I got a notice that Firefox (and Thunderbird) were updated this morning. Took me an HOUR to find out how to make the miniscule font in my inbox larger. So.. suddenly, new problem.

When I click the Firefox icon to launch the browser, and reopen my tabs, It opens for a millisecond, then closes faster than I can try to read if there is an error. When I click it AGAIN, all my tabs are GONE and I have to search for them manually, which is a royal pain.

Why is this happening? How can I stop it from happening? This is annoying as hell.

I'm having a problem with Win 11 that will likely require that I reinstall the OS. I decided to move most of the data in my User folder by right clicking and changing the drive from "C:" to "E:" in the Locations tab. Firefox was closed as a I did this, it worked fine, and then I restarted the PC. Upon opening Firefox none of the extensions are working and I'm not sure what to do.

In windows 10, I got used to opening a new window in FF and then a "tab" for the new window would open in the taskbar. I could then switch between windows by clicking on these tabs on the taskbar. In windows 11, I can click on the FF icon in the taskbar and open a new window, but a tab for that new window no longer appears on the taskbar. Instead of the previous tabs on the taskbar for each new/open window, there is nothing. I have tried the suggestion, found in another thread, to use about:config to change to false the setting browser.taskbar.previews.enable, but there was no difference. Does someone know another approach, or is this a windows 11 "feature"?

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

here's the video: https://youtu.be/qMY-38z_TC0

I don't know why, but since today firefox keeps reloading all my tabs I have open every couple of minutes. It happens on both my desktop and laptop and its getting annoying. I also disabled the auto refresh in config, along with clearing the cache. I uninstall the plugins that I installed last week, and still happens.

Firefox 117.0 Windows 10

When using Google search the screen locks and the cpu goes high. After approx 45 seconds the results are displayed. This does not happen using DuckDuckGo as the search engine. Google search is fine in Pale Moon and Edge. I have attached screen prints of the Firefox screen (the connection circle is constantly rotating during the 45 seconds) and a screen shot of Task Manager. This has only started happening since updating to 117 yesterday.

Thank you

I'm trying to connect to my Schneider XWPro Gateway for access to my solar inverter, and security policy on Firefox no longer't allows access. I can access using Safari by explicitly allowing access. Error from Firefox is as follows:

Secure Connection Failed

An error occurred during a connection to 192.168.1.120. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem

Your error message states there is a problem with a certificate conflict, however there is no apparent way to tell which certificate is causing the conflict, so there is nothing I can do about it. This is a new problem, I have been able to access this device in the past.

Any suggestions?

When i go to open a PDF file with Firefox, the text renders incorrectly (see image) for most PDF files, but not all (i'm not sure why. And this only happens with the Flatpak version of Firefox [1]. It doesn't happen with Firefox ESR (DEB version from my distribution) [2] and it doesn't happen if i view the same PDF file with pdf.js in a non-Firefox Flatpak app (GNOME Web) [3].

I've tried reinstalling and tried starting in troubleshoot mode, but neither seemed to fix the issue.

[1]:

• Name: Firefox
• Version: 117.0
• Distribution ID: mozilla-flatpak

[2]:

• Name: Firefox
• Version: 102.15.0esr
• Distribution ID: BLANK (preinstalled with Debian Linux 12)

[3]:

• Name: GNOME Web (Flatpak)
• Version: 44.6

I occasionally use a site (www.zoomcare.com) which does not work properly with Firefox (I've been using Microsoft Edge (Windows 10) to access it). The problem comes when I try to login. I enter my username and password, and that brings up a blank page that does not redirect to anything, so I'm stuck.

Just out of curiousity, I was looking through Advanced Settings, and found security.csp.enableNavigateTo. It has been set to false, but when I set it to true, I am able to successfully login (I still go to the blank page, but after a brief pause, I'm redirected to a logged-in page).

I'd like to know something about the security implications of enabling this property. Is it a bad idea? (Not knowing, I've set it back to false and will continue to use Edge for now).

Hello I have installed german Firefox Version 117.0 (Build-ID 20230824132758) on Windows 10.

The following ExtensionSettings policy works as expected. The addons ublock and TreeTabs are both installed automatically.

{

 "*": {
   "blocked_install_message": "My Message",
   "install_sources": ["https://addons.mozilla.org/"],
   "installation_mode": "blocked",
   "allowed_types": ["locale", "extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi",
   "default_area": "navbar"
 },
 "TreeTabs@jagiello.it": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"
 }

}

But I don't want TreeTabs to be installed automatically on all workstations. So I want to change installation_mode to allowed.

{

 "*": {
   "blocked_install_message": "My Message",
   "install_sources": ["https://addons.mozilla.org/"],
   "installation_mode": "blocked",
   "allowed_types": ["locale", "extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi",
   "default_area": "navbar"
 },
 "TreeTabs@jagiello.it": {
   "installation_mode": "allowed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"
 }

}

But with this setting I'm unable to install it manually from https://addons.mozilla.org/de/firefox/addon/tree-tabs/ The message "An unexpected error occurred during installation." and a popup with the "blocked_install_message" "My Message" is displayed.

The same error occurs without the line (and the comma) "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"

I don't know why this does not work. Please help. Thank you.

I'm having an issue with a particular text field. When entering any text into said text field, my CPU will shoot to 100% usage on some cores, hang for a bit and then print the text after a few seconds. I have an Intel 13900k @ 5.5ghz.

I can't provide a link to the text box as it's a WordPress CMS on my local machine. This issue does not present itself on the competitor browser.

A few troubleshooting steps I've taken:

• Re-install Firefox
• New profile
• Disable all extensions
• PC safemode + Firefox safe mode
• Tested dev/nightly/stable (I'm using BETA daily)
• Disabled accel

Hopefully I'm able to have an expert look at my profiler to help determine what the issue is. I'm not knowledgeable in this area unfortunately. https://share.firefox.dev/3s60ISV

Thank you.

Past experience. With just a few tabs open there was a "+" button at the right hand end of the tab bar for a new tab. When the number of tabs got too many (in my case 18) the "+" button was JOINED by a ">" button to be able to see tabs off the right hand end of the toolbar, but still use the new tab button.

Post update to the current version of Firefox, at the point the ">" button appears it is REPLACING the "+" button.

I know there are workarounds, but my "rut" is to use the "+" to get a new tab.

Is there any way of getting it back?

I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

Any ideas why I am seeing these strange rectangles on Google maps?

Confirmed not caused by an extension as I still see them in Private window and do not see them when using Brave.

They don't stay in the same geographical location when zooming in and out.

Using Firefox 117.0 (64 bit) with Windows 10 Pro 22H2, I have www.google.co.uk set as the home page. Whenever I use the homepage search box to enter a search term, Firefox stalls for about 10 seconds before showing the search results. Selecting any search results opens the relevant page straightaway. Subsequent new searches using either the search box at the top of the results page or the home page again also has the 10 second delay. Using the search box in the Menu Bar does not have this delay - the results are shown straightaway. This has been happening for the past two weeks or so and using the previous version of Firefox. I've been using Firefox for many years and have never had this problem. Chrome works fine. I've tried all the "solutions" found on the internet, refreshed Firefow, tried a new profile, troubleshoot mode, etc, without any change. Also, within the past 24 hours, I can no longer open www.screwfix.com - with www.screwfix.com in the address bar, I get a completely white page without any error message. Screwfix opens fine with Chrome on this machine and with Firefox on Android tablet and phone. Please can you help with this. I'm in the UK. Thanks
