Firefox Support Forum

"Your browser is managed by your organization" suddenly appeared OS:Win11 Certificates: "ImportEnterpriseRoots" I've tried: Reinstalling Firefox Installing Firefox Developer Edition (it disapeared for few days but it was back) Deleting the registry key for it (after restart it appeared again)

 I have Avast and Malwarebytes but this has never happened to me before with this anti - virus

Sometimes when I open a new tab and start typing an address, the tab disappears as if it never existed. Don't know how to replicate it, as it is random and happens just often enough to disturb me. Also not sure at which point the tab dissappears, while I am typing or when I hit enter.

This happens now a lot, sometimes I can uninstall Firefox reinstall and it works. That worked this time but only for a few days. I am back once again to where I get this error on every place I visit. I have cleared my cache etc.. uninstalled reinstalled did a restore. It is only Firefox all other browsers work fine. No idea what to do anymore and am sad because I prefer Firefox. I only have standard windows 11 home security stuff installed so nothing special or fancy firewalls. Tried turning on default fire wall. Tried all the instructions on the more info page the error screen leads to.

This error occurs on most all websites or places I need to log into

Secure Connection Failed

An error occurred during a connection to mail.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Anyone know why this is happening and a solution?

How do I add and keep the Gramerly extension in Firefox browser? I have added it many times but it often just disappears for some reason. I'm sure this happens just to piss me off, but perhaps there is a way I can get it going again. Please advise. Thank you!

After resetting my PC, I reinstalled Mozilla Firefox, but encountered an issue with it. Despite being unsure of the cause, if this problem occurs for a third time, I'm considering discontinuing the use of Firefox and advising others against it. I've lost my bookmarks multiple times, which is concerning. Although I initially attempted to recover my account using my email, I couldn't recall my password. Consequently, I utilized Mozilla's account recovery key. However, even after this process, my bookmarks, which were saved in the toolbar Come back but shortcut labeled "ROW" Bookmarks are not come back. I'm seeking assistance to retrieve them or clarity regarding Mozilla's responsibility in this matter. While apologies are not necessary, I am focused on restoring my bookmarks or exploring options for compensation for the loss incurred.

When saving/opening file dialog is on screen the whole program freezes and take forever to unfreeze to the point I have to force quite the program. The problem seems to be only in Firefox.

Safe mode - same problem, Have done a complete refresh - same problem. Clean uninstall and reinstall - same problem.

Have moved to Chrome - similar problems.

I recently noticed that fields on all Web sites I visit have an extra horizontal line at the top of the prompt. Please see attached image. This only happens on Firefox. Other browsers don't have that behavior. How can I restore the normal prompt of a straight vertical line?

Thank you!

In a sub folder, no messages show, but, above where they should be (above the column titles), it tells me there are 2 messages. How do I get to see them and stop this ever happening again?

Hello,

NOTICE: Currently using Firefox 120.0.1 "Update disabled by your system administrator" I am unable to update the browser, the computers are from the public library.

Like I state in the Subject, I configure the browser to strict privacy level, and I am able to visit any site I want. No problem. But on all of these, when I click the lock icon on the address bar I read "Connection verified by a certificate issuer that is not recognized by Mozilla." In fact, right now, I am visiting this website and I got that notice. View image "Firefox broser does not recognize the certificate issuer fortinet but I can visit the firefox suport website - Screenshot 2024-01-28 172732.png"

WOW... View the image "certificate issuer not recognized by Firefox - fortinet - when visiting support.firefox.com - Screenshot 2024-01-28 173041.png" for some of the info I get if I view more information about the certificate.

Then, after I logged out, the "Clear cookies and site data" link that appears after clicking the lock icon I mentioned before do not appear.

View the image "UNable to clear cookies and site data - proton.me - Screenshot 2024-01-28 141951 - edited.png"

In this same computer, I got the control "Clear cookies and site data." View image "able to clear cookies and site data - virustotal.com - Screenshot 2024-01-28 141825.png"

So more than one question:

I read other posts where users are unable to visit a website which has a certificate issued by an issuer that is not recognized by Mozilla. Why am I able to visit these websites?

What can I expect of the non appearing "Clear cookies and site data" link I described before?

Are these computers like totally hacked?

Hello,

I am experiencing a persistent issue with web browsers on my Lenovo Legion T5 26IAB running Windows 11 Home. Regardless of whether I use Mozilla Firefox, the browser frequently crashes. This happens at least once a day, and it seems to be unrelated to the number of tabs open or the specific content being viewed. I did the help -> diagnose mode without plugin and it crashed too, im not sure what this is realted to.

The crashes often present with an error message suggesting a failure in the new tabs or trying to load a old one, despite the fact that my system's RAM usage is typically around 60-70%. I have already updated the BIOS, Lenovo drivers, and NVIDIA graphics drivers, but the issue persists.

I'm seeking advice on what might be causing these browser crashes. Is it possible that there's a compatibility issue with Windows 11 Home? Could it be related to the graphics card or its drivers, even though they are up-to-date? I have not changed the power cable from my old PC; could this be a factor?

Any insights, suggestions, or similar experiences would be greatly appreciated. I'm trying to determine if this is a hardware issue, a driver conflict, or something else entirely.

Thank you in advance for your help.

I accidentally blocklisted Tumblr - and the popup says to go to options, but when I look, there is nowhere for me to remove Tumblr from the blocklist nor can I find the blocklist itself.

I have been using my banks website, www.lbandt.com, for years. Suddenly firefox cannot find the website, what is the problem? Have to have access or can't use firefox.

Thanks

I have reinstalled and refreshed the app many times, but whenever I try to search something, it says "An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR. This happens with every single search on every website, not just google.

I encounter this error only on my.nintendo.com. However nobody else I know encounters this (even using Firefox) and I do not encounter it on Edge browser.

When I open the site it stays for a few seconds, then loads an error page. Then this error page reloads itself every few seconds. I tried to include some Inspect tool details. Before a 404 error there are 303 and 302 responses. I live near my friends who do not have this issue (same ISP too) so it's not a regional issue. In the screenshots the four (and two more further down) red GETs below are all "304 Not Modified" status'd

I'm not sure what type of info I can dump from the browser or how, to help diagnose this. I'm on Windows 11 (though I was having this isue on my dual-booted Linux install too), on version 121.0.1 (see screenshot of About Firefox for more?)

Thank you for your time reading my post, please help me report this with more details.

I'm experiencing a problem when I visit certain websites, like 'https://mui.com/x/react-data-grid/'. Every time I try to access this site, the page starts an infinite reloading loop, preventing me from using the website normally.
