Firefox 社群討論區

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

ive searched every article from here and beyond, but i cannot seem to find the button to edit my payment information. strange since it still prompts to autofill it

Please stop adding AI to your browser. It is making it slower and is a data privacy concern for me as well as many others. If you do not remove them I will be switching browsers. AI is not only bad for the environment, it does not even do the features you want it to do correctly. Please remove AI from firefox, i have been using this browser for years and would hate to leave because you refuse to remove AI features nobody asked for.

I use Firefox for privacy, lack of bloat, and other ethical reasons. For these reasons, I don't want to have the new CEO keep the incorrect idea in his head that the people who use Firefox want AI. Please don't add more AI, if anything--- please remove the AI which has already been added to Firefox which users have to remove themselves. I will dump Firefox if the new CEO continues with this plan.

I can't seem to locate how to activate the microphone in the AI sidebar. I have Gemini selected, and when I hit the microphone to dictate I get the following message.. Unable to access the microphone. Please check settings.

I looked through Firefox settings and my laptop's but I don't see where it is turned off or asking for activation.'

The 2-year-old support page "View synced tabs from other devices" gives 2 methods for syncing all your tabs from one Windoze FF to another. Neither one does anything at all for me now. The "right-click on the device in the sidebar" sounded SO promising, but it does not cause anything at all to happen. And checking the "sync tabs" box does indeed make them all show up in the sidebar list, but does not open anything. So besides clicking on each of the hundreds of tabs listed, how can I do this, or is it just another FF functionality lost to time?

Issue Description: I’m experiencing a problem with fullscreen mode while using YouTube on Firefox on Windows 11 with a dual-monitor setup. When I enter fullscreen, the video does not cover the entire screen. Instead, I can still see parts of the Windows desktop or background around the edges of the display.

This issue only happens on Firefox and only when using fullscreen mode on one of my monitors. I have already checked my display settings, scaling, alignment, and hardware acceleration, but the problem persists.

System Details:

Windows 11

Dual-monitor setup

Browser: Firefox (latest version)

Issue: Fullscreen video shows borders and does not fully cover the screen

Expected Behavior: The fullscreen video should completely fill the selected monitor without showing any part of the Windows desktop.

Please advise on how to resolve this issue.

Hello,

I am experiencing an unwanted UI behavior in Firefox. When I select text on any webpage, Firefox displays a floating “Ask ChatGPT” bubble above the selected text. This happens regardless of the site. I want to disable this feature, but Firefox provides no setting or preference to do so.

This is not caused by any extension. I verified this by checking about:addons, and I only have the following extensions installed:

DuckDuckGo Privacy Essentials

Firefox Translations

Gibiru for Firefox

None of them inject any ChatGPT functionality.

I then opened about:config to disable the feature, but the usual preferences do not exist on my system. Keys such as:

ui.textSelectEnabled

browser.selection.menu.enabled

browser.ml.chat.enabled

browser.ml.chat.openai.enabled

browser.ml.enabled

are missing, and Firefox only shows the “add new preference” (+) icon. That means Firefox did not expose any toggles for this behavior.

I am including a screenshot showing the unwanted “Ask ChatGPT” popup that appears when selecting text.

I need instructions on how to permanently disable this text-selection popup, or confirmation on whether this is part of a controlled rollout or experiment that cannot be disabled on my version of Firefox.

Thank you.

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

Since the 145.0.2 update web pages are loading very sloooooooow. Also, images are loading very slowly, if they load at all. At the start pages would not load at all then about a week they started loading but very slow as mentioned. Any ideas/help will be very much appreciated. I am using Windows 11.

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

I use Firefox specifically because I appreciate(d) the flexibility and the privacy. Default AI makes it significantly more difficult to customize the browser to my preferences (ie, zero AI anywhere) and threatens the privacy that Firefox is known and recognized for. This is an absolutely incomprehensible decisions; it is no longer a "trustworthy" browser if it incorporates AI. Why ruin a good thing??
