Firefox supportforum

The profile folder on the new installation is to be replaced with that from the old. So far so good, I've copied the profile folder from Windows and now want to exchange it for the profile folder on the new Ubuntu computer. Problem is that this is the very latest Ubuntu version (only a few weeks old) and there IS no profiles folder in Firefox!

What there is, is a profiles.ini file but I am reluctant to put it in there because it does not appear to have anything to do with the contents of the ex-windows profile folder.

There is an option to create a new folder but I'm not at all sure what this would do.

Hope you can help

Good day, there is such a question, is it planned to release (or port) a Firefox browser for Ubuntu Touch? Unfortunately, the only browser available is "Morph", and it does not meet the requirements of many UT users. I'd love to see your browser on this platform, as convenient as for android and ios. Regards.

Hello, I always download mp3 files inside webs using "Save as" and ".mp3" method. Sometimes I had to explicitly save filename with ".mp3" extension to force audio download. However trying to download an audio no matter what format I write in file always download only webpage as .html never as .mp3. Looking at sourcecode (image attached) I found a detail containing "chrome" in webpage. Later, I tried downloading with Chromium at it worked properly. Does anyone know how to download this from Firefox?

Thanks in advance for your help. P.D. I am using Firefox 84.0.2 (64-bit) for Ubuntu canonical - 1.0.

After installing Ubuntu 20.04 LTS Clicking on Firefox or Thunderbird it hangs the computer and have to switch off the computer on main switch. Reinstall Mozilla once but no difference still hangs Ubuntu. Need help on this one Thank you

When video/audio starts playing on a browser, the tab title displays 'playing' text. This additional line resizes the window height and causes the tab content to resize too. For example youtube starts resizing video window height and width - and this is very annoying. How do I remove 'playing' text from tab FOREVER?

While using Ubuntu 18.04.03 LTS and FF 71 When I go to www.Pluto.tv a free TV site and leave it running for about 40 minutes or more the message " a script on this page may be busy" this always happens both on Ubuntu and another Linux system. this problem does not occur on my Mac OS. the problem when left alone the CPU goes very high on the Linux system preventing any usefull usage of FF until it is closed and reopened.

The message that pops up suggests FF is interuppting something incorrectly. Anyone with a suggestion to stop this problem? Keeping in mind FF plays with no flawas for more than 40 minutes

Lately I've noticed that I cannot log on to the Xfinity.com website. The home page displays and the login screen allows entry of login ID, but then the screen blacks out and shows only 3 dots that move slightly to show something is happening. Eventually, the site times out and goes back to the login screen.

This happens on my laptop. It is running Firefox version 86 under Ubuntu Linux. I have tried this on another computer running Windows 10 and get the same result, unless I use Microsoft's browser. Firefox loads the Xfinity site correctly on my Android phone, version 86.1.1

Any help would be greatly appreciated

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.

Problem: FIrefox suddenly quit working. Firefox refuses to load anything including local, external, and firefox config pages. When attempting to go to a webpage or config page by pressing the enter button nothing happens and the page is entirely blank. The developer console does not open. After about 2 minutes of not doing anything, it crashes. Issue persists past re-installs. I am unable to submit a bug report as normal(I only have pending crash reports), as when I attempted, it said "something unexpected happened" and then the bug report itself crashes.

Chrome works normally as expected.

Troubleshooting steps taken:

• Refresh and safe mode
• Launched in incognito
• apt-get purge
• Removing profile
• removing .mozilla, .adobe, .macromedia, /etc/firefox, firefox-extensions, .cache
• installing nightly, beta, reinstalled multiple times.

Current workaround: Using chrome

Greetings, I am trying to fill out a PDF form using Firefox's built in PDF viewer and form editor. I'm running Linux (Ubuntu) with Firefox 84. I am able to successfully view and "Open" the PDF within the browser, and even edit the text properly. However, upon saving or printing, the text gets rendered with a massive font size nullifying the ability to edit in browser. I've been trying to find some online resources without success, and can't seem to find others reporting a similar case.

I've disabled all extensions and restarted Firefox, but did not notice any change in behavior. Any tips for debugging? Attached are two pics of the PDF form while editing, and then the rendered PDF after saving.

Problem appeared in the last few days so I assume it is due to the recent update - 91.0.2

Clicking the Menu button (3 bars), the button goes grey but the application menu does not appear. If I move the mouse around, I see flashes of the menu but that's all. A graphics problem?

I have also found that copying and pasting is inconsistent. Sometimes it works sometimes it doesn't. Sometimes it flashes. No problem in Thunderbird or other applications.

I have tried reinstalling Firefox - no difference I have tried Firefox in Safe Mode - no difference

In my settings I have Firefox set to open PDFs using the app 'okular' (see screenshot). In my file browser, PDFs open in 'Okular' (see screenshot). However, when I click a pdf in the Firefox downloads pane, it opens with 'GNU Image Manipulation Program'. Why is this, and how can I change it to 'Okular'?

I'm running latest version of Kubuntu, with current updates.

Version 92.0 (64 bit) Ubuntu: 18.04, 20.04

For a couple of months, I have not been able to resize the FF window. Consequently, I abandoned FF for Chrome. I've just upgraded my os to Ubuntu 20.04 (from 18.04) so I thought I'd try FF again. The problem persists.

Minimize/Maximize work fine, but when non-maximized, the resize "handles" don't show up (see attached image). I've tried safe-mode, as suggested by some previous post, but it hasn't helped.

Hello,

Since a while now, Firefox is really slox on my computer. Here is what I use :

• Ubuntu 20.04.02 (an LTS version)
• Intel i5-8250u & 16Go of RAM
• Firefox 84.0.2 (64 bits)

I experience, as mentioned, heavy slowness while loading and switching between pages, but also when I want to select DOM elements like links or buttons. Firefox actually freezes for sometimes, I guess depending on how long it has been opened, but I am really not sure. When switching from one page to another I even get a loading circle, even in private mode. And it does matter if I am on a "heavy/complex" page like Facebook or Youtube, or "simpler/lighter" pages like Wikipedia or some random blog.

What I tried to solve the issue :

• used Firefox in safe mode
• cleaned Firefox cache
• used Firefox integrated repair mode

Yet, even though I got to admit Firefox did not have freezes after a repair operation or cache was cleaned for a few while, slowness always come back. I cannot afford to do that everyday.

Is there a durable solution to this issue ? Thanks, Lou.

This question was asked 6 months ago and I have the same problem.

Running Ubuntu Mate 21.04 (metacity), FF 91.0.2 (64-bit). I have it set up with two different profiles, with separate menu entries for each using "firefox -P [PROFILE NAME] -no-remote %u". One of them is set to always use private browsing mode and I use that profile as my default app in mate.

If if set chrome as my default browser, I can open links from other apps without a problem regardless of chrome being already running or not.

When I set FF as default, whenever it is already open and I try to open a link, I get a "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile." error.

I've seen some comments about similar issues with wayland and tried setting MOZ_DBUS_REMOTE and even MOZ_ENABLE_WAYLAND to 1.

Can you help me?

Fresh snap install of Firefox. No addons or anything. Right out of the box. I cannot drag a URL and pin it into a folder - it does not produce that usual line indicating where the bookmark will be placed. Show your Bookmarks displayed on bookmarks.

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 am using Firefox with Ubuntu 16.04. I run Ubuntu from Virtualbox in Mac host. Firefox is freezing frequently, at least once every day. System is completely frozen. The mouse pointer is moving, but no responses from mouse click. Cannot point out to any specific websites. Sometimes it just freezes while using my university email and Lms together. Really inconvenient. I really do not want to switch from firefox to chrome. So this is my last try before the switch. I tried solutions that I found online. I uninstalled and reinstalled firefox. Tried installing through Ubuntu Snap and then reinstall through command line. Tried refreshing firefox. But all ended up in the same result Any help would be appreciated
