Firefox Support Forum

On many, many, websites when logging in I am getting the above message.

These sites work no issues but why is Firefox not recognized as a accepted browser.

Firefox says I am using the current release, and is up to date?

All this sites are important log on, like BofA, OptumRx, etc.

I am using an iMac, Mac OS 10.11.6.

It is still a really good machine.

Hi!, recently i have been having this browsing problem whenever I open the news website at https://www.cgtn.com/channel/documentary. The site wont load and error is shown- "cannot load M3U8:levelLoadTimeOut". Have tried numerous times but failed to load. However other web sites have no problem and prior to this I am able to surf at all times. What must I do to get back the browsing? Any help is appreciated. Thanks

Firefox has become very slow for some two weeks om my desktop with Linux Xubuntu 18.04. Some sites can be approached without problems except for the speed, other sites are opened after some time, but freeze so that scrolling and clicking on links won't work. I tried to find an answer in the Settings......

my desktop computer keeps freezing. after shuting firefox and reopening it, it comes up with 'an old version of firefox is running in the background. firefox needs to close this to continue'. How do I delete an old version please I am running windows 7, 64 bit pro

I have some websites in the internal network with self signed certificate which I have registered in the exceptions. But every time I visit them he asks me to put them back in the exceptions. Is there a way to fix this problem?

On thursday 4/28/22 I lost the ability to use Gmail via firefox. I keep getting errors such as check your network connection and Oops... the system encountered an error (#001)

I have updated my browser on my windows computer, my network speed, upload and download speed is good. All other websites are functioning just fine. Only Gmail seems to be affected on my computer. (It works fine from other computers and from my phone.)

Do you know how I can make it work again? Please help!?!

Within the last couple of days, everytime I use Firefox it asks to update itself. I have to allow it but there must be a minor glitch. I am using 101.0.1 on 64 bit Windows 10. Any suggestions would be appreciated.

Firefox auto-installed an update and now when I try to open the browser, I receive this

Error: Platform version '102.0' is not compatible with minVersion >=101.0.1 maxVersion<=101.0.1

How can I fix this???

When I type my website in the bar, firefox puts www in front of it, which causes the warning page: firefox detected a potential security threat and did not continue to www.karinchappell.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

If I remove the www by backspacing it, the page loads correctly.

I've checked the website: "SSL is enabled on your site, and an SSL certificate was detected on your site."

When I've asked around the techies I know, I've been told this is an antiquated way of dealing with it. Please advise.

Steps to re-create: create a new campagin attempt to change the display image using the hover-button over the image on the page.

What happens: I click the "change image" button, it gives me the os file picker. I select the file i want and click open and the file picker goes away. The "progress" bar at the top of the image shows up, changes through several states it seems. Then all screens freeze, and the computer stops responding to all output.

Supplemental info: This started happening after an update from ubuntu 18.04 lts to 21 to 22.04 lts. So I know I was not using a flatpak before and I am now.

I've attempted to use strace to figure out what's happening at the time of the freeze I'll include a picture of that if this form does not cause my entire pc to freeze. But didn't really get any useful info from that. I tried reading dmesg at the time of the crash but so far the screen freezes before any relevent information pops up. I've not been able to find any logs about whats going in previous dmesg logs.

Troubleshooting steps: I've attempted the same procedure in firefox's safe mode. This does not seem to stop the crash. I've attempted the same procedure using chrome and this works as it should.

A friend used my PC and now whenever I have to fill in a form with my details their name always shows up above mine as a possible autofill option. How do I stop this?

I turned on my computer like any other normal day this morning, except when I launched firefox it was like it was freshly installed, all my passwords, usernames, cookies, saved bookmarks, work related history material is all GONE it's like I just installed firefox for the first time. A lot of these passwords I dont know off the top of my head so I'm going to have to ask my business partners for ALL the passwords... Why did firefox do this? What is the problem??

Every time I run browser it messages me that downloaded file contains a virus or malware, even I deleted the file long time ago. I tried Ctrl+J "Remove from history", "Clear downloads" and Organize/Delete that entry - Nothing helps. Its deleting, but when I run Firefox its appears again and again. This bug is terrible annoying, please fix it.

When using Mozilla/Firefox (but not when using Chrome) many links do not work (e.g tracking packages from UPS or FedEx). Also even though under setting I check"save logins and passwords for websites) they are not being saved. I need to login manually to access most websites

Please advise how to correct these issues. Due to security issues I greatly prefer to avoid Chrome/Google !

I'm not sure what is causing this, but it started at least a few months ago. I will be using firefox, and anywhere between a few minutes, or a few days, it will suddenly stop loading anything and I will have to completely quit it and restart it to get anything working again. No, it is not the HTTP3 problem; that was the first thing I tried. I've also uninstalled, and reinstalled the entire program, clearing all settings, etc. I am on windows. Generally good on firefox updates, will check and update usually every week or two.

Funny thing is, I also installed firefox nightly and that does not have this problem (although I have not used it as extensively as I normally do when browsing, so maybe I didn't hit whatever triggers this issue). It also works properly on other computers (as far as I'm aware). So I still think something is corrupt or wrong with my normal firefox program. I just don't know what or how.

I am using current version of FF on an HP W10 laptop. I use Lastpass as my password manager. Periodically, I need to log into optumrx.com, and I can't remember the last time I had a problem. The past few days, when I use Lastpass or just open optumrx on my own, I am asked to verify a code texted to me cell phone. It recognizes me by name and then proceeds to cycle endlessly through several pages without landing and stopping on that page. I contacted optumrx and they suggested using Edge, which did behave normally.

My husband, Wayne, a casual computer user, has been having trouble getting into Firefox for some time. He's been getting along on MS Edge since then. He wants to get back to Firefox for his bookmarks that are there. His problem is that Firefox doesn't start. When he tries to start it, a gray window appears briefly with a rotating blue circle and then disappears in less than a minute. While it's up, Firefox shows up in Task Manager with "not responding" or "suspended" or nothing. I note that the last Firefox update was 6/14/2022 according to the date modified on the file in Crash Reports, InstallTime2022060832. This is about the time he began having problems.

During the brief time it's up, there is no menu button (3 short lines), so Refreshing or Troubleshooting are not options. I believe my only option is to Uninstall (without removing user data) and then reinstall Firefox, ie a "Clean Install". I see an option to Refresh during the Uninstall dialog. Might that work?

Hi, After the last update Firefox asks me what I want to do with the pdf files and to choose between Open in browser, Open with and Save file but even if I choose Open in Firefox it always downloads the file in the download folder of the PC and then opens it, This is really annoying because then I have to delete them manually. What can I do? Thank you

Sometimes, if the computer is offline and Firefox is open, when the computer goes back online Firefox can't connect to any website, with the page "Hmm. We’re having trouble finding that site.". The only fix is to close Firefox and open it again. Going offline doesn't always do this, and while I'm not sure of what exactly causes this to happen, a way to easily reproduce it is:

• Turn off the Wi-Fi;
• Reboot the computer;
• Open Firefox;
• Turn on the Wi-Fi;

After the computer is connected, refreshing the page sends you to "Hmm. We’re having trouble finding that site.". You have to restart Firefox.

A way that doesn't 100% reproduce it, but works enough times, is to reboot the computer without turning off the Wi-Fi, and open Firefox as soon as possible (before the computer manages to connect to the router, which is the part that isn't always consistent). Rarely, it happens after suspending the computer, or after a disconnection due to an unstable connection. I can reproduce it in Firefox's safe mode. I have a hunch that maybe this is related to networking drivers.

I'm using a Lenovo IdeaPad 5 14ARE05 (Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)), Linux NixOS 22.11 (I don't know about Windows).

Ask me for any log you might need.

This is kinda a duplicate of https://support.mozilla.org/en-US/questions/1078253, except that their solution does nothing to me.
