When using picture in picture on Prime Video, my subtitles aren't showing up in the window, but instead on the original page, despite prime video being one of the original supported websites. Any ideas on how to fix?

I have always been able to connect with Navy Federal Credit Union for my banking until a few days ago. Every time I click on the accounts shortcut I get the FAILED TO CONNECT window. I can open my e-mail and ALL other websites. I can connect with Goggle but I've always preferred and used Firefox. I have used Firefox as my main browser for many many years. What is the problem??

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

Anyone experiencing issue with YouTube on Firefox - I am not able to select suggestions on YouTube search using up/down arrow keys - On Ubuntu 22.04 - Firefox 124.0.2

I have a website that I host. It is behind a proxy. It is a resolvable FQDN with DNS hosted by a major provider. The issue is when I browse to it via Firefox 124 it eventually errors out with connection reset, however if I open a private window it goes right there. I have tested other browsers and it works fine with them (Chrome, Safari, Vivaldi). I thought maybe it was plugins so I tried shutting off plugins one by one restarting after each one and that did not help. I tried in safe mode and could not get there. So I backed up my bookmarks and wiped out the directory and all for Firefox and tried on a fresh directory and that did not work except in private window mode.

Hi there, my name is Alvimutmex. Every time a webpage loads with the Mozilla browser, a "not supported" message appears. Upon examining the settings, I found that Mozilla has to be updated. Would you kindly assist me with updating Mozilla? For example, I receive an error notification when I try to open (https://pdfmedicalbooks.com/).

For about a week now YouTube doesn't display correctly. No content shows. I can open private browsing and works fine. Also works fine on other browsers just not Firefox.

I'm on an iMac running Firefox version 124.0.2 and I've tried disabling all add-ons but nothing has changed to the browser so shouldn't cause any issues.

Any help?

I installed an OBS plug-in for a virtual camera so that I could film my screen and pretend it's a webcam. I was able to use the virtual camera or my webcam on spelltable.com by selecting either from the dropdown "allow" menu. One day, I was no longer able to select my webcam. I could only select the obs virtual camera. I switched to MS Edge which worked as normal. I've uninstalled OBS and all plug-ins. Same result I've reinstalled firefox. Same result. I've been using MS Edge for websites that need my camera.

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?.

Hello guys, so in the past 2-3 days i started facing Cross-Origin Request Blocked for a lot of websites lets take chatgpt for example, if i visit it i get:

Content-Security-Policy warnings 2 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9. (Reason: CORS request did not succeed). Status code: (null). The resource from “https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9” was blocked due to MIME type (“text/plain”) mismatch (X-Content-Type-Options: nosniff).

and its getting so annoying that its blocking a lot of websites, i tried chromium it works fine and works awesomely no cors no problems. I even tried to disable the firefox protection, dns over https on/off, change my main dns upstream, installed firefox developer, compete uninstall/reinstall, cache clear from installers and from firefox it self nothing is working. I will provide firefox developer edition troubleshooting information but keep in mind it doesnt work on both firefox normal and developer

Please any help would be appreciate it.

Firefox v124.0.2-1

I have had to migrate many sites to another browser because Firefox won't load them. That is the error that appears.

I want to use Firefox, but am frustrated by the failure of various fix attempts to solve the problem.

Please help.

Error Message: "Could'nt Sign You In: This Browser or APP May not be Sscure 1. Happened to Both Build 124 and 125 2. Virus Clean 3. Haved tried cleaning the cache and cookies

Hello,

I was trying to watch Youtube and pulled up the page, but all that was there were grey boxes where the recommended videos should be on the home page. When trying to search, only a blank area came up. When I tried to go directly to a channel, the same happened. Loading a direct link from a video let me play the video, but everything around it was gone, no recommended, no channel, no likes, nothing.

I have tried clearing the cache and cookies. My Firefox version is up to date as of right now. I restarted the browser several times and restarted my computer.

Other solutions suggested going to about:config and changing image.webp.enabled to true, but when I search under about:config, that option is not there.

Youtube works if I open a private window and sign in. I have tried opening Firefox in troubleshooting mode and this did not solve the problem. Any help would be greatly appreciated.

Safari has no problem with https://meijer.com, but Firefox flags it as untrustworthy and won't let me connect. I am using Avast! antivirus. Brave browser also works. I am using 124.0.1. I see there is a 124.0.2. I'll try that next.

When composing emails in Gmail holding down a (any) key does not activate key repeating.

Also, the there are irregularities when using discover.com in Ver. 124. When editing my customer profile, keystrokes are not recognized. Nothing happens when typing. I also had difficulty signing-in; this may be coincidental.

Things tried: (1) A different keyboard. Same results. (2) Firefox version 122. The key repeat function worked in Gmail. I could edit my profile at discover.com. (3) Uninstalled and reinstalled ver. 124. All problems persisted. (4) Ran Ver. 124 in troubleshooting mode. All problems persisted. (5) Launched newly downloaded versions of both 122 and 124 (from command line) and ran them simultaneously. The problems persisted in 124 (troubleshooting mode), but 122 worked well. I used two different keyboards with no difference noticed. (6) Downloaded and ran Chromium. All worked well.

If I am on Google Chrome and I type in a twitter post, words that are spelt incorectly are underlind in red... however FireFox does not do this, so I end up posting with many spelling mistackes. How to make it check spelling? If it cannot, I uninstall and go back to Chrome.

When I put the address "https://store.google.com/product/fitbit_charge_6?hl=en-US&source=sh/x/srp/wr/m1/1&kgs=9049baa04a7bf560" into Firefox and hit return, I get no response. Literally nothing.

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.
