i’m trying to open blackboard.com but it keeps telling me ( Did not Connect: Potential Security Issue ) some youtube guides say that you can modify the enterprise security roots from *false* to *true* and it will work, but is it safe to do that? and is there any solution the problem?.

For the past couple of months I have been getting the message www.bbc.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR when loading pages on www.bbc.com website. I have done a search on the internet and it seems this is a common problem with Firefox and does not affect othere browesers. I have done what was advice given online but it does not solve the problem. It is getting so bad I may have to start using one of the other browsers even though I prefare Firefox.

In the last 2 weeks (that I know of), Mercari will not appear when I go to it. I just get a blank page. I've restarted the computer, I've turned off the Ublock and Ghostery but nothing. Everything else works fine. I am not very computer adept, by the way. I sell things on Mercari, so I kind of need to access it. I'm not even sure I picked the right topic (website breakages)....sorry if I got it wrong.

I used to be able to access my email with previous versions of Firefox but cannot anymore. When I attempt to sign in it just goes back to sign in page. I have to use another browser to access my email. Is it possible to go back to a previous version of firefox?

I have noticed quite a few websites that will not load on Mozilla but will load on other Browsers. Even turning off enhanced tracking protection doesn't always help. Some of these sites use to load without any issues. The last one finally loaded after I turned of cookie protection completely. This was that website: https://reservations.gplakes.com/FacilityDetails.aspx?facID=4&sd=10/27/2023&ed=10/28/2023

What can I do to prevent this from happening in the future?

We downloaded the New Firefox Browser 119 and now we cannot check check boxes on our webpages. We can check the box for all, but not for individual check boxes on the same page.

as the title states, pages show up all messed up and i have no idea why, already ruled out cookies and extensions as well as the page itself Attachment should provide visual aid to the problem

Firefox 49 says; "The owner of .. has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website. Actually tis is a government site. Almost all helpers advise "enter about:config" then find change "security.enterprise_roots.enabled" from the list opened, and then chance the value from "false" to "true". But, there is no "security.enterprise_roots.enabled" in the list ???

YouTube will no longer load, but only in Firefox. It works in every other browser I have. If I have a DIRECT link to a video page the video itself will load, but nothing else does. I have attached screenshots of the YouTube homepage not loading, the video page failing to load, and then it successfully loading in other browsers. I also attached a screenshot of my plugins. I have no extensions installed for Firefox. My browser has no updates available either it says, and my cookies have already been cleared. Still will not load.

Good evening, I have a problem with the display of bold text on the Wordpress site editor.

I have already contacted the Wordpress experts and we have noticed that the problem does not exist with other browsers and does not depend on the brand of the PC, given that we have tried with different PCs and with different operating systems (Mac and Windows).

The problem really comes from the browser.

How can I solve it?

Can't login to tv.verizon.com. Entering login info produces the message: Object reference not set to an instance of an object. Trying the same login with Chrome works fine.

Should I be going back to using Chrome again?

https://www.nfl.com/plus/replays/

I use the above site to watch replays of the NFL. Upon updating the browser to the latest version, the page no longer loads the video content. It was working fine on the previous version and is working fine using Microsoft Edge. Can you please suggest a resolution?

Thank you

I am facing a critical problem with my website when accessed through Firefox. The browser is not properly loading my website; instead, it cuts off the page and frequently hangs, causing a frustrating user experience. This issue needs urgent resolution as it affects the accessibility and functionality of my website for Firefox users. I am seeking assistance to diagnose and solve this problem promptly.website

When watching a video on youtube using firefox the network speed displayed by youtube is significantly slow that when on a chromium browser in this case edge. I have tried prievous suggestions such as disabling Zero Round Trip Time Resumption (0rtt) and tried in troubleshooting mode, neither have an effect. I have attached screenshots from the same video from each browser.

4 PM, November 7, 2023 EST. The "About" page of all YouTube channels suddenly disappeared, whatever the the login status. A compressed version will show up from a channel's home page when clicking on the site description from its Home page. Make things weirder, ~6:15 PM it WAS visible from the Tor browser but started acting the same. I have no ad blockers, or ANY extension installed on any apps, including Firefox/TOR browsers. Updates to both browsers were made prior to this behavior. It may be Google/YouTube's fault but it's becoming frustrating because I prefer Mozilla's browsers over Edge or Chrome.
