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

Hi, I am using Linux Zorin and have updated to a later OS but cannot reinstall my stored files because, "/home/garry/.mozilla/firefox/0czvkt76.default-release/lock". Which has confused me, I have used a Deja Dup backup which uses Duplicity files as per the Zorin programme. Duplicate files are stored in a WD ext hard drive. What can I do to recover my files pls? Appreciate! Cheers, Garry

As stated above: freac.org and GitHub does not open via Firefox (set as default browser)... (timeouts) Access is possible via Google, after signing in to old Google account. If if "settings"/exceptions,etc. need to be made, how to??

Hello and thank you for your help will my question. I'm using the Firefox Browser 78.7.1esr on my laptop with LinuxMint 17.3 installed. This version of Firefox is the most up to date allowed with my current operating system. Everything is working fine. The laptop sits on my desk at home, connected to a secure internet server. I do all my work online and everything has been working great.

Now I receive messages from Mozilla regarding older Firefox Browser versions, including the 78.1.7esr that will no long support signing in to Firefox or the syncing function. I've never used the sync option, however I totally depend on being able to access the Firefox Browser multiple times each day.

If I am understanding this correctly, after March 31, 2024 I will be effectively locked out of my Firefox Browser installation. Is this true? Do I have any other options beyond an update (which is impossible on my current laptop). Any other ideas?

I assume I need to move to a completely new web browser of some sort, although Firefox is great. Anything you can offer by way of ideas or help is greatly appreciated. Thank you for your time.

I usually have firefox running. Sometimes I want to display a file on my computer in firefox. Until today (don't know what happened today) I could; firefox would add a new tab for display of that file. Now it gives me an error, reports, 'Firefox is already running, but not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile'. This is inconvenient.

As you can see in this screenshot, Firefox is constantly bugging me with this popup.

I am not able to find an option to disable it once and for all - and I am not able to set it up as my default browser (professional reasons).

It breaks an automation script that I am working on.

Much appreciated :)

I am using Bookworm 12.5.0 Debian with KDE current and Firefox 115.8.0esr long-term version. All appear current. Spiral Linux is the effective shortcut to the Debian loading in its simplified installation. Firefox opens fine, but the field of display cannot be controlled well. I can use Ctl + 0 to somewhat manage, but otherwise any cursor movement sees the display go crazy. Trying to get the cursor over any point is simply impossible. I am using a different computer now to post this with the virtually identical software. This Intel pad differs from the Beelink Ryzen unit which is the unit going berserk. Is there anything that you can tell me other than the Ctl+0 to modify the operation of the unit. I had swapped out the monitor on the Beelink though I have no idea that the monitor is the problem as I do not have the same issue withDiscover or the desktop or any of the other software. I can open up Konsole and use that or open up OpenOffice or OfficeLibre with no similar issue. Would a different monitor act like that?

With first boot after installing ff223, my HP laptop failed, insisting internal had does not exist. Internal had is 1/2 gig, external had is 2 gig, but completely ignored now. No thumb drive or alternate device recognized. Laptop has Linux Mint 64 but.

FF version Extended Support 115.70esr (64bit) I have set /General/Startup/"Open previous windows and tab" - FF does not restore. It worked as expect before I upgraded opsys (Opensuse15.4 to Opensuse15.5).

Please note: I AM NOT TRYING TO RECOVER FROM BEFORE THE UPGRADE! I am trying to get FF working normally (for me) with my usage and history SINCE the upgrade.

After reading https://support.mozilla.org/mk/questions/1407888 I believe I have tried everything there. FF sometimes restores one single historic tab, sometimes it comes with with one single tab opened to my default page.

1) "sessionstore.jsonlz4" did not exist in the main profile dir. (It does not because I followed instructions in the link above to copy it there and try again).

2) I do have a session file, found in sessionstore-backups dir , displayed with this recommended online converter/translater "https://www.jeffersonscher.com/res/scrounger.html"; it shows the expected windows and tabs.

3) Starting after copying the "sess...jsoniz4" file into the main profile dir, I get one window with one tab displayed; I had about 4-5 windows and 15-20 tabs open when I last closed FF, although when doing research, I often have a 10-dozen windows with 100+ tabs.

4) The History menu does not show a "Restore..." option at all. In the window that did open with a historic tab, the History/RecentlyClosedTabs contains a list of plausible sites, about 10, which may be correct for that window. But there were certainly many that were actually open at the time I shut down FF and the window has only opened one.

Thank you for any help here. Rufus

When I scroll up or down on the touchpad in firefox, it is like I scroll past a certain threshold, and it then sends a "scroll up" or "scroll down" command.

When I do this is Chromium, it's like I'm moving the website with my fingers. Similar to how it would be on a touch screen. In other browsers, the scrolling is not discrete, but continuous.

I love firefox, but this is driving me mad when I'm browsing. Is there any fix for this?

how do I set LC_TIME in firefox in NixOS? firefox does not see LC_TIME (as well as timezone, but this is solved by setting the TZ variable). maybe there is some kind of variable, as in the case of TZ?

After I sign in on a Stackexchange affiliated website on Google chrome, I can then visit any other Stackexchange affiliated websites and I do not need to manually sign in. Google Chrome recognizes that I'm signed in on an SE affiliate and therefore, I'm presented a prompt that asks if I want to either: cancel the automatic sign in or join the community if I've never signed in before.

How can I do this on Firefox? Also, I would like to know how to do this because it creates a complicated situation when I need to suggest to a newer user that they should ask their question on a different affiliate. I mean, it seems kind of sketchy to tell someone to "create a new account but make sure to use the same username and password". Like, that's how password stealing scams work.

But with Google Chrome, it recognizes that SE sites are affiliated and so the username and password (or the cookie for the logged in session or whatever it is) is automatically and securely submitted to the other SE site without user input. There's less confusion and an extra layer of automatic verification that the user doesn't have to worry about. This follows the basic security practice of never submitting credentials after you're already signed in on Facebook or any other social media site — if you are already signed in to your account and you are requested to "sign in to facebook to continue" for example on another site or when opening a link, it should automatically sign you in when you refresh the page. If not, then it's likely a spoofed sign in dialog or cloned web page trying to steal your password.

At the very least, it should autofill if it is a legit sign in dialog. But Firefox does not do this on SE affiliated websites and we basically have to create individual accounts, with the same username and password, on each SE website. I literally have to click to create a new account or sign in, go through my settings, copy my saved password from another SE site and submit that with my email.

Lastly, this also applies to SE affiliates that don't have "stackexchange" in the URL such as Superuser and AskUbuntu. I can sign in on AskUbuntu and then when I go to Math Stackexchange or Superuser, I'm automatically signed in.

In the screenshots, you can see how there is the option to "join this community" when using Google Chrome. This option doesn't exist when using Firefox. After joining, there's an additional confirmation prompt that explains about automatic sign in, which also does not happen on Firefox.

https://chat.openai.com/ ChatGPT was working perfectly in FireFox until recently. Still works for me in Chrome and Opera. In FireFox any question to bot freezes window - nothing happens. Same stuff on other browsers mentioned gives results. Tested at different times of day. All updates for FireFox are installed.

In the network tab, I can see all the html, css, and js loaded on my page.

When I click on Start performance analysis (stopwatch icon in bottom left), it shows pie charts of the asset sizes, but CSS is missing.

When I click the back button, the network tab only shows 14 items, and no CSS.

I'm using Firefox on Linux Mint, installed through the software manager.

2 questions

1.: How to build a web page, that enables FF's reader view?

2.: Is it possible, to customize the reader view to include the full URL instead the domain name only?

The twitter videos are not getting played in Firefox, details are below:
