Firefox Support Forum

Hi,

Firefox issues warning while accessing websites which are signed by Internal CAs. However, we could see the same website working fine with Microsoft Edge, Google Chrome, etc.

Firefox work fine while accessing websites which are signed by Public CAs. The issue is only with websites signed with internal / Private CAs.

Below is the error message:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to "XXXX.XXXXX.com". If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

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

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

Need some help with Firefox crashing. System: Windows 8.1 64 Bit instilled on a Samsung SSD, 24 GB free space, 24 Gigs RAM, Firefox installed on conventional HDD (G:\) drive, 1.03 TB free space. This has been the standing configuration for many years, working with no problems.

Problems began with FF update 111.0. Any attempt to download files (.jpg or .pdf) would cause the “save” button to freeze, and after a seconds FF would crash. If an attempt was made to change a setting FF would again crash so quickly it was impossible to attempt any changes. Oddly enough, FF update 111.0.1 fixed the issue (or so I thought) and things returned to normal. I assumed whatever caused the problem had been fixed.

Unfortunately, every update beyond 111.0.1 reverts back to the same freezing and crashing behavior. I have attempted the following with all updates above 111.0.1 in an effort to correct the issue. So far nothing has worked. BTW, Brave and Chrome work just fine.

Cleared out all cache and cookies. Changed download folder Opening in safe (trouble shooting) mode Clean install(s) Disabled hardware acceleration. Putting the entire program on C:\ drive (apparently the newer FF installer does not allow custom installations any more). Checked and updated all drivers

Currently I have disabled automatic updates as none of them have the same freeze/crash issue. I am out of ideas and would certainly be glad to get any advice. At this point Brave is going to be my new default browser. Yes, I know 8.1 is no longer supported but I am not in a position to replace this PC at the moment.

I bought a new laptop. I installed ZoneAlarm and Virus Protection for Windows 11 as I thought Maybe Wolf and Windows Defender might be the problem. I did everything suggested by Mozilla to get it to let me log on. To no avail.

I did everything. I still cannot get access to https://www.chewy.com - despite my logging in many many times. Please tell me how to fix this. This is STUPID!

This is the error message I keep getting: Access Denied You don't have permission to access "http://www.chewy.com/app/login" on this server.

My e-mail address changed, but the old one keeps popping up. I need to ELIMINATE the old one and use ONLY the new one. I've told various organizations, businesses, etc., to make the change. I want Mozilla Firefox to ELIMINATE the old one and use ONLY the new one. Help!

Logged into Twitch, can see and type in chat, but video and audio do not work. This happens on my Main Twitch account as well as my alternate. I do not have this issue with Google or Edge.

This is the last time I'm going to inquire about this topic. I will switch browsers bc Firefox touts their superior product with hundreds of complaints I just cant ignore further.

I USED to be able to close Firefox browser with confidence. Now I can expect to waste several minutes a hour/day logging back into my websites bc Firefox no longer remembers my login information..

I want ONE thing from Firefox, step by step by step instructions on how to put your browser back to the way it was before you'all decided to to "make things better".

my deepest regrets!!

How do I remove the policy that controls this: "Your browser is being managed by your organization."

I do not have a "Mozlla" in the policies location. All information I see for removing the statement below shows that the word Mozlla is what you remove with Regedit. The information "Your Browser is being managed by your organization."

All I have under Policies is: Adobe, Dell, Google, HP, Microsoft

Hello, I've been trying to use my Firefox browser for the past week and nothing I do seems to work. Whenever I click the icon on my Windows desktop, it sends me the following Mozilla Crash Report:

We're Sorry

Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.

To help us diagnose and fix the problem, you can send us a crash report.

I've restarted my computer and tried to change multiple settings, but the same pop up message keeps appearing. I've checked the box that sends the crash to Mozilla and clicked the button that says Restart Firefox, but still nothing. There's also a "Detail" button that provides a bunch of information that I'm not sure how to interpret haha but I can try to copy that if you think it would be helpful.

I would appreciate any help. I'm looking to get a new computer (not sure if that is part of the issue), but I'm really hoping to be able to save the bookmarks I had.

Thank you.

Subject line says it all. I can no longer highlight something, say, in Facebook or from a website, "copy" it and "paste" it into a message. Is it better to try restoring Firefox to an earlier version, or to abandon Firefox and use a totally different browser ? It all worked fine prior to the update today.

Thanks for the help !

Why can I no longer use the Firefox default theme? I can select it, and it is listed as "Enabled" but the plain grey screen keeps showing not the default. Also, is there away to go back to Firefox 88.0.1 and not have it update again? I went to Add-ons & Themes and disable automatic updates but I still got the prompt informing me to restart Firefox to update. Is it just me or is Firefox really getting worse with each update?

I find the updated version difficult to see. I've used Firefox happily for at least 15 years with no problems and appreciate its existence.

But the icons I see look just like the Bing icons - very finely drawn and small - and I can't control the colors. Also, the PBS pages have white rectangles scattered around, possibly unfinished labels

So how can I safely reinstall Firefox 8.8?

Thanks - P.B.

Firefox 89.0 for MAC is a disaster. Tab toolbar is above the URL bar -- Horrendous. Worse yet, is that tabs and links are loading SO SLOWLY!!! I have deleted history and cache. Have rebooted and reloaded. Still a mess. Can I go back to previous Firefox? How do I do that? Is there a way to fix the slow load. I am just hating this new situation. A total mess.

After v. 89 was released firefox started having this issue, basically when i start firefox it crashes. I have tried several different solutions like fresh installs and refreshes. The one that has worked best so far is deleting the profile file and restarting my computer. It will usually let me use it until i close out of it entirely. My computer is currently running windows 7 if rhat is important.

Every time I download a file, when the box comes up asking me what I want to do it is set to "Open with" instead of "Save As", so I have to take the extra step of turning it back to "Save As." I don't want to set it to ALWAYS Save As, because sometimes I DO open things in Firefox or other programs, but I want it to be set to Save As by default among those three options, because 90% of the time that is what I am doing and having to add an extra step is slowing me down and putting me off my stride when downloading a number of things at once. There does not seem to be any option to resolve this.

Included is an example. Save As used to be the go-to option. Now it is not, and I can't seem to change this.
