My Firefox Developer Edition just required manual help to upgrade to 73.0b2 because the auto-upgrade failed. Not sure if that is important. All new tabs and windows had the "You have to connect to the internet" captive-portal bar across the top, but I'm on a home network without captive portal. Clicking the "go to login page" button went to a "can't find that page" error page.

I tried curl from the command-line of my Mac (10.15.2) and got this:

% curl -v http://detectportal.firefox.com/success.txt

  • Trying 2600:1415:1c00::17c0:6c92...
  • TCP_NODELAY set
  • Connected to detectportal.firefox.com (2600:1415:1c00::17c0:6c92) port 80 (#0)

302 Found


nginx

I'm prepared to believe that this is ISP-related, rather than Firefox, but on the off-chance that it's somehow down to a misconfiguration of the captive-portal detection servers right now, I thought that I'd report it here.

I've stopped this from happening by setting about:config network.captive-portal-service.enabled to false, but would ideally prefer that this not recur on the next profile reset.

So I was looking at a Facebook group this morning and saw something that was posted in the group's feed that decided to autoplay on it's own despite "Block Audio and Video" being the default within the "Settings - Autoplay" screen.

I don't understand why this is constantly an issue with Firefox. Every single time, every update, every install, it always and continually becomes an issue with websites that I visit with Firefox. Even a completely fresh install with that above-mentioned setting, it's still an issue--nothing to do with customization of any kind, it's just that Firefox isn't doing what it's supposed to do.

What's going on here with this? Why isn't Firefox able to stop autoplay of videos within Facebook? I shouldn't have to rely on website settings to turn something like that off when it's the browser that allows the playback. I'm clearly missing something (I guess) so I'd appreciate if someone can shine some light on this because it's infuriating.

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?

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.

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 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.

When I started Firefox on my laptop (Windows 10 1909) this morning, Firefox noted that it was not the default browser. I clicked Set as Default, was taken to Settings and there was no default browser listed. When I clicked the button to set the default, Firefox was not listed (only Chrome, IE and Edge were there). I installed 73.0 last week but have been using my desktop most of the time since so I'm not sure when this changed. Firefox does appear in the installed apps list and is working normally when I open it. Did Microsoft do something that prevents Firefox from being the default browser? Is there another mechanism I can use to make Firefox the default?

Thanks for any help anyone can give me.

This is a direct question as to whether Firefox saves any user NON DELETEABLE information. It appears Chrome does. These are not cookies or history as I know it. Presumably after Chrome has uploaded to a server somewhere it is then deleted or perhaps there is a timed or storage limit delete. The Chrome explanation is that "it makes the user experience faster and better". More likely is that google is increasingly being denied cookie & tracking data because of privacy addons or public opinion, they have a new way to get most of the same information. They just call it a "profile" rather than a cookie.

Old Firefox reappeared with bookmarks, but New Firefox also appeared without bookmarks. I am completely mystified as to what I should do. Delete new Firefox and continue to use old Firefox? Or is there some way to install new Firefox and keep my old bookmarks on which I rely?

I was using firefox sync account wadahi@top-mails.net just fine. that email was deleted for non-use. No verification procedure was laid out anywhere in the agreement. Then firefox modified the agreement and now sends verification codes to that email, which I no longer have access to. I am able to login in my account using the login and password , however firefox now wont allow me to change the email to the new one to receive verification code. I need access to my bookmarks and saved passwords NOW! Firefox had no rights to unilaterally change the agreement without notice to the customer. Firefox had no right to impose the verification email without letting the customer make sure his email can still recieve verification codes. Firefox failed to provide customer support because it doesnt even have a technical support email or phone number like a registered business should have. I lost access to my bookmarks and saved passwords because of negligence and reckleness of Firefox in failing to notify the customer to change the email to make sure the email can receive incoming emails and is current. I have the access to my firefox sync account, however it wont let me login without the verification code which is being sent to a nonactive email, used many years ago.

Suggested resolution: if you are a smart and relatively educated techncial support, you would realize that the same ip address would indicate that I am who I am and I should be allowed to change the email. However, firefox provided no technciall support and DID NOT EVEN HAVE A CONTACT EMAIL, while making significant profits from the customers and yet fails to provide technical support.

H A Forum I use extensively suddenly started showing content layed out in a sort of linear fashion where everything was set onto a new line. I have used this forum for more than 18 years and this is the first time this has happened, The site is a respected one, and a search for 'MSDN Forum' would provide a link(s) to my problem site. After a LOT of work trying to find what has happened has resulted in my finding that scripts and CSS seem to be skipped from being loaded by Firefox reporting the error message I mention in the title. These errors are MANY thoughout the incoming data. I subsequently tried to pursue Mozilla articles on Mixed Content Blocking, which seems to say Ishould have an option to 'disable' Firefox security with respect to the above via clicking on the 'sheild' icon and follow through to where there is supposed to be am option to 'stop/disble' - but there is no such option here so I can't check if that option is a cause of my issue. This issue is very severe as it disable ALL of the needed buttons - such as Reply, Quote and Post New Question - for a Forum, that is indeed severe! Now, I don't know if this whole issue is a fault with either Microsoft (who seem to be serving faulty data, or, Firefox for being overly coseting) I attach an image showing a portion of the errors (they extend throughout the entire list). Patricularly, the line at the top saying the Style Sheet could not be loaded summarizes the whole issue. Is there any other way I can get to disable Firefox being overly protective - I do know how to use the About:Config etc., but lack the ability to find anything relevant to this issue in any of the content there.

A further snippet of information: amongst other things, I reinstalled Window 10 and used Edge immediately after install had completed - same issues (suggesting that either both browsers are overly protective, or that the issues stem from Microsoft). I have tried most/all of the things likely to be suggested here suxh as using Safe Mode, no Extensions etc.

To save readers from becoming bored with this long essay, I'll stop here - if further info needed, just ask.

Hi all! I need help getting my Firefox running again. Today it crashed (due to lack of available RAM), I had to shut it down in the task manager. When I restarted the browser, it couldn't load any content anymore. That means the upper control bars of the browser window work as usual, the lower part of the window stays completely blank.

I can't load any websites, local servers or routers, no local content such as images, or offline htmls, nor internal pages such as about:config.

What I tried so far:

- disabeling hardware acceleration

- disabeling proxy settings

- starting firefox in safe mode

- refreshing firefox

- reinstalling firefox (73.0)

- reinstall with profile reset

- reinstall with manual deleting Program Files\Mozilla Firefox and AppData\Roaming\Mozilla\Firefox

...maybe even more.

Nothing helped.

Interestingly, even firefox portable shows the same behavior now, though at least one page was able to load after 15 minutes or so. I also noticed that the firefox.exe is still active in the taskmanager after I close the browser (under user tab, not under processes) - I have no idea if this has to do with the problem.

I would really appreciate any help! Thanks! Jay.
