Everytime I drag a GIF image from one tab to an upload box in another, the file uploads as image.png.

I'd love to find a way to solve this so I don't have to go through the whole rigamaroll of downloading a file, uploading a file, and then deleting said file from my downloads folder.

Thanks!

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

Moments ago I rebooted my computer after a long day of heavy use (it's old). After rebooting and opening my Firebox Browser, I noticed all my Bookmarks were gone. I created a Firefox Bookmarks Export file on another desktop computer using a thumb drive and plugged it into my current desktop computer, and imported the Bookmarks. Great. They all seem to be there again. But the entire appearance of all the websites I regularly use have changed. I use Google Calendar and all the colors are gone. On my other computer, all the different tasks I've created still retain their colors with white lettering, but on this latest version of Ubuntu machine after the reboot, all by tasks are plain white with Black lettering. I compared the settings for Appearance on my two different computers and they are exactly the same. I couldn't Login to X on this machine after doing so numerous times, and after I logged into Bluesky, the appearance was completely different. I don't know what happened. The two attached screen grabs show the difference between this computer and my other one which still shows the color combinations that I want back within Google Calendar. Any idea what went wrong? Also, I tried to click the checkbox below that says, "Email me when someone answers the thread," and I could not. It wouldn't accept the check mark.

It works in Chromium 139 , Firefox ESR 128 , and latest WPS Office. HOW IF A CHINESE USER CANNOT TYPE CHINESE IN LATEST NIGHTLY (Debian forky/sid ,Linux kernel 6.16-rc7-amd64)

This keeps happening and is getting worse every day.

Firefox is refusing to load tabs sometimes every few hours but recently every few minutes so I have to shut it down and restart it, sometimes when I do I lose all my pinned and non pinned tabs, I can't remember what they are so manually restoring them doesn't work.

There should be a way to backup all tabs so they can be restored when this happens.

FIX IT FFS.

OS: Linux Mint Latest update of Firefox

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

I apologize for repeating the question, but I wanted to write about the system requirements for the computer. Where can I find this information, and if something has changed, what are the system requirements for the computer?

Usually, when I start typing the address of a website I visit frequently, Firefox will suggest the complete address. Now, for the last week or so, it doesn't. For example, if I start typing guardian.com, the default is to search, and then only when I type the final "m" does it switch to "visit" when I press enter.

In settings, under Search, and Address bar, the box to suggest browsing history is checked, and at about:config, browser.urlbar.autofill is set to true.

I have Firefox version 141.0.3

I use Firefox on Windows. I like it. But I also have an HP Chromrbook and I would rather use Firefox than Chrome. But I really don't want to do the entire Linux dance. Is there an easier way to get Firefox for my HP Chromebook?

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

This is one of the more annoying messages Firefox has recently added:

"Your browser is being managed by your organisation."

It is obviously wrong, because it is shown on a private Ubuntu 24.04 computer where I have myself installed Firefox from a tarball installation (Firefox version 142.0.1).

The about:policies page just shows: Homepage: URL "https://start.ubuntu-mate.org/"

  Locked	false
  StartPage	"homepage"

Why does Firefox give such obviously misleading information? All the other articles are not helpful at all either, some are talking about security software, some about malware.

This is an extremely user-unfriendly and confusing message: if security software is to blame, why does Firefox not tell what exactly is restricted? When malware changed something why does Firefox not tell what it changed? What even does the message actually imply, what is prevented what otherwise would work and why? What does the information shown on the about:policies page really tell me?

This is by the way shown when starting Firefox using an EMPTY directory for its profile (so making it use a brand new profile), running from a brand new installation directory extracted from a tar file. So what on earth makes it think it is "managed by my organization"?

There is no extension installed, no policies.json file in the newly created profile, nothing. It looks as if the firefox browser would just arrive with this weird setting/configuration comiled right into it?
