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

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

Mozilla has an agreement with Yandex in my region. I understand the need for a sponsor, but I am very unhappy with my preferred search engine being changed to Yandex after each Firefox update without my consent or knowledge.

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

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.

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.

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

Hi I mean one of these (image below) ? The goal is to prevent reloading the tabs among ones that were openned in a previous session and I don't need anymore (and by the way FF won't update my history as not needed) - Even if I'd didn't use "Startup/Restore last session", this would be a great feature to be able to close with right-click any tabs whose names in shown in the drop list when so many tabs are openned that the last ones can't fit in the width of the window (actually tabs "toolbar"). Thanks you for this great browser. I asked this 2 years ago if there's a way.

Random today, firefox 69.0 (standard firefox from the Ubuntu repo) on Pop!_OS 19.04 (running KDE plasma) started randomly becoming super unresponsive. I would type and it would then proceed to freeze for a second, then choppily spit out my characters one by one. This happened even after wiping the .mozilla folder, after purging configurations, after refreshing firefox and after launching it in safe mode. Any idea as to why this is happening and how to fix it?

Many preferences don't sync, and it is sooo annoying to change them again every time I log in into a new Firefox instance. Can you please get more options to sync, such as the ones mentioned in the title?

Related to this, extensions that are installed not for the first time should not open new tabs (or at least an option should exist for this). And the preferences from the extensions themselves should also be synced.

I'm using firefox in linux for selenium test automation. Some of my automation tests need a sysproxy (provided by my company) to access internet. These prefs are set in my test

"network.proxy.type": 1, "network.proxy.http": "company.proxy.com", "network.proxy.http_port": 8080

When firefox launches up, a prompt dialog is always shown asking for credentials for the proxy. I've added company .pem in path ~/.mozilla/certificates and these .pem are loaded correctly in firefox.

Is there a way to disable the user prompt dialog?

I am using Ubuntu 18.04 LTS 32 Bit. It came with a per-installed Firefox browser which updated itself to version 66. When I want to print something the page setup button does not provide options to set the page margins. Hence the margins are permanently set to one inch on all sides. I sometimes need to print documents which need extremely small margins, e.g., 0.2 inches on all sides. The only options available in the Page Setup dialogue box are: Format For, Paper Size, and Orientation. On the other hand, clicking the Print button provides several tabs, including one named 'Page Setup', but this one does not provide margin settings either. Another tab here named 'Options' provides the options to leave the header and footer blank but no options of setting the margins. Any help would be welcome. Thank you.
