Firefox supportforum

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?.

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.

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.

My Firefox (just updated to latest version) will not show videos from Ring.com. This has been going on for over a month and spans several version releases. However, I can get other browsers (Safari, Chrome, Vivaldi) to view the videos. (I am using a Mac, latest operating system.) I have just been trying to view a video from my Ring account for the last 10 minutes and it will not load and show.

Can you help?

When I select an item in an amazon page I get script that is overlay on the page. In my cart i get this message ML Parsing Error: junk after document element Location: https://www.amazon.com/Phlizon-Spectrum-Upgraded-Dimmable-Seeding/product-reviews/B08GCKPBSQ Line Number 20, Column 1:<link rel="stylesheet" href="https://images-na.ssl-images-amazon.com/images/I/21Yr8ohNIxL.css?AUIClients/QuantitySelectorAssets" /> ^

Hello, I am using firefox 83.0 and I don't want to update it (Why? Because I've an old PC with poor hardware and the playback of online videos is lagging/shuttering in releases after 83.0)

BUT firefox 83.0 doesn't support private fields which make some webpages unable to be loaded. the private fields was supported starting in release 90.0 and I'm using 83.0

So, I need a way to make firefox 83.0 support private fields, Is that possible? Is there a certain files should I edited or replaced to make it support private fields?

Any ideas would be appreciated.

I use firefox on my mac to connect to the webgui on proxmox and casaos. Up until the recent update everything works great. Now, however, all I get is a blank screen with no activity. The same bookmark works great in safari and brave browser. I tried deleting the cache and reloading everything as well as the certs related to the websites. I even deleted firefox and reloaded and got the same behavior.

Doesnt happen with firefox on my linux or windows machines, only the macos. Doesnt happen on other browsers but I would like to keep using 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?

Hi, Mr. or Mrs. The website has blank pages (page cannot be accessed). Utilizing https://xnxubdvpnbrowser.online/ The page is blank even though it looks like it has been contacted at the upper left. Is there a reason Brave is unable to load the website correctly?

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

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?

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 have friends who can access the content on this page https://www.johren.games/games/taimanin-rpgx-extasy-zh-tw/play/ and I cannot find what i need to update or block to get it to work. I have stopped my adblockers. It was working last night Oct 24th for a bit but now it doesn't anymore.

my connection to the internet drops and I receive a message that says "No Internet Connection". This happens frequently at home, and at work and has been going on for months. I will generally close Firefox and reopen, then it says that Firefox is still running and do I want to close and I click yes. I still have a good signal in every case. It mostly happens when I have my email open and another site, like banking, subschool, or doing some type of research. I use chrome for some apps, but I don't like using it but they don't work in Firefox, and I never get a crash notice. I have checked for updates for WIndows 10, ZoneAlarm, Firefox, and drivers and everything is up to date. Other than that I can't find any more information or posts on this. Please help Ronald Fisk

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.

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 ???
