Firefox Community Forum

I typically use FF to log into social security accounts. I have not been able to use FF for a couple of months to log in to ONLY THAT SITE. I can on CHROME.

When using BT Mail i am unable to input email address from drop down box which appears when typing intial first letters.

I can do this when using Edge.

I have updated my browser to latest version. Have also contacted Bt and have been advised that the issue is your browser. My wife has a chromebook and has no issue with the above problem.

Please advise.

Hello, Flightradar24 is not zooming or scrolling smoothly. In earlier FF versions this was not happening. Other browsers like Edge or Brave work fine. Perhaps you can take a look at it and fix it. Thank you.

I had to rebuild my Windows 11 this week. Since installing Firefox, streaming videos in Youtube are distorted with significant tiling during the first few seconds. The video has to be rewound manually to see the beginning unhindered, sometimes rewound several times because the tiling still happens, albeit less so with each rewind. I had to rebuild the Windows 11 because some mysterious problem, possibly from a Windows update a couple of months ago, caused a growling hardware contention noise during video or video games that would cycle through several harmonic levels and sometimes move across the stereo plane. Just before the rebuild it became continuous and untennable. The rebuild did not get rid of that problem completely, but there have only been a couple of tiny hardware contention noises since then. This tiling of Youtube video is brand new. The system is pretty much the same now as it was before the rebuild. I still have the old OS on another internal drive so it would be possible to compare files. I just want to know why all of a sudden Firefox is showing this momentary tiling in Youtube. I tried Chrome and there was no titling. Thanks for your time.

Problem started with Firefox 146.0.1 Windows 11

1. Open outlook.com in FF browser (https://outlook.live.com/mail/0/). 2. Open any email. 3. No side scrollbar appears so you can't page down within email. Note: the Outlook folder scrollbar does appear and does work. 4. The within-email-item side scroll bar does appear from outlook.com opened in Edge browser. So this is a Firefox bug.

Have tried: a. Windows settings->Accessibility->Visual effects->Always show scrollbars = on b. Turned Adblock on and off for outlook.com c. Firefox settings autoscrolling, smooth scrolling tried all combinations.

Any fixes?

This is happening since the start of Oct'25, if anyone has any idea how to solve this kindly help.

I am running the latest firefox version 147.0.3 64-bit. Gmail opens and runs fine on duck duck go and brave. Cannot find any info on how to solve/fix/override/whatever on "numeric code 4" but seems like other folks experience, too. I appreciate your help.

Today following a brief power outage I was no longer able to sign in to AOL with Firefox on my desktop computer. I am able to sign in to all other apps with no problem. I tried clearing my cache, restarted Firefox, restarted my computer and spent 30 minutes on remote desktop access assistance with AOL trying to fix the problem with no success. I can log in to my account using Chrome on the desktop computer and can log in with no problem using my Android phone but can't log in using my desktop computer with Firefox. I've verified that my Firefox version is updated. I am running Windows 11 Pro.

I would greatly appreciate any helpful advice.

Dans free.tv pourquoi la suppression des sous-titres ne fonctionne pas problème Mozilla ou Free.tv ?

The links on the site tasteofhome.com stopped working recently. When you click on them nothing happens. If you load the same page in chrome they work fine. Any suggestions? Or is this a bug Sample URL https://www.tasteofhome.com/recipes/chicken-and-bows/ but there are many more

Hello, the other day I asked the question why logging in to Hulu and The Hartford Ins. Co. did not work on Firefox, but did work on Microsoft Edge. I received some suggestions on what to try, but the problem resolved itself after a couple of days. Lo and behold, yesterday Microsoft ran an update to Windows 11, which they seem to do every two or three days!!!) and now I have the same problem with Hulu that I had before. I get the impression Microsoft is doing that on purpose to force users to use their browser and I resent the hell out of it. Any suggestions on how to get around this problem, short of running the updates? I'd hate to quit using Firefox when streaming on Hulu.

Gmail, Calendar, YouTube either timeout, or they render in an unusable state that looks like the html engine is broken. However, bringing up firefox in troubleshooting mode is fine. Earlier today I did update Java. Otherwise no difference. Other browsers are also fine. Firefox is my default browser so this is a bit unworkable.

For now, I will use Firefox troubleshooting mode...

Thanks David

on some sites, when I try to sign in I have entered my login information, but when I hit enter or submit for instance bigfishgames.com nothing happens. When I am on my Drs portal after I have entered pages of information and hit submit, again it does not get accepted. Soooo, I have to leave firefox and go to a different browser. Any help would be greatly appreciated, it is very frustrating when this happens. It is so frustrating that even though I have been on Firefox for many years I am thinking about using a different browser.

When I access a specific website the .css files hosted at http://cdn.ct-static.com/ don't load. The Network Tool console indicates that they time out. I have been told this is usually a network setup issue however if I use the MS edge browser the site loads. How do I troubleshoot this?

when I go to icloud.com to view and download photos and all my icloud stuff on my phone, I can no longer sign in using firefox. I turned off the shield security but no help. There used to be a pop-up that let you enter the code apple emailed you so you could access your icloud stuff on the web. Now there is no place to enter the code they send you. I enabled pop-ups too, but that didn't work. Help! I need my photos! And I use that site pretty much constantly-

Went to VRBO website to look at a reservation and the website, which showed me as signed in, showed nothing of the reservation. Said I had no reservation,, no history of saved searches. When I used Microsoft Edge, all my previous reservations, searches etc. were accessible. I cleared my Firefox cookies, etc. still had the same problem

These are the two opend email sites that I always use with no problems until this last few weeks, photos added show when links are clicked on the page and the resounding resaults.

I realy hope that someone can realy help.

So far all other emails that I receive open with no problems.

Thank you in advance.

after the last Firefox update the zynga game Farmville 2 will not load. It gives me a screen to fix mentioning chrome..but all efforts to manually fix referencing Firefox have failed. Odd that I can load the plain Zyngagames.com on Edge but it seems they too only load a "local" game that is not connected to any network. Help also mentions to make sure I allow to redirect but that "Options" feature to do so is not there. In fact it seems like the Firefox menu system is even much different and expanded. I will add the screens I have tried etc. Pop ups are allowed, turned off enhanced etc. but cannot find any reference to "third party redirects" Any suggestions are appreciated.
