Firefox Support Forum

My Firefox installation on Ubuntu 20.04 does not load or render any page, nothing happens when I enter an address.

I have already rebooted multiple times, purged Firefox through aptitude, deleted all files related to Firefox (profiles, the complete .mozilla folder in home, everything else) and reinstalled as suggested in various support platforms. I have started Firefox in safe mode as well.

As far as I can tell the problem started after I used "another" Firefox through my universities Citrix service to be able to access their library catalogue. I had to symbolically link all of the files in the Firefox certificate folder to that of the Citrix client for that client to work, although I've since removed those links as well and it did nothing.

I am really pulling my hairs over this as Firefox is heavily integrated in my workflow and I don't want to switch to Chrome but I also don't want to completely reinstall my laptop as that would mean completely setting up my work environment again too.

Firefox 87.0 (64-bit) on Ubuntu 20.10 is currently unusable as it won't open anything.

• Firefox opens with no page loaded.
• Clicking the single "getting started" bookmark does nothing.
• Entering a search term in the address bar and pressing 'enter' changes the url in the address bar but nothing is loaded and the page remains blank. There is no indication that anything is loading.
• Entering a url, such as "www.youtube.com", and pressing "enter" does nothing. There is no indication that anything is loading.
• Opening the menu by clicking on the burger icon, then on "preferences" does nothing except make the menu disappear (same with most of the options in the menu).

In the browser console I see some errors and no request info (see screenshot).

I've tried `sudo apt purge firefox` then installing again, which didn't help. The problem started with ubuntu 20.04 (I only updated to 20.10 to see if it might resolve this problem).

I've tried the "refresh firefox" option, starting in safe mode, and clearing the startup cache, which didn't help.

Any suggestions would be much appreciated.

This all started after last firefox upgrade/update a few weeks ago so installed gmail chrome which works fine.

Even reistalled OS & then worked ok till firefox did it’s own updae.

I have deleted & reinstalled a couple of times but same problem.

I use Linux Ubuntu 20.04.2LTS on an older (+/- 5 year) HP Pro 3130 MT a 64 bit machine. Chuck

First of all, this doesn't affect the Windows version, only the Linux version (didn't test on OSX). The problem is as follows: 1. Firefox installs an update in the background while still in use. 2. I open a new tab. 3. That's it. After an update finishes downloading, new tabs refuse to open, some citing a crash (if opened by active tabs, such as YouTube), most stating the browser needs to restart. It is not a networking problem, since already active tabs function normally, even YouTube playlists function as intended (despite the fact that they nominally refresh the entire page); and, as mentioned, the browser itself says it needs to restart. Q1: Is this intended behaviour? If so, Q2a: what purpose does it serve? If not, Q2b: what causes it? Additionally, after an update, Firefox (again, only for Linux) has rendering problems when first booted up, causing tiling, and needing Alt+f4 to close. I may revisit this issue later in a separate thread.

In linux (ubuntu) I have some serious issue when I open firefox the tabs are going to white and I don't see any buttons and website. But When I Hovering the firefox in mini window i can see browser but in full screen there is only white screen as you can see in image I attached.

I'm running version v92.0 (64) on ubuntu 21.04. Firefox would crash upon opening when signed in. It would stay active enough for me to disable the extensions & themes. After doing that it still crashed. I tried going into Troubleshooting mode and it would still crash. I went into Troubleshooting mode and did a refresh. It was still crashing. Finally I signed out of my mozilla sync account and the browser has stayed active long enough for me to type this report.

I've submitted all crash reports in about:crashes, and I'm not really sure what to do next.

Perhaps a local version of the Mozilla Sync profile has been corrupted? if so, is there a way to remove it and pull down the "sync"ed version from Mozilla's servers? What if the version on Mozilla's server's has been corrupted? should I back up the local profile (wherever it is) before removing?

I hope I've given enough information. Please let me know if you need further, more specific information.

On certain websites this "Geckomain" process destroys my CPU to 100% and maxes my network traffic with more upload traffic than download, using a lot of my data and bandwidth etc. This is a major concern because I have to pay for my data, it's not unlimited. If left open this process will consume more than 1.5gb of RAM while nothing functions. The only way to stop it is to leave the website. I have to use these websites for my job, so I can't just avoid them. I need a resolution ASAP. Thank you.

When I click the fullscreen button on a video, such as YouTube or Netflix, I find that upon exiting the fullscreen video and going back to normal screen, Firefox's window size is now maximized, when it was a smaller window before clicking the fullscreen button.

I am running Ubuntu 21.10 and I don't recall having the issue in previous versions.

Hello,

Recently, I updated ubuntu to the latest version, and had set Firefox as my primary browser (as I normally did).

I, however, could no longer access to the local hidden directories, i.e.: .local, etc., with this version. I even tried to disable Firefox sandbox security, security.sandbox.content.level = 0, and changed chown/chmod to the lowest levels, but those didn't help.

The issue can be repeated via the URL in Firefox as followed:

file:///home/y2021x/.local

or any other hidden directory. I could open these files/directories in the older versions of Firefox.

Am I overlooking something? I appreciate very much if you could help me find out the solution to this problem. Thank you very much.

For last fiew days I get a double prompt for primary password when I start a firefox session (on linux ubuntu 20.04). I'm worried if this is a bug or a troyan.

What can I do to find out?

I'm struggling with firefox crashing every few days or so. Unfortunately, pretty often there is no crash report. Is there a way I can sanely get to the bottom of this?

It happens to me more often with Cisco Webex than other scenarios, but there are also completely unrelated crashes.

This is Ubuntu 20.04 and standard firefox package installation. I haven't yet turned off the extensions:

 feedbro
 gnome shell integration
 stylus
 uBlock origin

I hesitate to disable them since most are important to my work.

Any help is appreciated.

Loading a web page stopped in the middle. I have checked my internet connection: OK. After that no one web pages was opened in the firefox browser. I have opened Chrome and everything worked well , web pages has been opened.

I have purge firefox installation (apt purge firefox) and installed again. Not helped. I have switched off all the extensions. Not helped.

I have read and followed the things in the article: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can Nothing helped.

I am using Ubuntu (Ubuntu 20.04.3 LTS) any idea?

For quite a while I am using Firefox and had no issues, but recently, with new version , I am constantly facing two issues 1. the initial load of a page takes more then 30 seconds , sometimes 1 minute, but after the first page has been loaded if I open another page , it will be as usual 2. Completely random and without any sign of slowing down the OS - the OS freezes - nothing works at all and I have to restart it using the power button. ( and this happens when Firefox is open so I doubt Firefox)

version Firefox Browser 91.0.2 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

I am having issues with opening link for external applications. The application can be What'sApp or Zoom or Slack and when trying to open an external app I get a windows that ask for me to select the application to open the link.. When doing this the only option have I have is System Handler and Choose Application.. Neither option is helpful.. This did not happen with firefox packaged with .deb .. I am assuming that this deal with snap sandbox security.. I later read an article

I did a little reading and came across a link https://ubuntu.com/blog/how-to-snap-introducing-classic-confinement

Which instructed on how to create a snap with --classic confinement.. I am not sure if this will resolve the issue that I am having .. But I didn't find that I could install firefox snap with the --classic option.. I am not that familiar with snaps so I could be completely off but wanted to know if someone could look into it..

I would like to add an image but it doesn't seem like firefox will allow me to on this page. (Browse is not opening a window) Also copy and paste didn't work

I am using KDE Ubuntu Linux OS on desktop CPU with Firefox browser.

When I went to sign in to a website. After I entered the user name and password the next step should be that requires a Google 2FA authentication code but the website goes blank. I refreshed site. Still a blank webpage.

The website will open correctly as expected using my Android cell phone using Firefox browser. Which is also where I have the Google Authentication app installed.

I had to use Brave to open the website. I am told by others Google Chrome will also work but I try to avoid both these browsers.

I have not added the 2FA sign in to Firefox main sign in yet. I intend to switch over to a Yubikey 2fa in the near future.

Any ideas?

Firefox seems to be blocking some element required for logging in to Dropbox. Any attempt to log in to Dropbox results in this message:

Your browser appears to be blocking dropboxcaptcha.com, which is required for authentication. To resolve this issue, please update any anti-virus or ad-blocking software settings to allow connections to dropboxcaptcha.com.

I have found the issue referenced [https://support.mozilla.org/en-US/que.../1146181|once]before on this forum, and that solution does not resolve the matter: restarting Firefox in safe mode has absolutely no effect on this, and the problem manifests identically in whether safe-mode or not.

Details:

I am on Linux 64-bit, running Ubuntu 20.04, with Firefox provided by that distro's repo.

I am currently using Ubuntu Jammy Jellyfish (development branch) on a Dell XPS laptop 11th Gen Intel Corei7-1165G7 @ 2.80GHz × 8 cores and 16 GB of RAM and I am having issues with Firefox 98.0.2 (64 bit) Snap package for Ubuntu canonical-002-1.0. The issue is that the drag and drop functionality for bookmarks is not working anymore.

Firefox will only open in Safe mode, previously it was working but now it's not.

I have Ubuntu 22.04 Firefox version 99.0.1 (64-bit)

When I try to open it in command line, it's also only opening in safe mode but I do also get some error messages that I've included below.

So what does all this stuff below from the command line actually mean? And how do I fix it?
