FIREFOX MOZILLA LINUX: Firefox would Not Open...I did a REFRESH 3 TIMES...it read: Successful...I then went to Firefox Browser...to Open Firefox...and 3 times it read: Successful...But i still can NOT open Firefox.. Please Help thanks, rm

I'm a Linux (archlinux) user. After the update to FF73 I cannot play Netflix movies. I can log in, see the homepage, choose a movie and then I tries for awhile to run the movie. After a while it fails with error: F7702-1290. It suggest to check I have the latest version of Firefox, which of course, I do. Any Ideas to solve the problem.

Background: I just had to rebuild my Linux system partition from backup.

After doing this I discovered that although most websites behave perfectly with Firefox, there is one website which now never appears in the history though I have visited the pages with no problem.

This is a problem because I use the change in color of links to the website to keep track of which pages I have visited. I have looked to see if Firefox has a list of sites which are not tracked but have been unable to find it.

PS, after the restore all my old history was restored including visits to the website which is now causing a problem.

Firefox 76.0 64 Bit for Linux Mint 1.0 Mint 19 Cinnamon3.8.9

How can I prevent a single tab from closing?

I would like to prevent the keystroke Ctrl W from closing the active tab.

My understanding is that it is impossible to change keybindings in Firefox.

I thought an alternative might be to set Firefox to warn before closing a tab.

I had no luck in finding such an option.

Is there such an option?

If not, any other ideas?

I'm trying to open just one tab when I open Mozilla browser. I can't figure out why multiple tabs keep coming up.

Many Thanks (in advance) for your help.

I am looking to a way to open specific bookmarks open as pinned tab. If there is no way, accept this as a feature request which can add an option in bookmark properties to enable this bookmark open as pinned tab instead normal tab. Thanks.

We currently would like to upgrade our centrally installed Firefox ESR version and would like users to keep their settings and be disrupted minimally. Specifically we would like to upgrade from 68.4.2 to the current 68.8.

I am aware that as of Firefox 67 a dedicated profile version is used for each Firefox version (https://support.mozilla.org/en-US/kb/dedicated-profiles-firefox-installation).

I had assumed that as it is only a minor upgrade of the same ESR version a new profile would not be necessary, however it creates a new empty profile by default.

The suggested solution to use Firefox Sync is not an option as creating Firefox Sync accounts for all our users would even be more overhead.

Is it indended behaviour that new profiles are created for the same ESR (major) version? Is there a simple way to migrate existing profiles?

Thanks.

Hi,

Since months I'm struggling with this issue but today I became unable to bear any more.

Many websites works fine with Chrome while don't with Firefox because of iframe issue. As shown in this link you can read the story fine under Chrome while sucks with Firefox so I wonder:

How can I bypass this issue? Is there some kind of CSS manipulation for run this kind of content fine (I run some websites locally so Firefox always sucks with iframe)?

NOTE: See the attached please

Well, I guess when I wrote the above I was expecting whatever help you might be able to give. Obviously, I'd like the problem fixed; how its done is up to someone who understands the problem and knows a whole lot more about these things than I do, and can communicate the procedure to me. (For some reason the Subject box above says that I've entered 574 characters EVEN AFTER I'VE DELETED MORE THAN HALF OF IT)

I recently installed some linux distributions on the raspberry pi 4 including firefox. In contrast to the same os/firefox combination running on my (10 years old) laptop pc, no widevine Content Decryption Module (CDM) addon seems to be available. This means starting of videos from respective sources after proper login does not take place. (I am sorry for the English)

If I search by highlighting text and then right click + 'search google for...' the following link address in the next page always includes the text "client=ubuntu".

As i'm using ubuntu that might not seem strange, but it's strange to me because I use this addon which is supposed to spoof my browser and O/S and also in about config I have: privacy.resistFingerprinting and "privacy.trackingprotection.fingerprinting.enabled"' both set to "true".

Can anyone tell me how google is able to detect this info?

And seeing as the about:config settings dont seem to work... how i'm able to stop it?

Viewing two tabs side-by-side can be very helpful, for example when copying information across. This used to work in older version using the AddOns tiled=tabs/pages. But in FF76 tiled-pages has very limited functionality and does not work for me for any page that requires javascript - so most pages requiring logins are out.

How can I get this very time-saving functionality back?

And neither is the Temporary Containers Addon. I just did fresh brand new initial Firefox install on both the most updated version of Windows 10 and the most recent version of Ubuntu 20.04. All addons appear in the toolbar except these 2. I've tried installing these 2 first. I've tried installing them last, then disabling all the other addons, uninstalling them and reinstalling them. Nothing will make them appear in the toolbar, yet they appear as enabled when they display under the addons > extensions. Also, hitting the extension shortcuts will not bring up the addon interaction screen for any of the addons, e.g. Ctrl U or Ctrl <period> or whatever the relevant shortcut command is. This appears to only be an issue with FRESH Firefox install, because on my other computer running Windows 10 I've had the Multiaccount Containers Addon in the toolbar for 6 months without issue through many older versions of Firefox; and after I updated (rather than fresh install) to this latest version the Multiaccount Containers Addon remains in the toolbar without issue.

Can anyone suggest how I can get theMultiaccount Containers Addon and Temporary Containers Addon to appear in the toolbar? And why are none of the extension shortcuts working - could I be executing them on the wrong screen? I've been trying them on the Addons > Extensions screen.

When downloading pdf, html and other files I recently started getting an "Executable files may contain viruses or other malicious code" warning. This is annoying and definitely nothing I didn't know. Besides, many of these files were written by me, so this simply represents an additional annoyance in my workflow. How do I permanently disable this behavior?

On the entertainment media site Buzzfeed, clicking on a post of an embedded Twitter video gives me a blank white image. No error message like "Unable to play the file". I did a clear history, cache & cookies and refreshed Firefox. I ran the apt update for Ubunto. It had been operating smoothly in the past. If I go to Twitter, it plays. It just goes blank when I click on the video embedded in the post.

Thank you for any assistance.
