I-Firefox Isithangami Sokwesekwa

In our organization we are using a firewall which has an Intrusion Prevention System. The IPS has a certificate which must be imported into the browsers to be able to load SSL websites. This allows the IPS to inspect the contents of secure packets for any malware or viruses. The problem is this isn't working very well with Firefox. Most secure sites bring up one of the following errors:

Secure Connection Failed The connection to <website> was interrupted while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

OR

Secure Connection Failed An error occurred during a connection to <website>. SSL peer rejected a handshake message for unacceptable content. (Error code: ssl_error_illegal_parameter_alert) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Does anyone have any suggestions on how to get Firefox to work in this environment?

Firefox on mac osx with automatic updates for OS and Firefox up to date for over a year recently started producing failed downloads (probably between 9-13 and 9-14, around the time of the last Firefox update). What has been tried to fix this: everthing from the Mozilla help pages “What to do if you can't download or save files” asserted to be based on information from “Unable to save or download files (mozillaZine KB)” with the exception of dealing with the "plist" file since that could not be found in this OS installation. If anything has changed through these efforts, it has been to cause the failure to be more severe. Before attempting any fixes, the downloads usually produced a zero-byte file of the expected name and an apparently full-length download file with the expected name and a ".part" extension (or an abbreviated download file with a jumbled alphanumeric name and ".part" extension). After all the fixes were attempted, with the additional trial of patching the profile from TimeMachine back-ups well before the initiation of the problems, and then a final effort of a complete Firefox re-install (freshly downloaded via the separate account on the computer then Firefox removed prior to a fresh install), downloads now fail for that one problem account producing only the zero-byte file of the expected name and no ".part" files yet seen again. Created new profiles in Firefox under the same computer account inherit the same download problems (tried twice).

FYI: in addition to the troubleshooting information below, the computer account with the Firefox problems reports another four plug-ins (Blue Jeans, RBlue Jeans and "install" for both). As these do not show up on this computer account where the Firefox browser has no download issues, this may matter. But since the download issues were independent of Safe Mode operation for Firefox, presumably the plug-in differences would not matter.

Hello,

I have already read the same type of question and try the solutions proposed:

Clear the cache and remove cookies only from websites that cause problems.

"Clear the Cache":

   Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now" 

"Remove Cookies" from sites causing problems:

   Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies" 

Start Firefox in safe mode -- still have the same issue.

With other browser Chrome the same issue.

Trying to access other website to buy tickets I have more or less the same issue:

403 Forbidden

You don't have permission to access / on this server.

I have also tried with use system proxy settings / No proxy

Still the same issue.................

What it can be? How can I solve this issue?

Thanks in advance.

Kickass Torrents is a very popular torrent site, yet I find suddenly that it is blocked by firefox as a potential phishing site. This does not bode well for mozilla's reputation for supporting an open internet and freedom of choice. I found no way in the settings to even add or delete an individual exception to this site-blocking feature without completely disabling the blocking of attack sites and web forgeries.

Hi,

I just upgraded my mom's PC to Windows 10. Everything went well but after the upgrade only Windows Apps such as Edge can access the Internet, nor Chrome, Firefox or Avast can access the Internet.

I've of course checked Windows firewall, but everythings looks fine.

Please, help me - what shall I do?

Thanks in advance.

I have low vision issues, so would like to override the color of visited and uninvited links on all pages. However doing this breaks the display of many pages. I did not change any of the fonts, and I allow pages to chose their own fonts. But I still can not override link colors. Is it possible change these colors without breaking most web pages?

I've started getting a 400/Bad Request errors on various sites. I'm running FF 41.0. I cleared my cache/cookies, and it helped a little but still having issues. Some sites that don't work will work if you type the site differently. Some examples:

Doesn't work: www.youtube.com/ Works: https://www.youtube.com/

Doesn't work: Searching for anything in Amazon and this link http://www.amazon.com/Walking-God-through-Pain-Suffering/dp/0525952454/ref=tmm_hrd_title_0?ie=UTF8&qid=1418587605&sr=1-1 Works: This link for some reason and some others http://www.amazon.com/gp/product/1594483493/ref=gno_cart_title_0?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

Any ideas?

First, repeating my original issue: I have a Mac, OS 10.6.8 (Snow Leopard). I can access my Hotmail "Contacts" page using Safari, and at one point it seemed I could with Firefox. Now, I can still get to my Hotmail account with Firefox, but not my "Contacts" page. When I try to, I get this message:

"This page is temporarily unavailable. We're sorry, there was a problem showing this page. We experienced some technical difficulties retrieving the content."

Although I had my OS restored a few days ago, this problem may have existed before that, but I was using Safari, so I may not have noticed it.

Please use layman's terms--I am not tech savvy.

The response from Mozilla was to clear my cache and cookies, but they clear automatically when I exit Firefox. Then there was advice to start in Safe Mode--that sounds more like for a PC then a Mac. I had this very problem last year when I could access my contacts through Safari, but not Internet Explorer on my PC at work. After a few months, IE suddenly connected to my Hotmail contacts, WITHOUT MY DOING ANYTHING. COULD IT BE THAT THERE IS SOME KIND OF DISCONNECT BETWEEN FIREFOX AND HOTMAIL, THAT HAPPENS AFTER GET INTO MY HOTMAIL ACCOUNT, THAT WON'T LET ME GO TO MY ADDRESS BOOK? CAN SOMEONE CHECK ON THIS, SO I DON'T SPIN MY WHEELS TRYING TO SOLVE A PROBLEM FROM MY END, THAT NEEDS TO BE SOLVED INTERNALLY THROUGH FIREFOX/MOZILLA?

I have users trying to download firefox updates, but they are being blocked by the proxy. If I whitelist download-installer.cdn.mozilla.net. Will that give users the ability to download other installs like add-ons?

Every day around 9:30 PM, browsing the web becomes impossible. nearly every site I visit brings up a This Connection Is Untrusted page. I have tried using different browsers and Different Devices. Even my 3DS doesn't work. This has lead me to believe that the problem is either with the modem or my service provider. I checked the certificate of Google via chrome://pippki/content/exceptionDialog.xul, and it read ISSUED TO Common Name (CN) security.frontier.com Organization (O) security.frontier.com and when I checked it now, it reads ISSUED TO Common Name (CN) www.google.com Organization (O) Google Inc I don't know what fixes this problem since the problem stops at different times. It started around when I installed AVG, so I tried uninstalling it, but the problem didn't stop. While I'm fairly certain the problem isn't related to Firefox, this is one of the sites that I am able to visit when this problem occurs. I have tried manually adding the exception so I could bypass the Untrusted Connection page, but the page never loads and the next time it happens, the page is there again anyway.

Whenever I try to access the costco photo center site it will never connect, just a chronic spinning wheel. All other browsers can connect, including the firefox private browsing. What is wrong with the standard firefox browser and how do I fix it?

Since upgrading to Win10, I can no longer sign into Amazon or several https websites. I've checked all the usual stuff and nothing works. What could be causing this?

Last week I downloaded Windows 10. Since then my Internet connection has slowed from the 30 mbps I pay for down to 1 mbps. I have made sure all my drivers are up to date, updated and performed a full scan with my anti-spyware/anti-malware software, and performed all the disconnections of sharing that I can think of. Is there some way to restore my Internet speed? This is regarding Wi-fi speed, and all other devices in our home on Wi-fi (which are still on Windows 8) are performing at full Internet speed.

I was using Firefox ESR version 52 just fine for many weeks now. Suddenly, upon restarting my computer just earlier today and opening Firefox again, it automatically updated to Firefox version 6.0, which is inaccessible with my version of Jaws For Windows (16). I am aware of more recent Jaws updates, but I am content with Jaws 16 and do not have any plans of updating anytime soon. Could a contributor please provide me with a hyperlink to where I can download the "true" Firefox ESR version 5.2? I found a Firefox-oriented page recently, but even when I specifically select older version of Firefox version 5.2, English, Win32, it automatically gives me the neweversion instead. (By the way, upon installing it, I did go into options and select the box that says "ask me to update but don't do it automatically") Thanks in advance.

For the last at least 25 releases, FF has gotten continually more hostile to someone like me who is visually impaired. I had read that FF was going to stop using the hamburger for menus because screen readers couldn't process it. That has not happened. Hamburgers, paper airplanes, icons instead of text, triple dots, and selector switches to turn settings on and off are all anti-accessibility. I don't like any of those features anyway. What is wrong with words like, "Menu," "Submit," or "Send"? This has been getting worse and worse over time. I don't know if the developers for FF are simply oblivious to the problems that they are causing or if they know but don't care. Gmail is worse but it seems like FF is following Google. What a horrible thing to do for accessibility, among other things. At least, though, Gmail on my phone can use the pinch technique to make the text larger. Firefox on my Android phone will not allow that. I cannot enlarge text in any window in the native FF phone app. This anti-accessibility is to pervasive it seems deliberate. Why is this being done????
