Firefox 技術支援討論區

When attempting to play some videos with Firefox browser, mainly from X (Twitter) I receive "This video can't be played." However, I can't play them with Safari either. But it will play on Safari on another computer. I don't know what is wrong. Could it be some settings on my computer? I'm not a computer ace but know some things. Thank You for any help/ advice.

Hello.

I'm using VSCode debugging plugin for Firefox in order to debug my angular web apps. The plugin states that it only works when launching Firefox with "-start-debugger-server" argument. This launches Firefox with an interface warning, recoloring search bar bright striped-red with a warning "Browser is under remote control (reason: devtools)".

I would very much like to remove this warning, since I'd like to work in this mode all the time anyways. Is there any ways to do so?

Thanks, Anton.

For years I was able to view my credit card statements on the Synchrony Bank website, as recent as last year. Today, I cannot view the statements. When I click on the link I get the blocked symbol. (red circle with a slash through it. I am able to view the statements on another browser, Chrome to be precise. What changed? Can it be remedied?

There is a very bothersome extension that affects streaming of shows on Paramount +. It keeps reinstalling itself without asking me, to I allow it. Im attaching a screenshot of the extension, including its author, etc.

If I had multiple FIREFOX windows running, and closed FIREFOX down (not the multiple sessions, but the FIREFOX window) when I reopened Firefox all the sessions would start back up, even if I rebooted the computer. My HD failed, and now with the new system, I'm back to one Firefox opening with the home screen. How do I restore this feature?

As stated above: freac.org and GitHub does not open via Firefox (set as default browser)... (timeouts) Access is possible via Google, after signing in to old Google account. If if "settings"/exceptions,etc. need to be made, how to??

I had this problem in my last computer and I wasn't smart enough to keep the answer. Every time I look at a file, firefox downloads a copy even though all I asked to do was open it. What do I have to do to stop the downloads?

I have been using Firefox for YEARS. I love it, and have always been able to sign-in from a new device and have my bookmarks brought to my new device. For some reason, that is not happening this time.

When I click to sync or import bookmarks, the only options I have are Chrome, a couple others, and from Firefox HTML or CSV file. I do not know how to save the bookmarks. I would think that I could save them on a external hard drive and bring them over, but I do not know that process. It was so much easier when I could log in and bring them over.

Please help. I was so confident when purchasing this new laptop, now I am a bit irritated. Please explain how to bring my bookmarks over to my new device.

Thank you!

Good Afternoon, the FOE Helper extension stopped working properly with its latest update 3.6.2.0, specifically the event assistants. I have rest Firefox and reinstalled the FOE helper extension, still broken. It was working fine until the last update. Any ideas on how to get it working completely again?

a few days ago, Firefox stopped playing sounds. Any sounds. not youtube, not on Facebook. Not even porn videos. nothing. i don't remember installing any new software and Chrome plays youtrube sounds just fine. I listen on headphones and when i unjack, i still can only hear Chrome's browser play sounds. It seems like its not my comp, its the browser itself and it's only happened recently. i have yet to uninstall the browser and re-install, but i think if i use the Mozilla backup program to save my bookmarks, it will save whatever setting is causing the problem as well and re-installing will get me nowhere. anyone have any clue? i'm sure it's something simple but i cant figure it out

Hello - Over the years I have accumulated a lot of bookmarks over about six devices. Can I delete most of these on one device and then have the others Sync with it without repopulating the list with all the addresses that I've deleted from the first one? Thanks, Ian.

When I sign in to my bank, placing the cursor in the username box produces a number of username options, including the actual unsername and other mistyped ones from previous login efforts. I don’t want any unsername prompts. I went to Passwords in Firefox and made sure to remove the bank as a site to retain and offer such information when signing into that account. I continue to receive these username prompts. This doesn’t happen with other accounts. I cannot track down where that username information resides, how to remove it, and how to prevent Firefox from retaining this username information for this bank account.

This morning, my Firefox browser was unable to open so I downloaded it again and tried to sync up my browser using my email address. When I used my email address and reset the password, a much older version of my browser without all my bookmarks logged in. I've only use the *hidden for privacy*@gmail.com email address so I'm not sure if I have two profiles under that email. On my phone which has been sync'd to my profile for years, I have all the bookmarks that I've been using for year. I don't want to sync it now so I don't loose it.

Hi,

I use the latest FF for MacOS.

When I "close" Firefox by clicking the red cross in the top left corner of the window, I lose all open tabs when I start again despite having the option of restoring the previous session checked. When I "close" the whole thing (right click on FF in the Dock, Quit, and then re-open), all my tabs are back normally.

So basically every time i click this red cross, by mistake or not, I lose anything that's open.

Feels like I did not have this issue before.

Anyone has a workaround or experiences a similar issue?

Thanks!
