Howdy! Here are the details noted in my question.

My browser is not working as it should. Several sites do not work anymore and the browser keeps crashing. I'd like to refresh the browser, but the button is missing. I tried going to troubleshooting mode, but the button is not there either.

Not sure if uninstalling would do the same thing? Just not sure what is the best way to refresh. Thanks for any help!

Hello,

I'm a bit out of ideas how I can get Firefox to display the correct characters. For reference: https://learnjapanese.moe/font/

Windows: I only have german and japanese locale installed, i even changed in intl.cpl the language to japanese. I have installed the japanese language pack / fonts and it's showing correctly in any windows editor.

Firefox: Second language set to japanese, disabled all addons, tried it on private mode to no success.

Any ideas how I get the characters to display?

Edit: I made it work by changing in about:config the font.cjk_pref_fallback_order-string to have ja as first.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

The release notes for Firefox version 140.0.1 indicate the extension button can can now be removed from the toolbar.the noes say:

"Firefox Extensions: Customize your toolbar with the option to remove the extensions shortcut, giving you more control over your browser. When the button is hidden, you can access the extensions panel again at any time from the Firefox menu by clicking the Extensions menu item."

I still cannot drag the button down and out of sight by customising the toolbar.

Suggestions welcome.

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 searched how to disable any random new AI features Firefox was about to cram into the browser.

I was served this support page that says I can "Block new and current AI features (single switch)"

Simply, the described feature to disable AI features isn't in the settings. I've look and tried searching for "Block AI enhancements" & "AI controls" but no luck.

Please tell me they haven't given the writing of support pages to some shitty LLM.

In other browsers when I add extensions, I can open an extension panel, or got the the browsers installed extensions section, and edit open up my extension setting pages, and edit them. For example uBlock Origin, but there are others. It doesn't seem possible to do such a thing with Firefox. Is that on purpose or is something wrong?

Windows 10, current with latest update. My release of Firefox, after all latest updates, does not show/list any TOOLBARS on the left side of the page. They are gone. I can't find anyway to get that list back. Import from MS/EDGE does not work. I see some TOOL Icons across the top of the page, I repeat............. SOME Tool Icons, not many. Tried to query for help in Mozilla posing that same question. ZILCH of any helpful reply. this is what is answered.......................

To list the toolbars in Firefox, you can: 1. Click the menu button • • Click More tools • • Select Customize toolbar • • Click the Toolbars dropdown menu at the bottom of the screen • • Choose the toolbars you want to display • • Click Done

To display your bookmarks in Firefox, you can use the Bookmarks Toolbar, the Firefox Sidebar, or the Menu bar Bookmarks menu: • Bookmarks Toolbar You can show or hide the Bookmarks Toolbar using the View menu, the keyboard shortcut Ctrl + Shift + B, or by right-clicking on the Tab bar: 1. Click the View menu at the top of the screen • • Go down to Toolbars • • Select Bookmarks Toolbar • • Choose from the following settings: • Always Show: Shows the toolbar on all pages • • Never Show: Hides the toolbar on all pages • • Only Show on New Tab: Shows the toolbar only on the New Tab page 1. • o • Firefox Sidebar You can toggle the Sidebar on and off by clicking the Sidebar button and selecting the option you want to load. • • Menu bar Bookmarks menu You can access your bookmarks from the Menu bar Bookmarks menu if the Menu bar is enabled. To show the Menu bar, you can: 1. Click the menu button • • Click More Tools • • Choose Customize Toolbar • • Click Toolbars at the bottom of the window • • Click Menu Bar • • Click Done to save your changes

Nothing works. There is an attached screen image of the Mozilla Browser Page I see. Thanks for listening.

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.

Hello, I have just upgraded to windows 11. On firefox I used to be able to right mouse click on the firefox icon in the taskbar to select my saved saved (Pinned) websites. In the past with Windows 10 I right mouse clicked on the url of favorite websites then drag and drop on the firefox icon in the taskbar and that was it. On Windows 11 that no longer works. How do I pin my favorite websites to the firefox icon in the taskbar on Windows 11? I thank anyone for your help.

I'm on v137 on Windows 10.

I cannot play my Unifi camera videos because they require HEVC. I thought v134 and higher had HEVC support?

There were some mentions of needing to get the HEVC codec from the Windows Store, but I could also not locate that from Microsoft either.

Under about:support, it says HEVC is Unsupported. What am I missing?

Hello

I use Firefox 132.0.1 under Fedora 14 Linux. Whenever I click an urls in another application (e.g. Libreoffice, Keepass...) a new tab is opened in Firefox (according to Firefox's settings), but Firefox itself does not pop up in the foreground, it remains in the background. I highly appreciate the setting 'open links in tabs instead of new windows'. But FF only comes to foreground in case I deactivate 'open links in tabs instead of new windows'. How can I prevent FF to stay in the background in case 'open links in tabs instead of new windows' is enabled?

Thank you in advance

Since 113 I have had tabs BELOW the Bookmarks toolbar i.e. at the top of the "blank" screen area.

133 has now regressed my setup, back to having tabs above the address bar. This is a bad move, as it means that once again the screen content of a tab is separated from the tab by two bars, Address and Bookmarks.

Can anyone point me to a setting or a userChrome code block that will put the tabs below the Bookmarks bar, as the css now no longer works as it stands on 133?

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.
