The title says it all: I am wondering whether it is possible to interact with the Firefox console upon starting Firefox in headless mode.

More generally, I'd settle for some way of accessing it programmatically, in scripts.

What I've tried:

So far I've been playing with the Javascript bindings to Selenium without success:

Starting Firefox with the -devtools option from Selenium does opn the dev tools, but I then cannot send key combinations that will switch me to the actual console, or in fact interact from my `.js` script with the open devtools window in any way.

I have a laser printer set as default on a Windows 10 laptop. In Mozilla, when I select print, that laser printer has the green default check, but Mozilla defaults to Microsoft Print to PDF instead. How can I get Mozilla to accept the default printer without deleting Print to PDF which I do sometimes use but don't want as default? Image attached--it auto-checks PDF but you can see the laser listed above it is the default.

Hello

Some days ago my Firefox automatically updated to version 80.0 and with that came an annoying white outline to my windows.

Whenever I full-screen my browser window there are white borders on the sides and bottom, a few millimetres wide. The only way to make them disappear is to scale the window down to about 50% of my screen resolution. This is especially annoying because I enjoy my dark themed Firefox. Below I have added a link to the image.

Safe Mode did not make it disappear, refreshing Firefox did not make it disappear, disabling extensions did not make it disappear. Any help is welcome.

I exported my passwords from dashlane to a csv. The only information in the csv is url, domain, username, password. It is missing the form action, time stamps, and guid. Importing from file did not work. I re-ordered the info so it was in "url","username","password","httpRealm","formActionOrigin","guid","timeCreated","timeLastUsed","timePasswordChanged" format (once again, missing the last 5 fields). I made some fake passwords in firefox to see the format. form action was blank anyways. I tried copying the time info fields (from the fake passwords I made) to my csv, still didn't work. I think I probably need a guid? I tried leaving it blank, didn't work. I tried putting in "unk", didn't work.


I give up, please, how do I import passwords from Dashlane? I can export in json, excel, and csv.

No Little Images on Google Images

All of a sudden, starting a few days ago, when Google Images showed the results of a search, it no longer displayed little pictures with them.

Here are some additional facts:

(1) The missing pictures are still there; you just can't see them. By that, I mean that if you use the mouse to hover over where the picture really is, the cursor changes its form to let you know that it is now over something clickable. And, indeed, if you click there, the program opens a window with the image in question in it.

(2) As far as I can tell, this is happening only with Google Images. For example, YouTube is still correctly displaying the little images for its suggested videos.

(3) I first encountered this behavior on my XP machine, so I thought it might be an XP-related problem. But then I went to my newer machine and discovered that exactly the same thing was happening under Windows 10.

(4) Then I thought it might be a Google Images problem. But then I went to Google Images using other browsers, on both my old machine and my new one, and Google Images worked perfectly normally with those two browsers.

(5) So that meant that it must be some sort of Firefox problem. I waited for it to be fixed by Mozilla, but it wasn't. Then I searched both the Web and the Mozilla "knowledge base" to see what other people were saying about this problem. There wasn't a word about it in either place.

(6) Therefore, I can only conclude that it is a My House problem. But even that doesn't seem to me to make any sense. Here's why:

  • (a) My two computers are running totally different versions of Firefox -- 52.9.0 (32-bit) "ESR" on the old machine [Mozilla won't let anybody running XP have a more recent version], and 80.0.1 (64-bit) on the new one.
  • (b) The machines cannot talk to each other. (They are not networked.)
  • (c) One might guess that some update arrived at both machines and that, regardless of operating systems, that update doesn't handle Google Images properly. But here are three problems with that theory:
    • (i) The Firefox application on the old machine receives no updates any more. The folks at Mozilla have been clear about that. (And it's confirmed by looking at the creation and modification dates on the files in its directory.)
    • (ii) On the new machine, Firefox tells me when it has an update that it wants to install. It had not done so shortly before this new behavior arose.
    • (iii) If the latest, updated version of Firefox 80.0.1 (the version on my new machine) suddenly cannot handle Google Images if the program is being run under Windows 10, I wouldn't be the only person who had been hit by this problem: there would be some comments about it on the Web or in the "knowledge base"

I am totally flummoxed. I've tried clearing the cache, turning off popup-blocking, opening Firefox in its Safe Mode, etc. Nothing helps.

I have Restore Previous Session on Startup unchecked, but Firefox keeps trying to do it anyway. When I have to shut it down because it is not responding, it goes to the bad page when I start it again and gets stuck again. I just got the "We are having trouble restoring your previous session" page, so at least I have a choice now, but why is it trying to restore the previous session when I have the option unchecked?

Hi guys, and thanks for your support, ahead of time.

I have googled everything I can to figure this out and have minimized the memory several times in the settings. Yet, time and time again... especially with Facebook open as the page, I get 100% Disk usage and 4GB ram.

How in the world does one page utilize this much resource? How do I fix it?

Dear community, for some days my Firefox 80 on Windows 10 has shown the message "your system administrator has deactivated updates", when I look under "Help" -> "about Firefox". This is strange, because the admin is me myself, and I didn´t change anything in Firefox or in the Win 10 registry. Has anyone of you had this experience, and how can I possibly fix it? Thanks in advance! Pete

Restoring history from a second device with Sync

Hello,

IT support wiped my browser history on Laptop A. I also have Laptop B, which hasn't been used in a couple of weeks, and which is connected to Laptop A through Sync. Ideally I'd like to import the history from Laptop B to Laptop A, as this would be an almost total restore.

Laptop A losing its history is the most recent activity though, and I'm worried that as soon as I open Firefox on Laptop B, Sync will overwrite B's history with the (now blank) history from A.

So, is it possible to get B's data onto A through Sync, without A wiping B? Can I generate a backup from B through other means without Sync overwriting it?

Many thanks,

Charlotte

I spent an hour with Microsoft support who told me this is a browser problem so I'm here. Firefox is my only browser, Yahoo is my only mail client: I'm up to date with firefox, always.

I have 2 desktops and 1 laptop. I bought the laptop with windows 10, use firefox and chrome and my 2 yahoo mail accounts no problem on the laptop, until a recent windows 10 update. Now I have no contacts and I can't manually insert contacts, it won't save them. I have 2 desktops both windows 7. I upgraded one in January. I don't normally use that computer so I was unaware of any yahoo mail issues. Desktop 2 is using version 18363.1016 while both the laptop and desktop 1 are on 19041.450. I finally gave in and upgraded my daily use computer to windows 10 yesterday 9/3/20. I now have no Yahoo contacts and it won't let me manually input them, it won't save them. So, Yahoo mail is affected on all 3 computers. I checked desktop 2 and there were no contacts there either. I called Microsoft support today, they did all kinds of things...I don't want to use the mail app, I want to use Yahoo mail. Oddly when I switched over to desktop 2 suddenly the contacts were there and everything worked fine . Nothing had been done to that computer...it is configured exactly like the computer I use daily. The laptop and the desktop still do not have Yahoo contacts are are able to save contacts. No clue how I got them on desktop 2, no clue how to get them on laptop and desktop 1. HELP. Thanks

I use the save login info feature in Firefox. I have a saved login for a frequently used website. Firefox reliably fills out the username and password correctly for me. Recently it started asking me every time I log in to "Would you like to update this login?" prompt but with a bogus password. If I press "Update" it changes my password to this bogus password, so I have to press "Don't Update" every time I login just to keep my good password. If I do accidentally press "Update" I have to go to the "Saved Logins and Passwords" and manually fix my password for that website.

My question is, what would cause Firefox to think I have changed my password and give me this prompt when I have not?

And, by the way, the bogus password is always the word: "test" (my correct password is very strong and has over 20 characters).

I'm trying to keep the default as links open in the same tab, rather than a new tab or new window. I've tried Search Settings<Where Results Open, and I've gone into about:config. My configuration is: browser.search.openintab = false browser.urlbar.openintab = false browser.tabs.loadBookmarksInTabs = false </p>

Links keep opening in a new tab, and the "Open results in new tab" slider at the top of the page is always on by default (I can turn it off, but the next time I open a new tab, it's on again by default).

Thanks!

I can't figure out how to get a word count of a web page. The problem: an academic website offers a tremendously long work in five parts--so lengthy I can't copy&paste into Word without getting error messages. The only extension FF has for getting a word (or character) count is Count Me Up, but you have to paste text into a little box. Shouldn't word count be a FF tool? BTW Chrome too doesn't seem to know about any word count extensions.
