How do I resolve this issue? I get the message below anytime I try to view my organization's website or when I try to log in to access the back end.What do I do?

I am receiving this on many different websites including CDNs (such as served JS):

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

Please contact the website owners to inform them of this problem.

I verified it occurs in Private Tab mode too, without extensions. It does not occur in other browsers such as Chrome when I test the same URL. Clearing my cache etc does not fix it.

Repeatedly, repeatedly, repeatedly get SECURE CONNECTION FAILED - An error occurred during a connection to xxxxxxxx.com. PR_END_OF_FILE_ERROR Error code: PR_END_OF_FILE_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. There are few attempted web sites that do not get blocked with this message -- EVEN WWW.FIREFOX.COM. I've tried downloading an update to Firefox, but have problems with doing it -- have often gotten the above notice even when trying to download update! Keep getting "Update Failed". Have no trouble accessing any sites using Safari. I'm running a late 2012 21" iMac with macOS Catalina Version 10.15.7

"Error code: SSL_ERROR_RX_RECORD_TOO_LONG"

   This message shows when a spam quarantine program updates in my Thunderbird mail (3 times daily)  Where do I adjust the record length to allow viewing ?

Error 403 forbidden when trying to click on a link for FileOptimizer from OlderGeeks.com. I first got something about security risk and when clicking I accept it then I get the error. Now just goes right to the error 403

When doing a search I receive a message " Secure Connection Failed

An error occurred during a connection to af.xdock.co. SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG"

How do I fix this issue?

I have experienced Error code: PR_END_OF_FILE_ERROR in Developer and regular Firefox. I just downloaded WaterFox and tried opening the same websites and all work normally. That tells me there is a setting in Firefox Developer or regular Firefox that is causing the issue. I have read and tried all of the recommended fixes and none have solved the problems the both firefoxes. I'm sending this thru Waterfox. HELP

Hi, I am working on an extension which fetches my google calendar events and shows them nicely as graphs and summarizes the events. I need a CLIENT_ID in for getting an access token from google (OAuth2). I got one from my google cloud console but I don't think I should push that to the add-ons site.

I am quite new to this javascript/browser world and don't know where to go from here. It would be great if people can just download my add-on and just use it without providing a client ID and zipping it themselves. I asked this question on stack overflow and they marked it as off-topic :_).

So far I couldn't find any information related to this on the web.

I can go to any link I've been to previously and went to Live.com to go to Bing to search. I was looking for a recipe for cherry sauce for venison. I'm on a 2017 Imac that's up to date on IOS and Firefox is also up to date. This was not happening this morning.
