Diễn đàn hỗ trợ Firefox

Hi!

I am having a problem with Firefox where: - if I am searching in the address bar in one tab (tab A), - but then before that finishes loading, I switch to a different tab (tab B), - Firefox will switch me back to tab A once tab A finishes loading. It's not immediate and is a little aggravating as it pushes me out of what I was already doing.

I'm currently on Firefox Beta (145.0) on Windows 11. I've tried the "When you open a link, image or media in a new tab, switch to it immediately" setting.

When a firefox window is active on my second display, I lose the firefox menubar on my main display. I haven't noticed this before, is it something new, or have I inadvertently changed a setting?

Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).

I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.

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.

Guten Tag,

Im Firefox Developer habe ich seit ca. einer Woche das Problem, das die Lesezeichen nicht mhr funktionieren. Kann weder etwas anzeigen lassen, hinzufügen noch importieren.

Das zweite Problem habe ich heute 07.11.2025 festgestellt, habe einen neuen Tap geöffnet und es werde auf einmal die gespeicherten Webseiten nicht mehr angezeigt.

Was kann ich tun? Developer habe ich gelöscht und wider installiert, auch resettet, doch es geht nicht. Auf der zweiten Firefox Brwoser habe ich zwar die Lesezeichen, doch kann keine Webseite mehr hinzufügen. Auch bei öffnen eines neuen Taps, sind die gespeicherten Webseiten verschwunden.

I do not want my searches to be reflected in the address bar. I believe in prior versions of Firefox there was a checkbox to delete that provision. I'm using Firefox 123.0 64-bit with Windows 10 and have been through the setting and more tools areas but found no way to remove that function. I did try the about:config suggestions but still have no joy.

I am trying to log on to my account at SketchUp. At the login page i hit get started and a black page come up except in the top left corner is typed "Firefox not responding" the page hangs a few moments then it takes me back to SketchUp login. I have not had any recent updates done or required since last logged in and that was yesterday all worked well.

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.

Hi. Strange request I know because Firefox is working perfectly but Google has failed me.

We have a printer/copier in our small club. The IP address assigned is 192.168.1.125. Typing this into a browser should bring up the copier admin dashboard.

When I do this using Firefox everything works fine, BUT when I use any other browser such as Chrome, Edge or Opera I get the "Cannot connect" "Error connecting" etc message.

I removed Bitdefender antivirus and disabled Windows Defender but it's still the same.

Any network people who can point me in the right place as to where to look or report to the correct forum.

Apologies for posting in here when it's not a FF problem.

Thanks in advance TQO
