Diễn đàn hỗ trợ Firefox

Hi My computer crashed today and it had to be it reformatted. I have updated the computer but i want to update my bookmarks. How do i access / restore my booksmarks from yesterday? At the moment I cannot see any of my old bookmarks all i have is the bookmarks that come with when you install firefox.

I am logged into firefox but i cannot see my old search history or find any of my old bookmarked folders.

Please help me, I thought firefox was looking after my bookmarks when i was logging in.

Thank you

Louis

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

I have a new PC running Kubuntu 22.04, with Mozilla Firefox 120.0.1 (64 bit) installed. Standard, the system window title bar was hidden. But I wanted access to the "Move to desktop" menu and wanted the title in the title bar. So, in "Customize toolbar" I checked "Title bar". The title bar reappeared, but a complete border along the Firefox window became inaccessible, and when clicking in that zone, it effectively clicked in the window behind. In particular, the complete menu bar is inaccessible, as well as the scroll bar on the left and in the bookmarks sidebar the fold/unfold. And Mozilla Thunderbird 115.5.0 has the same annoying behaviour. Even when hovering over some menus in the Mozilla window, you can sometimes see reactions from the window under the Mozilla window. On older Kubuntu computers (up to 18.04) with older versions of Firefox (up to 113.0.2) and Thunderbird (up to 102.11.0) I do not have that problem. How can I get at the same time access to both the system title bar and the menu bar ?

I've been trying to sign in to pinterest, duolingo, etc using the 'sign in with google' option since my account was saved there. Whenever I click it, a sign in window opens up as usual, but it only ever shows a blank screen. No matter how long I wait, nothing shows up. I tried clearing cache, and it still didn't work. It worked before, but recently since the past 2 weeks, it became like this and I don't know how to fix it.

I have some extensions on my account so I'll list them out just in case one of them is the one making this problem: -Search by Image -Firefox Relay -uBlock Origin -DuckDuckGo Privacy Essentials -TWP - Translate Between Pages -Ecosia

(Below is a screenshot showing what I mean by the sign in window being a blank screen.)

Many complex websites that had no problem till the latest version of Firefox don't load any more with the newest version. If this goes on like this I have to change my browser. I used Firefox now for many years but it looks like I have to change, as there are no problems with other web browsers (Opera, Edge, Chrome, etc).

Aren't there a lot of feedbacks like mine?

SIncerely, Franz

When using the reader view, articles get cut off. A good example is newyorker.com or washingtonpost.com. Is there a setting or two where I can ensure the entire shows up?

Hi,

I am a student, who tend to mass download files at once. The annoying part is that after every download, firefox automatically opens up the downloaded file in a new tap. How can I disable automatically open files after download?

Thanks.

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

When I do a Google search, the icons/buttons for Web, Images, Shopping, etc. do not display correctly. I can only see the tops of the buttons. I tried disabling my plugins but that didn't help. I launched FF in troubleshooting mode and that still did not resolve it. So far, I've only found two ways to fix it. I can either view it in a private window or I can use the User Agent Switcher plugin to force it to Chrome. This is something that just recently started, probably beginning with v119 or even 119.01.

I want to find to get rid of this or find the source of this so I can delete it.

In "about:policies" there are 2 Active Policies: "DisableTelemetry", and "DisableDefaultBrowserAgent" Also, in "about:policies" I'm not sure if it's related, but there is a long list of policies there too.

Today I went to tesco.com site OK, but when I tried to login I got an Access denied message: "You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server.

Reference #18.96421202.1700656983.3e25708 "

I cleared cookies and history and eventually uninstalled and re-installed firefox, but still the massage persists.

MS Edge and Google get me i fine, but I prefer to use Firefox if possible. Can you please suggest a way to prevent the error message.

Thanks

I want to be able to start a live stream in Mighty Networks - all seems to work, except the go live button is blanked out. I tried all the usual up to reinstalling firefox and generating a new userprofile in windows 11 and getting a brand new firefox version running in the new userprofile. With other browsers like chrome it just works fine.

On my latptop running windows 10 firefox does not encouter this problem.

Any suggestions are very welcome, I can of course switch browsers but would prefer to see this issue resolved.

Curious to hear if any other users encounter the same issue,

Thanks for any help provided,

Bart

what triggers the captive portal login... ? It's a great feature on a phone!

I am experiencing it on Linux 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux, Firefox 115.1 (esr?) to 120.0.

Firefox is talking out through a Comcast-supplied router to the outside world and the captive portal attempt is being sent to one of localhost's aliases.

The firewall was setup as ufw disable; ufw reset; ufw default deny incoming; ufw default allow outgoing; ufw enable. The local apache is reporting attempts to access localhost's /canonical.html every 3 seconds. 127.0.0.1 - - [22/Nov/2023:06:10:55 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:10:58 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:01 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:04 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:07 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:10 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:13 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0"

I am on Firefox Developer Edition 120.0b9 (64-bit macOS). Using sites like whatismyip and whatismyipaddress, I am seeing that I have a VPN or Proxy enabled. When I use Chrome, I don't see this. I went through all the settings and turned off anything that could even remotely be related, and still get the same results. Does Firefox have a built in VPN that I am unaware of? Is there a way to turn it off?

1. When I set "NEVER REMEMBER HISTORY" Firefox create an initial INVALID INITIAL http request.

GET /lipsum.html undefined <--------------------- HERE Host: myhost.com User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br DNT: 1 Sec-GPC: 1 Upgrade-Insecure-Requests: 1 Connection: keep-alive Sec-Fetch-Dest: document Sec-Fetch-Mode: navigate Sec-Fetch-Site: none Sec-Fetch-User: ?1 Pragma: no-cache Cache-Control: no-cache

3. This causes a NS_ERROR_NET_TIMEOUT_EXTERNAL

4. Firefox then immediately issues a 2nd HTTP Request, this time correctly.

GET /lipsum.html HTTP/1.1 <---------------------------- Host: myhost.com User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate DNT: 1 Sec-GPC: 1 Connection: keep-alive Upgrade-Insecure-Requests: 1 Pragma: no-cache Cache-Control: no-cache

I have a video of the behavior and a simple HTML file to test with. I can't upload either.

Firefox just updated to version 120.0 I hadn't used youtube for a while. When I tried to play youtube videos none of them will play, only get a green screen with audio In troubleshooting mode they will play Refreshing firefox does not fix the problem

Help! I just installed the latest Firefox 120.0 and I have a huge problem:

I work a lot with the address bar. I type a few characters and choose a URL from my history that I need to work with, then modify that URL by typing or pasting, to get the address I need. Now, I can't do that. Either I accept the full URL suggested or I must type a completely new one. That's a huge obstacle for me. I absolutely need to work with, i.e. select and modify, URLs that I have previously visited.

Please tell me there is a way to do this!

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.

Other browsers and programs manage to use the web just fine, but lately, firefox is hanging for minutes at a time, spinning its wheels, when I try to do anything online. It happens multiple times per hour, for several minutes. No idea what is wrong. I tried everything firefox recommends. Nada. Anybuddy have a clue? About to go back to the darkside, chrome. This is maddening.
