This morning, I can no longer download (Save) files to my computer, nor check/change settings in Firefox. Tried all troubleshooting steps to no avail.

If I delete and reinstall Firefox, will I lose all my Bookmarks, etc.? Running version 157.0 (aarch64).

Appreciate any help!

I hope an email translation feature can be added to the application, similar to Gmail's, making it more convenient to translate the content of emails written in foreign languages.

I checked the parameters:

full-screen-api.ignore-widgets = false browser.fullscreen.autohide = true

I restarted File Explorer, the browser, and the PC; the problem only occurs in Firefox. At the same time, if I press F11 in advance, then when I press F again or open a full‑screen video with the mouse, the taskbar no longer interferes. I tried running the video in incognito mode, but the problem persists.

I've set my local open-webui as the browser.ml.chat.provider as https://llm.local/ and upon right click to a page and saying "summarize this" the side bar is opening. But the prompt doesnt get pasted to the webui.

Doing that while the sidebar is already opened works fine!

Any suggestions how to fix this?

When I hit the free Firefox Free VPN limit of 50gb, I purchased one year of Mozilla VPN. At first it worked, but now Firefox denies access to any website if I have Mozilla VPN!? What is causing this. Also now that new month Free VPN will not turn on as says I already have another acount, ie Mozilla. When force a start page if gives me a Firefox page without any of my bookmarks.

Since the Thunderbird update of 30 Sept the ability to attached files to my emails has 'vanished'. I press the attach 'button' but there is no response. Never had this as a problem before. I am running Windows 11 home version. Help!

I mostly like the UI changes. However, I have a persistent bug where there is an unremovable blue alert icon on the sidebar/history button. Aside from removing this button from the UI completely, is there any way to dismiss this alert?

Second question: while in the sidebar, I navigated from History to Bookmarks. I no longer have the ability to change the sidebar away from Bookmarks. How do I get History back?

I Accidentally signed out of my account and then had to change my password, now all old passwords and bookmarks are gone! Help to restore please. Now when I sign in, it's with the new password and I can't access any of my old back-ups.

Google maps displays a map and then, a few seconds later the map goes black. I found an archive thread called "Google Maps suddenly displaying black" where it is suggested to use ctrl+F5 to bypass the cache. That solution works but then, a few seconds later: Boom, the map goes black.

Seems to me that when the page is refreshed by a script in the map that whatever gets downloaded corrupts the map and then when the refresh occurs, the map goes black.

What ever this "corruption is" Firefox fails to display the content correctly. I have killed my cache, disabled extensions, used troubleshooting mode, switched to the "auto" system theme etc. The key combo is the only way to temporarily recover the map. I should also point out that I see differences in the map UI, it looks like Google updated the UI in maps.

Добрый день! В отправленных сообщениях пропали сообщения за последние два дня по адресу ak@ava.proekt.ru, как их восстановить?

Hello, So my thunderbird updated yesterday 10/1/2026 and since then it's changed my layout and also making problems in attaching documents etc. Is there a way to revert to the last version? Or does someone have a way to fix this problem?

Hello, I am using the latest version of Windows 11 and Firefox, but I still do not have the built-in VPN. I have had the VPN option for over a month at work. Why do I still not have VPN? There is no option in Settings for VPN either.

Thanks

Is there any way to bring back the previous version of history that's sorted by most visited?

Like, why bring over the other sorting methods but not this one?

I know there are people that are going to be "well, why don't you bookmark the sites that you keep going to"? Because I prefer it this way. My history is my "second bookmarks" list in a way since my normal bookmarks are bloated and cluttered enough as it is.

I’m requesting help troubleshooting a microphone/audio issue with ChatGPT in Firefox.

Computer/network information

This is my personal home computer, not a company-managed computer.

I am using my home Internet connection.

Firefox version: 157.0 (64-bit).

Firefox reports that it is up to date.

Firefox’s start page also displays “What’s new in Firefox 157?”

Microphone: Logitech Brio 101.

Problem

ChatGPT Voice does not recognize my speech when I use Firefox. The ChatGPT Voice interface starts and appears to be listening, but nothing happens when I speak.

ChatGPT’s separate dictation feature also fails to transcribe my speech in Firefox.

The important comparison is that ChatGPT Voice works correctly in Google Chrome on this exact same computer, using the same Logitech Brio 101 microphone and the same Internet connection.

What we have tested

Verified in Windows Sound settings that the Logitech Brio 101 is the default microphone and that its input-level meter moves when I speak.

Confirmed that the Brio 101 microphone works correctly in other applications, including Zoom.

Confirmed that ChatGPT Voice works correctly in Google Chrome on this same computer.

Checked Firefox permissions for chatgpt.com. Firefox is allowed to use the microphone.

Firefox displays the red microphone indicator in the address bar when ChatGPT attempts to use the microphone.

Reset the microphone/site permissions for ChatGPT in Firefox and granted them again.

Changed the Firefox microphone permission to “Always Ask” so that Firefox would prompt me to select a microphone.

During that prompt, Firefox initially showed an External Mic/Sound Blaster input. I explicitly changed the microphone to the Logitech Brio 101 and granted permission.

Even with the Brio 101 explicitly selected, ChatGPT Voice still did not recognize my speech.

Changed Firefox Autoplay permissions for ChatGPT to Allow Audio and Video.

Verified that the ChatGPT Firefox tab was not muted.

Started Firefox in Troubleshoot Mode to disable extensions and other customizations. ChatGPT Voice still did not recognize my speech.

Tested ChatGPT’s separate dictation microphone in Firefox. When I speak, the visual indicator dots react to my voice and become darker, suggesting that microphone activity is being detected. However, no speech is converted to text.

Opened the Firefox Web Console with Ctrl+Shift+K, cleared the console, started ChatGPT Voice, and repeatedly spoke into the microphone while monitoring the console. ChatGPT still did not recognize my speech, and the Web Console remained blank with no error messages displayed.

Repeated the test in Google Chrome. ChatGPT Voice works correctly there using the same computer, microphone, home network, and ChatGPT account.

Current findings

The Logitech Brio 101 itself appears to be functioning correctly. Windows receives its audio, other applications receive its audio, and ChatGPT Voice works with it in Chrome.

The failure appears to be specific to Firefox. Firefox appears to obtain microphone access and even detects microphone activity during ChatGPT dictation, but ChatGPT does not receive usable speech/audio for Voice or produce a transcription through dictation.

Because the problem remains in Firefox Troubleshoot Mode, it does not appear to be caused by a normal Firefox extension.

Could you please advise what Firefox-specific diagnostics or settings I should check next? I would particularly like to determine why Firefox appears to receive microphone activity from the Logitech Brio 101 but ChatGPT Voice and dictation cannot process the audio, while the same features work correctly in Chrome.

Hi!

I'm trying to use Widgets in the Home page, but I can't find the option to enable them. Following [previous solved question], I checked that I have the "Allow Firefox to improve features, performance, and stability between updates" option enabled, have restarted and updated Firefox, but I still can't find the option. Should I check for other configurations?
