone, so this is clearly a Firefox specific problem. When I try to sign in, the page skips the option that verifies my identity and goes straight to a message saying "Failed to verify your identity, Try again" without allowing the verification to occur. The verification would occur if the page would allow it to, as it does in the other browsers I mentioned. This was working fine last time I logged in a few days ago, so this is a new problem. I could switch over to Edge, but would prefer to use Firefox, if I can. Please help me. Thank you.

Trying to access search Home Depot, Lowes, Tractor Supply gives errors. Works with Chrome. Started about 2 weeks ago or so. I use Starlink, no VPN, tried disabling Ad Blocker, Clearing cache for Lowes, no Add ons, but still doesn't help.

Error msg from Tractor Supply is: Access Denied You don't have permission to access "http://www.tractorsupply.com/tsc/catalog/lawn-garden?" on this server.

When i try to insert a screenshot through the clipboard on google or yandex image search, the original image is corrupted. Even i try to upload an image via classic upload-button the same problem reproduise. On other sites there is no similar problem, as well as trying to insert the same image but inside the application windows.

In attachement: yandex/google and default image i was trying to upload.

Since the Firefox update to 152.0 64bit I have noticed that it takes two attempts to log into Spectrum email. The first time I try I get a IDID-4000 error (see below image) after entering my sign on and password. I then have to retry by selecting the bookmark again and then after entering my sign on and password a second time I can get in. This does not happen in Edge browser. I have tried deleting my sign on and password in my saved passwords in Firefox and then manually reenter my sign on and password at the prompt for Spectrum and then saving it again but it keeps happening. I have also tried turning off enhanced tracking, clearing cookies and site data, refreshing Firefox and stopping my Norton 360 and it still happens. There must be a bug in the new Firefox update 152.0 that is effecting the ability to sign into Spectrum as this was not happening before. I am wondering if anyone else is seeing this problem and is there a solution to fix this. Should I file a Bug Report about this? We should not have to jump through hoops or do some work arounds to try and get things to work like before as I have read with other questions having problems with 152.0 update. This update needs to be fixed.

Respectfully,

Facebook simply isn't loading in Firefox anymore - it loads in Edge on my PC just fine and on my Mobile Android Browser .

I've tried disabling all extensions, and clearing cache and cookies, but Facebook still refuses to load and returns the message, attached.
