I'm trying to create a Drag & Drop file feature in my web page following this doc https://developer.mozilla.org/en-US/docs/Web/API/HTML_Drag_and_Drop_API/File_drag_and_drop

The dropHandler function works as expected the first time I tried to drop a file into a "drop area" div, but then does not work anymore. In all subsequent calls, the drop event is triggered but there is no file in

`` event.dataTransfer.items // empty event.dataTransfer.files // empty ```

This behavior is the same in Troubleshoot Mode.

Firefox version: 123.0.1 (64 bits) OS: Debian 12

When Firefox first runs, it works properly. All menus appear properly. At some point after use, a hour or so, all the menus stop appearing. The main menus, right click context menus, hamburger menu, all stop showing up. Even the pull-down menu on this website for "Which topic best describes your question" fails to appear, though I can select an answer by clicking on it and using he down arrow.

Hardware acceleration does not affect it. The problem occurs whether it is on or off. Nothing fixes it except shutting down and restarting Firefox, and that is only a temporary measure, as it inevitably happens again after some use. z

Updating graphics drivers does not fix it. It has been happening over the last three sets of Nvidia driver updates.

Sometimes the menus temporarily return, but soon go away again. They are gone far longer than their short returns.

When I left-click on text and hold the left mouse button, then right-click, first release the right button, then the left button, a "selection mode" is activated, where the end of the selection follows the mouse pointer despite no button is held. In principle this looks like a useful feature (or it would if the scroll wheel worked in that mode, which it doesn't). But at the same time, the context menu opens when the right button is released. So we trigger two features at once, making both less useful, because they're getting in each other's way.

This frequently happens to me when double clicking on a word and right clicking to open the context menu on it. Accidental overlap of the left and right clicks triggers the selection mode.

Can this behaviour be configured (e.g. to use a custom shortcut) or, if not, be deactivated entirely?

I'm using Firefox 123.0.1 on Linux (openSUSE Tumbleweed).

I know you're meant to use up all of your ram, but I typically have other apps pen to multitask.

Hello,

I have cleared cookies, cache, temp files, updated, no translation settings are enabled. repaired and even removed and installed Firefox again. When I click on my Google mail quick button or even just type the URL in to get to my mail. The language displayed appears to be Chinese? The URL for the site shows "zh-cn" I'm in the US, no VPN, no proxy.

Additional troubleshooting:

Tested with Chrome and it appears to be working fine.

Hey!

So since yesterday I can't use my hotmail/outlook anymore!

I can still use it on other browsers & I can just surf the web just fine. But outlook? Nope. Reading messages work, but they still appear as unread when I go back to my inbox. I can't send an email, cant save drafts or do anything.

Pretty frustrating. What can I do? I updated the browser again, rebooted pc & I also tried deleting cookies

My Subject pretty well says it. I'm trying to transfer by syncing my desktop Firefox with the Firefox 124 on a newly installed Kubuntu on a new laptop. I have all these functions synced ON. The recent history but not the long-term history, passwords (thank heavens), and all bookmarks got transferred, but not the open tabs/pages. I've done the desktop sync followed by the laptop sync a few times, still without the tabs' transferring. How do i get those transferred?

Hello, I'm looking to stopping **ALL** website Pop Up Notifications--NOT just selected ones. I've already gone to Privacy & Security-->Notificatications. This is feature is totally pointless. This feature assumes you repeadily go to the same singular site that causes pop ups --not random site you visit. I did check off the button at the bottom "Block new requests asking to allow notifications." My issue is NOT, NOT seeking to block "permissions" (I have never seen or been asked by Firefox to 'allow permission for website notifications')--I'm seeking to stop ALL website pop ups notifications that intrusively just appear at the lower right corner. I don't understand why there isn't a single button to stop these intrusive and annoying pop up pushes??? It's a no brainer. I hope you can help with a solution. Thank you in advanced.

Before updating Firefox to 123.0.1 (64-bit) + MacOS Sonoma, I could use FIDO2 on OnlyKey and login to my proton mail. Now, however something has changed on Firefox that I get presented with two prompts to touch my usb key, but the key itself doesn't respond to the second prompt and login fails.

I first get this prompt as before. I select 'Authenticate' and would be presented with the second picture. Since my key is not expecting to be touched, nothing happens when I touch it and login fails with the message displayed in the last picture.

I am trying to find answers in relation to my Favourites shorcuts not showing the Icon for some well known websites e.g BBC World News, CNN. Once answer found on the Firefox Forum is: Make sure that you allow pages to choose their own fonts.

Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

This is just typical of many answers I find on the Firefox forums whereby the suggested solutions seem to bear no resemblance to my Firefox system. Am I using something different? Everything points to me having the latest up to date version of Firefox. For example if I click on the four horizontal line hamburger on top right of the screen I do not see anything that begins with "Tools" in the menu options. I see "Settings" and "More Tools" but none lead to "Options>Content: Fonts & Colors> Advanced: [X]. simarly, If I click on "Tools" in the menu at the top of the Browser nothing leads to "Options". Any suggestions please?
