Diễn đàn hỗ trợ Firefox

On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

After a update my browser was running very slow, I'm not sure what I did but my whole browser, including history and bookmarks and add ons reverted back years. But I have a whole folder of Old Firefox Data which is from today.

How do I get this back on there and get everything back to normal?

My chat sends garbage. Here I type 'test' to my son. Here is what my chat shows after I press RTN:

I keep getting signed out of my Google account whenever I close Firefox. I switched the Enhanced Tracking Protection to Standard, and I do not delete my cookies when I close Firefox. I even tried to disable the Purge Trackers option but this didn't help either. I have some dev-tools extensions installed + Adblock and Decentraleyes. It does not solve my problem if a disable them too. Would really appreciate anyone's insight.

I have a problem on YouTube where videos are too bright, but when i click for example to save that video to watch later it has normally saturated colors. And I'm using windows. On photo example1 video is too bright, but on example2 it is normal. thanks for help

I'm having an issue that seems to Lock up YouTube on Firefox.

I'm trying to get back into using Firefox but I'm having a persistent issue in both FF Mainline and even in FF Beta 119.

If i play a Video on YT then switch tab to do something else then go back to YT it lock up the video window. I do not have this happen on Chrome or Edge.

I have tried refreshing the browser and still have this issue.

I'm on Firefox Developer Edition 119.0b9 (32-bit) and Windows 11 Pro 22H2 but I've been experiencing this problem a lot longer ago even before upgrading to Windows 11. The first thing I open in my computer is Firefox, it gets the window itself quickly but the page stays blank with the gray loading dot going right and left for nearly 10 minutes before the page loads and Firefox works normally. I don't experience any issues while browsing the internet after that long loading but it's really annoying especially when I'm in a hurry and I don't have 10 minutes to stare at a blank page.

I switched to Firefox DE because I wasn't able to install 3rd party extensions. Just now, my middle click isn't working. I can't use the middle click to open/close tabs and to open links in a new tab. I checked my settings, tried a new profile, nothing works except in normal Firefox, the middle mouse does work, but I don't want to switch to that. My middle click also works in Edge and other apps, but please fix this issue as soon as possible. Thank you.

PS. Please add biometrics to Firefox, like how Google did with Chrome.

Hi Team,

After updated to latest version of Firefox - 118, we facing with this issue: Dynamics 365 App required sign in again and again to use. We need to click on sign in at least 3 times, but no need to provide the credential.

Checking the network log, seeing this: error_description "AADSTS700084: The refresh token was issued to a single page app (SPA), and therefore has a fixed, limited lifetime of 1.00:00:00, which cannot be extended. It is now expired and a new sign in request must be sent by the SPA to the sign in page. The token was issued on 2023-10-09T07:45:27.2163809Z.\r\nTrace ID: 07fa536f-3cd8-4f91-9950-66dc69928b00\r\nCorrelation ID: 594b0d6f-0dab-48e4-900d-f92b8a382eba\r\nTimestamp: 2023-10-11 08:46:36Z"

With a recent update of Firefox Developer Edition to version 117.0b9 i keep getting extremely annoying popups on all sites, asking me if I want to translate stuff.

I don't want to store unnecessary settings in my browser, related to exceptions to websites/languages that I want vs. does not want to translate.

I want to completely disable translations, globally. Forever. Two questions:

- Why there is no "disable translations globally" checkbox in the newly added popup? - Is there an about:config hack to do disable translations globally, for all languages, for all websites, and forever?

thanks in advance

My Firefox has got inconsistently large font size in some UI, namely on the homepage (text elements with style "font: caption") and texts in the Update Firefox notice box (which I don't know how to reproduce within a resonable time and effort). It just happened after a ordinary restart of Firefox: no updates etc. I tried updating Firefox after that but to no avail. How can I fix it?

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

The "font family" property does not change the font of the "option" tag if the font is not installed locally on the computer. I am using Firefox Developer 118 (0b9). Are there any solutions to the problem?

EDIT: I've solved it by installing Kaspersky's extension. I have been troubled by an issue that every time I perform a search on some websites, the page will first freeze for ~10s, during which I can't click on anything on the page. However firefox itself is not totally freezed, like I can switch tabs without any issues, but if I click on the icons of extensions (such as my adblocker) it won't give me any response. After the freeze the page started to load normally. I have tried disabling all extensions, reinstalling firefox, updating to beta, and disabling security.tls.enable_0rtt_data, but none of these works. Other browsers on my device work normally, including Edge and Chrome. Websites that freeze during a search: Google, Bing, Musescore, Duckduckgo Websites that DO NOT freeze during a search: Github, Youtube, Twitter I have encountered this issue both on 117.0.1 and 118.0.

On some sites like youtube, crunchryroll, and other sites usually where it's main purpose is to play videos my sound plays fine. However, on other sites like osu's website, chess.com, duolingo, and others, there's no sound at all. I've tried refreshing, restarting, running in safe mode, and even reinstalling the browser but none of it has worked. My tabs are also not muted. Does anyone know how to fix this?

A setting I would like to change in both Firefox Beta and Thunderbird Beta is "grayed out" and has a lock next to it preventing change. What configuration file(s) do I look for to find where they have been locked, so I can unlock them and change the setting? Thank you.

I am developing a website (using AstroJS, but i don't think that's the problem) and since yesterday I am experiencing issues when opening devtools. Once I open devtools the whole FF tab becomes unresponsive, I cannot even refresh the page until they are done loading. I can change devtool tabs from 'inspector' to 'console' to 'network' etc but especially 'network' and 'debug' tabs are blank.

I run a 'performance' capture and got these results. In the test I have only opened the devtools and switched to the inspector tab which is unresponsive. The CPU usage is at around 90% however, I don't really know how to read the finding and understand what the problem is.

So anyone that can help me understand what is going on here?
