Dear Mozilla Support, [please forgive my poor English - FRENCH is my mother tongue]

CONTEXT - I use a Linux (Peppermint) Live DVD to surf the Web, always on the same laptop. I do NOT use any hard disk inside that laptop, just the Live DVD spinned by a DVD player. Only the RAM stores data => fresh new distro for every session - years ago, I created a Firefox account, and the Sync worked perfectly, and allowed me to back up my Bookmarks AND my Opened Tabs (they are stored in Mozzila's cloud, and after each sign in and a sync, they reappear in the left panel). Regarding the Synced Tabs, the left panel used to store all the previous Live DVD sessions (generally with the device's name: peppermint's Linux... (IIRC). - i do NOT use several devices, and do NOT wish to sync date acreoss them. I use Sync to get my Bookmarks and Opened Tabs synced across successive Firefox sessions, day after day. I worked perfectly well.

PROBLEM Since a few weeks, I noted that despite login and sync, on the left panel - Synced Tabs are now empty: no tabs synced at all => so I cannot seamlessly find back my opened tabs from one session to another (if I switch off my laptop, then later restart a new Live DVD session) - see screenshot = https://imgur.com/LO6jWLYl.png - Bookmarks are nevertheless still perfectly synced (see screenshot = https://i.imgur.com/Td0nbY2.png)


Many thanks for you help. Kind regards from Europe.

As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();


However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."


If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();


I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

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!

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?

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.

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

Hello,

Like I suppose any user of older systems (Macs...) that cannot be updated to a newer OS version and thus locked-in to an older Firefox browser I received an email today:

"Don’t stop the sync. Upgrade your Firefox before March 31st."

Why, why, why??

Why would Mozilla take away this last little bit of usefulness after already having abandoned all updates to the browser itself? Why actively "fix" something that ain't broke in a why that does actually break it?

And don't give me the sacrosanctuous security argument please ;) - I never synced sensitive information, not even my browsing history. If security *is* the reason it should be hardly more difficult to disable/disallow just the syncing of that information at the server end. We're clearly speaking at a change on that end anyway, otherwise everyone NOT running the very latest version would be urged to update, not just users of v78 and older.

Anyway, I'm sadly aware of the fact this little rant or even a concerted action isn't likely to change anything, so what options are there? Any suggestions for browser extensions that provide syncing of bookmarks and maybe open tabs or even browser preferences?

Thanks!

PS: I'm posting this from another older system currently still running a Ubuntu 14.04 version that is in fact hardly younger than my Mac's OS but still enjoys Firefox updates...

I have enabled privacy.resistFingerprinting in Firefox. I have also set my default zoom level to 133%

When I open a website (e.g. https://github.com/), it is zoomed to 133% as expected. If I then navigate to a page on that website (e.g. https://github.com/pricing) using the menu at the top of the page, then the new page is still zoomed to 133%. So far, so good.

However, on the new page (https://github.com/pricing) if I increase the zoom over 133%, then navigate back to the original page (https://github.com/) using the menu at the top of the page, then my zoom level is reset to 100%.

Is this expected behaviour? I would have thought that the zoom level would be reset to 133%, not 100%.
