I have 2 workstations and I use firefox as my primary web browser for both workstations. My office computer gets secure connection failed which is my main computer but I'm able to logon with my laptop computer without any issues. The site is internal which access our monitoring software for wireless. I'm able to access the site via other browsers, Chrome & Edge on my office computer without any issues. Not sure what else I can do to make this work on my office computer since this is the main computer I use. The following is what I get:

Secure Connection Failed

Bonjour, depuis quelque temps je n'arrive plus à me connecter sur mon interface du site https://www.leboncoin.fr/annonces/offres/provence_alpes_cote_d_azur cela fonctionne avec edge mais je préférerai rester avec Firefox. Le bon coin me dit que c'est un problème de configuration. pouvez vous m'aider ? avant cela marchait très bien. merci d'avance, V Paul

When I receive an email that has a link FIrefox opens without any of my settings. This also happens with Firefox pop-ups, which indicate I don't hae certain products, such as Web Advisor, even though I do.

I guess he first question is why a new iteration of Firefox is opened when I already have it running.

Firefox updated this morning and now I have 3 "recent searches" added into the drop down from the address bar. And my frequently used addresses are now 5, I think it was 6 until today. Also the top 2 lines are search with Amazon and search with Google.

Is there anyway to get rid of the new recent searches, and also the search with Amazon and google? I don't want or need either of these "features", just my most used site addresses.

Make amazon and Google search go away and take the "recent searches" with them.

HOW?????

I'm not sure why I get this message: "This site isn't currently available in the EU", but only on my Windows 11 laptop. I don't get the message on my cell phone; instead it goes right to the website. They both use Mozilla/Firefox. here's an example: "https://mail.yahoo.com/d/folders/1/messages/AN6WxktugKP1Zo6E-gXQSGxZLg4." Connection button shows that the site is secure. I have not cleared the cookies. When I select any one of the subjects in the email which are usually local news items I get this response: "This site isn't currently available in the EU." Here's an example of one of the items: "https://www.audacy.com/wwjnewsradio/news/local/michigan-man-guilty-of-making-threat-of-msu-stage-act-2?utm_source=WWJ-AM&utm_medium=email&utm_campaign=WWJ-AM%20NEWSLETTER&utm_content=WWJ%20Daily%20Recurring%20Newsletter&mi_u=1655089&mi_ecmp=WWJ%20Daily%20Recurring%20Newsletter."

The problem is I'm not in the EU and it appears that I might be dealing with a tracker but when I scan the computer there is no evidence of that. Is there something else that might be going on?

Please stop sending me notifications of update available! I don't want to see them a few times/day or even once/week! How can I stop receiving those notifications, even after I've updated my firefox???????!!

I provide IT support for an 80 year old friend. He uses Windows 7 and Firefox ESR. He has Firefox home as the home page. He had 3 rows of icons showing on Firefox homepage. However today the home page did not show any icons when Firefox was started. Since then about 10 websites have been visited but only 2 show on the home page (Settings Home Shortcuts [for sites saved or visited] is ticked with 3 rows specified. Saved bookmarks are still present as are the saved login credentials.

Any ideas as to why the home page 'lost' all the icons? Why are many of the visited sites not showing on the homepage and how can they be shown? Are there any criteria that apply before a visited website shows on the Firefox homepage?

Thanks for any advice.

I want to insert my new IMAP or Pop email box into Outlook. I was already told that this email box@ sophie.johnson@proofreadereditorwriter already exists. I could not get it to show. So I deleted it, and I want to start afresh to install it.

I can't connect to Amazon.com. I keep getting the following error message:

Secure Connection Failed

An error occurred during a connection to www.amazon.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I think this is a problem with Firefox. Any suggestions or should I switch to a new web browser?

I appreciate any suggestions.

I have Chrome on chromebook. I just loaded Firefox for Chromebook it seems to work fine except. When I put it on YouTube and a streaming station that is sharing live like a news station. after a while it will apparently just freeze stop and shut off. Not immediately, but eventually. Chrome on the other hand will play this station all day long and never have a blip. Is there a setting in Firefox that I need to allow this live streaming video to keep playing and a not to freeze or stop thank you

What's with youtube this week? Earlier there were issues with buffering every now and then, which I've read was google to make firefox users change browser to chromium-based one (chromium browsers didn't had buffering problem). But now videos won't even start to play just buffer endlessly. I've read somewhere that youtube changed something on the server side and now third party apps may have problems playing video. I don't have playback issues on vivaldi or chrome but I don't want to switch browser.

Hi, To who it may concern, a big thank you. I am a longtime Linux Firefox user. I had a secondary password, but somehow it has been deleted. I have changed my primary password and I have full access to Gmail, Youtube and other Google pages. My email address has always been the same for many years. It is recognised by Firefox when I type "My account on Firefox" though I am not allowed to enter another secondary email address.

I am almost 80 and not very computer literate.Kind regards,

Patrick Van Niekerk.

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).

Dear Sir or Madam,

Once again, Firefox is blocking my ability to go into X (Twitter). I'm guessing you guys did an update and changed the settings again. PLEASE FIX. Thank you.

Sincerely, Britt
