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.

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?

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.

I'm trying to debug a web page written in html5 with a serverside php that emails user input to me. The changes are minor aesthetic tweaks that only take a minute to change and then test.

It took me a while to realize that Firefox is not completely clearing the cache unless I exit FF and restart. That's a lot of effort to test one change in an html file, so I would really like to completely clear the cache. Does anyone know what is being left behind and where?

I've been having issues for quite a while on this machine where my Firefox (tabs and sometimes all windows) keep crashing. The issue seemed to disappear at the beginning of this week (from 2020-04-18, 3:22 p.m. to 2020-04-22, 10:15 a.m. no crashes). However yesterday (April 22 2020) it came back full force.

I have tried to:

  • Re-install Firefox
  • Remove profile and re-install Firefox
  • Run it in safe-mode

None of these options seems to help (other than since running Firefox today in safe mode it crashed only once).

I have another machine (XPS 13) also running Arch and the same user profile, and that does not seem to have any issues.

Crash IDs - Both on April 23 2020 Normal mode - 4dd8d844-e5fa-42df-b57d-88ceb0200423 Safe mode - 49d18196-8146-4268-8e76-e546c0200423

It looks like 'Raindrop.io' and 'uBlock Origin' were updated yesterday.

So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

I am a software developer for a Human Resource Information System (HRIS) called EnterpriseAxis. My HRIS software checks the IP address of each user to determine whether or not the user is on the company's LAN or VPN. However, there is a bug in Firefox that prevents this security feature from working.

The bug is in DNS-to-HTTPS. When this feature is enabled in Firefox, it changes the value of the REMOTE_ADDR server variable. Normally, when a VPN tunnel is active, REMOTE_ADDR contains the workstation's IP address, such as 192.168.11.6. However, when DNS-to-HTTPS is enabled, REMOTE_ADDR contains the router's WAN IP address, such as 96.91.16.207.

Please correct the issue.

For work I use a site at egov.ice.gov

Today, I received this notification:

BEGIN====

On Monday, Aug. 3, 2020, the Student and Exchange Visitor Program (SEVP) will make changes to the way a user connects to The Student and Exchange Visitor Information System (SEVIS) via browsers and batch software/middleware. The most notable of these impacts will be the complete lack of support for the Firefox browser. On Monday, Aug. 3, 2020, all versions of Firefox going back to at least v31.3.0 will cease to connect to the SEVIS websites. SEVP recommends the use of either Chrome or Internet Explorer (IE) browsers.

END==========

I send notices to the SEVP helpdesk asking for more information, but I really do not understand the rationale behind this decision. Is there a group at Mozilla that is interested in this kind of issue?

Hello.

I use Firefox 68.8esr on a Linux Mint Debian Edition 3 laptop.

Suddenly (today), I have no more audio anywhere : no sound when streaming videos (YouTube, Vimeo, ...) no sound from radio web sites, although I can see that the streaming is working. All other software play audio normally (VLC, Audacious, my other browser - Chromium). I have reinstalled the packages of Firefox and for the Flash plugin (although, obviously most of the web sites don't rely on Flash) and I have tried running Firefox in safe mode, it does not change a thing. I have checked the online docs ( https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_html5-audio-and-video ) and made sure it's not an autoplay block.

Any suggestions ?

A lot of pages that uses materialized design CSS framework seems to have issues rendering correctly in Firefox. I see all strange CSS properties or HTML elements instead of the correctly rendered version. Not sure if it is only an issue with materialized design or a deeper issue, but I have seen this happening on multiple sites. For example this link:

You can see the different results between Chrome and Firefox in the attached images.

Actually, my question is totally opposite to https://support.mozilla.org/en-US/questions/1281825 where the user wants to use Alt+D to navigate the menu bar – in my case menu bar is completely redundant and I would be 100% happy if it was removed. Now when I try to focus on the location bar and quickly type some query I open the menu instead (despite the fact that `ui.key.menuAccessKeyFocuses` is set to `false`) and execute some random action like closing whole browser or a random tab. My habit for pressing Alt+D is so strong that I cannot just move to Ctrl+L without constantly destroying my workflow.

I would like to completely disable the navigation via Alt+_ keys on menu bar. I would like it just not to exist. I am using German locales if that matters. How can I achieve it?
