Firefox 技術支援討論區

Firefox crashed and I couldn't get it restarted. I had to uninstall it and reinstall it. I lost all of my bookmarks, logins and other information. What do I do to recover it?

Why is this so difficult? I keep getting the attachment. How do I stop it? I NEVER WANT FIREFOX TO TELL ME THERE IS AN UPDATE. I will check and update when I'm ready. How do I stop this?

I have two monitors, and I usually keep a stream/youtube video open on the second monitor while I browse the internet/play games. I used to do this all the time in OperaGX, but I recently changed to Firefox, and I've noticed that after about 10 minutes, the video or stream stops playing, and I have to manually pause and unpause the stream to get it running again. I have checked online, and I found a fix related to the about:config setting "network.http.throttle.enable" as "false" and the "network.http.throttle.version" as "1", but my firefox already had these settings like this.

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

Hello all. I'd like to restore the backspace button function but the previously workable solution — resetting browser. backspace_action to 0 — is not working for me. Any hints as to why that might be the case?

When I sign in on my Microsoft Account FF Password Manager Does nothing. I open up the passwords but the manager does nothing. How do I correct this? It is as if FF does not recognize I am being prompt for login info. This only happens with this cite. Thank You for your time Mike

Firefox has been my default browser for longer than I can remember. Over the years, I have maintained a significant bookmark file for work. I recently purchased a new computer, and my zero bookmarks from the new computer have replaced all of the bookmarks that I had in my old browser. This is a bookmark file that has successfully followed me through multiple computers and even my ios devices. And now it seems to be completely gone. I've looked at the places.sqlite files, and the largest one is 20MB and is in my current default profile, but it is dated today. That makes no sense because I do not have any bookmarks on this older computer, and my new computer doesn't have any either. The bookmarks have also been completely deleted from my iPad, but miraculously are still on my iPhone (evidently I had signed out of Firefox for iPhone at some point so they do exist somewhere.) The thought of trying to rebuild my bookmarks is nauseating. My only thought is to sign out of the browser on all devices, then sign back in and sync on the phone. Would that repopulate the main file with what's on my phone? Any other ideas?

I am suddenly getting pop-up windows from "Firefox Software Updater" as soon as I click the Firefox icon on my desktop (Windows 11) and laptop (Windows 10). The Firefox log in the pop-up is not in color, so I am immediately suspicious. The pop-up window did not happen on my laptop yesterday, but I got it on my desktop today, for the first time. I have answered "no" to the "do you want this app to make changes to this computer?". Is this legit from Mozilla? Usually, the browser updates automatically when I click the icon, saying I am now using the latest version of Firefox. Thank you.

After updating to Windows 11, all my Firefox webpages backgrounds are colored black even after choosing a light theme which only changes bookmarks and toolbar to white. I want white background like my old Firefox ?

So I've noticed that after putting my computer to sleep, upon return Firefox will be unable to load any videos from seemingly any site. The temporary solution to this is to reset my computer as sign offs, locks or returning to sleep do not clear the issue. I've tested on different browsers/sites and can confirm that this is exclusive to firefox. I have booted firefox in troubleshoot mode, cleared my history and given the sites time to load with no luck on any of them.

Is there a solution to this?

I get phone notifications that a streamer is live but when I go to their page on Twitch on my laptop, I see them as offline (screen shot).

I've tried clearing cache and cookies and do not currently have any pluggins that affect Twitch.

I have just reinstalled windows and then Firefox. If I click settings then a menu item it just freezes.

I have uninstalled and reinstalled.

Using Windows 11 Pro 22H2.

Any suggestions?
