Firefox Support Forum

There is a fullscreen mode that prints a window over the full size of the screen without showing toolbars/navigation/extensions... Is there a "full window" mode that do the same, but over the full size of a window? It would be a simple webview in a system window but without the control toolbars. It would be very useful when tiling several Firefox windows without wasting space for toolbars/tabs... This mode should be specific for a window since I do not want to loose the controls on the main screen-wide window.

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 keep getting a unknown pop up after recently up grading FF. I have not seen this before and can`t find out what plugin if any it is coming from. All it does is ask if i want to refresh FF now or later. See the attached image.

I have a website running on a virtual machine on my PC. I access it through m-nlp.test.

Suddenly, my js files are not loaded anymore, although I have not changed anything at the website.

I get the following error/warnings when I open my website with Firefox:

>Loading failed for the with source “http://m-nlp.test/js/index.js?v=4”.

>Content Security Policy: The page's settings blocked the loading of a resource at eval ("script-src").

and the js is not working. I don't understand why a `Content Security Policy` is raised, because the js files that I try to load are accessed from the same domain (http://m-nlp.test/).

Weird facts:

• The live website on the production server is working in Firefox.
• m-nlp.test works in Chrome
• m-nlp.test works in incognito window in Firefox.

I cleared cache for m-nlp.test but it is still showing the same error.

What could cause it?

I run a blog on wordpress and while editing a blog post I tried to adjust the justify the paragraph but it not worked. I previously used chrome in which it worked, but in firefox it seems that its is not working.

Hi community,

I found I cannot open any local directory, like "file:///home/". Firefox keeps loading but shows a blank page. Actually I found I cannot open PDFs by Firefox first, and then I found I cannot open any directory. I think these two issues are related.

Does anyone have some idea about this issue? OS: Manjaro Linux Firefox: 80.0.1

Thanks.

Firefox has been severely lagging--specifically when switching between windows. For example, I could have one window running nice and fast, but then when I switch to another Firefox window, it is unresponsive for up to 10 seconds. That means no opening tabs, no scrolling, no loading pages, until it becomes responsive again. And this happens just about every time I switch from one Firefox window to another. It's a big problem because multiple windows are an inherent part of my workflow, so I can't wait 10 seconds every time I have to do something in another window.

Here's a very important piece of information: The problem does not happen in Safe Mode. However, Safe Mode is the only way to fix it. I've tried disabling hardware acceleration, disabling all extensions, refreshing FF (creating a new profile), reinstalling it, and the problem always comes back whenever I'm not in safe mode.

I've spent a lot of time on my own trying to solve this, with no luck. Of course, I'd be happy to post any troubleshooting information you may need to help me. Thank you!

Hey There,

whenever the window is inactive and i want to scroll the site (with a touchpad swipe) it instead navigates forward or backward. ONLY when the window is inactive. the behavior is the same with horizontal and vertical swipes. I've tried disabling the feature like described here (https://support.mozilla.org/en-US/questions/915174) but i had no luck with that.

i'm using firefox 78.2. on an opensuse 15 laptop. thought i might be an issue with that but with chromium i dont have that issue

thanks in advance.

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, I'm using both Linux and Windows on my computer. I've got problem with firefox sync, on Windows I'm using program like IDM and also use it's extension on Firefox. Meanwhile, on Linux this extension is useless. If I turned it off while on Linux, when I relogin to Windows, this extension also get turned off, I understand this is due to Firefox sync nature, but its so ineffective if I've got to turn it on and off while switching between OS.

Is there any workaround for this?

TIA

I downloaded and installed this package: firefox-81.0.tar.bz2 on Manjaro linux. If I click on Help/about, it updates. Does it update automatically, even if I don't open Help/about?

Earlier it was removed using style in userChrome.css file - " #PopupAutoCompleteRichResult richlistitem:first-of-type[actiontype="visiturl"] ", after update to 78.3 esr version this isn't working. I tried with deleted /home/.mozila folder (new profile) and with menu home ->top sites and search suggestions switched off (and also with and without userChrome.css file) so this is isn't the case. Thanks for help.

I perform Beta testing of GPS suites for several groups. My main interest is the CENTOS 8.2 operating system but I also service some Windows 10 laptops and two LINUX Mint20 machines. A GPS group in CANADA, https://webapp.geod.nrcan.gc.ca/geod/tools-outils/ppp.php operates an on-line processing service that I use and beta test for. They have a new engine about to be released but my main CEMTOS 8.2 machine is new and Fire fox is also going through updates.

The issue is that the I can uses Firefox and WINDOWS 10 okay on the old and new NRC-Canada applications. I can use old and new NRC-Canada software with Google Chrome satisfactorily but I cannot run either old or new NRC Canada applications with either LINUX MINT 20 firefox (Version 80.0 Firefox for Linux Mint-1.0) or the Extended Support Release 78.2 that is used for Mozilla Firerfox for CENTOS Linux redhat - 1.0

Appreciate help with this issue. With regards Peter (petermorgan@grapevine.net.au)

Despite the fact I have set Firefox in permanent private browsing, I routinely have to use the "Clear Data" command to remove cashed web content. I don't like stuff being dumped on my hard drive. Recently I have been unable to remove some of this cached web content, initially 32Kb, but now it is up to 752Kb - could this be malware?! How can I find out what it is and how can I remove it?

Hi,

I am trying to enable "Two-step Authentication" under the Manage Account page for my Firefox Account.

I've tried many authenticator / otp app on my android phone and my friend's android phone just to see, but none of them would work. It always says "Invalid two-step authentication code".

Has anyone been experiencing this? Does anyone have a lead on how to fix this?

Thank you!

I am running Debian 10 Linux and recently upgraded Firefox ESR to version 78.3.0 . I noticed that whenever I launch Firefox that the mouse pointer "spins" for up to 40 seconds after launch. This does not seem to affect usability but is visually unpleasant. I have done the following things: 1. Start in Safe Mode: The spinning mouse pointer is no longer spinning after launch. 2. Disabled all plugins and extension and launch Firefox: The pointer keeps spinning. 3. Downloaded Firefox 80 and launched: Pointer keeps spinning. 4. Changed home page to a blank screen: Pointer keeps spinning. 5. Uninstalled Firefox ESR and re-installed: Pointer keeps spinning. 6. Checked for viruses, trojans, and other malware: none found.

Interestingly, if I launch Firefox ESR from a terminal (eg "firefox-esr &") the spinning mouse pointer is not present. HMMMM! This is the command that is used in the desktop icon: /usr/lib/firefox-esr/firefox-esr %u . Is there a problem with that command. I may modify that command and see what happens. Feedback would be appreciated.

For example, this page mostly displays: https://en.wikipedia.org/wiki/Canada_lynx But items like the latin name does not (attached pic). Switching off the italics on the latin name causes it to display correctly.

Bolding text doesn't cause any issues.

My problem seems similar to this one: https://support.mozilla.org/en-US/questions/774797

However I can see Helvetica fonts just fine. I can cause the error when I switch it to italics. data:text/html,Helvetica Neue
<font face="Helvetica Neue" size="25">''abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ</font>

Any ideas on how to fix this? Thanks!
