Firefox コミュニティフォーラム

I have at least one question on the support forum which has never been answered. So I went to Bugzilla, and discovered dozens of YouTube issues under the Open/Unconfirmed status.

I can reproduce my problems. I'm sure others can reproduce their problems. Nothing is done. NOT EVEN admitting there is a problem.

If I can't use YouTube on Firefox (I can't), then why am I using FF? It is one of the biggest sites on all of the internet. But FF apparently doesn't care if it doesn't work.

What. Is. Going. On?

All of a sudden I cannot check out using shop on my IMAC. It has worked for me for years and now all of a sudden it stopped. Not sure what settings to edit. I can go through the check out process, but when I press check out the page will not load. I just get a shadow & spinning like it's trying to upload but it never does. If I switch to Safari I have no problems, but I prefer Firefox. Any suggestions or solutions appreciated. Lorri

Hello,

I'm trying to access a dropdown menu on trafficjunky.com but the menu is not functioning correctly and will not load. When I select the dropdown, it opens a small blank white box that should fill with options, and I should have the ability to free type as well so I can search for a location. This does not happen, the only thing that happens is what you can see in the picture and free type is not functioning.

I have cleared cookies and cache numerous times, updated my browser, deactivated extensions, turned off performance settings, and have tried both troubleshooting and incognito modes as well. I am not running ad blockers or themes on Firefox.

Any advice you can provide is appreciated!

Thank you, Kyle

Dear Firefox,

When I copy and paste from Pages on a Mac, to a gmail email I am writing, I lose all the formatting. This doesn't happen when using a Brave browser, so I don't think its a gmail settings issue.

Can you help?

Is there a setting in Firefox that I could use to overcome this issue?

Thank you,

Hello Team

The .NET 9 BLAZOR web applications are a bit clunky on Firefox. The Firefox browser always gives Rejoining server and this is not happening on Chrome and Edge browsers. Can you help here to resolve this?

Thank you CK

Every few Google searches, I get an unsual traffic message with a captcha to prove I'm human. This only happens with Google searches and I don't have the same issue on Chrome or Safari (I'm on a Mac). This only began about two months ago.

It's driving me nuts. I love so many things about Firefox, but this has been going on for months, and I'm about to give up. I found some "solutions" about privacy settings, but none of them have worked so far. I have changed IpV6 settings, privacy settings in about:config, and proxy settings in Firefox. Nothing has stopped it.

This only happens when I search on Google. It seems clear to me that Google and Firefox are not playing well together.

Is anybody else still experiencing this? Has anyone found a solution other than what I've noted above?

Firefox is my default browser. The problems have arisen from around December 27th 2025. Till then everything worked smoothly. The first problem is that if I go to google.com then search for say , “Wordle”. The search output is displayed on the screen but when I click on the search result, it does not go anywhere- nothing happens.

The second issues, is till the problem cropped up, I had set google.com as the custom url for home page and windows through settings, home, and had used an extension, “ New tab override” available from Firefox, to set every new tab to open as google.com The url for the webpage works but the new tab override does not. I have tried removing the extension but problem 1 persists.

The third issue is that I have subscriptions to newspapers and had set up the logins. These newspapers are in my bookmarks. When I click on the bookmark the main page opens but the login area is missing. It tells me to get a subscription. e.g., among others, NY times, Uniqlo gb, the Turnitin of my university will not load although I am logged in to the university. I have cleaned all cookies, removed all extension including Ad blockers to fix the problem, tried resetting all to default setting but nothing works. Would appreciate any help you can provide. Thank you.

In order to connect to Amazon using Firefox on my PC, I am required to scan a QR code with my phone and then, presumably, connect via Firefox or Amazon apps (instructions woefully unclear). It NEVER works. It's no big deal, but it is annoying, particularly since I want to use Firefox as my default browser. I can always connect via Google or Edge. For those of us who aren't tech savvy, why don't you add standard two-factor authentication or Windows Hello as an option?

In Firefox, the animation exhibits performance issues like stuttering, particularly in elements that rely on animateTransform and animate for movement or opacity transitions. This issue is not present in Chrome, where the animations run smoothly without any noticeable lag.

Expected Behavior: The animation should render smoothly on both Chrome and Firefox without any stuttering or lag, providing a seamless experience for users.

Steps to Reproduce:

Open the provided SVG code in Firefox.

Observe the animation, particularly the elements with animate and animateTransform attributes.

Notice the stuttering or lag compared to the smooth rendering in Chrome.

When I try to connect to the SSA login site, I get this message:

"Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

If I use Microsoft Edge, the login works fine.

I can not login to my Vanguard.com account Called Vanguard and they said they were having major problems with people using Fire Fox as their server. I can use Safari and everything works fine. Please advise.....

Every time I get an update, it scares me. The latest update took uploaded a file using firefly. Could I do it using Chrome - yep - it uploaded my file without any issues. I keep hanging on to firefox but I need to changeover. The constant updates should be be happening.

I can login to my iCloud account with Chrome with no issues. Using the same User Name and Same password in Firefox it will not login. Instead it wants me to use different password. I know the UN and PWD are correct as I use Roboform password manager AND I can login using that data using Chrome. That tells me it is a Firefox issue?? HELP

certain web sites are not available on my PC via firefox browser. Have to switch to Edge to access. Have had this happen a number of times for different websites but was amazed that couldn't access social security admin (ssa.gov). Received this error message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

Thank you

I am not familiar with settings, therefore I am unable to get a few of my pogo games to work. One of the games is Jungle Gin., no cards. On the Browser EDGE I can play Jungle Gin. I have been told it is a software problem with Mozilla. Please fix it for me. Thanks
