Copy, Cut and Paste are not working in Google Sheets or Google Docs using Ctrl-X, Ctrl-C or Ctrl-V. Other control combos do work such as Ctrl-Z, Y and F. These features are working on Chrome with the same files. I disabled extensions and tried the Troubleshoot mode. Neither helped. Using Firefox desktop 138.0.1 on Win-10 Pro.

Cannot access anything on computer because there is an old tab not closed and I'm trying to find how I fo that. I cannot access anything until t h e old tab is closed

Find on Page suddenly stopped working. Neither CTRL + F nor clicking the command on the toolbar do anything. It happens in Troubleshooting mode as well. Restarting Firefox and the computer, refreshing data etc. didn't help.

Firefox just started, seemingly unprompted, replacing - > (without the space) with U+2192. Just visually, however, as moving the cursor left from the end of -> puts it between - and >. This only occurs in Firefox fields such as the url search bar, settings search, Ctrl+F search, and the fields in this form. All other forms unrelated to Firefox as a product or company seem to function as expected.

Hello, Until recently, I was able to double tap the browser bar and have the window expand to fill the screen just short of "full screen" mode so I could still see the menu/task bar. I remember I did need to adjust settings for this somewhere but can no longer figure it out now that it is not functioning to this spec any more.

I did check about:config to see if "apz.allow_double_tap_zooming" was set to TRUE and it is, by following this suggestion below:

Last night, Firefox spontaneously stopped recognizing input from my Logitech M650 L mouse's side buttons used to go back and forward through the browsing history of the current tab. I've tried refreshing firefox, checking the mouse software, trying a different profile, trying firefox in safe mode, checked the firefox config and the mouse button inputs were set to "true", tried clearing the cache, and even tested on a website that shows you your mouse inputs and the side buttons were not detected at all, while all other buttons were detected fine. The side buttons work fine in all other programs and browsers on my PC: Windows 10 64 bit.

There was a brief period where they started working again last night, but seemed to stop upon reboot my computer.

If I use the close window shortcut (ctrl+shift+w) in Firefox it fails to close the window and treats every action I try to take as if the shift and ctrl keys were held down. For example, clicking on a tab will select it as if I were trying to move it as a group, rather than switching to it. Or, pressing only the T key will reopen closed tabs as if I had pressed ctrl+shift+T. This behavior will persist in Firefox until I close out of it completely and reopen. This does not occur when any other application is focused and ctrl+shift+w is pressed, and the effects are isolated to Firefox only when it does occur. Due to this, I do not believe that it is a hardware issue, eg. my keys just getting stuck. I haven't seen anything online that even vaguely resembles this issue. Any solution would be appreciated, even if it is disabling the ctrl+shift+w shortcut, as I keep pressing it out of habit and needing to close and reopen all of my tabs.

I’m having an issue with the Firefox browser regarding the menu bar feature. Every time I press the ALT key on my keyboard, the menu bar appears above the tabs (as shown in the photo). Is there a way to change the ALT key behavior so that the menu bar does not appear when I press it, or to assign a different key for that function?

According to this page: https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly it defines that, when Editing, I should be able to press Home and End to navigate to the start and end of the lines I am on.

Is that an error? I cannot use the Home and End keys at all in this very textarea I am typing in. Command-Left/Command-Right work, but not Home/End.

I have not changed any mappings of my keyboard, and I'm not using any addons. Restarting the browser in troubleshoot mode does not change the behavior.

I've read innumerable posts about this saying to remap it to Command-Left, but I don't want to do that. I want Home to scroll to the top of the page when I am browsing, and to go to the beginning of the line when typing. This is the behavior on Windows, and it should be consistent across versions. If I remap it, then the Home key goes Back a page, which is terrible.

Also no I'm not in caret mode.

Hi,

In other browsers, I zoom PDFs using Ctrl + mouse wheel, but lately in Firefox, this only works intermittently. It functions for a while, then suddenly stops responding. Is this a known bug, or is there a setting I need to enable?

Thanks

When I try to log in to my emails I get a message saying Network Protocol Error. Firefox has experienced a network protocol violation that cannot be repaired. I cannot get into my emails. How do I solve this problem?

I've been noticing that on some websites, certain fonts are hard to read. For example, the letter "e" being too bold or "i" looking like an "l", and "c" sometimes looking like an "o". Those are just a couple of cases. I've attached an annotated screenshot to show this issue.

My eyes aren't so good any more, so this is fairly important. When I want to search, as soon as I start typing and even though the center box is highlighted, the text jumps to the upper box. How do I keep it in the center box? It's probably a setting, but I can't find it.

Thanks to any responders.

When I paste an URL in the address bar with Ctrl+V and then press Enter before releasing Ctrl, the page is opened in a new tab. How can I disable that? I want it in the same tab. (If I release Ctrl and then hold it again before pressing Enter, it opens in the same tab already.)

I need some of my PC screens enlarged -- BUT -- not all of them. Example: Windows Desktop home screen default text size is too small. But Windows applies my custom magnifications to ALL other apps. Firefox text becomes shockingly large and websites become hard to view. Is there a way to change Mozilla's magnification setting independent from Windows? (Note Size difference between Firefox text and Windows taskbar Thanks for your time and expertise!

I have to stay on 134.0b7 where If I type anything in bar, follwoed by Command + Return opens new tab with whatever I asked for.

On new version, this is working with Option key, but it makes no sense.

If I click on a link holding Command key, it opens page in new tab.

Please revert this, to keep consistent with Command key.
