Hi,

I'm using Firefox ESR 78.15 with a slightly modified Arkenfox user.js

I keep getting two "Unknown Collection" messages in the console after startup.

The first one reads Unknown Collection "main/messaging-experiments" in the headline, while the following text is shown in the drop down menu: "UnknownCollectionError resource://services-settings/RemoteSettingsClient.jsm:155 sync resource://services-settings/RemoteSettingsClient.jsm:455 InterpretGeneratorResume self-hosted:1158 AsyncFunctionNext self-hosted:693

The second one reads "Unknown Collection "main/cfr-fxa" in the headline, with the same text in the drop down menu as above.

Can someone please explain what these messages mean and if it is something to be concerned about?

I've spent quite some time, but couldn't find out.

Thanks

I have various versions of Dell OMSA (OpenManage Server Administrator) on about 20 servers running Windows Server 2008 and up, and all of them have stopped working with FF 94.02 (and possibly 94.01)

OMSA gets stuck in a login loop, just keeps asking for credentials. Switching to latest Chrome works, but I'd rather stick with FF.

Any ideas on what setting may have changed to create this issue?

When I open Firefox a tiny window appears with nothing but a button and it does not open. When I click the button it just closes. same thing happens when I open the developer edition as well but in that the main window appears but does not load.

This used to happen intermittently since few months ago. When that happens closing that tiny window and reopening the app usually worked. but it outright does not open anymore

Happened on Win 10 now on Win 11

when I reinstall Firefox it opens up normally. but when I restart my pc this happens again.

Edit: Tried reinstalling to open Firefox now it does not even open like that anymore.

Hello,

I have a new Cisco Webex Desk Camera that it's not working with Firefox (Flatpak on Fedora Silverblue 35).

lsusb: Bus 006 Device 004: ID 05a6:0023 Cisco Systems, Inc. Cisco Webex Desk Camera

https://mozilla.github.io/webrtc-landing/gum_test.html shows two cameras "Video Capture 4" and "Video Capture 5", none of them work, the page shows an error message: "AbortError: Starting videoinput failed".

The same website works in Chromium (also a Flatpak), which only sees "Video Capture 4 (05a6:0023)". "OBS Studio" is also able to use the camera. "Video Capture 5" is not available in Chromium and freezes the image in OBS Studio. I believe Video Capture 5 is the IR camera that is used in Windows Hello.

Would you be able to help me to get this camera supported, please?

I suddenly can't watch my Youtube TV account. Every time I try to play a feed or a recording it takes a little bit to load then a message appears saying "Sorry, there was an error licensing the video." I've checked my Youtube TV account and everything checks out, restarted my browser, started browser in safe mode. I tried using Internet Explorer and it worked on that, then it worked on Firefox. I closed the Internet Explorer then the Firefox stopped working. Not sure what's going on.

I was recently watching a Twitch livestream when I stepped away from my PC for a moment and upon returning found it sitting at the login screen. Checking eventvwr it showed a BSOD event had occurred. The only thing actively running on my PC was FireFox with a single tab for Twitch.

Level: Critical Source: Kernal-Power Event ID: 41 BugCheckCode: 307 decimal, 0x133 hex

Windows documentation lists hex 0x133 as a DPC_WATCHDOG_VIOLATION error, and since Parameter 1 was a '0', it states, "A single DPC or ISR exceeded its time allotment. The offending component can usually be identified with a stack trace." https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x133-dpc-watchdog-violation

From Windows Debugging Tools I loaded up the DMP file and ran !analyze to see the process name listed as FF (there's more information listed, just not sure it's really useful).

I checked FF `about:crashes` and it doesn't show any crash report there (presumably because the system BSOD and it did not have a chance to do anything).

Just wondering if anyone else has seen this issue and how/if they resolved it. In searching around it seemed like some folks suggested disabling hardware acceleration as there may be incompatibility issues with FF and GPU drivers. I checked under FF settings and it has "Use recommended performance settings" enabled, but there are no sub-options specific for hardware acceleration.

Some basic system specs: MoBo: Gigabyte B550 Vision D-P (BIOS F13e, latest available) CPU: AMX Ryzen 7 5800X GPU: Gigabyte GeForce 3060Ti (driver 30.0.14.7141, latest one available)

Running on FF 94.0.2 (64-bit), the latest update.

Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.

I am experiencing a problem with lockwise since months. In just few words I cannot see which password are stored and therefore I cannot even edit them (see the pict). The funny part is that the login/passwords data are there because I can use them after landing on any page where I have an account. That's to say that the only way I have to edit a password that I changed on a different browser is to visit the page and then change it. Another few examples? 1) If I enter in the search box any of the sites that should be (and indeed are) there, it cannot retrieve anything. 2) If I click insert new credential it does nothing (no box where to insert the new data)

Note! Browser update 94.0.2 (Mac) Logged in my FF account and Sync activated.

Continuing to have issues with pinned tabs and, worse, Firefox crashing...like y'day with loss of all pinned tabs on powering up today?! Have posted issue several times with "FredMcD" being unable to help but who escalated the problem...with no response from Mozilla/Firefox! Needlessly spending a great deal of time restoring pinned tabs but sometimes cannot find them all. Does the "800 lbs" Mozilla care?

Hello together.

I'm experiencing the same problem as discussed in this cases that is not solved yet: https://support.mozilla.org/en-US/questions/1312836 https://support.mozilla.org/en-US/questions/1333547 https://support.mozilla.org/en-US/questions/1321038

Symptoms: After FF starting it loads pages fast enough. After several minutes of using pages start be loading very slow. Loading slowness increases until it becomes blocked continuously. Reload button has no effect. I tried everything from here: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - No effect.

Work around done: When windows is loading in Safe Mode the problem disappeared. If I disable Windows Defender Firewall the the problem disappear and appear after firewall enabling again in several minutes (same as after FF restarting) When I go to <current network settings> and switch Network Profile from Public to Private or from Private to Public the problem disappear but goes back just in several minutes (same as after FF restarting). Windows 10 Restorehealth has no effect, and reports that everything is OK with system files (DISM.exe /Online /Cleanup-image /Restorehealth ) The most strange thing Windows 10 In-place Upgrade has no effect.


I found out the core of problem is that Windows Firewall is blocking FF internal interprocess communication on local TCP ports. Yes, you would say it is not possible and firewall doesn't affect local port communication but in my case it is a fact. I used the ProcessMonitor from Windows Sysinternals, and Windows Defender Firewall with Advanced Security log. Screenshots shows this fact. On first two lines from Firewall log you see a Local Port Communication blocking, on ports 1401 and 1400. Next Screenshot from ProcessMonitor shows (see blue colored lines) that it was exactly FF communication, where I was trying to reload a page several times.

Any ideas what to do with it? It seems like Microsoft’s way fighting a concurrent web browsers, but I hope it isn’t.

Now I use FF version 94 but the problem starts from 88. I was trying FF downgrading to version 75 with no effect.

Whenever I am viewing a PDF and wish to download it or save a file from firefox, the save dialogue of the finder and where to save it does not appear. Only the initial firefox option of "Open file" or Save As dialogue appears. Once pressing Save As, nothing else happens. Furthermore when simply pressing Cmd + S to save the PDF no dialouge appears. When typing this message and attempting to add an image of a screenshot, once again the finder dialogue to select a file does not appear.

Is this a mac issue or firefox problem? I am running Mac OS 12.0.1 Monterey.

As the subject says, when attempting to upload images from my computer (Ubuntu 20.04 on Firefox 94), often but not always, the result will be a visual glitch similar to the image attached. The only time which I have ever used Zoom on Firefox, the same issue happened when I tried to use my webcam, except that the lines rapidly changed colours.

I apologize if this issue has been solved in another thread, but this is a bit hard to describe without the picture, so my attempts to search for said thread were unsuccessful.

The issue is not present when I upload the images in question via mobile. Turning off my extensions has no effect.

The image attached is taken directly from attempting to upload a profile picture to my Firefox account, but I have experienced this issue with websites like Twitter and Ebay for example. I have never had this issue with Imgur, for example, even though I am doing nothing different (uploading images). I do not know why this only occurs for a select few websites.

Any responses or help is appreciated!

firefox randomly inverts caps lock and numlock, and when that happens, also I can't delete tabs nor go to one tab to another unless I do three finger press the touchpad to delete a tab, also when you do create a new tab, it will open a whole new window

By inverting the caps/num lock I do mean that if they are active, then firefox get the input as if they weren't and viceversa

but if I do try to write into the numpad then the issue is not there, then if I do try to write again into firefox, the issues are not anymore present, the same happens when I do try to record the issue with obs, once that I do press record, then the issues will not be any more present

I did try a clean install, and the issues are still there, with and without addons, the issue seems to appear randomly, and always at the same time, I mean if the caps become reversed, then it will also prohibit me to gui delete a tab, to switch from one tab to another (but both do become highlighted by the gui), and opening each new tab into a new window
