I cannot get certain videos to play on Firefox. YouTube, Instagram, Tumblr all can play videos. Pretty much everything else doesn't work. Patreon, I get a black screen. On Twitch, I can only see the 'not currently streaming' screen, even if they're currently live, and VODs don't work. My computer specs are below. Operating system is Windows 10, I use Windows Defender for anti-virus. Everything works completely fine in other browsers. Here's everything I've tried to fix this:

• Updating Firefox
• Updating my computer
• Running in Incognito
• Running in troubleshooting mode
• Allowing autoplay
• Disabling hardware acceleration
• Disabling addons
• Clearing cache and data
• Enabling/disabling DRM content
• Installing Windows Media Pack

My specs: Processor Intel(R) Core(TM) i7-10700F CPU @ 2.90GHz 2.90 GHz Installed RAM 32.0 GB (31.8 GB usable) Storage 932 GB HDD TOSHIBA DT01ACA100, 477 GB SSD Micron 2300 NVMe 512GB Graphics Card NVIDIA GeForce RTX 3060 Ti (8 GB) Device ID C6C4BD2F-BD36-40B6-A917-13896770194D Product ID 00325-82058-09721-AAOEM System Type 64-bit operating system, x64-based processor

This has been going on for over a year now. I've gone through all of the above troubleshooting steps multiple times. The only progress I've made is getting YouTube from nonfunctional to working again.

Please take a look at the screenshot. When I try to log into my Amazon seller account, I get this screen. I uninstalled Firefox and then installed the latest version. That didn't change anything. I can log in with Google Chrome.

Hello, my pc recently crashed and burned and won’t boot up. In anticipation of building a new pc, I’d like to retrieve my passwords and bookmarks from the broken pc. I made the mistake of changing my Firefox password and saw at the moment I pressed reset it said I’d lose everything. Of course I found the password for Firefox after the fact smh, but I’m wondering if I can retrieve the info from the broken hard drive and transfer to the new one. Is this possible?

I do not want to start fresh install, I would like to be able to clear my old data. When I enter form data all the old stuff shows up, but none of the new.

Is there not some easier way to clear this?

I tried using Firefox on a new device, I wanted to sync with my previous settings to just restore them, I was unable to remember the password at that time so I reset it, after resetting it it still didn't work and different problems came up so I tried fixing it in a different way. Long story short im unable to connect my current profile (which I used previously with that email) with that account, so im also unable to start any ways of syncing as only this message appears

"This profile was previously synced to a different account

To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using email, create a new profile."

Right now im just using a backup which basically restores the profile, but if im doing something on one device it shouldnt sync to the other one, whats the best way of fixing it, is there a way of desyncing the profile with the mozilla account or start a fresh profile but slightly alter some values so I can use this one?

Kind Regards

i went to about:config -> browser.translations.enable and also browser.translations.automaticallyPopup , making sure it reads "false", and also went to Firefox Menu > Settings > General > Language and Appearance and under Languages the only language other than spanish (the language i want the browser to be) is english (maybe that way it recognizes it as an "allowed" language or something and doesnt translate from it)

...but it still translates pages from english (sometimes even translating the search result and directing me to a translate-version of the page instead of to the the page itself).

how can i make it not translate things from english anymore? (if the only solution is to stop translating altogether from any language, i'll gladly take it as long as it stops translating from english)

我在使用 Firefox（最新版，作業系統為 MacOS）進行線上付款時，遇到信用卡 3D 驗證無法成功的問題. Yahoo及蝦皮都無法完成驗證（交易OTC）。購物流程進行到付款畫面，點擊「送出」後，3D Secure 驗證視窗完全沒有跳出，或者跳出後顯示錯誤，導致交易一直失敗。我停用了廣告阻擋及防追蹤的擴充套件，情況依然存在。

請協助檢查 Firefox 在 3D 驗證流程中的可能相容性或彈出視窗問題，感謝！

In the past, I've always relied on the 'Recently closed windows' option to retrieve my session when Firefox closes unexpectedly. However, lately, seemingly every time Firefox is closed out and then opened up again, 'Recently closed windows' is blanked out and the only option available is 'Restore previous session'--which, almost invariably, does not work and instead simply opens up a new instance of the homepage in a new window. Is there some way to disable the session restore functionality? Or to get 'Recently closed windows' to actually store my recently closed windows?

Trying to access a court site, and it won't take my credit card info form payment until popups are disabled. I don't recall every enabling popups, but that may be automatic when browser is loaded/updated.

I can't check this block on this page (Email me when someone answers the thread). If there is criteria for checking the block, why don't you post the criteria?
