Diễn đàn hỗ trợ Firefox

When I went to watch Tubi TV today I got this error message when I tried to load the video:

"Oops, your web browser is no longer supported. Please upgrade to a modern, fully supported browser."

But only for a few seconds, then it shows

"Sorry, there was a problem loading the video player. Please try to reload the page. If you are using an ad-blocker, please disable it or whitelist tubitv.com If the problem persists, please contact us at tubitv.com/support"

I booted my firefox in safe mode, still get this exact sequence of events. My firefox is up-to-date. Is there a workaround for Tubi blocking content from firefox browsers? Is that what this is? Thank you

Using text boxes such as comment sections in certain sites will "duplicate" the boxes directly over it Scrolling up and down will lock the boxes on screen and leave multiple traces of the text boxes Refreshing the page will remove the boxes temporarily but will happen again Happens inconsistently on multiple websites Site shown under is dcinside.com

YouTube won't start playing in Firefox. No add-ons enabled. The page is fully loaded, but clicking on Play makes nothing.

The fix is to disable "User recommended performance settings" and then disable "User hardware acceleration when available".

The problem is that hardware acceleration is enabled by default. In Edge or Chrome hardware acceleration is also enabled but it won't break YouTube.

This is the link that Fox was reporting difficulties playing on a Mac running Firefox. I just ran it on my ancient imac using an older LTS version of firefox and am not having any problems (nor with chrome)-

Firefox will not display this site properly https://politicalsignal.com/ -- The site is fine in Edge or Chrome

I can log into preply.com with Chrome and Edge, but always have problems with Firefox. I was able to log in once, but after that, I can't log back in.

Recently I had to reinstall Windows, and saw the opportunity to try getting this to work. Installed Firefox, but *before* I logged into Mozilla Sync (so I'm working with a 100% fresh installation with no history of having Firefox installed) I tried to log into preply.com. It worked. Then, I log myself out and try to log in again, and once more, I can't log back in. I'm attaching a screenshot of what I see when I try. Please note -- I have no bookmarks, no extensions, no addons, no browser history. Everything is tabula rasa.

I found this page:

https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords

and followed it to the letter, meticulously, to no avail. I still can't log into the site with Firefox. Chrome and Edge, yes. Firefox no. I only have Edge because I can't uninstall it. I only have Chrome for situations like this, where Firefox doesn't work. Firefox is my main browser, and I really, really would like to figure out what's happening. I can't understand how this problem persists when the browser is freshly installed; I haven't imported one bit of data yet from my sync account.

Can someone more experienced than me please help?

I need to be able to access banks, specifically USB Direct. I can access my credit union but when I try to get my statement, I get a message that I have been logged out due to inactivity.

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

After the latest updates the drm protection prevents any streaming of hbo or prime video content to discord. Is this just a mistake from mozilla's side or did 2 streaming sites decide on same week to start ruining their service for paying customers?

Hello, I did something stupid. I was trying to set up the dark/light theme via cli, and I asked openai about it.

It suggested this command:

echo 'user_pref("lightweightThemes.selectedThemeID", "firefox-compact-light@mozilla.org");' | jq -s '.[0]' > ~/.mozilla/firefox/*.default-release/prefs.js

Which resulted in the following error:

jq: parse error: Invalid numeric literal at line 1, column 11

When I opened mozilla, my profile was reset, and websites won't load (except this one!). They just hang there loading forever. My internet is fine, chromium works perfectly.

So how do I fix this and is there a way I can recover my profile? (Yes I know I should've made backups)

Uncontrollable reloading of pages - 2 urls in past week - currently: https://www.4wdsupacentre.com.au/ - refresh occurs at varying intervals from not fully loaded (less than 2 seconds) to 10 seconds

Using Mac OS 10.15.7 ; Firefox 120.0 (64 bit)

I have been a loyal Mozilla user for many years and it will be a lot of work to to transfer to chrome or edge but continuing problem with camera/microphone access and now this rubbish makes it necessary.

Sorry, keir douglas

On https://careers.usmc-mccs.org/psc/hprd/EMPLOYEE/HRMS/c/HRS_HRAM_FL.HRS_CG_SEARCH_FL.GBL?Page=HRS_CAREERS_FL&Action=U when I log in and go to my page, Firefox will not allow me to scroll and see all of the information whereas Chrome and Edge does. I am not sure if there is a setting incorrect in Firefox or it is blocking an area from scrolling. I added a copy of the screenshots below from Edge and Firefox.

I'm trying to load https://bfjoy.com/ and only Firefox is redirecting my typing of 'bfjoy.com' as an http: website instead of the correct https:

Why is this? I assume DNS but what is Firefox doing to redirect to the unsecured site that other browsers aren't?

I'm running the latest FF under Win7. Seems that whenever I go to the Merriam-Webster (dot) com site, after a few seconds, my disk activity light goes solid, and the FF CPU usage spike to 10-25%. One time, to regain control of my system (because everything seemed hung) I actually had to resort to the physical power-down switch. Obviously I immediately ran a virus scan upon coming back up (scan showed all okay). Now, if I stay away from Merriam-Webster, FF behaves normally. But it's a damned dictionary site. I occasionally will need to use it or stumble into it. I've used MW in the past without problems. Does anyone know what's going on?

Hello - I keep searching for various fixes to this, but nothing seems to work. I have the latest version of firefox. Macbook user. Catalina 10.15 I find that with almost any website that I'm trying to log into, or enter a credit card and other information, the browser does not show these items, pull downs, forms to fill in etc. I'll go thru a whole process of something, and will be directed to click a box or some such that just isnt there. So I move over to Safari, and the entire page loads. I've adjusted the privacy, cleared cache etc. It's like I'm on an ancient browser.

Any help welcome.

What can I do to get my "upgraded" Firefox to display Facebook correctly. Right now, it is basically a blank page. Edge still displays Facebook correctly. Please try to give instructions that a non-expert can follow.

Firefox tells me to close program because Firefox is already running. When I close Firefox then re-open Firefox: same message. When I check Firefox in Task Manager, there are anywhere from 6 instances of FF running and sometimes up to 24. Something needs fixed.

What would cause websites not responding. I have no malware and the cache is clean. Could it be in the properties, or whatever.

Thank you. It's very frustrating.
