Diễn đàn hỗ trợ Firefox

I've got a really old MacBook Pro that's still running 10.13, and Firefox has started displaying a nag screen telling me that this version is no longer supported, and to install a newer version of MacOS.

Is there something in the advanced settings that will stop it nagging me? I now know it's not going to get any more updates, there's no need to keep telling me every 20 minutes...

(Note to the devs: a "don't remind me again" checkbox would be nice for things like this!)

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

Looks Firefox after recent update can not effectively open youtube.com as well as other webpages that contain video and or sound. Sound can not be heard. on youtube cannot completely finish opening the webpage. In complete transition. Hence the web page freeze or shall I say stuck.

I've tried the F9 Keyboard Shortcut, I've tried other Reader Add-Ons, this function simply doesn't work with Outlook. Either when in the Inbox, or with an opened Email. Anyone else encounter this?

Anyone know of a solution to making this work?

On a VERY side note: Here is my 1st initial text, when I believed the problem was about Firefox Add-Ons (I now have discovered it's not about the Add-Ons, it's the about the Reader View function). << When double-clicking on an Email, on the Outlook web site (https://outlook.office.com/mail/), the Email opens in a new window. When the new Window is opened, doesn't work.

When I click on Firefox's "Enhanced Tracking Protection" Icon and disable it, then the Extensions work. What's even weirder, is the behavior is the same for the REVERSE (if the Enhanced Protection is Disabled, the Keyboard Shortcut doesn't work until I "ENABLE" the Enhanced Protection).

Is there a setting in about:config that can return the functionality of Add-Ons (Extensions)?

On a side note, I found a setting to force the New Emails to Open in a new Tab instead of a new Window. The same bevaior is replicated, No improvement has been shown on that front. browser.link.open_newwindow.restriction = 0 >>

When I enter something in "address line" or "search", Firefox flashes several windows before stopping. If I click on a item, it does it again and does not open the particular item.

I have been a user of FireFox for over 20 years. This morning when it updated, I got the message that this is the last update I'll receive as support for Windows 7 has ceased.

There is nothing wrong with my laptop, it works 100%, fulfills all my needs, yet you seem to want me to toss it in the bin and buy something I do NOT want! I have no interest in obtaining a new OS, I have used windows since 3.1, enough is enough. I have no desire to 'learn' another OS, the one I have is just perfect for me.

How 'green' is it making something that works perfectly, obsolete, just because it is a mature OS?

Not all of us need a cutting edge, super dooper hyper bells & website system. I'm quite happy using FireFox to access the odd email, do a bit of general surfing, and a bit of online shopping.

Why is it so difficult to keep FireFox in use for Windows 7?

Why should we be forced to switch to an O/S we don't like. Vista all over again. These are good O/S Microsoft just money hungary with poor replacement O/S's. Windows 10 and 11 are junk.......................

I want Firefox to be my default Browser... but, as much as I love it, When I'm on Facebook it doesn't let me reply to messages from friends. Apparently hundreds of users have reported the same problem. Has anyone figured this out yet?

Firefox 115 it´s not decoding video and has high CPU Usage specially in full HD video streaming in twitch. I noticed this problem since 114 version. I upload two SS one from Firefox and one from edge.

Im having an issue with firefox where the tabs keep crashing i cant go a day without the tabs crashing 50-60 times or even the browser itself crashing, ive tried relaunching without addons, with troubleshoot mode on, firefox on a different drive but, it is still crashing, i looked at the error logs and if im reading it right (im not at all knowledgeable in how to debug software) it is always crashing at a point where the module is none and the signature is an address value, I put screen shots of the error reports showing the numerous crashes, before I think its a hardware issue like a bad stick of ram (which i dont think cause i ran memtest 86 test overnight with no errors), a faulty motherboard, or god forbid a faulty cpu and start firing the parts cannon at the issue i want to rule out any software angles for the problem.

The solution I had posted here - [https://support.mozilla.org/en-US/que.../1343170] no longer works (Firefox Developer Edition 115.0b9).

Having inspected [https://searchfox.org/mozilla-release.../popup.css] I am still unable to find a solution to remove the box shadow from content area context menus.

Hello- I have just begun getting "secure connection failed" with "connect-reset-error" when I am trying to sign in to any Comcast site (I'm trying to load my email). This started yesterday when I did the most recent firefox update. I am able to get access to the email on my phone, so the issue appears to be with my computer. Thank you for any advice you can offer.

Logins.csv appeared on my desktop after powering on PC. I did not export password data, file just showed up. Is this normal? Related to an update? Should I be concerned about a data breach?

For the past few months, Firefox V 115, will not save bookmarks on any folder except Bookmarks Toolbar. I have gone through the Help sections and have followed the various steps to find, and change, the bookmark files. They are always marked 'read only'. I change them and try to save a bookmark. Nothing. When I restart Firefox, the files are back to 'read only' again. What am I doing wrong?

How do I solve this problem?
