Hi, I really love everything about Firefox Developer Edition, except the JSON viewer. I'm used to looking at plain formatted JSON like the JSON Formatter plugin provide. But, even thought I have installed JSON Formatter (https://addons.mozilla.org/en-US/firefox/addon/json-formatter/?src=recommended), it only shows this tree/table-ish viewer that comes with Firefox Developer Edition. Is there any way to disable this feature and use a plugin for this, just as in Firefox ?

A week ago, when starting Firefox, the message 'updating Firefox . . . ' appeared before the progrom loaded. I've seen this before and it has always continued to load Firefox. This time, after some hard-drive activity, the program did not load. I started looking for support and chose to uninstal v72 - shut down my laptop and restarted it. I downloaded the latest version and at the end of install - where 'run firefox' is expected - nothing happened. I have since uninstalled and downloaded the latest beta version (73) - and now, when I ask to run the program, it opens a window but all the tabs are 'dead' and no matter what I type, the program does not connect to the internet (i.e. Google search or direct to a known web address). If I select settings, I can see the drop-down list - but if I select 'Add-ons' (for example) - nothing happens. I attempted to run my laptop in safe mode, but I have no recall of the password needed to get past the login screen. Is there anything simple I can do to bring my Firefox back to life?

After starting Firefox. If I navigate to a page to soon it jumps back to the start page again (about:blank for me). Like it's restaring again somewhat. Just before the page is reste there seems like a windows opening in the bottom right but it closes before I manage to see content. Only add-on I have i uBlock Origin. Do you have any idea why this is happening. Is there some log I can look at or enable to see what is really happening? 73.0b7 x64 on Windown 10

The Symptom:

1) In case of browsing https://stock.adobe.com/ only,

2) httpd returns 400 Error (cf. attached image).

3) when I use private mode, everything works perfect. I can browse, login and any other things.

4) Happens only in one Windows10 PC.


What I have checked:

1) Erased all cookies of *.adobe.com -> 400 Error

2) Browse with firefox on other PC -> IT WORKS!

3) Browse with Chrome on the same/other PC -> IT WORKS!

4) Launch firefox in safemode and disabled all add-ons -> 400 Error

5) Browse the site in Private mode-> IT WORKS!

6) Tried to read http headers by Dev. Tools (see the attached figure)-> No Idea! (unfortunately)

7) When I requested favicon.ico and roborts.txt, the both always returned 200 status code and they are fine.


Question:

According to my troubleshooting, It must be clientside problem. I did everything I can think of, but 400 httpd error persists, only in one PC, this firefox only. What is the possible cause?

Hello: FF dev build 73.0b7 w10p. (No stable on this mac - yes mac). I want to remove from the address bar, the 2 icons taking up space in the address bar, that I never use. Do I need to create a user file .css? I can if nec. The 2 icons are to the L of the addr. bar 1- "no trackers known..." & 2- "verified by amazon". The "remove" context menu item is grayed out. -What I really want is to SEE the address I'm typing into the address bar, when FF is NOT in full monitor pg mode. 23" W monitor & I often have FF in only 1/2 of the full monitor (so I can see another non-related window at same time). But only the down carot is visible in this "1/2 mode' status & I can't see anything of what I type, nor anything in the address bar already. I use the address bar search like 99% of the time & I really like this shortcut! (If it was fully useful, in 1/2 mode, even more). My guess is that removing those unused icons will allow more space in addr. bar to see what I'm typing -- right? Thank you.

I'm currently on 73.0b5 (64-bit) on Windows 10. I'm trying to use the "Update to 73.0 Beta 11" button from the "About" screen to update the browser. This normally works but today, it's having problems and I suspect it's due to our corporate policies being changed around.

I'm going to submit a request to our enterprise idiot to have this fixed in their whitelists, etc. but before I can do that, I need to know what kinds of permissions to request. What's responsible for the update process and what folders need to have which permissions for this to work?

Because right now, pressing the "Update to 73.0 Beta 11" button results in Firefox downloading the update but when it tries to install it, it fails with the "Update failed. Download the latest version" message in the "About" screen (when it was working last week without a single hitch).

According to my about:support details, I'm seeing the following:

- Update Folder: C:\ProgramData\Mozilla\updates\<Long String> - Application Binary: C:\Program Files\Firefox Developer Edition\firefox.exe - Profile Folder: C:\Users\<my username>\AppData\Roaming\Mozilla\Firefox\Profiles\<string>.dev-edition-default - Antivirus, Antispyware, and Firewall are all governed by McAfee Endpoint Security (which hasn't been an issue in the past).

I suspect that all of this is due to our enterprise guys modifying the permissions that our "elevated permissions" has... So once I have a better understanding of what things need which permissions, I'll be able to request that the elevated permissions be modified accordingly.

Any insight into this would be appreciated. It's a shame we don't have logs that clearly explain what folders or files lack whatever permissions to better understand bottlenecks like this. Maybe we do have that and I'm just not aware of it?

After a recent update I noticed my firefox account stopped working and in the preferences page I started seeing the message that "Your browser is managed by you organization".

I did some research and found that these settings (identity.fxaccounts.enabled:false in about:config) are managed through a policies.json file found in /Applications/Firefox.app/Contents/Resources/distribution in Mac. But there is no distribution folder in the above path.

The problem persists even after uninstalling and reinstalling firefox and refreshing profiles.

PS: My computer is not managed by an organization.

I installed Nightly Firefox 74.0a1 and I am still able to sideload extension. But based on this article https://blog.mozilla.org/addons/2019/10/31/firefox-to-discontinue-sideloaded-extensions/, sideloading will not be supported in Firefox 74. I tested both of sideloading methods (https://extensionworkshop.com/documentation/publish/distribute-sideloading/?utm_source=blog.mozilla.org&utm_medium=post&utm_campaign=2019-sideloaded-discontinued) and the extension was able to be sideloaded successfully in both ways. Does anyone know the reason?

For many years now I have used the beta channel. At the end of last week I checked for updates and received 73.0b11. I was already on 73.0 beta, probably b10.

Since that update I am unable to edit the contents of the address bar unless I launch a Private Window, where the problem doesn't occur.

I have tried using the "Restart with Add-ons Disabled..." option from the Help menu but the problem remains.

I am running on Windows 10, 64-bit, [Version 10.0.18363.592], with all the latest Microsoft updates.

I have been a Linux and Firefox user for many years. Whenever I wanted to migrate my profile to a new Linux installation, all I had to do was copy the contents of the old Linux installation profile folder to the new Linux installation profile folder (No matter that they had different names). Now I am trying to do it from Kubuntu 18.04 (Firefox 73.0 from PPA) to Kubuntu 20.04 (Firefox 73.0). I am doing what is explained in this guide: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

But after doing that when I start Firefox in Kubuntu 20.04, a message appears warning that my profile data may get corrupted and therefore to protect my data it gives me only two options, starting Firefox with a new empty profile or quit firefox. So I am not able to perform the migration. How can I migrate my old profile in ofline mode? I don't want anything that requires having an account or uploading my data to some cloud thing (which I think what that Sync thing is). That is, I want to do the migration in offline mode, locally, on my machine. Thank you.

I'm trying to write a script that would have firefox take a screenshot from the command line, in headless mode (I think). Only issue is that the site I'm trying to screenshot takes a couple of seconds to finish loading, so I only get a partially loaded screenshot. The only option available on the command line is --window-size...

I can take a screenshot inside the dev console with many more options, including --delay (https://developer.mozilla.org/en-US/docs/Tools/Taking_screenshots), is there any way to replicate these options on the command line?

Any other suggestions to script taking a screenshot of a site with delay added?

I log into a secure site that grabs information from other secure sites which requires setting up passwords, authentication and ETC. Some these links need to be refreshed from time to time and requires an series of actions on my part to re-establish these automated links. The issue is when I try to re-establish the link, the first page will launch and then if I hit any key the link closes immediately. I think there is a security setting issue that is preventing me from making the appropriate re-linking procedures. Please note: This process work using Firefox at time however no longer works. I tried re-establish these links using Google and it worked.

Any advice would be greatly appreciated.
