Diễn đàn hỗ trợ Firefox

I just ran "C Cleaner" to clean my computer. At the end, it said to ask the browser if there is a 64 bit Windows compatible version available? It takes 21 seconds to open my browser. That seems like a long time. The message went like this "\??\C:\ Program Files(x86)\MozillaFirefox\firefox.exe" How do I know what version of Firefox I am using?

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

As of last week, I am unable to reply in the reply sidebar in a Slack thread. When I click the reply icon associated with a comment, the sidebar opens and a loading icon is displayed for a second but then nothing happens; all I get is a white sidebar. I have updated to 99, shutdown and rebooted, opened Slack in an new window and nothing allows replys. I am running Windows 10 Pro, build 1903, 64 bit, i5 processor, 16 GB RAM. Suggestions?

When I load Amazon.com, the webpage is a lot of text and random pictures. Amazon's layout is broken. I loaded the same page in Chrome and Safari without a problem. I reinstalled Firefox 99.0.1 without any improvement. Please fix.

when I go to password manger, why do all the websiters look like this? I'm using the built in one..how can I edit it if I cant read what it is.. thankyou Website address moz-extension://3b4a3f36-7056-4eee-bcb3-2b0838fa07e1

The instructions for the Window Titler icon suggest to turn on the Title Bar (with the Firefox icon, usually shows title of active tab, but would presumably show the Window Title if one was assigned). I can't find how to turn it on in version 99.0.1. It's not where the instructions for Window Titler said to look (managing the Menu bar or the Bookmarks bar). Any suggestions?

Would love for this feature (named windows) to become a normal part of Firefox. I wouldn't mind having the Title Bar anyway; at the cost of a few pixels, I would have something to grab onto when moving windows around that wouldn't accidentally do something to a tab.

Hi, I tried to download a script but Firefox warned me it had a virus / malware. So I immediately put it in trash, emptied trash, restarted my Macbook and used Bitdefender to scan my Mac. Fortunately it detected no viruses. So I think I'm good (Hopefully!)

But, every time I open Firefox now, a little window appears at the top showing my last download and telling me it had a virus or malware - I'm posting a screenshot of this. I removed it from my history, and cleared the preview panel, but it still pops up. To be clear, this only happens when I completely close Firefox and reopen it, not when I just open new windows or tabs.

How can I get it to stop popping up with this message? Also - one other oddity, each time I open Firefox, it says the time this script was downloaded matches the time I open Firefox (as opposed to when I actually downloaded the pdf - about an hour ago)

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

When viewing email on Outlook in Firefox, there now appears a rectangular black box over part of every email. This does not occur when viewing Outlook emails on Chrome or Edge. I thought it might be because of my adblocker (Ublock Origin) so I turned it off, but the black rectangle still covers part of my messages (and I have Ublock on Chrome, too, with no problem viewing Outlook).

The rectangle covers only a portion of the messages. When I scroll the message, the black rectangle remains stationary and the message scrolls behind it, thus revealing the portion previously covered by the black rectangle (a different portion of the message becomes covered).

I tried to take a screenshot to show the black rectangle covering part of the message. Amazingly, even though the black rectangle is there when I take the screenshot, the screenshot itself does not display the black rectangle....instead the message appears in the screenshot without being partially covered by the black rectangle.

I am trying to transfer my bookmarks, open tabs and passwords etc. from my old laptop to my new one. It appears I have to do this with Firefox Sync under the preferences menu. However when I try to connect a new device, I am told to open the code scanner on my Firefox App, which sounds like I have to use a mobile? How do I scan the QR code using my new laptop?

Like the title says, whenever I try to zoom out of an image to make it smaller, it causes the image to zoom out very far in just one scroll "tick".

To be more specific, I'm talking about just scrolling (not using ctrl+scroll). An example would be with Piskel.com where you simply use the scroll wheel to zoom the canvas.

Zooming in is perfectly fine, but when I try to zoom out it seems to zoom out by 3 or 4 ticks. On some websites, such as Piskel, it even it zooms the image out all the way making it very small and impossible to see (It does it with just one scroll tick).

My question is if there is a way to change or fix the zooming, making things zoom out more incrementally. (I recently switched from Chrome which didn't have this problem)

I have just seen a clip on Youtube that concerns me. Is Firefox being phased out as a browser? I hope not. I have been using it for years and it is great. Please let me know. Many thanks Anthony

Hi I have been a user of Firefox for many a year, and this is the first tme I've come across an intrusive problem. Since updating to the latest version, I find I can no longer change the icon on a URL shortcut. I had quite a few of them, which helped distinguish (obviously) what I might want to select. That was then. Now, I have a load of indistinguishable Fireox logos which make finding the shortcut I want imossible. On going to change the icons, I find the Website Document tab in properties is no longer there .. while I have Firfox installed. Remove Firefox and the capability magically returns. I have re-installed Firefox in case of corruption, with no change. Before I remove Firefox permanently (which I'd be loathe to do), does anyone know the cause ... or solution or workaround?

YouTube TV won't load in my Mac OR my Windows Firefox.

Error: "Please use the latest version of Firefox to watch YouTube TV on your desktop."

I'm running 99.0.1. Enhanced tracking off. Extensions off.

YouTube support has been no help! Any ideas here?

Thank you.

When I open https://www.washingtonpost.com/ it loads but after a few seconds it goes blank. This started a few days ago and only happens on firefox.

I am developing an extension. I am running the extension locally and I have noticed that it doesn't load on this page (https://support.mozilla.org). Is there some limitation to running extensions here? The same extension works fine in google chrome for this page. It is very important for me that the extension runs everywhere since it's an accessibility extension.
