Diễn đàn hỗ trợ Firefox

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?

i accidentally refreshed my firefox and ii got my profile back .. but i accidentally deleted it .. after contacting a local wizard and going on a quest i found my profile sitting in a dark corner of my drive.. it seemed to all be okay but i saw my awesome theme was gone !! after checking to see if i still had my awesome extensions they were ALSO GONE !! everything else is here though like my passwords and stuff.. where are my extensions and awesome seal theme !! im scared and alone !!!! help me mozilla helpers !!

I know it takes just two mouse clicks to open the About dialog, but I'd like to bookmark it so when I check my daily bookmarks by right-clicking a folder and clicking "Open All Bookmarks", it would be displayed. This would be a convenient, albeit forceful, way to keep Firefox up-to-date. The About dialog isn't modal, so that shouldn't be an issue.

Sorry for my language.

The latest versions of Firefox 141 (and 142 beta 1) do not allow the Windows taskbar to appear when I move the mouse to the bottom of the screen. This happens on Windows 10 with the auto-hide taskbar setting enabled. In previous Firefox versions, this worked fine (except for one older version where it briefly broke). I’m not running Firefox in fullscreen mode, and I have no modifications or themes that could interfere. I tested this on a fresh, clean installation of Firefox — the issue still occurs. After downgrading to versions 140 and 139, everything works correctly again. Interestingly, I also tested the Firefox 141 Release Candidate Build 1 from here: 🔗 https://ftp.mozilla.org/pub/firefox/candidates/141.0-candidates/ In that version, the issue only occurred in private browsing mode. Could someone please help me resolve this or confirm it as a bug? Thanks in advance!

Hi, I hope you are doing well.

I have been having issues since this morning. I am unable to open a new tab in the Firefox developer edition.

I have attached screenshots. I have tried to reset settings; I have tried to uninstall and then install again, but nothing works.

Firefox seems to forget edits made to text boxes. I was reading a large pdf and adding notes to previously made text boxes. I thought I must be going crazy as I saw there was no notes I thought I had already made multiple times so I tested it. I edited a text box, scrolled a bit and continued browsing on another monitor. Checked in a minute and boom edit gone. If anyone has a solution I'd appreciate it as I have been using Firefox PDF editor for a bit and quite liked it until now.

When Facebook creates passkey Firefox asks for an USB to be inserted. I have tried to disable USB in the settings ("security.webauth.webauthn_enable_usbtoken","false"). But then Facebook just gets into a retry loop and I can't create the passkey. I use Windows 10, and USB is NOT enabled as an authentication option. I need to fix this as Facebook nags me (in e-mail) to create a passkey.

When playing any Ren'Py web build on Firefox Windows, the frames freeze while entering inputs. Depending on what is being displayed on screen, sometimes it will still continue despite the mouse movement, but most things just completely freeze up. Once the inputs stop, the frames will skip ahead to where they should be. This only seems to happen on Windows, as I was told it is not repeatable on Ubuntu using Firefox. This is also not an issue on Chromium based browsers.

I have display problems with Beta 127 (b4) on a Windows ARM PC (Adreno 685 GPU). FF itself and websites. Version 126 and later runs fine. These errors do not occur when hardware acceleration is switched off!

For months now I can't cut and paste if I use Firefox. I am not remotely interested is uninstalling a heap of adds in a vain attempt to fix the issue. I can use Google chrome and Wonderfox which don't suffer this issue. I fail to understand why Firefox is alone in this problem. I would switch to Wonderfox as a default but it only works on SSL sites. Please stop ignoring this issue and fix it. Running Windows 11 fully updated on an AMD cpu.

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

Up to 126.0b9, files with encoded URLs in their filenames downloaded normally. As of 127 onward, however, it gets changed to _3A instead of %3A, etc. Is there a setting somewhere in config to revert this?

Example:

Supposed to be: test [sound=https%3A%2F%2Ffiles.catbox.moe%2Fe547nk.mp3].png Downloads as: test [sound=https_3A_2F_2Ffiles.catbox.moe_2Fe547nk.mp3].png

Hello! After the recent update, any text I insert remains without spaces and all words are written together. I disabled all extensions: no result. The problem did not occur in other browsers.

In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.
