I've deleted the user and prefs.js data etc. but all the dumb changes I made before switching users just make their way back no matter how many new profiles I create. I have standard Firefox, with Nightly and Private versions installed. Win 11 25H2 whatever its called now.. please help.

These are technically two separate issues, but both pertain to functionality of the mouse and keyboard. Whenever I right click to bring up the menu, the options (despite being functional) do not appear in the menu proper. Instead there are just empty buttons. In addition, certain hotkeys aren't working at all. Ctrl+C and Ctrl+V to copy paste are doing fine, but Ctrl-T and Ctrl-W to open and close tabs respectively do nothing. Neither of these issues were happening yesterday.

Over the past few updates, I’ve noticed an issue with Firefox where it no longer restores my previous session when reopening the browser.

I normally keep four tabs pinned and about five additional tabs open for browsing and work. In the past, I could simply click the X to close Firefox, and when I reopened it, all my tabs that are pinned and unpinned would automatically come back. Recently, this stopped happening. Now, if I close Firefox, it opens with a fresh window instead of restoring my previous tabs.

I’ve already checked the setting under General/Startup, and Open previous windows and tabs is enabled. Because of this issue, I avoid closing Firefox entirely, since rebuilding all my tabs each time has become a hassle.

Is there a way to fix this? Any suggestions would be appreciated.

Thanks :)

Recently I am unable to pull up saved passwords when logging on to sites I use regularly. I can go to Settings, Privacy & Security & check the box "Ask to Save Passwords". The saved passwords then stay on even if I close & reopen Firefox. All is then well until the next time I restart the PC. Then it defaults back to an unchecked box. How can I set the PC so that the "Ask to Save" button stays on? Upgraded to Windows 11 about 1 month back. Thanks.

zen_browser has this feature which I use multiple times per day every day: keyboard shortcut ´shift+cmd+c`to copy current URL to clipboard.

This is such a useful feature. It helps me save time and speed up my workflows a lot, so much that it's absence in Firefox is preventing me from going back to Firefox.

The feature was implemented in v1.6b back in early 2025 in zen_browser.

This might be quite "old man yells at cloud" of me, but oh my god I am so fed up of everything putting AI in as a "feature" for no reason.

1) No one asked for this. 2) It is bad at doing whatever it is designed to do. (It's not helpful, it's not even neutrally unhelpful, it's ANTI-HELPFUL.) 3) It is always on by default, or worse, impossible to turn off.

At the very least AI features need to be off by default, because it's rubbish.

Firefox is meant to be a bastion of sanity and safety in a world of exploitative techbros trying to steal our data and trick us into making money for them. So-called "AI" goes against this. Please, Firefox, be better.

As of 20th Nov 2025, here's how to turn off AI features. Go into about:config and set all of these to false (yes, you’ll have to copy and paste them one by one):

  • browser.ml.enable
  • browser.ml.chat.enabled
  • browser.ml.chat.menu
  • browser.ml.chat.page
  • browser.ml.chat.page.footerBadge
  • browser.ml.chat.page.menuBadge
  • browser.ml.linkPreview.enabled
  • browser.ml.pageAssist.enabled
  • browser.tabs.groups.smart.enabled
  • browser.tabs.groups.smart.userEnabled
  • extensions.ml.enabled
  • browser.search.visualSearch.featureGate

in addition to nuking AI, it’ll also speed up your browsing

In the year 2024, firefox still does not allow a simple way to set any URL you would like as the new tab url (without an extension).

Users were previously able to use extensions like NewTab override to have a relatively seamless experience changing their new tab page. However after certain changes, these said extensions can no longer set your new tab page to a local file, and can also no longer clear and focus the address bar.

I am simply requesting a feature within firefox to set a custom new tab page, without having to create any external configs, or without using any extensions. This basic feature has been available in chromium browsers for years, and firefox already includes a feature just like this for the "Homepage and new windows" setting, where it allows you to input a custom URL to a local file or site to put it as your homepage. However, this same setting for some odd reason does not exist for the "new tabs" option. Why is this?

As of now, I've had to use a manual override along the lines of this:

``` // shenanigans for setting a different new tab page const { classes: Cc, interfaces: Ci, utils: Cu } = Components; const { AboutNewTab } = Cu.import("resource:///modules/AboutNewTab.jsm", {}); // path to new tab can be a url or file const newTabURL = "file:///home/faaris/.local/packages/startpage/fazzi/index.html"; // set the new tab URL AboutNewTab.newTabURL = newTabURL; ```

this should not be needed. Having to modify files in system protected folders should not be needed for such a simple option.

hi, spellchecking works fine when using Firefox in Linux, but not in Windows 11. For instance, I can enter comments and replies to magazine articles while using Linux and they're spellchecked as I go by highlighting misspelled words etc, but if I'm in Windows 11 and on the same comments section, although my Firefox settings are the same the spellcheck doesn't happen. Can anyone please tell me what's up with that?

On a brand new profile for Firefox without configuration of any kind I get an AI chatbot in the sidebar and AI tabs suggestions.

Why?

Is Mozilla looking to destroy decades of good will?

Anything like this should be something you have to opt-in to see, not try and opt-out of.

If privacy is a true concern then any of that stuff should be an extension, and not something on by default.

I really don't understand why Mozilla is doing this.

However, I wanted to add hone button and a few other mods to the toolbar but when I started customize the toolbar from menu pic the customization page would not work, it appeared and seemed OK but when I dragged and dropped anything it would not work. I could pickup items but they would not place in toolbar and just snapped back to the pallet. I tried several different ways to enter the customization area but it was always non-functional.

Hello,

I wanted to ask if there’s a way to configure the setting for "Store data in permanent storage" (or "Daten im dauerhaften Speicher speichern" in German) to always block/disable ALWAYS via Group Policy or Registry Editor.

As we are a small company, I would like to apply this setting for all Active Directory users.

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.
