I know I can hide the sidebar by clicking the button on the toolbar. But I'm used to opening my bookmarks and history with ctrl+b and ctrl+h, and being able to close them the same way. This still works to close the actual bookmarks/history, but the sidebar doesn't return to being hidden (despite being hidden before I opened them), it hangs around taking up space on the left of my screen. Even after I removed everything so it's just a useless blank rectangle with "customise sidebar" at the bottom, it defaults to staying open unless I click the button. It's really annoying. Is there any way to make it hide itself again automatically once I'm done using it?

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 the article https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended

https://packages.mozilla.org/apt leads to 404, not a Debian software repository / archive.

Step 4 (is broken)

Next, add the Mozilla APT repository to your sources list:

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

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!

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.

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?

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.

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?

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.

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.

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.......................

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

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?

My husband's Windows computer failed, and I am setting up his new Chromebook as a holiday gift.

Unfortunately, the instructions for setting Private Mode as the default for Firefox don't fit what I see on the Acer Chromebook 315.

Please provide appropriate instructions. I want to place it in his office, ready to go, before he gets up tomorrow morning, December 25. I am in Central Time in the US.

Hello

I was reading this article: https://support.mozilla.org/en-US/kb/ai-chatbot

In the section: "Select text to see suggested prompts" there is a screenshot which shows pre-written prompts and a textbox from the shortcut for AI prompts menu. Is it possible to have custom promts which are added to this menu?

Thanks

Best

I have installed the LastPass extension for Firefox, more than once, but the LastPass icon does not appear in my browser bar. It used to be there, but disappeared a few weeks ago. I have tried to reinstall the extension, but it has had no effect.

Helllllllllllp! Just had firefox install an update & now all my saved bookmarks, login passwords & previous home page have all gone. Have reset Home page, checked that Profile is correct & the bookmark folder is empty. Where have they all gone. Yes I have restarted my computer but made no difference.
