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.'

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

I have Firefox set to use the built-in .pdf viewer to avoid Adobe's intrusive AI features. I have disabled Adobe's AI features in the Acrobat settings, that does not seem to apply when Firefox opens the Acrobat reader. Consequently, I have to fight off AI "suggestions" and offers of help when I simply want to read a document from the web.

So I set Firefox to use the built-in reader. After 1-2 seconds, it switched to Adobe, and brings up all the annoying AI features. How can I keep Firefox from switching to Adobe?

As a test, I renamed Acrobat.exe to AcrobatX.exe. Firefox behavior did not change. I also killed all Acrobat-related tasks in Task Manager. My document still displayed in Acrobat after 1-2 seconds, but none of the Acrobat-related tasks reappeared in the Task Manager.

I am using Firefox 145.0.2 64 bit in Windows 11 with all updates current.

Many thanks for advice.

The lack of a title bar makes it impossible, for example, to close the application by pressing the "X" icon in the upper right corner. The title bar does not appear when the application starts, but does appear when the application window is minimized and then maximized.

Firefox is preventing me from going to certain websites because it is telling me I am using adblocker but I have none installed.. I am trying to play around with the settings but I still can't do it. Is there an inbuilt adblocker? I need help please...

I really miss the home symbol (a little house), as it allowed me to go back to the original page- blank. I could just start over without having to clear the address bar. It was way better than without it. Any way I can get it back?

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

I don't remember when it started but text that wasn't underlined before such as: Names of shortcuts in new tab view Titles of YouTube videos on home page, and recommended while watching a video (not on the video itself) Reddit titles and usernames (old UI)

I have checked settings as best as I can and tried disabling all extensions but still have the issue.

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.

[^1]: 145.0.2 from the Mozilla Debian repository.

I run the current Firefox version under Windows 11 Pro on a Dell Inspiron 15 3530 laptop, Lately, I've been having problems with my bookmarks:

• First, I found that I had somehow lost a large number of bookmark tags; it took me several days to restore them,
• Next, I found that I had lost a bunch of bookmark subfolders; the bookmarks (for the most part) are still listed under their tags.
• When I try searching for tags in Bookmarks Manager, the search yield no results
• When I try to restore my bookmarks from a previous date, I get an "unable to process file" message.
• When I try to open the profile folder through the debugging information page, I get a "file not found" message. After some searching, I found the profile folder not at "C:\Users\croge\AppData\Roaming\Mozilla\Firefox\Profiles\7csymh5k.default-release", but at "C:\Users\croge\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles", Something seems to have gone haywire--did I miss something, or is there an error somewhere?

I signed into one of my financial accounts and it said the sign in was with firefox windows 10. I have windows 11 on my computer. Is this a security issue? Fire fox says i am on the latest version

You sent me an email that says I have successfully created a password on "Windows 10" "I have Windows 11" ?? I need tech support because I don't know how to log into my account. Can I get a call at [edited phone# from public community support forum]. Name Paul Yoshida.

Hi,

On some websites (e.g. archlinux.org) most numbers are not rendered. See attached screenshots showing the same page on Firefox and on Konqueror.

In my font settings, I do allow pages to change fonts. Some pages (e.g. this one) do change the fonts and appear well. However, if I disable the feature, then they also break.

I'm using: firefox 145.0.2 (64-bit) archlinux plasma-desktop 6.5.3 wayland 1.24.0

Any idea?

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan
