In my application Im updating the img src value every 5 seconds. But sometimes images are flashing or blinking only in fire fox. I tried disable hardware acceleration, still same. Please help.

Firefox 46.01 under Ubuntu 16.04 In this website: https://www.onlinemictest.com/webcam-test Or any other website that uses the webcam I get the error message: Camera not authorized. Please check your media permissions settings. Permissions are ok (set to allow after prompted), but still no video - cheesse works ok and properly shows video. The website asks for permission to share the camera as expected, and it is set to ALLOW. Would appreciate your help. Best, Marcelo

I've been having major problems with cursor control by mouse wheel and keyboard on the Ubuntu install. I've improved it by alterations in about:config, but it's still not right.

I have this install on Windoze Vista that works perfectly, through no fault of my own, just as installed.

Can I simply copy the file from the Windows Vista install to the Ubuntu install to fix it?

If so, what is the file name (about:config ?), and where is it located?

Thanks!

I'm getting big confusion in 46.0.1 in Ubuntu (NOT the system I'm on right now. Scrolling is inconsistent and frustrating.

=======

MOUSE WHEEL SCROLLING - I've got scrolling by mouse wheel working as I want it on normal pages like Facebook, Google result pages, etc. (one rotation click = one page)

However, in, for lack of a better name, "list" pages, like my webmail AOL pages or the about:config pages, the scrolling is too short. On the webmail page, it's two display lines only. On about:config, it's three lines.

i want everything at one full page.

==

The keyboard keys are much more goofy.

ARROW KEYS

- - Facebook, etc. - As I want them at 3 lines
- -"List" pages - OK at one line at a time

=

PAGE UP / DOWN

- - fine at one page on Facebook, Google results, etc.
- -"List" pages - First key press (either one) gets me zero or one line, depending on what test page I'm using. Second gets about one page, third = 1 page, Fourth = zero to one line, fifth = one page, sixth = 1 page, seventh = 1 line, and so on.

"Page Up / Down" should get one full page every time, either direction.

- - On the "List" pages only, on the times when full page movement happens, it moves about the full page, and then sometimes jumps another couple lines or so down. - - Also, page up / down won't work multiple times (repeat) when it's held down for several pages worth. Maybe keyboard repeat is out pacing FireFox and confusing it?

How can I exorcise the spooks from this ?!?

Thanks!

I've created a website in php5. During development I used Firefox 46.0.1 on Ubuntu 14.04LTS. The session variables are nicely stored en can be read.

Now I'm starting to test on different browsers, my Windows 10 pc with Firefox 46.0.1 doesn't store the session variables. Chrome and Edge do store the session variables on my Windows 10 pc. Also on a win 8.1 pc with Firefox 46.0.1 the session variables are not stored.

Any idea what could be the cause?

What I typically do in a php script:

?>

In order to reload the page, I use javascript. "location.reload();" When commenting that line out and refresh the page, the session variables are available.

Any idea on how to solve this issue?

Firefox crashed and now it won't let me restore my previous session. Other guides said to restore it with a backup file, but that was on windows, and this happened on ubuntu 16.04 and I don't know where that would be there. If it helps you any, I just upgraded my motherboard, cpu, and ram a few days ago. I'm sending this question from a separate windows partition.

Every time I start Firefox it starts displaying a "You should restart firefox now to install updates" message to the left of the location bar. I checked all plugins, all addons - nothing is updated or needs updating.

OS is Ubuntu and Firefox is installed from a tar.gz When I use Firefox version from repos, I don't see such an error.

Hi there,

This issue reports to a desktop computer with 8 CPUs and 24 Gb of RAM, which pretty much puts aside any resource constraints. Ever since Firefox was updated to version 49 the browsing experience has become increasingly difficult with a relevant lag on pretty much every task: . opening a new tab . loading/reloading a web page . scrolling down a web page . entering text (takes almost 1 second for a character to appear) . deleting text . using menus (e.g. takes about 1 second for the context menu highlight to move up/down to the next item) . great reduction in frame rate when playing videos (actually, I no longer play video on Firefox 49)

I have tried various things to stop the lagging: . restart Firefox . disable/uninstall extensions (now down to just 4) . disable/uninstall plugins (now down to just 3) . update plugins

But the lagging prevails.

I use pretty much the same web pages as I did with previous Firefox versions, but only with version 49 am I experience this lagging.

Thank you.

I have three Windows machines and one Linux Ubuntu 16.04 LTS machine, which by the way runs W7 inside on an emulator. Is it possible to use the profile from my main computer in Ubuntu machine? I assume I can use it in the emulated W7 on that machine, it is W7. Thanks, Fred

Hello. Bug on Ubuntu? When I enter text in Firefox the mouse cursor stays visible and active. Another browsers don't do this. It is normal behavior?

Firefox 49.0.2 Ubuntu 16.04

Recently starting up Firefox im welcomed with a "Restore session" screen but when i click restore all it does is open empty tabs, two days ago i managed to restore the tabs by going back and forth between "Restore session" screen and empty tabs but today the "Restore session" screen was empty. can i restore my tabs or what is going on?

also can i note that Mozilla becoming less and less stable by the update? not just tab wise

On fireox 54 on linux mint 18.1 because of error F7363-1260 I can't use netflix, on netflix help page they told me that the error is caused by an extension or a plug in on firefox, but I haven't got any extensions and same with plugins, how can I do?

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.

So I am not completely nubcakes, so i have ran apt to get update builds and build-trees. Still doesn't fix things. It mostly crashes with Facebook and Youtube. But that is mostly what I use FF for. It has even crashed repeatedly on just about:restoresession. I think it is a video problem. I have ubuntu 16.04 LTS but everything is up to date. Doesn't matter what is loaded or not, see about crashing just on restore session with a single tab!

The problem still happens in safe-mode, so there is that checked out. The reports don't appear to have much in common.

Thanks,

These are the crash reports just from the last month:

My network is using proxy to get connected to internet. User authenticate to proxy using username and password from Active Directory. I am unable to authenticate to proxy, it keep asking password even I have supplied the correct password. I tested the condition using other browser and it works with Chromium. How should I connect to the proxy ?

Attached the pop-up

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.

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

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
