When copying and pasting from one application to another, by using Ctrl + Shift + V to paste without format to Google Docs, I keep getting a "Paste" pop up that I've never gotten until now. It keeps getting in the way and I don't see a way to remove it.

It's making copying and pasting very difficult and is driving me up the wall.

When trying to set Firefox to open a file on Windows 11, it is overwritten by Firefox Nightly. I have both branches installed.

This is how it goes when attempting to set Firefox as a default application in my machine:

1. "Apps > Default Apps"
2. .mp4 (for example)
3. click the button below that displays the current default application
4. Firefox Nightly appears in this menu
5. "Choose an app on your PC"
6. "C:\Program Files\Mozilla Firefox" ... "firefox.exe" ... "Open"
7. Firefox Nightly remains in this menu

I cannot get Firefox to appear as an available app in this menu. The only workaround, although inconvenient, is to drag and drop files straight into Firefox.

Any help would be much appreciated. Thanks.

I need to disable the "command I" keystroke because it is causing alot of problems when I hit it. I am on a Mac and use a Protooarc EK01+ keyboard, This keyboard has a "settings" key and when I peess it by accident, it dislays the Ihfo dialog screen (and erases what I've already typed. Can you help me, please?

Firefox 148.0.2

how do I click ok to do this? Double-click the browser.sessionstore.max_tabs_undo preference to display a dialog where you can enter the desired value, which in your case might be 0 and then click OK. I have an HP desktop running windows 11 and have been unable to prevent history from keeping recently closed tabs.

not a real question and not waiting for answer.

the "Open all in tabs" menu that appears at the bottom waiting for you to click on it by mistake. we need a way to remove that option while also disabling the middle button over the folder to open all bookmarks over the tabs. It also should be a default because been using firefox since version 1 (previously Netscape Navigator back in 1998) and I rarely had the need for something like that.

Firefox under linux x64 v 148.0.2

Linux madcat8.local 6.12.30 #1 SMP PREEMPT_DYNAMIC Thu May 22 18:38:20 CDT 2025 x86_64 Intel(R) Core(TM) i9-14900K GenuineIntel GNU/Linux

asked chatgpt and it suggested some fixes but apparently userChrome.css is actively being ignored. from the look of things, seems like I will have to stick to an specific version like I had to do with Thunderbird after version 102 where ugly UI changes were implemented.

have fun.

I went to settings, general and tabs. While I was trying different tab settings I accidentally changed the function of the F11 & F12 tabs. How do I return them to their default setting?

After a recent change the browser scroll always goes to the bottom of the page. Before it was always at the top of the page. I found no way in Firefox to reset this function.

Hello, Firefox. So I have this feature whenever I type. When I type my first letter, it is capital, and whenever I add an comma to my sentence and hit the space key, it adds an period. I don't remember enabling that feature, and I want to disable that feature. Is there any way if I can disable that feature? Thanks in advance!

I am using Debian Trixie with firefox 148 and I reported that the refresh option was missing from Firefox, https://support.mozilla.org/en-US/questions/1569549. I then noticed another workstation with the same version of FF that did not have the "refresh firefox" option.

It appears firefox has been changed. Some of the items have been changed including the profiles option to add color on creation.

How can the parameters of FF be changed ? See enclosed menu under help, "more trouble shooting information", you will see "refresh firefox" is missing from the top right.

Mozilla currently allows a user to select an AI Chatbot to use in the updated sidebar. The choices are limited to Anthropic Claude, ChatGPT, Google Gemini, Le Chat Mistral and Microsoft Copilot. When will Mozilla add Grok to this list of choices?

I have reset Firefox as default browser on my Windows 11 PC a hundred times in the past few months. Today, I could not reset it at all -- I click the default button in Windows 11 and as soon as I close that settings window, it disconnects. I've run out of things to try to fix this. I think it MIGHT be related to Norton 360, because I first notice this problem when I opened Norton.

There seems to be no possible way to change the shortcut for peeking at the tabs in the sidebar (when sidebar revamp is enabled) from the about:keyboard UI. I have so far managed to modify the shortcut through intercepting function calls.

What I have done: 1. Read through the JS source code for about:keyboard which says the shortcut ID is `toggleSidebarKb` 2. Added hooks to intercept `RPMSendQuery` calls 3. Modified the shortcut through devtools open on the about:keyboard page with the following snippet

```js await RPMSendQuery("CustomKeys:ChangeKey", {

 "modifiers": "accel",
 "isValid": true,
 "key": "S",
 "shortcut": "Ctrl+S",
 "id": "toggleSidebarKb"

}) ```

The way I am doing it is definitely a hack. I am not sure if I am missing something. Although the shortcuts for bookmarks, history, and GenAI chat sidebar are present, there seems to be no entry to change the sidebar toggle shortcut itself. I'd love to work on this but I haven't been able to mach bootstrap on NixOS.

Thank you for any assistance :)

I started using Claude in the side panel instead of a dedicated tab, but there is something noise about it: every time I click to open the side panel the chat starts from scratch. Getting a clean slate is nice, but it takes too much time loading. So I would like to not unload the content of the panel when I close it, just hide it, so when I click to open is already loaded. There is a way to do that?
