whenever I try to use a theme that defaulted to dark mode in the previous update, it defaults to light mode instead. for some websites this means that it displays in bright white. i need dark mode. even when i set the toolbar colour (which previously controlled dark/light in Firefox Colour) to black it's on light mode. how do I get dark mode back, i hate this. this theme (picture attached) used to be dark mode but now it defaults to light. how do i get dark mode back.

I recently obtained a 17" laptop, and have a large number of bookmarks. I have the bookmarks toolbar open, and would like to force the bookmark sub lists to open to the left of the primary list whenever possible. Is there a setting that would allow me to do this? Thanks in advance.

I know Firefox recently changed some settings regarding automatic downloading of files, but I need to know how to stop Firefox from automatically downloading .pdf files that I view. Sometimes I just want to view a pdf without downloading the file. Firefox keeps automatically downloading the file, then after viewing it, I have to manually delete. I don't to do this! I just want to view the file and if I want to keep it, I'll save a copy. This is extremely annoying! Can I change the settings so that the file won't automatically save to my computer? Thanks

Hi. I'm using firefox for last 7 years or so. I am here to request for a feature tobe added to android version of firefox. The MOUSE/TRACKPAD feature. I tried to navigate through a particular website and i couldnt navigate further . Because the confirmation dialogie box won't close on touch. So keep searching and i found this feature in PIDGIN web browser, which is about to retire soon. It allows a MOUSE POINTER on screen . It helped to close the dialogue box. Adding this feature will help me use a single browser instead of looking for alternatives. I will include the screenshot of the same.. please consider my humble request

Thanks team Mozilla

I have the Download setting set to "Always ask you where to save files" and PDF handling set to to "Open in Firefox" if I now click on the download button in the opened PDF it automatically saves to the Download folder without asking, which is never what I want. If I set PDF handling to always ask, and open in Firefox from the dialog and press on the save button then I get asked where to save. This seems like a bug to me, as it is very surprising behaviour. Is there some way to always open the PDF in firefox but get asked where to save the pdf when pressing the download button in the PDF viewer?

Hi,. I am trying to enter a sweepstakes on one of my websites, HGTV. They have a new dream home giveaway which I've never had an issue with. How can I clear whatever is blocking me from entering. It allows me to put all my info in bur when I hit enter, it clears out my info and doesn't enter me I to sweepstakes. I just need to clear whatever is blocking me just from this one website and cannot get it right. I am sure there is an easy solution but I don't know what that solution is. Thank you mych!

Running Firefox 100.0 on Linux Mint 20.3 Mate 1.26 I've noticed that websites like my bank use a "sub window" that slides in from the right to display the running balances. Prior to version 100, this worked perfectly with dual scroll bars, one for the main window and one for the "sub" window. Now, with version 100, the "sub" window has no scroll bar. I can control the window by using the keyboard up/down arrows, but the scroll bar for the "sub" window is non existent. You cannot have access to my bank account, but you can duplicate the problem with Google. Simply search for say, a celebrity, click on one of the displayed images, and the window that displays on the right used to have it's own scroll bar, beside the bar that controlled the main window. Sub window scroll bar is now gone. It seems you folks violated one of the Cardinal Sins of Programming: IF IT AIN'T BROKE, DON'T FIX IT. Scroll bars worked great before, Not sure whose idea it was to "improve" them. Rolling a Firefox update backwards is a logistical nightmare. Is there a possibility of a fix coming out soon or are we to live with this as a "feature"??? Thanks for your time.

In a previous thread 5 years ago, it has been asked how the e-mail filters can be backed-up. Back then, the suggestion was to locate the msgFilterRules.dat in the profile folder.

I just created a new user profile in Thunderbird 91.9.0 and I created some new filters, but the file msgFilterRules.dat hasn't appeared in the profile directory. Has the file been changed? Any tips on how to back-up the filters? Using Ubuntu 20.04.

SOLVED: one has to do the following steps:

1. Go to Help>More troubleshooting information>Profile Directory > Open directory 2. Right click, open in Terminal 3. type the command "find . -name 'msgFilterRules.dat'

this will list all the filters, dependent on different e-mail servers

Hi All- I am in charge of deploying Firefox ESR to my company and trying to get it to silently auto update on it's on with user interaction. We have policies in place (GPO) that prevent it at this point. I need some guidance on whether I should use just GPOs to manage this or should I go the route of the .cfg file? If someone has a step by step on how to best achieve this I would appreciate it. I am currently using the .msi installer.

Here is settings in an old .cfg file that I am testing with:

lockPref("app.update.mode", 1); lockPref("app.update.service.enabled", true); lockPref("extensions.update.enabled", false); lockPref("extensions.update.autoUpdateEnabled", false);

// Set default homepage - users can change // Requires a complex preference defaultPref("browser.startup.homepage","data:text/plain,browser.startup.homepage=http://workday");

// Don't ask to install the Flash plugin lockPref("plugins.notifyMissingFlash", false);

// Disable Search Engine automatic updates lockPref("browser.search.update", false);

//Disable telemetry lockPref("toolkit.telemetry.prompted", 2); lockPref("toolkit.telemetry.rejected", true); lockPref("toolkit.telemetry.enabled", false);

// Disable health reporter lockPref("datareporting.healthreport.service.enabled", false); lockPref("datareporting.healthreport.logging.consoleEnabled", false); lockPref("datareporting.healthreport.uploadEnabled", false);

// Disable all data upload (Telemetry and FHR) lockPref("datareporting.policy.dataSubmissionEnabled", false);

// Disable crash reporter lockPref("toolkit.crashreporter.enabled", false); Components.classes["@mozilla.org/toolkit/crash-reporter;1"].getService(Components.interfaces.nsICrashReporter).submitReports = false;

// Don't show WhatsNew on first run after every update pref("browser.startup.homepage_override.mstone","ignore");

// Don't show 'know your rights' on first run pref("browser.rights.3.shown", true);
