Firefox Support Forum

Hello, (we are using the latest FF) due to technical requirements we share the same Firefox with our children. We use the primary/master password to access all passwords but FF asks for it just once at the very begin. Once we type the primary/master password in FF never asks again what means that our children can use them as well. Is there any setting in FF that will ask for the primary/master password every time we access password protected web page ?

Hello everyone,

I am a long time Firefox user and absolutely love it. First of all thank you for this amazing product.

I run Firefox with "Open previous windows and tabs" selected in my General settings. When I exit/restart Firefox, it reopens all my windows and their tabs. More importantly, it places them in their original desktop workspaces, BUT this only works reliably in Windows.

In Linux I have a problem in that some windows "remember" the workspace they were in, some however insist on reappearing on the "first" workspace.

I use Firefox with GNOME 42 and a fixed number of workspaces. (Gnome now has dynamic workspaces which are a bit similar to Mac OS, but I have turned that off.

Right now I have 6 windows open:

• two of them (L1/L2) are Linux-related and are in workspace 1
• two of them (D1/D2/D3) are Development-related and are in workspace 2
• one of them (S1) is science-related and is in workspace 3

When I exit Firefox and restart it, all windows go back to their respective workspace except for D3 which appears in workspace 1 instead of 2.

Furthermore, if I open a new window (N1) and visit any site, then it exit/restart always makes it reappear in workspace 1.

This is very annoying. I have no idea how L1/L2/D1/D2/S1 have “stuck” to their original workspaces, but anything new I open seems to ignore the workspace it was placed in and insists on reappearing in workspace 1.

Is this something Firefox controls, or is it the role of the desktop (in this case GNOME) to do this?

When I open Firefox through the GUI nothing happens. It acts as if I never tried to open it.

When I attempt to open it via the CLI I get:

joshua@joshua-Z390-AORUS-PRO-WIFI:~$ firefox /snap/firefox/1443/snap/command-chain/desktop-launch: line 52: /home/joshua/.config/user-dirs.dirs: Permission denied sed: can't read /home/joshua/.config/user-dirs.dirs: Permission denied /snap/firefox/1443/snap/command-chain/desktop-launch: line 261: /home/joshua/.config/user-dirs.dirs: Permission denied cp: cannot open '/home/joshua/.config/user-dirs.locale' for reading: Permission denied /snap/firefox/1443/snap/command-chain/desktop-launch: line 266: /home/joshua/.config/user-dirs.locale: Permission denied Error: cannot open display: :0

For context: Ubuntu: 22.04 LTS

The update that I ran was simply generic system updates through the app store. Notably though it was the snap store not the ubuntu software store. Don't know if that matters.

Any ideas? Thanks a million!

Firefox On Linux Persists with a problem that many webpages that are useful,such as wikipedia,youtube or any others crash the browser because for no reason,it returns an error message saying that i have multiple tabs open when there are only 2 tabs shown at the screen at one time,is this normal? i found this out in 100.0.2 and no,some useful websites like troubleshooting or websites with multiple file links for example can still run like they normally would

Hi! Since updating Firefox to 98.0 I've been experiencing sudden performance drops(lags/freezes/stutters) while scrolling. `about:support` page shows that compositing is `WebRender`. The issue occurs with fresh profile without any addons installed and also in `firefox-nightly`(100.0a1). However, scrolling is totally smooth in 97.0.2 and earlier versions of Firefox.

What changes in Firefox 98 could cause this, and are there any settings in `about:config` I can try to tune to solve the issue? These are the settings I've always used, and, as I mentioned, scrolling was smooth before 98.0:

gfx.webrender.all = true general.smoothScroll.mouseWheel.durationMaxMS = 400 general.smoothScroll.mouseWheel.durationMinMS = 200 mousewheel.min_line_scroll_amount = 40 mousewheel.system_scroll_override.enabled = false

Hi all. Did a search but found nothing that helped. Just updated my Fedora 36 workstation and tried to play videos in CNN and MSNBC web sites and get the error message: "Code: 4 | Message: Something went wrong during native playback." I am using the latest Firefox WEB browser. UTube videos are playing fine. Someone has stated on the Fedora forum that they have the same problem but has no problem in Chrome on the same machine. Any ideas? Thanks in advance. Bob BTW, this happened in two machines running Fedora 36 and Firefox 101.0.

I was using Firefox on windows 10 laptop, everything was synced with my account. Now after switching to Ubuntu I can't see my bookmarks, Just an empty toolbar. Now I don't have access to my old laptop, I sold it.

Any help?

I went to settings and set firefox to open links in a NEW TAB instead of a new window, but it still opens links in a new window. I did a search on google and when I click on the link for the website to see the information it is still opening in a new window. How can I fix this so I don't have a lot of new windows. It's irritating to have to close all those stinking windows just to get back to my original window. I just want the links I click on to open in a new tab.

Ok, there might exist a solution to this, but I am not able to find it or even a better way to explain it.

So, the main issue is, I have a lots of tabs open on my Firefox (Linux) and after some minutes of inactivity, Firefox automatically deletes all the data associated with that site.

So, when I switch back to that site, it reloads.

The main issue is with Whatsapp Web, as I don't get notification if I don't switch to the tab every now and then.

There might be a option for this behavior in the settings but I can't seem to find it.

Please help me find a solution.

Thanks

For some time now FF will not open certain sites that it used to, these sites all open and function normally in other browsers such as Opera. The most important being my online bank! I have contacted the sites involved and they cannot understand why. I have cleared Cache, cookies etc. I'm using FF 88.0 on Ubuntu. Can you help?

Firefox 101 Xubuntu 20.04

I want to completely disable the Firefox pop-up notifications regarding updates. I have searched the web for an answer and cannot find anything workable. Can you please tell me how to accomplish this as the constant nagging is extremely annoying.

In about:config I have the following set with no success:

app.update.auto false app.update.download.promptMaxAttempts 0 app.update.elevation.promptMaxAttempts 0 app.update.enabled false app.update.interval 31536000 app.update.promptWaitTime 31536000 app.update.silent true browser.search.update false update false

Whenever I attempt to access DRM content such as netflix or spotify I am notified that the WidevineCdm plugin has crashed. I'm running firefox version 101.0.1 on Kubuntu 22.04, I am running the debian package release, but I had this issue with the snap version too. I've submitted crash reports, but they're all "EMPTY: no crashing thread" (https://crash-stats.mozilla.org/report/index/20af09a5-6bc4-4719-9242-38f5c0220614 here's one).

Hi. Recently, when I open "beisat.com" or "beisat.org" in firefox it shows the website content in a bad shape. I am 100 percent sure that it is not from server because I have tested with my phone and another laptop. Also tried multiple internet connections. I failed to find a way resolving this error.

When opening a new tab externally, e.g. via `firefox --new-tab <url>` or `xdg-open <url>`, Firefox doesn't raise its window.

If this behavior is abnormal, note that I'm using KDE on Wayland (Ubuntu 22.04) with "Focus stealing prevention" off. If it's normal behavior, is there a way to change it?

Hey there,

Since upgrading to Firefox v100 a few weeks ago I've had incessant problems every time I reboot my laptop.

If I leave Firefox running (i.e. I just hit shutdown and let it sort itself out) then next time I boot up, and I try to open Firefox for it to load my prior session, it spawns a new window and just gets stuck forever. If I close Firefox before shutting down, however, it reloads itself just fine.

This has led to several lost sessions and having to restore using sessionstore, either when laptop has died or I've just shut the laptop down without thinking about it.

I run Kubuntu 20.04.

Thanks Chris

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

I can't play a video when logged into a website - see https://support.mozilla.org/en-US/questions/1371380

I'm sure it is not Firefox as I have also tried Chrome and Opera; same problem. How can I debug this and find out why the video cannot be played ?

I see there is 'Remote Debugging' and 'Browser Console' under 'More Tools'. How do I use these or other tools to find out what is causing the problem please ?

I've read through quite a few posts on this error. Disabled the only extension, and followed guidlines on how to disable tracking protection. I still get the error message.

[quote]Firefox Can’t Open This Page

To protect your security, vimeo.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Have tried the 'Open site in new window', it goes to a Vimeo video and then an error message ..

[quote]Sorry, we couldn’t find that page

Make sure you’ve typed the URL correctly, or try searching Vimeo. You could also watch one of the videos below instead./quote

Even though when I hover the mouse over the 'shield' and the display is "Enhanced tracking protection is off for this site", the error still comes up. I go into settings and the 'Managed Exceptions' shows no entries. Shouldn't there be an exception in there for the site I am attempting to view a video from ? There is no method to add a site manually.

Firefox 101.0.1 (64-bit) on Kubuntu (linux)

Hello

I want to open pdfs from firefox (snap 101.0.1) with the default application of the system (Xubuntu 22.04) and not open them in a new tab within forefox.

But it does not work, as if there was a problem with the system handler but only for pdfs and not for other file formats.

More details :

• I changed Preferences/general/Applications for pdfs to use either "always ask" (and then chose "open" " With system handler" when asked) or "default system application". In both cases the pdf is downloaded but not opened. If I right click on the downloaded pdf in the list of downloaded files and then chose "open with system handler", nothing happens.
• Opening the pdf inside Firefox works well and opening pdfs saved on my disk (outside firefox) as well.
• Opening other file format by choosing to open them from firefox with the system handler works well too (tested eg with .torrent, .xls, .tif,...).
• I tried to change the default system application for pdf (Atril) to other softwares without success (Okular, Evince).
• If I try to open a .djvu file with the "system handler" it is opened correctly using Atril which is the also default for pdfs... So Atril works for .djvu files but not for pdfs...
• I tried to replace the handlers.json file from my profile by a handler.json file from a brand new profile, without success (I still have a backup of my old profile file if needed). I did that because opening with the system application worked before and the bug appeared after I changed all applications preferences to "always ask" (and there were a lot of them in my rather old handlers.json file).

I'm lost...
