Dear mozilla community,

I cannot get firefox to start, and I need help to troubleshoot this. What I already did:

• remove and reinstall (apt)
• rename ~/.mozilla to trigger recreation
• start using the command line
• start in safe mode

The only symptoms are <defunct> processes (see screenshot).

I need more information to find out what went wrong. Where can I find this?

Details

• apt
• firefox_78.0+build2-0ubuntu0.16.04.1~mt1_amd64.deb
• Linux Mint 18.3 Sylvia

I've installed Firefox Multi-Account containers but I don't have either the shortcut in the upper right corner, nor the option to open a link in a new container (see screenshots attached). I've removed and added the add-on several times as well as doing clean installs of Firefox. Nothing is allowing me to use containers, though it shows installed.

I have made no changes to the default preferences (wanted to get this working before tweaking) and the only other add-ons I have are NoScript and YouTube Flash Player by Maxime RF. Removing either or both of those has no impact on my problem, as far as I can tell. Enable Container Tabs is checked (and grayed out) in Preferences, as the add-on requires it.

I'm on Firefox 77.0.1 (64bit) Clean install of pop!_OS 20.04 LTS

This is immensely frustrating, so any help would be appreciated!

Hello, all...

I'm running Solus 4.1 with the 5.6.18-155 kernel on my Asus UX330UAR and Firefox Nightly 79.0a1 (2020-06-26) (64-bit). Currently, I used Android Messages for Web via a "webapp" in Brave and am provided a "desktop icon" for that window; however, I'd much rather use my default Firefox and just discovered the "browser.ssb.enabled" setting.

The "trouble" is doing so does not provide any icon to launch by itself; that is, I must be already in Firefox to use the "App Mode."

Any ideas on how to accomplish this dream?

Thanks for any ideas!

Hello all,

I have a very strange problem and I need help like anything.

My system is Mint 19.2 based on Ubuntu 18.04. I was using a Ricoh Printer model SP 111. I was able to print from this printer using any app like LibreOffice or Adobe Reader. But intermittently a problem occur. Whenever I send a print from any app to this printer this only pass a single blank page. The strange thing is that during the problem too I am able to print any document from firefox. Though i am able to print only 2-3 pages correctly from firefox. If i give more than 4-5 pages it may be passing only second page to printer.

Can anyone please help me short out this problem so that I be able to print from other applications too.

One thing may help me if I know how firefox send prints to this printer and what method firefox use to send print to this printer.

I am using https://github.com/madlynx/ricoh-sp100 community driver for this printer Ricoh SP 111.

Using Firefox 77.0.1 on Linux. How do I create|add a new toolbar? Searches here and on Google show massive hits but none I can find to explain. It used to be available under the toolbar button on the customize page.

Hi,

Show me how to find the bookmark manager

I've seen this question from two years ago, but the answer is not valid (any more).

I had several machines with different purposes and when I got a Firefox account, I signed them all in. Now the bookmarks are chaotic, and I want to combine them in a more rational way. I need a real manager that allows me to do this. I'm sure there is one, but I cannot find it.

Currently FF 77.0.1, according to help.

I'm using Firefox Beta on a slow laptop in Linux -so, manually changing videos to 360p from the cog works to make them play smoothly. The facebook SD Only setting in https://www.facebook.com/settings?tab=videos doesn't really work -only in a few videos. If anyone knows of an extension that handles this on latest Firefox Beta let me know. Thank you.

Hi all, I just changed to Firefox ESR since some websites are not being correctly displayed in the "normal" firefox, this version works much better but I don't like that when I click in the address bar I have to double-click to select the URL, not like in the "normal" firefox, so, I just want to know if there is a way to change to when I click it automatically the URL gets selected. Thanks!

I am using Firefox Extended Support Release 68.10.0esr (64-bit) in MX Linux 19.2

I have been using firefox for years and am very happy with it. I have a Dell optiplex 7010 desktop. I am running Ubuntu 18.04.4 LTS. I do not have a firewall turned on. Apparently, my desktop browser was updated to Firefox 78.0.1 (64-bit) on 7-1-2020. Since that time, I have been unable to access any websites from Firefox including mozilla.org. I am connected through WiFi. After downloading the Opera browser I have been able to access any website with no problems. I read community troubleshooting on this issue and tried various fixes including turning off IPv6. I read the community article about turning off my personal firewall. I was unaware of using any firewall so I installed Gufw Firewall 18.04.0. Running this program shows my firewall status is "OFF". I checked my AT&T modem and could not find any firewall settings that specifically mentioned Firefox. I would like to continue using Firefox since I use it on my phone and laptop also use it.

My laptop is a Dell Vostro 1520 running Ubuntu 18.04.2 LTS 64 bit. It also accesses the internet through the same WiFi. It currently has no problems loading web sites with Firefox version 78.0.1

Please help.

In my browser whenever I am opening non secure sites that are only like http://example.com it redirects to https://example.com and display the error. "Warning: Potential Security Risk Ahead" error. I could not know how to fix this error. This is happening all of a sudden. I could not find a way to fix this error.

I am in Fedora 32 with Gnome and Wayland…when i want to change the properties of an bookmark in the sidebar, the context-menu doesn't work. Did anyone notice the problem or is there an bug report? (i do not know where i have to look at :/ )

On some sites and a NextCloud installation, I suddenly cannot click on some links that report following error in the console: Uncaught Error: Permission denied to access property "apply"

   jQuery 7
   clear searchprovider.js:292
   attach merged-index.js:11661
   jQuery 8
   _setCurrentDir merged-index.js:5820
   changeDirectory merged-index.js:5752
   actionHandler merged-index.js:3432
   action merged-index.js:2894
   _onClickFile merged-index.js:4757
   Underscore 3
   jQuery 2
       dispatch
       handle

I've checked and disabled add-ons to see if these were blocking somehow, but no result. It worked fine before, so my suspicion is something changed in FF78? Thanks!

Today firsfox just stopped connecting to a wss websocket server. It has always worked fine before today and still works in Chrome.

What happened???

Port is open. Connect when running websocket.org/echo.html in chrome but not in firefox

I had a thing happen that surprised me:

1. Open private window
2. Download a file (slow enough to give time for testing)
3. Open "Downloads" (becomes a tab in private mode, filling the main browser window)
4. Close any other private tabs
5. Close "Downloads" tab
6. Downloads are terminated without query

My expectation was that the user would be queried in some way.

Hello,

Since about 3 weeks, Firefox hang on certain websites while trying to load them, when un-ticking all "Firefox Home Content" items. When those things are ticked, everything is fine. Wasn't happening before. Often a gray geared wheel appear and at other times only the "tab text" appear, please see the attached screen shot. I'm able to click on "File Edit View...", the items present on the bookmark toolbar, "Refresh", "Home" but the action is executed only when Firefox un-hang. I'd already get a look at Firefox help tutorials but there was nothing about "The "Firefox Home Content" can cause Firefox to hang".

It take me about 10 minutes to load this current page. "Firefox Home Content" are not ticked right now.

Thanks,

Guillaume

Hi All

some pages like this one are wide enough to have a horizontal left/right scroll bar.

https://trello.com/b/3OtE8BCR/brizy-wordpress-public-roadmap

If I'm lucky, when I want scroll left or right, the cursor is on a piece of HTML where it can move when I use the left or right arrow keys. However often, the cursor isn't available or the right place.

Is there a key or key combo where I can shift the web page left or right in the FF window? I often find it difficult to use the horizontal scrollbar with the mouse.
