I have been having problems with firefox lately. Every time I try to run the program it automatically closes without giving an error message. I am running Windows 10 and this happens in safe mode as well. I have tried doing a clean install of firefox - that did not fix the problem. I tried deleting my profile after uninstalling then doing a fresh install, this did not fix the problem either. I ran a virus scan and did not detect any malware. I don't know what else to try.

tell me who knows, how to stop all tabs? Even when I enable the "offline mode", tabs with heavy javascript continue trying to load, consuming CPU resources. I want they to stop immideately. I tried different extensions, but results are unsatisfactory. Does anybody know some trick? My goal is to find a method to flush all javascript structures in RAM. I explored about:memory, and tried the vmmap.exe (process memory analyzer) from the Sysinternals Suite, but I have not succeeded so far. Auto unload tab -- is not a solution. For example I clicked on links and opened 30 tabs in background. PC starts working very slow, Now I want to stop all them, and to read the loaded information (webpages). How to do it? I think it is the weakest side of Firefox. Needed to abrupt all attempts to make network connection, after the "offline mode" is enabled. I need something to stop javascript's attempts to connect, to calm it down. I want to start read webpages already loaded, and javascript occupies CPU. To kill threads in the Process Manager is not a way to do at all, Auto-unload also, I want to read those webpages. I have enough of RAM, it is not used more then a half. Many years ago, when there was HTML4, I used for a little the Maxton browser. It had a button to stop all pages. All similiar Firefox extensions do not act effectively like that. the issue not in scarcity of RAM, but in a badly design of browser's architecture, that javascript occupies users' PCs.

I recently went to Twitter with Firefox v. 72.0.2 on my Windows 10 desktop, and Twitter loaded the mobile version of the page and told me it was because I was using an older version of Internet Explorer. So, I cleared all of my history and cache and tried it again, and it was okay. Then a couple of hours later, I went to Twitter again and again I got the mobile version of the webpage and I got the previous error message. All I had to do to correct it that time was load the page again. And, yes, it accuses me of having an older version of "Internet Explorer."

What gives?

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?

I'm getting "Error code: SEC_ERROR_CA_CERT_INVALID" on every page. (Full details in screenshot)

I've tried accessing google and reddit, which I had been browsing no problem, but no luck. I can't even access Mozilla help. And I haven't been able to bypass anything.

I've been googling this (on Chrome! yuck!), with no luck. If I stumbled upon the answer, I wasn't tech savvy enough to recognize or implement it.

Could someone give me a hand?

I get this rubbish: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.facebook.com because this web site requires a secure connection.

What can you do about it?

www.facebook.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the web site, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

If my firefox start page name is e.g. "http:/world.com/WeAreTheWorld.htm" it doesn't work, because firefox is starting with "http:/world.com/wearetheworld.htm". All upper case letters are moved to lower case letters. The bookmark routine of firefox doesn't have this issue. I think that is a bug of firefox whish should be fixed.

Most of the time but not all of the time Firefox appears to be missing all menus, but it seems that it has actually just nulled all the strings. The image shows the problem. This seems to be the case 100% if I click a link from email. Starting a new window does show the menu. I've tried the reset menu procedures I have found with no effect.

This is MacOS Catalina. I don't recall this happening prior to upgrading to Catalina.

Hi all, Long time user of Firefox and love it, however on my work computer it is very unstable. When loading up it seems fine until I click into another window and on returning FIrefox is is full screen mode.

I then have to Alt\view\fullscreen and then top right, restore to see the taskbar once again, however on top of this it seems very unstable and often when trying to click back into Firfox it will not allow me to do so and appears as if it has crashed. I then have to Alt-contr-del to close the program and stat again.

Have tried resetting Firefox without joy so a bit stuck as to what the issue could be? Any assistant would be greatly appreciate as I run all the same plug-ins on my home computer and works perfectly!

Dear All, my Firefox is broken. It starts and shows a blank tab, but I cannot open any site, not even about:config or the options pane. Typing anything in the address bar or the search bar and pressing Return does nothing.

The only things I can do is opening new tabs (which will remain blank), and clicking on menu items in the main menu. None of the items that would open any dialog works, though.

So far I have tried:

  • Starting Firefox in safe mode
  • Creating and using a new profile (firefox.exe /p)
  • Uninstall FF and re-installing the latest version
  • Uninstalling FF and installing a previous version (downgrade), using a new profile
  • Deleting all mozilla and firefox entries in the registry in an uninstall / reinstall cycle

Now I am out of ideas. Any help is welcome. Thanks!

After a recent beta version installed, my profile seems to have a corrupt configuration file. But I don't know how to figure out which one. It only happens on my Windows 10 laptop. My profile syncs with another Windows 10 laptop, 2 user accounts on a Linux Mint desktop, and an LG phone. I followed the support article and changed the settings so that I was only on the release channel, rather than the Beta channel. I tried the Refresh Firefox. After resyncing my profile, the error returned. I uninstalled the newer Beta release, completely deleted the User/AppData/Roaming/Mozilla folder. I reinstalled the current release (72.0.2). After resyncing my profile, the error still returned. Every time I start Firefox, I get the annoyance of the error dialog box. After clicking OK, Firefox opens and works perfectly fine. How do I find which file in my profile is causing the error on just one computer?
