I'm a web developer that setup a local environment under Linux Mint.

For some reason, Firefox Developer Edition (59.0b7 64-bit) cannot access sites on my localhost. The interesting thing is that Firefox Quantum 58.0.1 (64-bit) is showing these local sites perfectly fine. I've tested other browsers, including Konqueror and Lynx, and these work fine also.

I've setup my environment so that apache2 can serve pages from a 'wildcard' virtual host. Using symlinks, I can link my project files to another directory that functions as the web root. Thus:

/home/me/business/projects/client/index.html => /home/me/business/www/client/index.html

Navigating to http://client.dev brings up the page perfectly in Firefox 58, Konqueror, and Lynx.

However, Firefox Developer Edition, AND Google Chrome, both fail to load the page. The URL changes from http://client.dev to https://client.dev and throws this message:

"Unable to connect

Firefox can’t establish a connection to the server at client.dev."

I've played around with the about:config settings for Network.dns.* but nothing seems to help. Also, the apache logs do not produce anything useful.

Your input will be greatly appreciated.

Hello everyone.

I'm trying this again. Firefox crashed when I was logged in so I'm doing this in Chromiun now. I'm running Ubuntu 14.04 LTS 64 bit. Firefox is 56.0 64 bit. About one week ago, I received a notice about an Ubuntu update so I installed the update as always. After the update, on certain websites, they start to load then Firefox crashes. I was on this site eailer and typing this when I opened another tab to see what plugins were installed and it crashed. I was using Adblock, Noscripts and other plug-ins. I disabled each one, one at a time, and it still crashed. I then did a refresh on Firefox to have only the minimum orginal plug-ins installed. It still crashes. I then totally removed Firefox and deleted the /.mozilla directory and reinstalled. No change.

Now, The default plugins are: OpenH264 Video Codec provided by Cisco Systems, Inc & Shockwave Flash

    The default Extensions are: Safe Browsing Version 4 (temporary add-in) & Ubuntu Modifications Legacy

If I disable them each by hand, Firefox will still crash. If I disable them by restarting in safe mode, Firefox will work as normal. Here are at least two sites that won't load:

Hope this helps. Many thanks all. Mike

I had screen tearing and graphical glitches when browsing. [layers.acceleration.force-enabled = true] solved screen tearing, but I still had some graphical glitches from time to time which now seem to have been fixed with [layers.force-active = true].

Could this be a working configuration on the long term? Currently it is running like a charm...

I'm running Ubuntu 18.04 and had already turned off hardware acceleration and smooth scrolling without the desired results before trying the above-mentioned things. I also played around with the xorg.config.d settings of the OS...

Best regards Mike

I have not used my PC for three weeks and today I tried to log in to my Amazon account, but every time I tried to do the login it crashes, I also found it to crash in other websites like Reddit and the AMD Support Site. It is Firefox 58.0.1 64-bit in Ubuntu 16.04. I tried refreshing firefox and nothing, it also removed all extensions leaving only the default plug-ins: OpenH264 Video Codec provided by Cisco Systems, Inc & Shockwave Flash. If I disable them manually the websites will still crash. The only way Firefox will work normally is if I restart it in Safe Mode. I also tried installed the new 59 64-bit Beta version, but is causing the same problems.

The latest submitted crash reports are:

bp-5f7cae12-c429-4dd7-b794-8e4cf0180210 bp-8b31fc05-ede6-4d6c-8cd9-10efc0180210 bp-dd409298-45fb-43bb-8fa5-a02d00180210

Thanks for your help!

I'm using FireFox on ubuntu lts 16.04 as a kiosk making use of a very handy add-on. The system was looked down to prevent anyone for browsing anything but localhost. Now anyone can jump on my kiosk and browse / download anything they want. It is no way more secure than what it was.

Even after using the about:config options the updates still update!!!!!!!!!!!!!!

I will find a more appropriate browser option for the kiosk but for now I'd really like a way to stop the update short of shutting everything down.

I'm on Ubuntu 18.04, running Firefox 64.

I've tried importing directly through the wizard from chrome, and from chromium. I've tried importing through an html file (the html file itself is fine). Just literally nothing happens. I've tried running FF from console to see if there were any error messages, nope nothing.

Does this just not feature just not work at all?

Both firefox and thunderbird crash directly to the "Mozilla Crash Reporter" on startup. This also happens in safe mode.

So far I re-installed firefox through the package management (first completely removed it including configuration files, then installed it again). The profile created by the re-install is still completely empty, there is no data from the original profile and no plugins.

The button to automatically add troubleshooting information doesn't work for me (probably because I'm using chrome now), so I'll try to add relevant information. If anything is missing, please ask.

Firefox version: 55.0.2 Crash ID: bp-ced2e336-0d1a-40a4-9f45-e88b70170913 OS: fully updated Ubuntu 17.04 (64bit) Graphics: Intel HD 5500

This sounds more like an issue with Microsoft but it probably isn't because other browsers like Google Chrome doesn't have this issue. The domain "attachment.outlook.office.net" is unreachable/unresolvable in Firefox (58 and earlier versions) in Ubuntu 17.10 64-bit. All the attachments that are delivered with Outlook are hosted in this domain and whenever I check Outlook e-mails using Firefox in Ubuntu the attachments are unavailable. They are there in the e-mails, sort of, but they are shown like shortcuts that don't lead to anything.

How do I make the toolbars smaller? Since upgrading to the latest version, they are twice as tall as they used to be. The text in them is still a reasonable size but the toolbars take up twice the vertical space they used to. This has nothing to do with the size of the page I'm viewing so Ctrl+ or Ctgrl- has no effect.

Thanks for any help. Attached is a screen shot showing the wasted space at the top of my screen with the new toolbars.

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.

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

I only have this problem in Mint 18.2. I go to the link http://wamc.org/topic/food-friday I press play. A pop up appears briefly at the bottom left with this address https://cpa.ds.npr.org/wamc/audio/2017/09/vp-ARCHIVE-9-1-17.mp3 but then disappears and there is no audio. If I right click on the first link and choose open link in new tab it opens the 2nd link in a new tab and I get audio. I have several Linux versions and this only happens that I've seen in Mint 18.2. Also it doesn't happen on the same device with Chromium or Midori or Opera only Firefox. Not a big deal but odd I think.
