Hello! I can't login to my x.com account from Firefox 115.35.2esr on Windows 7 SP1. I'd was stay logged in many years before I accidentally clear my cookies. And now I can't login. It just reloaded input form when I type my login and press "Next"button. I tryed login from Private mode, I tryed to disable all addons. Nothing helped. But I still can login/logout from Firefox 140.10.2 on Windows 11.

In Firefox console I see

errors [ {…} ] 0 Object { code: 399, message: "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1" } code 399 message "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1"

and

Can anyone help me to fix it?

Hello, I have Windows 7 and I use Firefox ESR as my browser. It has work correctly for years now, but since a couple of days it has problems with downloading the latest updates. It asks me download the update but as I go into the settings page, the download is stuck at 0 kB. I also get a message box that FF is not able to download the update and it sends me to a Mozilla Firefox ESR download page and when I want to download the ESR version, FF cannot open the page with the installation file. Also many other links on the Mozilla page do not open or do not open correctly. Also it doesn't open this support page, I am writing this messages through my phone. Also it doesn't open the website bol.com. So what can I do. I have already tried clearing the cache and cookies. It doesn't help. I hope you can help.

Je ne peux plus accéder à Facebook sur l'ordinateur. Attente éternelle de la prise en compte des mes codes. Alors que j'y accède normalement sur mon téléphone portable et sur ma tablette. Je suis protégé par Bitdefender. Quid ? Merci :-)

I tried to remove the new 'profile'. I don't want it. now ALL my data, settings & bookmarks are GONE ! Help me revert to & restore the previous account settings !!!!!

I'm reposting a question already opened here because a moderator suggested to do so. Actually I though I was posting to the international forum from the URL...

I was trying to access a local HTTPS website of an embedded device (a Siemens S7-1500 PLC) that is using a self-signed certificate, but was unable to go on (attached image #1, in Italian language) due to the the SEC_ERROR_REUSED_ISSUER_AND_SERIAL error. I've browsed a similar PLC webserver in the past, so the fact that the device exposes a similar certificate serial number is not so strange for me, considering also it's self-signed.

The problem is that I cannot follow the instructions of the Mozilla knowledgebase here because I'm not able to identify the correct certificate of the website!

In the attached image #2 you can see that the connection is detected as not encrypted, I suppose because only the form part of the HTML that is posting the data using HTTPS while the rest is using HTTP, but I'm not sure. If I click on the padlock icon (attached image #3) the info about the current certificate is not displayed.

Then I went into Tools > Options and searched for "certificates"; as you can see in the attached images #4 and #5, neither in the Servers tab nor in the Authorities tab I can find any item that is related to 192.168.10.2 (the webserver IP address) or Siemens (the embedded device manufacturer). But unfortunately the error persist! Initially there was a 192.168.10.2:443 line in the Servers tab and I removed it and restarted Firefox, but it didn't solve, so at the moment the situation is the one depicted by the attachments.

I had to use Microsoft Edge to access the website, but I would like to solve this issue and use Firefox instead. Is there anything else I can do to bypass the error? Why doesn't the error page provide a way to correctly identify the wrong certificate using its fingerprint and/or name? Or, maybe, is there a way to disable this check for local IP addresses or for items in a whitelist?

Thanks for your help.

I am getting the message "updates are disabled by the admin." I am the only one here so I don't know how that happened. I need to install Slack but need to update first. I followed the steps to edit registry but still can't update. Please advise.

Halfway through today I'm unableto access three sites which I use regularly.using a VPN: 1337X.TO EZTVX.TO THEPIRATEBAY.ORG

Getting the error message:

An error occurred during a connection to thepiratebay.org. PR_END_OF_FILE_ERROR Error code: PR_END_OF_FILE_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem.

I am able to access THEPIRATEBAY.ORG with Opera <ptooh> so the site itself obviously doesn't have a problem.

I've tried changng my VPN location from the UK to Amsterdam, NL and to Washington, USA but none of those locations have helped.

My wife needsher daily fix of American soaps and Police dramas which never get to us here in the UK

How can I get around this, I really don't want to go down the TOR route unless I absolutely have to.

Recently passkey function stopped working for Roboform which requires entering password for each login event. Roboform support indicates the issue is being caused be Firefox function. Please advise on this issue. Thanks,

I use Firefox frequently as it is the most useful browser I have. I want to keep a clean desktop and do not have icons on my desktop. Every time Firefox updates, it places an icon on my desktop. I do not want it there and delete it. It is very, very annoying to have to delete every time there is an update. How can I keep that from putting it on my desktop? If the thinking is that if it gets put there, I will use it, that will be what keeps me from using it. If I cannot find a way to stop it, I will remove the program altogether and figure out a way to do the things I currently do with Firefox. Please let me know how to accomplish keeping my desktop clean.

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

Hi there,

I'm wondering if I am experiencing intended behavior or if I've stumbled upon a bug. I am sometimes downloading files in a staggered manner (i.e., waiting for files to finish downloading before I start the next file downloads). However, any file after the first in that session shows an inaccurate progress indicator in the toolbar which includes progress of the already completed downloads.

For example, if I download two files completely, then start the download of two new files and both sit at 0%, the progress bar for the downloads actually shows 50% completed (2 files at 100%, 2 files at 0% -> Average of 4 files at 50%). I can't imagine this is intended behavior, for I imagine users would like to know how their current downloads are progressing only. This behavior is only fixed when I clear previous downloads, which resets the list to only active downloads, or when I restart the browser and start a new session.

Is there a setting where I can make the indicator report only active downloads?

Any insight is welcomed, thank you.

Hello, I've been watching MSNOW at 4pm eastern and after about half an hour it crashes. I get a message to send a report and restore the tab. I restore the tab which works for maybe ten minutes and crashes again. I am using Windows 11 on a new computer. I'd appreciate some assistance. Thanks. Bruce Caress

Moderator note: This question has been edited to precise Firefox and OS version, based on the crash reports.

Recently (about a month) I have found I often have to login to my Firefox account in order to access saved passwords etc. Sometimes from one day to the next. It never used to do this. Can't find any setting like "trust this device" or similar to stay logged in.

My Firefox 150.0.3 (64-bit) in Windows 11 on a Dell 9310 locks up when the XPS is put sleep and awakened after 5-minutes or so. No recent Extensions or Add-ons have been installed. I have yet to delete and reinstall Firefox, maybe that's the next stop. I just can't find the problem with my limited tools and experience. Thanks, and appreciate the help.
