I want to use a command option to open a new blank tab in a specified portable instance of Firefox using a specified profile.

I constructed my command like this:

"Path-to-Firefox-executable" -profile "Path-to-Profile" -new-tab "about:blank"

It partially works (it opens the correct instance of Firefox and uses the correct specified profile) however it always opens about:newtab instead of about:blank.

Seeing as I am specifying the exact page to open, any New Tab settings in the browser should not matter, and I should just get the page that has been specified in the command.

If I manually type about:blank into the url bar, then a blank page opens as expected, so the url is correct, it just won't work for me as part of the above command line.

Does anybody else have this issue? How can I get this to work correctly?

Just a couple of quick questions for CSS coding as of Firefox 115:

What CSS code refers to the shield, padlock, permissions, or all other toolbar buttons in the address bar?

When using control to select multiple tabs, what code refers to the outline and text color of the tabs?

Images attached for reference.

Thanks in advance!

I closed all my tabs and reopened the browser bc I was getting lag on sites like X.com when typing my messages. Immediately after opening Firefox again, my homepage, MSN.com was loaded. I tried to click on the arrow to scroll through the different headline stories and nothing happened. I used Chrome & Opera to load the same page and they work fine. This seems like a Firefox thing. I have no extensions or permissions that deny me the right to click on anything. What is the problem?

Hi there,

In the search settings, I have set DuckDuckGo as my default search engine and removed all other engines from the list of options. However, I often notice that Google (which I have removed from the options) has replaced DuckDuckGo as my default search engine and has again been added as an optional search engine, without me knowing. Why is this happening? Is it possible to stop it happening, and if so, how can I stop it happening?

Cheers Paul

If I am on a web site and click a link to another page on the same website Firefox opens a new tab rather than displaying it in the existing tab. How do I get Firefox to NOT do this?

I use Mozilla as my browser on Windows 7. When I click on Mozilla I get an Error page which reads, " Server Error in "/" Application. Runtime Error. Not sure how to fix this. Can you help. Thank-you

I just got a new computer, and I'm trying to copy-and-paste a profile over from the old computer to the new one, but this doesn't seem to be working. Firstly, when I click on the Firefox icon on my new computer (Windows 11), the profile manager doesn't start up, so I can't choose the old profile. I've tried copying over all of the old files into the new profile folder, and that didn't work, either. What's going on?

When a new bookmark is created it goes to the end of the bookmark listing in the left panel. How can I force Firefox to automatically put each newly created bookmark in the correct alphabetic position in the left panel Bookmarks panel? I DO NOT want to alphabetize the entire panel, I just want each newly created bookmark to go where is alphabetically belongs. I do not use folders so have one long list for bookmarks menu. thank Bob

Firefox detected a potential security threat and did not continue to noodlemagazine.com because this website requires a secure connection

On homesnap web site I get a pop-up window for homes.com. I can't get back to homesnap & I can't get rid of the window to redirect to homes.com. What can I do? Thanks

I've used Firefox for years and I like it!! I'm just wondering if there is anything Mozilla can do to counter the apparent collusion between YT and MS to coerce people into using Chrome, by means of YT degrading their videos when playing on Firefox?!

To log into my mortgage lender's site I have to enter my email address. Beside this field is the Facebook container symbol; mousing over it warns me that if I enter my email here, Facebook can track me. Mortgage Lender used to allow me to log in with a user name, but now requires my email address, which apparently gives Facebook access to track me. Tried speaking to the lender about this, but they simply assert there are no Facebook trackers on their site. So, any workaround for this besides just doing all my business with them by phone from now on?

At some point in the winter of '21 I created a folder of bookmarks that was saved in the 'bookmarks menu'. At a later date, hard to say when but probably '22 or early '23 I deleted these bookmarks. I now desperately need to recover them.

The oldest auto-backup from 'Manage Bookmarks' -> 'Import and Backup' -> Restore is dated mid '23 and does not contain the deleted bookmarks.

Is there any hope of recovering them? For example via the Recycle Bin or by using a data recovery tool? Or will they have been overwritten?
