Hello,

I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main

Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.

If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:

// My new tab
try {
  const ff = {};
  ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
  ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}

Note that the file must start with a comment

Adapting the "/path/to/my/index.html" to your needs.

Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.

I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

How do I stop Firefox from opening Finder in a new window? I don't want to have to go back and forth between windows. The same thing happens when I open a PDF. Thanks.

Dear and respected ,

As you can see from the screenshot i provided and as you can read from subject of this very annoying issue Firefox new 130 update has changed my URL bar and now stuff are missing to the point that links to Outlook and some other stuff that were in address bar URL because i wanted them there and now they place has been taken by namely foxovizija.blogspot.com and watchonlyfoolsandhorses.com and ajax.nl/shop just because i watched few episodes of fools and horses on that link same goes for foxovizija and browsed some items in ajax fan shop! I WANT DOES LINK GONE FROM MY URL so i can put links that i want to be in there and FF 130 address bar being populated by only the links i want to be there and stay that way! and one more thing i want to get rid of that ugly search with google thing because i don't even use google,further more once all of a sudden in FF 130 MY BROWSER IS MANAGED BY MY ORGANIZATION ? That was never there before this update ,so with all that has been said and screenshot as proof i beg you and plea on your kindness and knowledge to give me guidance how to fix this URL thing first,then how to remove THIS BROWSER IS MANAGED BY YOUR ORGANIZATION and last but not least how to block further FF updates because every new update is worse then the next and just keep pushing the whole browser down the drain ! Thank you very much for your kind,unselfish,professional and knowledgeable support in fixing up this mess

I recently updated my MacBook Pro to the latest MacOS (Sequoia). Though I didn't notice it immediately, today when I opened Firefox, all text is displayed in a foreign character set. It is pervasive - I've tried to use several tutorials to reset the language and all settings to default, but so far nothing has worked. I've uninstalled Firefox using AppCleaner (which gets any leftover files in OS folders, as well as the app itself), but a clean install results in the same issue. I've disabled all add-ons and reset all settings to default as near as I can tell. The only time the browser displays properly is when it's in Safe Mode. I'm not sure if this is related to the OS update, but I can't seem to identify any other recent change that could have the potential to cause this problem. Any suggestions would be greatly appreciated.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

After briefly succumbing to the ToS hysteria, I decided to switch to Librewolf. It took a while, but I got logged into sync, set up my extensions and copied over my cookie exceptions and custom CSS.

Some of the data that came over from Firefox sync seemed very wrong or out of date, most notably the settings for container tabs. No big deal I thought. I'll just manually edit the discrepancies. Once I had everything set up the way I like it, I looked up a guide on how to sync my current configuration with the cloud and followed the steps.

Phew. Time to watch some YouTube to relax. Problem is that when I finished a video and tried to watch another video, I was logged out and my site settings had reverted to default. I figured the cookie settings were wrong, so I went to the settings page and saw the behaviour outlined in the video I posted.

I've been trying to get this working for over a day now. I've tried resetting Firefox, creating new profiles and doing a clean re-install using "Geek Uninstaller" to make sure everything is removed first. I've tried 3 different forks of Firefox and all 3 of them do the same thing. After I re-install everything, I open the browser and the first thing I do is go to the settings but it's still doing the thing I showed in the video.

The fact that the data on my Firefox Sync is so old has me wondering. Why won't the cloud data update itself anymore? Based on the state of my containers, the Sync data is more than a year out of date. Could there be something wrong with that data that broke my browser when it downloaded?

I'm going to try and get hold of another computer later and try syncing to that to see if it breaks that browser too. I'll update this post when I know more.

Thanks for reading all this.

P.S. I'm typing this using Edge because my Firefox is so badly broken.

Web-Browser Firefox 128.7esr The time in the browser and the local time are different. Difference in time zones three hours. Checked on the website https://2ip.io/ How to configure Firefox so that there is no difference?

I am a bit confused about how to keep updating FF on my Windows 7 PC, given that after March my current version (115.17.0esr) may not work as intended. Until now I've always updated manually by downloading a small 343KB installer file that updated FF without changing any of my settings, logins and bookmarks. Hoping to simplify updating, today I set updates to "Automatically install updates (recommended)" with sub-option "When Firefox is not running". But just now a FF notification informed me it was unable to update automatically and provided a link to https://www.mozilla.org/en-GB/firefox/enterprise/?reason=manual-update. From the dropdown there I chose "Windows 64-bit" > "Firefox Extended Support Release (ESR)". The download is a 64MB file.

Since this seems to be a new installation and not a simple update, can I be sure it won't overwrite my current version and leave me without settings, logins and bookmarks?

Please how do I stop these floating windows above the tabs in Firefox 131.0? They mostly cover up the tabs and make it difficult to impossible to open or close tabs. The floating window only half shows up above he tab. This is just insane and makes using Firefox almost to much to deal with. Every time I get near a tab the floating window appears and tells me what the tab already tells me. Come on this is GARBAGE!

H E L P !!!! PLEASE....

I have run across threads with similar questions in both mozilla support and reddit, but as they are old and archived I cannot add additional info or request clarification, so here is (yet another) new one- I understand you can go into manage data in settings to delete what you want, however in mine it only shows a handful of most recent (opened today or currently open) since my settings clears history and deletes cookies upon exiting ff.

Cookies and Site Data section shows only 40.7mb of data is stored and in Manage Data only shows 8 sites... Clear Data area, with only these two boxes selected (attached) and 'everything' (time) still only around 50mb. My storage/default folder has 1005 folders and the data is over 1.5gb; I would like to manually delete all of this and as others have tried to ask, am wondering if this is ok to manually select them and delete in windows, or using windows %appdata%(?) and if so, will the sync feature (if I just clicked 'sync now') still retain all my bookmarks when I relaunch ff? Not concerned about any browsing/form history or passwords, only bookmarks.

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

I've never had sponsored shortcuts and suddenly today I've got them. I've attempted the disable the "sponsored shortcuts" on my desktop however its greyed out.

Starting state - Shortcuts selected, sponsored selected and grey Procedure: 1.) Deselect shortcuts, select shortcuts, sponsored becomes cyan 2.) Click sponsored, it becomes grey again 3.) Deselect shortcuts, select shortcuts, sponsored becomes cyan (again) 4.) Click sponsored, it appears deselected 5.) Hit refresh and it returns to starting state

I do not edit my GPO or registry, settings are not controlled by an organization, I am not confusing sponsored shortcuts with pinned search engines.

I've been using Firefox for a few months now to follow online training courses or videos on the conversation papillon (www.conversationpapillon.com) and conversation santé (www.conversationsante.com) websites. For a few weeks now, the videos are no longer accessible on the pages of these two sites. The window of the video is empty. However, if I try the same link in Google Chrome, it works fine. I've contacted the publishers of these two sites, who tell me that nothing has changed on their sites in recent weeks. He advised me to contact you to find out more. Can you help me? I prefer to use Firefox, which protects my privacy better. Thanks in advance. Regards, Jean-Pierre R.

I have two computers. Both sign into the same Firefox account. Both instances of Firefox are the same version (134.0.1 64-bit).

On my main computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the first image (firefox_2025-01-19_17-42-57.png)

On the other computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the second image (firefox_2025-01-19_17-43-57.png)

How to I get both instances of Firefox to do the same thing when creating a new tab, i.e. organize the recommendations like the second image?
