I am using version 147.0.1 (don't know when last update) For the last 1.5 hrs I have been trying to restore the extensions icons as well as other, to the tool bar. when I close "customize" after putting them there they disappear, as does the "puzzle" piece I put up there. What is going on? I have read numerous articles on how to fix this to no avail. Only one character will stay to the right of the added search bar.

Hi,

I am not a tech savy person. My firefox crashed on my laptop. Now all my book marks are gone. But the book marks are there on my iPhone. Can somebody please please help me to restore?

Where are my shortcut tiles? I used CCleaner and they all disappeared and I can't get them back even though I make sure they were on and have 2 rows selected and restarted my computer since. This happened last week and still no sign of them. See pic for reference.

need to replace bookmarks on server not merge them, w/bookmarks on locale device

currently when i log in it merges what is on server w/ what i just reworked and getting rid of multiples ... will have to do this again as i clean even more so need ot know how to accomplish exchange not merger

When printing puzzles from USA Today on my Canon Maxify, the crossword puzzle and the sudoku both show up as two pages, when they are only one each. If I don't change the setting from All to Current each time, it will print a blank page with each puzzle. This just started happening within the last month or two, but I have had Firefox/Duck Duck Go for many years. If I switch my browser and search engine to Google, which I hate, it shows and prints each puzzle properly. I don't know if it's the browser or the search engine, but it is a problem that I didn't have until recently. The print box is completely different from Firefox/Duck Duck Go to Google, so if it is Duck Duck Go that sets the printing box, I need to contact them. Firefox version 147.0 on Windows 10 on Lenovo laptop. Thanks in advance to anyone with a solution.

I have two machines running Windows 10 and Firefox 64 bit (synchronised and up-to-date). I recently noticed that the desktop is missing several Firefox bookmark folders, which contain hundreds of bookmarks.

How do I get the desktop fully synchronised with the laptop? Do I use backup? If I am to use backup, how do I see what is in backup, so that I know it is backimg up correctly? Do I reinstall the Firefox and import from backup?

I am getting the following error message when using Firefox. 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 cannot see my bookmarks or add new ones. I followed the directions in articles about this problem and they did not. help. I decided to uninstall Firefox and l re-installed it from scratch and i still get the same error message.

It seems to me that recovery from backup only allows one to recover ALL bookmarks. But maybe one wants to recover only one folder, or only a few folders. Can that be done? If so, how?

Hi, The site https://fortunenette.fr/ does not display properly in Firefox on my MacBook Pro running macOS 15.7.3 (build 24G419).

The header and navigation load fine, but the biography articles and the richest people table stay blank or show only placeholders. In the Firefox Console I see these errors: Uncaught TypeError reading 'length' of undefined, mixed content blocks for HTTP resources on an HTTPS page, and several CSP violations for inline scripts.

I already cleared cache and cookies, disabled all extensions, tried Private Browsing, turned off Enhanced Tracking Protection, and changed some about:config settings like strict transport security. Nothing helped.

The site loads perfectly in Safari and Chrome on the same Mac. It happens in Firefox 147.0 and the 148.0b2 beta too.

It seems like a Gecko-specific JavaScript or rendering problem. Has anyone else run into this? Any workaround without switching browsers?

On Chrome, web push notifications show the full origin (e.g. pl2.forgeofempires.com), but on Firefox only the notification text is visible, without the website address. Is this a Firefox limitation by design, or is there any way to enable showing the full origin in notifications?

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

The first time i'm installing Firefox it quickly made me fall in love with this browser and wanted to fully migrate from Chrome to Firefox, it's more lightweight, has more customization, fully private & secure. But there is only one thing that made me just almost migrate to Firefox, or just 99% complete transitioning to Firefox, and that is me unable downloading. Yes, thats it and it's pretty annoying. I just able downloading pictures, but not when i'm downloading an apps or software like Discord for example. PLEASE HELP ME, MY LAPTOP (X240) IS VERY OLD AND I NEED EVERY PERFORMANCE ON MY LAPTOP FOR WORKSTATION PLUS WITH THIS RAM PRICES (ykwim). Tomorrow i'm planning to switch to Linux (Mint MATE) and i have to do dual-boot just incase there is some software i'm unable to use at Linux. So please, help me. Give each step with no technical explanation, and use beginner languange so i'm easier to understand.

Hi, I’ve been experiencing slow startup times in Firefox, especially when I have my Time calculator web app open. The browser takes longer to load and sometimes becomes unresponsive.

I’ve tried disabling extensions and changing my home page, but the issue persists. Are there any specific settings or troubleshooting steps in Firefox that can help improve performance when using online calculators like this?

Any guidance or tips would be greatly appreciated. Thanks!

My bookmarks disappeared and I do not know why.

I have tried to restore bookmarks following the directives obtained online. Somehow this has not been successful, and this remains a giant puzzle to me.

I can see the bookmarks in Library, but I have not been successful in figuring how to transfer that listing to the Bookmarks tab at the left-sided top of the frame of the browser.

Thank you.

I’m running into a limitation with Firefox profiles involving the original Profile Manager (about:profiles) and the new Profiles menu in the toolbar.

I previously created multiple profiles using the original Profile Manager (about:profiles), for example profiles A, B, and C. These profiles still function normally and can be launched through about:profiles, but they do not appear in the new Profiles menu in the toolbar.

I also tried using the “Copy this profile” option available from the new Profiles menu. This made it clear that the feature does not work with profiles created via about:profiles. For example, when I open profile A, I expected that I could use “Copy this profile” to copy profile A into an existing profile like profile B (which was also created using about:profiles). However, this is not possible. Profiles A, B, and C remain isolated from the new Profiles menu and cannot be accessed, copied, or managed through it.

At the moment, profiles created with the original Profile Manager (about:profiles) can only be accessed through that manager and cannot be transferred into the new Profiles menu in the toolbar.

Is there an official fix or a workaround that achieves the same result—specifically, transferring or integrating all existing profiles created with the original Profile Manager (about:profiles) into the new Profiles menu accessible from the Firefox toolbar?
