I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

FF version Extended Support 115.70esr (64bit) I have set /General/Startup/"Open previous windows and tab" - FF does not restore. It worked as expect before I upgraded opsys (Opensuse15.4 to Opensuse15.5).

Please note: I AM NOT TRYING TO RECOVER FROM BEFORE THE UPGRADE! I am trying to get FF working normally (for me) with my usage and history SINCE the upgrade.

After reading https://support.mozilla.org/mk/questions/1407888 I believe I have tried everything there. FF sometimes restores one single historic tab, sometimes it comes with with one single tab opened to my default page.

1) "sessionstore.jsonlz4" did not exist in the main profile dir. (It does not because I followed instructions in the link above to copy it there and try again).

2) I do have a session file, found in sessionstore-backups dir , displayed with this recommended online converter/translater "https://www.jeffersonscher.com/res/scrounger.html"; it shows the expected windows and tabs.

3) Starting after copying the "sess...jsoniz4" file into the main profile dir, I get one window with one tab displayed; I had about 4-5 windows and 15-20 tabs open when I last closed FF, although when doing research, I often have a 10-dozen windows with 100+ tabs.

4) The History menu does not show a "Restore..." option at all. In the window that did open with a historic tab, the History/RecentlyClosedTabs contains a list of plausible sites, about 10, which may be correct for that window. But there were certainly many that were actually open at the time I shut down FF and the window has only opened one.

Thank you for any help here. Rufus

I'm using a Hotspot provided by Cisco in a library and when first connecting to the Wireless network, Firefox prompts me to login to network in order to have Internet access (expected and works fine). However, once the time session expires Firefox will sometimes prompt again to login. When this fails and internet access is abruptly ended, I've to reconnect to the Wireless network and have Firefox prompt to login.

This is a security vulnerability as someone could advertise the BSSID of the router and have victims connect to their Hotspot instead of the true one.

I'm installing a Docker service set onto a new Ubuntu system, that has Firefox installed by default. One of the services is a GUI application.

However, when opening Firefox for the first time, a dialog shows up that I would like to disable (attached).

How can I disable this?

I'm running Firefox using: "/usr/bin/firefox --kiosk http://localhost"

I've already followed a lot of the suggestions in here: https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs (and verified they are indeed set after installing my own "user.js" file), but I cannot find an about:config preference that disables what I'm still seeing.

Any help or ideas?

Intermittent Master Password Recognition Issue with External Keyboard on Firefox for Ubuntu

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

    • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

    • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

    • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel

PDFs are shown as empty pages after suspend/resume on linux

Hello, I'm using a document management system (SeedDMS for those who know) through Firefox 122.0.1 (64-bit, canonical 1.0, downloaded from packages.ubuntu.com for focal, running on Debian Bookworm, kernel 6.1.0-17-amd64/Debian 6.1.69-1 x86_64, X.Org X Server 1.21.1.7, KDE Plasma 5.27.5, KDE Framework 5.103.0, QT 5.15.8, i7-5820K, GeForce GTX 1070).

Within this document management system pdf.js (v4.0.379) is being used to preview/view PDF Documents. After starting Firefox the PDF view inside the DMS works fine until I suspend (to memory) and resume my machine. Regular HTML-content looks fine but the resumed DMS session shows only blank (all white) Pages inside the PDF view. Changing to a different PDF file doesn't help. The number and size of these pages is presented correctly. I can even select and copy (invisible) text from these blank PDF pages. The problem applies to all PDFs, whether they're single or multi paged, have images inside them (like with PDFs from a scanner) or not, etc. Reloading the page/closing reopening the affected browser window doesn't help, i.e. the problem persists.

I recently found out, that this also applies to PDF files directly opened inside Firefox (which also seems to use pdf.js as a PDF viewer), that is, this is not related to a specific site like my DMS.

The problem always persists until I kill Firefox and start it over.

Pdf.js seems to use a canvas inside a div (see screenshots attached) to draw the visual PDF content and another div to make the text layer selectable/searchable etc. I don't know what's happening to canvases on a system suspend/resume cycle in Firefox on Linux, but I suspect that's where the problem originates from.

This problem already affected older versions of Firefox and pdf.js.

Please let me know, if you need further information from my side to investigate that issue.

Thanks a lot!

When I scroll up or down on the touchpad in firefox, it is like I scroll past a certain threshold, and it then sends a "scroll up" or "scroll down" command.

When I do this is Chromium, it's like I'm moving the website with my fingers. Similar to how it would be on a touch screen. In other browsers, the scrolling is not discrete, but continuous.

I love firefox, but this is driving me mad when I'm browsing. Is there any fix for this?

Addon windows do not retheme automatically when toggling light/dark mode

When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). This should also retheme addons opened in the sidebar (Tab Stash or Sidebery for instance), and it does so under certain conditions, namely if either a) no sidebar was opened when starting Firefox and the addon sidebar window is opened directly, or b) the sidebar was opened with start of Firefox. Unfortunately, no retheming of the addon window occurs when some other Firefox sidebar (such as bookmarks or history) was opened after Firefox start and before system theme switch. In that case, the addon window (which is opened as the system theme is switched) does not retheme. This can be mitigated by either restarting Firefox or by opening a Firefox sidebar such as bookmarks or history, and switching back to the addon window.

So to reproduce this behaviour:

  1. Open Firefox and some sidebar addon directly (such as Tab Stash in my case, with Ctrl-Alt-S)
  2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
  3. Observe that Firefox correctly redraws the addon window
  4. Open bookmarks (Ctrl-B) or history (Ctrl-H)
  5. Reopen the addon window
  6. Switch system theme globally again
  7. Observe that Firefox does not correctly redraw the addon window
  8. Open bookmarks (Ctrl-B) or history (Ctrl-H) again
  9. Reopen the addon window
  10. Observe that Firefox redrew the addon window

This has already been reported to the addon developer, who stated that it might be a bug in Firefox, since his addon only tells Firefox which colors to use in which mode.

System details:

  • OS Version: Linux 6.7.4-arch1-1
  • Browser Version: Firefox 122.0.1
  • Desktop environment: GNOME

Hi! I do not want more cookies than "necessary". So I reject, make settings etc. And I clean them automatically when closing Firefox, just in case. On some sites that I visit very often, this turns out very tedious and timeconsuming. How to allow only necessary cookies and not the rest? With Privacy & Security, Cookies and Site Data, Manage Exceptions, I can allow or block cookies from specific sites. What do I allow when I choose Allow? Only the ticked ones or all marketing and other stuff even when these are not preticked as default? Or will the choices made during this session be saved? In the case of my bank and a couple of others, I would like to save my choices to be able to enter it a little faster. But cleaning at closing Firefox also deletes that, I suppose? How to save my choices without saving all cookies?

Is there any way to see what kind of cookies have been saved? I can see the number of cookies for each site under Manage Data, but how to see the type of cookie?
