I have entered in exceptions for a web page that Firefox continues to block....I have gone through your steps 4 times now...one time out of 4 you actually let the web page through....since then you don't again...what is wrong with your system? as I am not receiving a download link from the intended exception due to the fact you are not honoring it....

I am trying to access certain HTTPS website and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chrome. Any ideas on what could be the problem?

An error occurred during a connection to delta-executorr.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_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 website owners to inform them of this problem.

Here's what I've tried (none of these works):

   DNS over HTTPS turned off
   Uninstall all add-ons
   Reinstall Firefox
   Create new profile and set it as default
   Delete/rename certs.db in the Firefox profiles folder. 

I'm tired fixing errors which become more complex and solutions are written for people who have the time an knowledge to waste fixing these constant issues in FIREFOX, Time to change browser.

I don't know if this is relevant but one of the website that does not work is https://delta-executorr.com/

Hi I keep getting this error on Firefox. I did disable all my extensions prior to this image shown to see if it was an extension causing an issue to no avail. I also looked for an update for Firefox and saw it was up to date. I also attempted to refresh Firefox which was a successful refresh however the error persisted. After refreshing I fully uninstalled Firefox and then reinstalled however the issue persists.

This error is shown however if I refresh the page sometimes the page freezes as if it lost connection and sometimes it reloads as per normal with the video playable.

Firefox has always had problems processing forms. Not every time, just once in a while and that can be so infrequent that I don't see the browser being the issue until I contact support at the company whose site I'm having issues with. This could be processing a checkout form on a site after purchasing an item. This latest incident involves me trying to fill out an open enrollment form for benefits at the 3rd party benefits administrator because I got fired in Nov [along with many others]. I tried to fill out the re enrollment form and it simply went in circles and never completed. The name of the benefits administrator is "bswift" if that makes any difference. You know what they told me when I called and said I was using Firefox? "Well... you should be using Chrome or Edge." Doesn't happen often, but companies know there is a problem with Firefox. In that case, why are there ZERO help articles on this site on the issues of forms? I tried phrasing the question 5 different ways. The last one gave "Found 52 results for ‘forms don't work’ for ‘All Products’ ". If the companies that I call know that Firefox is an issue, and this has been going on for a LONG time, years, then why has this not been addressed? Either by Mozilla, or by someone in the Forums? Not a single one of the 52 results were even close to my issue. I am simply at a lost to understand why I am the only one in the world forms don't work for. I have to stop, move to Chrome, and start whatever it was I was doing all over again. I have been using this product since Netscape 1.0, and was around long before windows or browsers existed. Any insights are appreciated. Thank you.

Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

Just received message, by LIFEHACKER, originally discovered by LAYER X, about "17 malicious extensions across numerous browsers", the list which includes Firefox and is supposedly a recent event outside of the earlier (?) event involving the Malware Ghost Poster in downloads previously cleansed by Firefox. Is this old news or is there more Malware that is 'out there' or that could be on my computer without my knowledge? (I do not download willy-nilly....) Would appreciate valid insight if it is just repetitious/old info rehashed for shock value. Thanks!

AT&T/Direct TV Tech Wizards tell Me that your Web Browser is too SECURE... I pay all my Bills using MOZILLA Web, never have a problem. 2 Months ago I have had problems logging on to Direct TV web site to pay my bill. They tell me its your web site... I even told them that I have no problem logging on to Government Web Sites. Can you help me?

I have a fingerprint scanner and a slot for a security key, but I have never used a security key, either in the slot or a USB plugin.

When I try to go to Gmail, I enter my gmail address, and then Firefox pops up a screen wanting me to insert my security key, and there are no buttons to change how I verify my identity.

I've hunted all around for what setting in Firefox is causing it, but no luck so far. Ideas?

I was using my account for sync my bookmarks, but i hope that was saved in my phone. After check CCleaner deleted all from my laptop, i realize that was also deleted from my mobile. ¿How i can recover all my bookmarks that was sync in my account?

Steps to Reproduce: 1. Launch Firefox (and add Sites shortcuts) 2. Do not navigate to any website 3. Observe network activity using Process Monitor or clash verge

Expected Behavior: - Opening about:home should not establish TCP connections to remote sites unless the user interacts with them.

Actual Behavior: - TCP connections are observed immediately to sites listed in Top Sites shortcuts, even without user interaction.

Notes: - Disabling DNS prefetch, speculative preconnect, and predictor settings does not prevent these connections. - Extensions have been ruled out, I can distinguish darkreader.org(extention) mozilla.org(update) and reddit.com(your sponsor url) from *.edu.*(my shortcuts), DON'T mention that. - Connections occur before any page navigation or clicks. - I suspect that Firefox may attempt to load site icons (favicon / tile thumbnails), but this is unconfirmed.
