Firefox 社群討論區

I've been searching for three days now for a solution that will work to restore my profile from a crashed windows-7 machine to my new windows-11. Nothing listed in any forum or help desk works as described. I used to be able to just rename the folder to the exact file name on the new PC, but windows 11 won't let me do anything. It always needs admin permissions and even after I activated the admin account and assigned a password, I still cannot copy to the folder or rename the folder. Every attempt to do this on W-11 fails. It shouldn't be that hard and I'm tired of wasting days playing with this. I have important bookmarks, passwords etc. I want restored, and I need help. Nobody wants to pick up a phone anymore to assist!

I have never used "sync" because I have multiple PCs and each used for different applications and yes some go back to W-7, the operating system that actually worked well. Each PC has Firefox and a distinct bookmark file.

I went to "about:profiles" and created a new profile thinking I could copy to the new folder, but when i switched profiles I couldn't get back to the original default! HELP!

When I click on the search box in the middle of the New Tab page and start typing, the focus automatically jumps to the Address Bar (Awesomebar). I want the typing to stay within the central search field.

In about:config, I have set browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false. However, this did not fix the problem — the input is still being redirected to the top address bar.

www.russellmoccasin.com won't load properly on any browser on my macbook pro running Mac OS 15.7.3. I don't have any browser extensions running, I've cleared my browser history, cookies, and cache. Still won't work. When I disabled javascript on safari and firefox, the website loaded perfectly. But I have to have JS running to use almost every other website on the internet, so what gives??

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

I'm afraid I picked up malware despite Sophos due to this message upon routine searches, e.g. "Where's the nearest pet store". About this page Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen? IP address: 206.194.252.88 Time: 2026-01-13T22:42:41Z URL: https://www.google.com/search?q=Pettstores+near+33069&ud m=14&sei=YMpmafbPMZyKwbkPzc23sAE

It's preceded by the reCaptcha request to check the box stating I'm not a robot.

I'm afraid to enter any passwords on here, to order anything, and especially engage in banking. I'm in a rental using WiFi, Thank You, Eileen

Previous solution: switch browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false does not work anymore.

Please help.

Why hasn't firefox 147.0.4 updated to firefox 148 ? The computer is windows 10 home 64 bit that is enrolled in extended security updates. The update has been released a few days ago I believe, in Canada,also I;m wondering if there is a button that is available in "about:config" that forces a update check. Thanks James

Hi, I am using Firefox on Mac Os Tahoe and IOS 18.7 and 26.2 (2 iPads). I have set up synching of my open tabs, but this works only from MacOs to the iPads, not the other way round. When closing MacOs Firefox tabs on the iPads this does not synch back to the Mac. I am missing something?

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

[article] This article claims there is an "AI Controls" section in Settings. This is not found in v 147.03 (up to date) for Mac. Please let me know how to disable all AI in Firefox.

I always have multiple tabs open in my browser. Previously, I could easily open (and switch between) 20+ tabs (I have 16GB of RAM). Recently, after opening five tabs, the Task Manager shows 10-11GB of RAM (88-90%) in use! How can this be? I cleared the cache and history, but it didn't help. I installed several RAM cleaners, but none freed up the required amount. None of the five programs worked. Where does that 15GB of RAM go when I open Firefox? When will you finally implement something like Google Chrome—they free up RAM for active pages when inactive ones are opened. Maybe it's because I have so many inactive tabs that the RAM is disappearing? But I had just as many tabs before, some of them inactive, and fewer than 20 active ones, so I could easily open another 20. And now I can't even open five new ones. What's happening to the browser?! SOS!

After being prompted to update the browser this morning, and after I updated it, I can no longer use ChatGPT. Chat GPT will open, but it's unresponsive, can't log in, the arrow button to submit an inquiry doesn't work, and none of the other features of ChatGPT are working

I've tryed all obvious instructions and my bookmarks toolbar will not sync

Every time I try to use my camera or microphone on some websites from on firefox it says can't detect camera or microphone? It doesn't show up with the 'allow this website to access your camera/ microphone' pop up it does with other websites. I went into permissions and manually changed it myself and it said it still couldn't detect the camera/ microphone

Desktop Firefox 147.0.3 (64-bit) When I open Facebook, pictures of accounts are continually blinking (not flickering). This problem is new and appeared just after last Firfeox update.

After updating to Firefox 147 from 146, it seems that some areas in page rendering are becoming corrupted.

Using the attached example from https://soundcloud.com/solarstone/tracks, it is possible to see a corrupted song bar. In the other song, where the full bar chart should also appear, there is a black area, which seems like a different kind of corruption where the content is simply not being displayed.

This did not happen in version 146.

Is there anything I can do, or any information I can provide, to help debug this issue?

Thank you.

Just as the summary says, Used to have an icon that I put under the "hamburger" menu on the bookmarks toolbar that opened the bookmarks menu. Can't remember how I got it there. Can someone help me get it back.
