I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

I do not and will not manually close my browser session every time I want to shut down my computer in order to get it to do what it's supposed to. Linux sends SIGTERM to all running processes on shutdown. Firefox isn't handling this correctly, obviously, because if it was, then my settings would be getting respected. SIGTERM is the standard signal sent to windows that need to close gracefully and are expected to still be functional.

NOTE: Do not provide windows-specific support to this thread. I am not running firefox on windows, and I do not possess a windows computer or license.

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

I am trying to download a spreadsheet file which has a .xlsx extension. Firefox insists on downloading the file (my default action) but I want to be given the option to open in my spreadsheet program (Libreoffice).

Looking in Settings and scrolling down to Files and Applications -> Applications, there are other spreadsheet formats present but not one for .xlsx. How do I add the "Always Ask" option for .xlsx files?

Libreoffice is the default system application for opening these files.

Hi all. Did a search but found nothing that helped. Just updated my Fedora 36 workstation and tried to play videos in CNN and MSNBC web sites and get the error message: "Code: 4 | Message: Something went wrong during native playback." I am using the latest Firefox WEB browser. UTube videos are playing fine. Someone has stated on the Fedora forum that they have the same problem but has no problem in Chrome on the same machine. Any ideas? Thanks in advance. Bob BTW, this happened in two machines running Fedora 36 and Firefox 101.0.

The problem is : Some of the time FF just records 0 bytes file and says nothing. I suspect that FF inspect the URL of the links and discard ( perhaps for security reason ) ones that do not begin with HTTP.

The bypass is : One has to copy the link and insert in in the new page of FF.

The solution would be to change FF code.

Thank you.

I'm using 64-bit Linux Mint 20.3 LTS, and the latest version of Firefox from the repositories (101). Suddenly, for no reason I know, my default profile has started crashing immediately on trying to run Firefox. A small window comes up with the error message

XML Parsing Error: not well-formed Location: chrome://browser/content/browser.xhtml

     <button when-cofnection}"secure-cert-user-overridden"="" <="" pre="">

and then a line of ------^ where the ^ indicates between the t and the i of cofnection

Yes, I emphasise that I HAVE copied the error message carefully, including the mismatched bracket pair and the cofnection rather than (I assume) connection

I've managed to get a working version of Firefox by creating a new profile and using that (as in for posting this request for help), and I do have a recent backup of my bookmarks, but it will be a royal PITA if all my logins and passwords have disappeared. I don't want to go any further than this without some guidance, as all the messages I've found detailing how to fix this seem to make the assumption that I'm running Windows.

Can anybody help, please?

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

Basically, a requested relaunch blanked my profile and I can't get it back.

I have a lengthy workaround that will take over an hour to fix from backups, before this incident, but I'd really like to understand what's going on. How can my add-ons, bookmarks, history, logins, etc. be gone? If I did a refresh on purpose, why would my shortcuts remain intact? And, I started by backing up my profile folder to a neutral spot, so why isn't replacing it reversing the changes?

As background: The "about:profiles/Restart With Add-ons disabled" button brings up a small button dialogue to choose "refresh" or default "open." I selected "open" because I didn't want to fix my profile and assumed I would relaunch with only add-ons disabled, so this was a potential point of screw-up. I assume selecting "refresh" would reset application defaults and make a mess exactly like I find myself in now. Shouldn't "Restart with Add-ons disabled/Open" relaunch a temporary and reversible state? Doesn't "refresh" prompt a new default profile?

Considering evidence only, it appears I did something to roast my profile before I backed it up, but that's strange and really out in the weeds, and I'm assuming I wrecked it with my current activity.

The default profile name and path are correct. My shortcut links and labels that I use for a home page are intact but with icons missing, the same appearance as if I deleted the cache; is this detail part of application settings and not profile?

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

Hi,

I use Mendeley Web Extension to pull articles and other things from Firefox directly into my Mendeley library. I will usually rapidly read through the PDF file online before deciding to add it or not. For some unknown reason, Firefox blocks the use of Mendeley on PDF file, for security reasons, and I can no longer add them to my library. Most references are only available as PDF files making the add-on completely useless. Is there a security feature that I can disable to be able to use the extension again?

Kind regards,

Mathias

Using Firefox 100.0.1. Debian Linux. Dell 1525 with 4G ram.

When playing a certain mp3 file in the browser, if I use the arrow keys, or the mouse, to skip forward or back, there is no response, but the audio stops playing for a period of time, then, finally it starts playing again at the spot it was before.

This does not happen with this file in Chrome, or in VLC. Also, with other mp3s it does not happen in Firefox.

I finally got it to work by converting the file to ogg vorbis, but this is not something I want to make a practice of..

I imported the file back into Audacity, and re-exported it as an mp3. Same result.

Weird... Any ideas?

Thanks,
