How can I disable COMPLETELY the tab previews a/when I hover over a tab, and b/ when moving tabs (using left click and hold)? I've tried the various options listed in other questions on the support forum: nglayout.enable_drag_image = false browser.tabs.hoverPreview.enabled = false browser.tabs.hoverPreview.showThumbnails = false

Along with unticking "Show tab previews in the Windows taskbar" in settings.

None of these works to completely disable the previews.

Is my only option to reinstall an older version of Firefox... again?

Firefox 133.0b6 (64-bit) Windows 10 Pro

How the hell do I remove this crappy sidebar!?!?! Your suggestion of tapping the cog and clicking on sidebar button DOESN'T WORK! REMOVE IT! It is annoying, terrible! Why would you mess with something that didn't need to be fixed ? What are you, Jaguar? Remove it now, actually do something and fix it.

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.

Using Firefox 131.0.3 (64-bit)

I have payment methods saved. On payment sites, I click on the CC# input box, and I am given the option to use one of my saved payments. I mouse-over payment choice, and it populates the input boxes with the correct information, however once I actually click the payment method, the payment method and all the input boxes are cleared of all contents. I am therefore forced to enter payment information each and every time I want to use it. The Fill Payment method isn't working.

I have reentered and verified the saved payment method several times.

I recently added an entry to my hosts file but Firefox seems to ignore it. I'm using v. 128.5.1esr, fully updated. I've tried a lot of the advice online and none of it seems to work. Here's what I've tried:

disabled "Enable DNS over HTTPS Cleared the DNS Cache changed "Use system proxy settings" to "No proxy". tried troubleshooting mode set network.trr.exclude-etc-hosts to true changed browser.fixup.dns_first_for_single_words to true changed network.dns.offline-local to false restarted FF, rebooted computer

It doesn't work in Chrome either, which makes me wonder if it's a Windows 10 issue. Any suggestions?

Please explain in simple terms (I am not an IT wizz) how I can stop the continual popups in Firefox 128 and Thunderbird 78 on a Windows 11 OS saying “Update Available” with a Download button very easily activated by mistake.

Each time I click Dismiss, a new popup appears either immediately or very soon. The popup blocks a significant area of the screen and will not move.

I already have Update Settings on “Check for updates but let you choose to install them”. There is no option to “Do not check for updates” on these versions of Firefox and Thunderbird. I already have Windows 11 Notification Settings on “Do not disturb” and all Firefox notifications to Off.

I have found the Mozilla Support article “Customising Firefox using Group Policy” at  https://mzl.la/3bLnw2J but I do not understand it and the device I am using is not part of a group installation setup. 

There is a Step by Step guide “How to stop Firefox update notifications” on Youtube at https://www.youtube.com/watch?v=nD-oXxrCCRs . This is clear to follow if I pause it frequently to absorb each step carefully. Is this safe for me to try given that I am very inexperienced in using the command line and accessing registry etc?

The Thunderbird popups have only recently started up and I would value advice on how to stop these safely too. I need this version of Thunderbird at present for particular reasons related to gmail so it is important I do not accidentally activate a download on that.

Firefox binds to absolute add-on paths, why?

I tried to create a default Windows profile with pre-configured app settings, including FF. I created a temporary user, logged in, installed FF and configured it, also installed some add-ons (first of all, ublock origin). Then I logged out, logged as an administrator and moved the temporary user profile to the default profile location (c:\Users\Temp -> c:\Users\Default), and then reset its NTFS permissions. This almost always works for all applications, including Google Chrome. I created a new user and logged in, opened FF. The settings were applied, but the extensions did NOT work, and even the buttons on the toolbar looked like empty squares. At the same time, the add-ons were present in the list of add-ons in settings, although without icons. It helped to turn off and turn on all the add-ons one by one, manually.

After some research, I realized that FF binds its settings to absolute paths to add-on files (*.xpi), specifically in the $profile/extensions.json and $profile/addonStartup.json.lz4 files. Google Chrome, for example, doesn't do anything simular, like the vast majority of applications. Removing these files from the profile will cause all add-ons to be "reinstalled" on first launch and set to a disabled status.

An easier way to reproduce the problem: 1. Run firefox -profile d:\temp\profile1 2. Install some extensions. 3. Rename profile1 folder to profile2. 4. Run firefox -profile d:\temp\profile2 5. Got it!

For what purposes does firefox bind to absolute add-on paths, and how can this problem be solved? P.S. I know about portable firefox from PortableApps.com, but I don't want to use a third-party loader for my tasks.

Firefox inhibits power management, causing the screensaver to not activate. This happens when I am not running a video. It happens if I open a website that has video but I do not run the video. If I turn off Firefox the screensaver works. Screensaver is set to activate at 5 minutes. Power Management is set to turn off screen when inactive for 7 minutes.

I'm visually impaired and had originally used a CSS code to fix this problem, but that was a couple of years ago. I just upgraded to 131.0.3 (64 bit) and evidently, that wiped out all my CSS changes. I tried to use the about:config code to change it, but it no longer works. I managed to increase the icon size a little by changing the density to normal, then back to compact. Even on normal, it was all too small.

I don't want to use another profile, because every time I do, I lose so much that it takes me hours to reinstall it all.

Is there an easier way to do this? I've tried a couple of things suggested online, but they were old settings suggestions, and they no longer work either.

ALSO, I now have to use F11 full screen to be able to perform anything on the toolbars. Before this update, I could just move my cursor up to bring the toolbars down, and use the back arrow or refresh easily. Now, the toolbars immediately go back up and I have to use F11 to do anything. How do I fix this?

TIA for any help you can give me.
