My problem is that Firefox will no longer allow me to login to my primary websites (email, bank, Costco, Apple...). I originally assumed that my outdated version of the MacOS was the problem, which was tied to the age of my outdated iMac hardware. Hence, I bought a new iMac, with the latest MacOS. Firefox still does not work. There is something wrong with Firefox and I don't know what it is. I have captured screenshots of the symptoms of what goes wrong with each website, but the one thing in common is that they are saying it is an application error on my end of the connection — which must be the browser (Firefox). I am being forced to do my daily business with Safari, but that is a strange browser for me, and they do not have my numerous Bookmarks. Also, their way of storing bookmarks is very strange, so I only have 5 — the ones that I have found so far that do not work with Firefox. There are probably more, maybe All of my bookmarks, but these are the 5 that I need every day.

Figure 1. Outlook (my email) When I log into my email, the result is Figure 1. This appears to me an application error on my side of the connection -- i.e., Firefox.

Figure 2. Costco.com When I log into Costco.com, the result is Figure 2. This appears to me an application error on my side of the connection -- i.e., Firefox.

Figure 3. Apple.com When I log into Apple.com, the result is Figure 3. This is Apple telling me there is something wrong on my side of the connection -- i.e., Firefox.

Figure 4. BankofAmerica.com When I log into my account at Bank of America, everything looks fine at first. But when I try to open my checking account, the result is Figure 4. This symbol, swirling forever, indicates something wrong on my side of the connection -- i.e., Firefox.

Figure 5. Hallmark.com When I log into Hallmark.com, everything looks fine at first. But none of the links will open, hence I cannot obtain any information about upcoming TV programs. This indicates something wrong on my side of the connection -- i.e., Firefox.

All the above examples work perfectly with Safari. Firefox is supposed to be the most up-to-date browser, so why has Firefox stopped working properly?

I'm using the latest Firefox. All of a sudden as of this morning, Firefox cannot not load Facebook or Twitter. I can open YouTube and YouTube videos appear but will not play (just a spinning wheel when I try to play). The Amazon landing page is scrambled with code. (see image attached)

I use Ghostery ad blocker but the issue persists when Ghostery is paused. I can use Safari without issue. Can anyone offer any insights?

Good morning,

Firefox is not loading webpages correctly this morning. From Gmail not displaying or opening individual emails, Amazon not opening, to Youtube and several other sites not loading or displaying correctly. I had no issues at 9 PM PDT yesterday.

No changes to the computer, and everything is up to date.

I have successfully opened the above mentioned sites and others on MS Edge this morning.

Thanks!

When using YouTube system freezes between 5-30 mins, of start of any video. I have troubleshooted, i have checked every extension, i have run every diagnostics on hardware and software , checked and updated every driver but no results i tried checking online but didn't file any solution , the only thing i can do is to reset my system, it does not happen in any other situation. This is happening since the start of Oct'25, if anyone has any idea how to solve this kindly help.

On all our computers it seems impossible to sign into Outlook...several laptops and 3 desktop...even a new Apple device. Enter your email address and then taken to the next page (see attachment). sign in works with Edge! This has been happening for maybe a month. Very frustrating! NEVER opens the next security window, the 'spots' just keep moving forever...selecting "Back" just repeats the cycle.

My problem is the following. The website of my favorite football club regularly embeds videos within their pages. Clicking of the video within the club webpage shows the video without leaving the webpage. Recently opening the club site with mozilla stopped enabling me to see the embedded videos. An example of what I see on my screen now when using mozilla is in the first image uploaded below - instead of showing the embedded video, all I see is a small red rectangle with a "play" button in it. If I press the play button, the video starts, but shows within the extremely small rectangle and I cannot watch it.

This is not so when I use Edge or Chrome, as shown on the second image uploaded below, showing the exact same webpage (the address is https://levski.bg/video/%f0%9f%94%b5-%d0%bb%d0%b5%d0%b2%d1%81%d0%ba%d0%b8-31-%d0%b1%d0%b5%d1%80%d0%be%d0%b5-%d0%b3%d0%be%d0%bb%d0%be%d0%b2%d0%b5-%d0%b5%d0%bc%d0%be%d1%86%d0%b8%d0%b8-%d1%80%d0%b5%d0%bf%d0%be/ ). The embedded video is clearly seen in its full size within the page, and when I click the play button it starts showing the video normally within the webpage without leaving the site and sending me to youtube, for example.

My question is, what is wrong and what can I do to start seeing the embedded videos normally again?

Thank you, Georgy Ganev

I was updated to 143.0.4 a couple of days ago. Ever since, I've had all kinds of issues. Some sites won't load properly. Some links are not clickable. We're talking sites I use all the time and have never seen this happen before. I have not changed anything in my firewall or antivirus and have used them for years with Firefox. I refreshed and nothing. I actually uninstalled Firefox, cleaned out the registry entries, and installed 143.0.3 today. And yes, I did set it to not auto-update. Still misbehaving. I don't know if I missed a reg key that might be the culprit. I'm currently using Chrome Canary - although it's not my favorite, it is working normally on the same sites I've tried with Firefox. I even opened Edge for the first time in ages - it's working fine as well! I love Firefox, but I don't know what to do at this point! Please, can you help?

Why do some websites not work fully on Firefox but work fine using Chrome or Edge? I had an issue with https://www.acmemarkets.com/. The product search feature of the web site did not work using Firefox but worked fine using Chrome or Edge. This has only recently started to be an issue.

Hi!

Firefox has been my default browers forever, but recently (i guess with the last update?) when I try and use google image search, when i click a thumbnail instead of making it larger and displaying, it opens up like a mini tab on the right side, which ends up with the image displaying smaller than the original. This seems minor, but I do enough image searches that this ends up making it unusable to me in practice. I'm hoping this is just a setting i havent been able to figure out how to switch off.

Thanks for your help!

Hi!

Please see attached image:

Left: Edge (making sure it isn't a network issue)

Right: Firefox using a new profile from about:profiles.

On my main profile, I've tried clearing the data and cookies (though not the history) a couple of weeks back.

Any suggestions welcomed! Many thanks in advance.

Gmail works on my phone (Android), Chrome, Opera, etc. It will no work in Firefox that I have used religiously for over 10 years. I've signed out of gmail and signed in...a dozen times. Nothing works. If I wish to read my emails, I switch to Opera

Why?

You know, I'd love to stick with Firefox as my main and only browser on my desktop. But it gets irritating when suddenly I can't use a web application or YouTube videos (like today) won't play or anything that forces me go go back to Chrome because THAT at least works consistently.

I find that many websites don't run on firefox. Examples are virgin atlantic, holiday autos and copa airlines. I have to switch to Chrome to use them. Considering that firefox releases updates frequently this situation is surprising. Is the firefox administration aware of this issue? Is there any way to overcome this problem?

This issue just started recently, say within the past 2 weeks Mid September forward.

Only happens in Firefox, Chrome not having an issue. Open Facebook tab and it opens fine then after 10-30 seconds, it crashes with this error "This page isn't available right nowThis may be because of a technical error that we're working to get fixed. Try reloading this page."

Have disabled all extensions, cleared cache multiple times with no success.

Appreciate any other suggestions on fixing as I'm not a big fan of Edge. Old school. lol

Thanks - Dan

Starting 6 weeks or so ago, my microsoft "on this day" photo link to view saved photos will not load.

I can view the page in chrome, so it's something that is specific to firefox, which has been my preferred browser for over 20 years.

I have not downloaded any new software or extensions.

here is a look at one of the page links-I just get a frozen greyish screen that looks like it wants to load but nothing happens no matter how long I wait. Although the screenshot I uploaded looks static, it has a kind of rolling feel to it, movement like somethings happening in the background...

I've followed all the suggestions, including uninstalling and re-installing firefox to no success...HELP!

For example when using Google translate there is an input delay, but it's only for Google Translate as other websites -- including other Google products -- don't have.
