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

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.

This is the message I get when I try to access my Bookmarks: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I have already tried to find out from Microsoft if their latest reinstallation of Office Professional could have caused the problem. They say they have nothing to do with Firefox. How can I get my Bookmarks and History back?

I recently tried to connect to two different meeting sites. Both times I got a pop-up noting (correctly) that camera and microphone are blocked. I'm able to click to enable the microphone but I never get the option to enable the camera.

I tried going to Settings>Security&Privacy>Camera but that only allows me to remove previously-enabled websites.

Clicking on the settings button in the address bar shows audio and recording settings but no camera.

What am I doing wrong?

Fedora 42 Firefox 145.0

Tonight I was roaming around my Firefox settings looking at something else, when I noticed this AI piece pre-checked. Why is FIREFOX, who is supposed to be for privacy and security, authorizing an update that automatically choose AI? Not cool Mozilla. Not Cool. Anyone else have this? and yes, I've already fixed it ;-)

Recently several sites, including Zoom.us and Genesis.com, no longer work in Firefox on my PC running Windows 11. For example, when I log into Zoom spinning wheel indicating the system is working keeps spinning and never lets me enter my password. Yet if I use Edge everything works as it should. I really want to be able to keep using Firefox as my default browser.

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

bold text how do i move bookmarks along the bookmarks tab

I have just bought a new computer. Got firefox working and I have bookmarks on the bookmarks tab below the search box.

I used to be able to move bookmark tabs along it and it was my main organisational method.

OR I would drag a url down from the search bar to put it on the bookmark tab below

neither of these methods work any longer and it is a real problem.

I cannot think of a worst thing you could have done.

Help how do i move a bookmark along the bookmark tab, or move a url to the bookmark tab, or move those bookmarks which I can't see to the visible section below the search bar

Unfortunately the latest release has broken the ability to support the NordPass extension. I also have WaterFox as a backup based on historical usage challenges, and sure enough it supports NordPass with no issues.

The issue is when a user completes the Account login to Nord itself, then enters their master password for NordPass via the browser. It then gets lost, presenting the animated circle as if it is attempting to process the next step, and it fails to exit that state.

I am getting the following message on a couple of different website pages today. "Please unblock challenges.cloudflare.com to proceed." I don't know what this means! What do I do to unblock/fix this, please?

Thanks, Paul

I would like to further customize my new tab page.

Specifically, I'd like to get rid of the firefox logo at the top, and I'd like to increase the number of columns of shortcuts per row from 8 to lets say 14, while decreasing the spacing between each icon by about half.

I've already followed [tutorial] from y'all on how to increase the number of rows, and another tutorial that had me fiddle with the browser.newtabpage.activity-stream.topSitesRows setting directly in my about config. I have enough rows I want more columns and less space between them.

Find attached the current state of my new tab page, with my particular shortcuts redacted, and the number of additional shortcuts I could fit on the page without adjusting the gabs between them or resorting to a scroll bar. I'm missing out on at least 44 short cuts due to the default constraints, which I've been unable to find working overrides for. Depending on how cut-throat I get with my thin-margins, I could potentially be missing out on up to 80.

I tried following the near identical instructions from both this stack exchange and this tutorialpedia article, to try and get at the problem by modifying my about page's CSS; but I was unable to change part of the page's appearance. Not even the background or text color.

Is the information in these out-dated (the stack-exchange is 7 years old) or otherwise inaccurate; or is there perhaps a setting in firefox which is interferring with these tutorials' solution method.

I have already tried resetting firefox with extensions disabled to check if any of my extensions are causing the problem to no discernable affect.

I've received a handful of emails from the Social Security Administration regarding the 2026 cost-of-living adjustment (COLA). Each time I click on the provided sign-in button, Firefox fails to connect. I am attaching a screenshot of the message it gives me instead. Today, on a whim, I tried to sign in using Chrome, and it worked fine. What is wrong with Firefox?

I have really liked using the "refresh" button with my Firefox browser. The "refresh" button has disappeared from one of my two Dell PC's (I use Windows Eleven, and my Dell PC's have solid state drive). I know there are two other "help" buttons ("troubleshoot mode" and "clear startup cache"). The "refresh" button has really helped me to keep my Firefox browser working properly with my two Dell PC's. Thank you for any comments you might have about this.

This started after the recent update. Any time i open more than 1 firefox window or try to move my window to a different monitor, the Menu Bar pops up and left click will be stuck only making the bar appear/disappear. I just have to close the second window because it becomes immediately unusable. I have the ui setting set to false but it still freezes new windows and doest let me click or type on anything. I've uninstalled and reinstalled, ran troubleshoot mode, got rid of extensions, reset my computer. I'm at a loss. Any help would be great

I think that this recent update removed all of my tabs and tab windows, it has done this before and I don't understand why, I have the old update session file still (The 11/11/2025 One) and I tried to use that one to bring the tabs back by putting the file in the sessionstore-backup folder with no other file in it, but they didn't come back. I am genuinely confused as to why it doesn't work, I have renamed and deleted sessionstore.jsonzl4 files but it still comes up as a new session.
