Diễn đàn hỗ trợ Firefox

Just recently I am no longer able to use Bing.com to search with. Being it is my preferred source of searching for me. Google is awful for my purposes.

因工作需求，分别在五台电脑登录我的火狐账号（国内版账号），进行书签操作共享。 现在不知道因为什么问题导致，是火狐的历史书签没法多端同步（自动/手动均无效）， 其中尝试设置了 排障模式/about：config部分参数： ①contextParam--fx_desktop_v3； ②identity.fxaccounts.oauth.enabled设置为false，仍然未解决问题。 有解决方法方便直接联系3003378498@qq.com，求求大神帮帮忙，谢谢

Do you know of a mod that won't allow Youtube to have a resolution higher than 720p, including when embedded? I almost-always have Youtube at 480p when watching through their site. I noticed that when watching a video on another site and that it's embedding Youtube, that the resolution is higher > 480p and in those cases it's not rare to be > 720p.

I'd like a mod or setting so that when it's active that Youtube can't have a resolution higher than 720p, including when embedded. Any idea if there's something alike?

Thank you kindly for your help

While browsing youtube,i no longer find cast to tv icon in Firefox browser.Can you help me please,as after stroke my eye-sight is diminished.I was able to do it before,as i switched over Linux Mint 22 wilma,i am unable to find this cast icon.Thanks.

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

Greetings all, my trusty Firefox stopped working. Error Code PR_Connect_reset_error. Other browsers work fine. I have windows 10 with the latest updates and use Kaspersky Internet Security 21.3.10.391 (m). I have paused Kaspersky, uninstalled then reinstalled Firefox 3 times. I have cleared all Firefox cookies and caches a number of times. On my 2nd Firefox reinstallation Firefox worked ok for a couple of times then stopped again with the same error code. Please note that I am not very familiar with computer stuff so any suggestions need baby steps. Many thanks.

I use Primary Passwords on important sites. Since v136 installed this morning, no matter what site I OPEN Firefox to, even search sites, the Primary Password is requested. If Firefox is already opened, if I open the "unimportant" site, no password is requested.

After the recent bunch of windows updates i started noticing youtube loading much slower and other websites acting strange. Just now i tried to look at a link https://steamusercontent-a.akamaihd.net/ugc/47948470127416586/912CDEE3AD8B94CF3122B7338E89E24C9B6EC29D/

I get "No video support and MIME type found". I have uninstall/reinstalled, checked codex, disabled addons and downloaded Microsoft windows media pack, then restarted the computer.

Nothing seems to work. But i had to reinstall Firefox again because all my tabs would crash after the last reinstall.

For the past week now, every time I go to this link https://marketplace.secondlife.com/ , it is in another language. Usually Spanish or Portuguese and now and then French. I'm always having to translate. Even though my settings says English and i have no other options.

I have been setting up Passkeys to log in to the websites which allow them. But I have noticed on Paypal, they do not allow me to use passkey when using firefox, it only seems to allow chrome

Is there an issue with firefox which deems it not suitable for passkeys?

I noticed that sopmeone asked this question this time last year and it was advised that firefox is now able to create and store passkeys Paypal still dont seem to allow it?

Why are these showing up now? They were never there before. Is there a way to hide them or make them disappear? They are ugly, distracting to look at and unnecessary. I tried one about:config solution, but it did not work. Please fix this. See screenshot. The black tacks should not be visible, but now they are.

Why can't I use "Restore Previous Session" any longer? It used to be a way to recover tabs when the program unexpectedly crashed, but now it's shown in gray and I can no longer click on it

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

Hi,

I am the developer of the Dictionary Anywhere extension which is a Firefox recommended extension. Recently my extension stopped performing up to its expectations due to backend changes in public API that it uses to find meaning of the words.

However, I am unable to modify the code of extension to fix the issue as I am not able to login to my account due to it being behind MFA, and I have lost access to the phone which contains those MFA codes.

Can something be done here, to allow me to update the extension to rectify the issue that 50k users who use this extension regularly are facing? For example, can the extension be transferred to another account through which it can be updated, lots of users are suffering as the extension is not working. I have access to the source code of the extension .

Thanks and Regards

Installed 134.0.2. Bookmarks disappeared. Went to restore backups, receive message "unable to process the backup file". All of my bookmark backup files receive this message when I try to restore.
