When I download a file (eg. a debian binary package) and click to open it from Firefox' download tab, it doesn't use the system default application (here, Ark instead of QApt)

I'm wondering how to configure a default zoom level for all users.

I want

about:preferences -> Default zoom

to have a default value of 133% instead of 100%.

So far I'm using the files

firefox/distribution/distribution.ini

and

firefox/browser/defaults/preferences/all-XXX.js

for configuration, but I don't know which keyword to use. I compared the content-prefs.sqlite file between to test profiles, one having 100% default zoom, the other having 133% default zoom.

The database says there is a setting "browser.content.full-zoom", but I can't configure this with the *.ini or *.js file, or can I?

I also read this:

https://developer.mozilla.org/en-US/docs/Mozilla/Preferences/A_brief_guide_to_Mozilla_preferences

but it didn't help.

Have some trouble with FF browser on Linux (kubuntu 20.04). Sometimes, when i open browser (after power off, or restart my computer), found what i'm out from my account, and need to input password again and again. I have no idea that happend.

P.S. my English is no good

Hi,

I am trying to configure PKI based authentication and encryption system in my organization using Hardware token. I was able to install my hardware token feitan ePass2003 Auto in privacy->security device. I am able to see my certificates under view certificate after entering my password for private key. After research on internet, came to know that Applet based client authentication is obsolete and hence i have configure my token in Firefox. The next step i.e Authentication page is where i have got stuck up. Can any one please give details guide on how to use cryptoken operation(challenge & signing) and access to token in JavaScript at client side login page. I could not get hold of any library of java script for access to token through Firefox. Any guidance is highly appreciated.

Thanks

All I'd like to know is how to completely disable the ability of tabs crashing for any reason at all, permanently. I'd very seriously would rather the computer freeze or risk hardware damage, whatever pref(s) listed and unlisted I need to enable or disable I can put in lock file or anything. -Thanks!

I don't really know if this is a bug, or a feature of Firefox's JavaScript core engine. Say I have an array:

var array = [];

I set the length of the array to a very large number:

array.length = 155555555;

This now turns the variable array into an array with 155555555 blank slots. If I then do:

array[502039410402] = 5; // Notice that 502039410402 > the previously set 155555555 for length

array.length remains at 155555555, but the actual array is appended with a sudden index 502039410402 (i.e., index 155555553, 155555554, and then suddenly index 502039410402; see screenshot), with that element containing 5. Is this a bug, or an intended feature?

I would appreciate it if anyone could let me know.

Thanks!

Hello.

I use 76.0.1 (64-bit) on Xubuntu 20.04 and same thing happens on every computer. After clean system shutdown or restart, Firefox keeps restoring tabs I used. This never happens if I close Firefox first. Also this never happens when I close and reopen firefox in the same session. I tried everything: - obvious "Restore previous session" restore in options - about:config turning various options: browser.sessionstore.resume_from_crash browser.sessionstore.restore_tabs_lazily browser.sessionstore.resuming_after_os_restart browser.sessionstore.max_tabs_undo browser.sessionstore.restore_on_demand privacy.clearOnShutdown.sessions - i even created "user.json" with restore line as someone suggested None of these measures helped. I thought that It may be connected to XFCE session store somehow, so I went through disabling that too - no change. No other program happens to do the same. After reboot, when someone starts Firefox, all my tabs from previous session are reopened instantly. This happens on my both Xubuntu workstations, but never happens on my Windows computers. Please help.

Recently i got a problem related to push notifications on Firefox, I've already subscribed (or allowed) to notification permission on some websites like Twitter, Gmail but I don't receive any notification when I closed their tabs . It's working fine if the tab of particular website is loaded on Firefox but once I closed it I don't get any notification especially from those websites on which I allowed the notification permission.

Some people suggested me to use chromium or other browsers to get this behavior but I don't want to replace Firefox with any other browser because their dev tools are better than what others are suggesting to me.

Firefox version: 76.0.1 OS: Manjaro with I3gaps window manager Script (or app) for display the notification : Dunst

I am using Firefox on a Fedora 32 linux system. I have two "printers" defined, one configured for duplex printing, the other not. I would like Firefox to enable or disable duplex printing according to which printer I use and not have to change the setting in Firefox every time I want to print with a different setting than the last time I printed. Is there any way to do this?

From a non-programmer who used Chrome a lot until recently:

If I hit Cntrl-H like I would in Chrome, I get a frustratingly limited view. Why does it not show timestamps? So I spend time searching and find out about the Library window, and Control+Shift+H. Okay, so that's at least making it possible to see timestamps. Typing this right now, I don't remember if I had to manually add a column to see timestamps, but if I did Jesus Christ. I nearly installed some other software (MZHistoryView) before finding out about Control+Shift+H, just to see timestamps.

Also, every time I press the awkward Control+Shift+H hotkey, it resets the view to "Today". I don't know why it wouldn't default to "Just keep scrolling for as many days as you want". If I search for a specific site immediately after opening the window, then it includes entries for more days than just today. But before searching, it cuts off my view to just today. What's the point of that? Who would want such a restriction as the default view?

Hello everyone,

Is it possible to control Firefox 76 on Linux from D-bus ? I listed all available services with "qdbus" utility, but there is nothing like firefox/mozilla. Also, I browsed source code, and I saw D-bus support seems to be there. Thank you

I have been trying to order a set of your devices. An hour of trying has brought no success. Tell me what I am doing wrong. Can I order then by telephone from Canada? THANK YOU.

Guten Morgen,

meine Passwörter sind plötzlich weg, ich möchte keinen Brauser der die Passwörter vergisst. Warum passiert dies immer wieder?  

Es sollte eine sehr einfache Rückhohkung geben und nicht so ein umständliches Suchen nach den vorhandenen Passwörtern und der Rückholung!!!

Ich habe ein umfangreiche Internetseite von über 30 Domain etc. wie soll ich da die ganzen

Passwörter merken!!!

Es ist ein Unding, wenn Firefox plötzlich die Passwörter nicht anzeigt, so ist dies eine Stundenlange Arbeit!!!

Ich bin sehr unzufrieden mit Firefox

I am using Firefox 76 on Ubuntu 18.04 LTS and sometimes after I do a system restart or shutdown, the previous session I had disappears . I am using the Tab Group Manager add-on and have the restore previous session option enabled, yet it still happens. Any ideas on how to solve this or if it will be patched?

Thanks,

Milton
