I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

For the past few months every restart of Firefox disables LastPass. I did NOT have this problem previously. The version of LastPass is current (no updates found). I can go to Add-ons and the toggle is set to "on" but the icon in the menu bar is black. If I click the toggle off, then back on, LastPass comes on just fine. Why is Firefox disabling something that Add-ons says is loaded? VERY strange. Does NOT happen in Chrome. Thanks for any assistance. PITB!!!

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

In previous versions of FFx, toggling to Reader view used the same font I'd chosen in Settings / wherever. Now it's something else, in boldface with no distinctions made in original view (italics, not italics, etc). & there doesn't seem to be any way I can control fonts in Reader.

Any suggestions? In plain English, please, I am NOT a programmer or computer professional, just a regular human trying to use this new version that seems to have broken everything I liked about FFx.

Firefox has started making a piercing high-pitched screech when the "save image" and "file update" panels appear. This is a confirmation or alert sound I suppose. It occurs when saving an image from a right-click menu and when downloading a file. Formerly Firefox used the system default sound for this, and that sound is still working in other programs for similar operations.

How can I fix this? Or alternatively how can I disable the sound during such operations in Firefox (or alternatively system-wide)?

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!

Good day, has anybody an idea if and what addon could manage for me redefinition of mouse behaviour. Particularly in my case I want to use middle (wheel) button single click over any text input to perform clipboard paste (but everywhere else the button behaves normally). I had this feature integrated into mouse gestures add on which is no more compatible.

The spell checker isn't working for me. I've found old answers to this:

"You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu. At least one dictionary should be installed and have a check mark to indicate that it is selected.

   open the "Add Dictionaries" link to install a dictionary if you do not have one. 

The spelling checker is enabled if [X] "Check Spelling" in the right-click context menu has a checkmark.

You can enable or disable spell checking globally:

   Options/Preferences -> General: Language and Appearance: "Check your spelling as you type" 

You can look here for dictionaries:

   https://addons.mozilla.org/firefox/language-tools/ 

Note that for spell check you need a dictionary. A language pack provides string translations for the user interface.

   https://support.mozilla.org/en-US/kb/use-firefox-interface-other-languages-language-pack 

You can check the layout.spellcheckDefault pref on the about:config page.

   http://kb.mozillazine.org/layout.spellcheckDefault "'

But I don't understand what most of this means!

I don't find 'language' because I don't know where to find a "text box containing more than one line" I'd have thought this was one, but the option does not come up here when I right click.

I realise this is probably me being dense, but can someone help in simple terms, please? Thanks.

Title,

The option to switch languages is also not present in the right click menu (see attached image)

I'm really unsure how to figure this out so any advice would be greatly appreciated.

Thank you for your time.

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

A while back the behavior of the ctrl+shift+t shortcut changed from reopening tab in the current window to reopening tab in the current window or reopening last closed window which for me and a lot of other people too made it worse. There's been a thread https://support.mozilla.org/en-US/questions/1421356 but it's been archived without a real solution. Is there now a way like a about:config toggle to bring back the old functionality? I really miss the old behavior.

Hello, recently I've been having issues where if misclick anywhere on the title bar (even in the small space between bookmarks) firefox will minimize/restore when I didn't want it too. How do I disable this in about:config?

Right now i love my HDR content in most scenarios, except on a few sites where its just bad. Is it possible to be able to block it on certain sites where you dont want to apply it?

For many years I have used the ability to set shortcuts to website on the Firefox home tab, using the method given at: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_pin-unpin-or-remove-a-shortcut.

However, today, when I try to edit a shortcut link, I do not get the 3 dots menu by right clicking on a shortcut tile.

Is this a recent change, a bug, an issue with my installation (which has been stable for many years)?

How can I get back the functionality back?

I am using Firefox 127.0 (64 bit) on Windows (Windows 11, all up to date).

Firefox 126.0.1 displays a very long name of a container completely in the URL bar.

Firefox 127.0 truncates container names

AWS long account and role names make keeping the long name very convenient (works with the 'AWS SSO Containers' Add-On

Hi, got a problem for the last several days - on each visited site Firefox (my guess) is launching a pop up about add-ons for Ad Blocks tham I am using were updated with official national filters for Polish market.

This is super annoying and the pop-up jumps on almost every new site bieng visited (it is visible for ca. 5 seconds). Is there any way to stop it? How can I dissable this feature?

Thanks, r.

Settings > Home > New Windows and Tabs > Homepage and new windows

This setting got reset on me last night. Using 127.0.2.

So, I set it to custom, add in a URL, close the settings, re-open the settings and see it is set.

I close my non-pinned tabs and then close the browser.

Upon opening the browser, I am greeted with an empty tab and the Setting has reverted to "Blank Page".
