Firefox Headless ---Screenshot not working for local HTML files

I'm unable to generate a screenshot of a local HTML file using Firefox's (v60.9.0) [headless mode][1]

Here's the command I'm using:

   "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P AJ --screenshot test.png "file:///C:/html_export.html"

I've tried with and without a profile and with different numbers of slashes after file. There are no errors in the command line - it just doesn't generate an output.

This command works fine when I substitute the file:// with an external website like:

   "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P AJ --screenshot test.png google.com

Could it be related to the [redirect bug mentioned here][2]?

Any help is appreciated! Perhaps theres a way to turn on output verbosity for --headless mode?

Where are my existing Questions etc from the "Firefox" account linked to this new system? It promised that they would be linked if I used the same email. Nothing is in my Profile - I want my list of previous Questions !!!

Should have send everyone email warning of this. New account creation page should have option to enter existing UserName & be sent an email, so you know what email was being used. Over the years there have been many. Also different emails for "Get Satisfaction" (Is that defunct?) & for sending questions to Developers and AddOn authors...

I used the address that I found searching old email for announcements sent by Firefox/Mozilla, so it SHOULD be the one I used "here."

Hi, I'm trying to get the en-GB dictionary to silently install (for network deployment) into firefox, I've got the dictionary xpi, it's file name is ID, and it's dropped into the extensions folder. Firefox detects it and after changing the autoenablescope setting, it is automatically enabled within FF. However it is not actually active and working as it should (no spellcheck or underlining). By installing through the normal add-ons page it does work, of course. But not when installed and activated the silent way.

Any help would be appreciated.

I have a Windows 10 Pro X64 Lenovo which is domain joined. The user frequently uses Firefox as their browser. When they do, they can get frequent and repeating Blue Screens. When I look at the memory dump files, I see that the faulting application is Firefox. Can somebody assist me with this file and offer some insight into how I can circumvent further disasters?

I do have the memory.dmp file. Can I share it?

Hi. I've been a loyal user to Mozilla Firefox for many years now. My concern is whenever I updated the browser from the past, It deletes my settings and extensions. That's whats keeping me from updating it for quite sometime now. So Im simply afraid to do it. For example. Part of my research entails an extension that downloads and converts from a video site. After an update this is removed. I have to re-install everytime. I so got tired of this. Its so annoying everytime it asks for updating, I have to opt out. Is there some way I can update this without messing up my settings? Has Mozilla already worked out a version without messing with my settings? Thank you for the help.

Greetings,

I'm setting a staging server on a VM, and issued a self-signed certificate.

When accessing https://staging.my.site firefox is giving me the following error:

" The owner of staging.my.site has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate. "

Clicking on Advanced shows:

" staging.my.site uses an invalid security certificate. The certificate is not trusted because it is self-signed. Error code: SEC_ERROR_UNKNOWN_ISSUER "

There is no way to add an exception.

I went into Preferences-Certificates-View Certificates / Servers-Add Exception. Typed "https://staging.my.site", clicked on Get Certificate-Confirm Security Exception. But I got the same message

Restarted FF. Same message. Checked in SecurityPreloadState.txt but cannot see mention of "staging.my.site"

Kindly indicate me how to add an exception for my staging site.

Regards

Search for the addon on mozilla addons.

Locate UBlock Origin and click install. The popup is displayed to 'accept' permissions. Click accept and nothing happens. In the addons 'extensions' tab, the ublock entry row shows, but it never starts to download (and therefore never installs).

Tried to do it by saving the xpi to local and installing from there, but exactly same thing occurs.

Firefox 60.x ESR on Linux (slackware).

Is there anything else I might try please ?

I successfully make FF my default browser and it remains such for the current session. Session = one continuous login period. After restarting or shutting down/powering up the PC (Windows 10), the browser is reset to Internet Explorer.

So every session, I have to set FF as my default browser. Microsoft seems to make other makers' applications less accessible by insisting on defaulting to Microsoft products when available.

Firefox versions in the 50's had been doing pretty well minimizing crashes. I updated to v.60.0 recently, and it constantly hangs. Fortunately, I usually have more than one tab open, so I simply close out of the hanging tab(s), and can usually just open a new one without it having to bring the entire browser down. Aside from that, it's just really slow and problematic. Not sure what was changed. In any case, here are the crashes I had just yesterday:

bp-cd57c830-ab65-46f5-b007-c18be0180513 bp-4d483162-7e08-484f-bd7e-9dfbe0180513 bp-4a7c4094-557e-4ea7-a047-af3f30180513 bp-a9eb3715-8739-4a43-a27b-8a4fb0180513 bp-18b954f6-8340-4074-b1cb-4a2160180513 bp-5254ff5f-8ee0-4d27-88ea-915570180513 bp-41c8b7f5-68a0-4ccc-940a-430ac0180513

Just from tonight:

More shutdown kills, unfortunately. I hadn't been experiencing this for many versions and thought it'd been solved.

I tried Fennec F-Droid, a Firefox version built from source without proprietary code, signed into Firefox Sync, but after renaming the device, the device manager kept showing it as the default name. Changed two or three names, then gave up and installed regular Firefox. Now when I click on "Send Tab to Device" the menu shows the names I entered for the device which were not working, but the device manager shows only the actually connected devices, so those names are saved somewhere. This error is persistent with all the devices I synced. How do I remove them?
