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?

I thought this might be a Windows issue, but it appears more likely to be a Firefox problem...... Almost every time Firefox updates itself on one of my several PCs (a Dell), all of my saved logins are removed.

After some checking, I found that the actual logins file had been changed from "logins.json" to "logins.json.corrupt".

Why Firefox is doing this is anybodies guess, but it may have something to do with the actual passwords themselves containing characters that it doesn't like.......

Easy resolution - find the "corrupt" file and rename it!

Using Windows Explorer, you will need to make hidden files visible, then go to (User)>Appdata>Roaming>Mozilla>Firefox>Profiles>(71r822oe.*********), then scrol down to "logins.json.corrupt" - select, rename, "logins.json", agree to the change warning, and exit. All now works as before.

(The bits in brackets will be your own name and registry entry)

Please, Mozilla - can you try and stop this happening in the first place ?

I have AVAST running on my computer in passive mode; I simply have not bothered to remove it, fearing screwing something up. Now, AVAST has stripped all my saved passwords from FIREFOX. Can I load these back into Firefox from my renegade AVAST?

A lot of websites are difficult to use when they track, and I'd rather access them only in incognito mode. Is there a way to create a list of websites that only open in incognito (preferably just automatically launching an incognito window)? If not, can I request it as a feature?

I'd also like to create a blacklist for websites from appearing in highlights on my homepage. Can I do that? If not can I request it as a feature?

Thanks so much!

I just switched to Firefox from Chrome and so far Im loving it, except for one tiny bit, which unfortunatly drives me crazy:

When I use the search from the adress bar to look up functions with dots '.' in them, Firefox always assumes these are websites, add 'www.' and takes me to ' Site could not be loaded' instead of using google to search.

Is there any way to change this behaviour in the adress bar?

In Firefox 55 (2017) does it still make sense to move the cache to RAM?

I refer to the classic case where I have an SSD and don't want to "consume" it by watching endless videos on YouTube (and/or other sites) that are being buffered to the disk. Or does the buffering of such videos occur in RAM by default in Firefox?

I also want to speed up Firefox at the maximum.

What are the downsides of having the entire cache in RAM and, if none, why isn't the default instalation with no cache at all on the disk (browser.cache.disk.enable = false) ?

What is the best configuration of Firefox (regarding cache) on a laptop with the an SSD and 4 GB of RAM?

Thanks in advance.

Starting yesterday when I turn on my computer, or after it has been in use for some hours, totally unexpectedly, unasked for, suddenly a commercial comes on, a speaking voice with background music - it can interrupt whatever is already going on, is not identified in any way, no accompanying images, and therefore of course how can I get rid of it?

Recently had a HD crash and had to re-install windows and all my browsers.

Previously, Firefox would immediately load all my previous tab but now I have to click on each one to get them to load. I have looked in the options and there is no longer a checkbox to tell Firefox to load these tab immediately. The previous version I was using had this option.

Is it still available and if so, where do I find it to enable it?

Regards Brad

Just using Adblock Plus and Firefox internal adblock is not enough to block all popups from, errr, popping up. I tried changing "dom.popup_allowed_events default" to blank in about:config. That worked, no more popups but I could not upload any thing as it also blocked the file browsing popup -.- I want to ask if there's a way to block every popup apart from the file browsing popup.

Hi here!! I review a lot of mozilla docs (out dated or without complete info), forums, googling ... about how to share firefox/thunderbird/ligthing data between platforms on dual/multiple boot system. Every user in same trouble are repeating (copy/paste) in the solution to share the SAME FULL PROFILE on all platforms. I review profile data and folders and I can see files and config data that are platform dependent; then I think that share FULL PROFILE between is not the best approach, for example Linux and Windows will produce several problems (and a lot of problems with the add-ons) In these same mozilla docs recommends to share only data and maintain custom profile for each platform, but not more info how to do it. Please can some kind advanced :) provide some info about the correct approach. Or a better tech info about how is possible the recommendation of sharing same profile between platforms without problems. Because with the current doc info, there is no way to get a clear answer (Almost I can't :~). Thx guys!
