I am setting up a new desktop and want to copy my Firefox profile from one Linux desktop to another. In the past I have just used sync and then had to go thru the process of making all the config adjustments and tweaking other settings that are not part of sync. I just copied over my Thunderbird profile and it was a perfect copy and paste. Unfortunately I have tried twice with FF and its not working. Keep getting the message that the profile being copied in is from an older version. That's not true however the one being copied in is from 77.0.1 and the new desktop being pasted into is 71.0. Any idea what I am doing wrong that's an easy fix? Thanks.

On launching Firefox, none of the extensions work. uBlock Origin does nothing, LastPass prompts me to acknowledge their privacy policy then login, Firefox logs out of my user account, the containers tab does nothing (although this might be related to not being logged in). These are the only services I use. Everything works if I take the time to set them back up (except uBlock Origin).

Strangely enough, reddit.com will not load, and this is the only website I have had problems with. When prompted, the address bar ignores it, not even trying to load the site, completely blank page without an error.

Everything works perfectly fine (including uBlock Origin) in private browsing mode.

This started happening a few days ago. Since then I have done a clean install of windows (which was needed anyways) but to no avail. It is probably something stupid I managed to mess up in Firefox, although I would have no idea what that would be as I haven't changed anything advanced since the clean install.

I am completely dumb-founded. Any help would be appreciated.

I am running Firefox 76.0.1 on GalliumOS 3.1 on a Lenovo N21. For some reason, my add ons don't show up or work, even though they are installed. Firefox works great on my other two machines, and used to work great on this one. Thank you Jason Stone.

I frequently use a website that provides documents in PDF form. In the past when I selected a document to view it would open the PDF in the browser window.

I'm using Fedora 32 and I have the middle mouse button disabled in the gnome tweak tool. But for whatever reason, Firefox seems to ignore this. What I really want is for Firefox to stop closing tabs when I have the mouse cursor hovered over a tab and I touch the wrong part (the middle) of the touch pad. This is just a huge usability problem. I'm killing tabs all the time, sometimes with forms and email messages in them. Help?

Firefox used to allow a hack to add a custom search engine to the search engine list. This allowed users to make custom engines the DEFAULT search engine. (Engines can be added to Bookmarks but then they require a keyword to activate. Default engines do not require a keyword to activate).

The way to do it was: 1) place a folder called "searchplugins" with your custom .xml file describing your search engine (i.e.,, a URL with a %s added to it) inside your Home folder on a Linux OS.

2) open the Web Console

3) input: Services.search.addEngine("file:///home/user/searchplugins/custom-engine.xml", null, null, false);

4) now your custom search engine would appear in the search engine listing in Firefox and could be made default

On recent Firefoxes, this no longer works. When I inter the Sevices.search.addEngine part to the Web Console, I get this message: "ReferenceError: Services is not define"

I've been using Google Chrome because of stuff like this. Firefox just doesn't allow me to do what I want to do. But I appreciate Mozilla ideals and am trying to give Firefox another chance. But it is contingent on being able to make my custom search engine the default search engine.

Is there a fix for this error I'm encountering in the Web Console?

Hi,

See attached for details. One feature I'm trying to setup with FF is search engine query URL shortcuts. Basically, it allows the user to type a letter and it auto enables that URL. In this case, we're using Reddit. Basically, it allow us to type 'R' followed by a space which then auto populates the query URL. We can then type in our requested subreddits. However, I haven't been able to get this to work with FF. The search engine function add-on in firefox only enables a general search instead of subreddit specific. Would love to hear any feedback and/or solutions. Thanks in advance.

Hi everyone,

I am having trouble getting my custom new tab page to be focused when opened (instead of the address bar).

I am currently using the `autoconfig.js` + `mozilla.cfg` approach to overriding the `AboutNewTab.jsm` service with a custom local file. This is working great with the two files containing this code:

autoconfig.js: ``` pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); ```

mozilla.cfg: ``` // Custom firefox config

let { classes:Cc, interfaces:Ci, utils:Cu } = Components;

try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 let newTabURL = "file:///home/vallode/Documents/test/index.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e) { Cu.reportError(e); } ```

I have been attempting to use the `gBrowser` global to add an event listener to the new tab opening, but with no success. Could anyone point me in the right direction for something like this?

Is it possible to open Firefox from command line (or shortcut) without loading the URL or tab bars?

My current workaround is to load the URL and then click a bookmarklet which opens the tab in a popup window. Is there a way to open a link directly in a popup window?

I've scanned about:config to no avail, and it seems all the popup extensions just do what my bookmarklet does.

Ideally there would be a command line flag like --popup which does exactly that, but the closest thing I could find is --headless and --kiosk which don't work that way.

I also made a new profile named "popup" and intended to add extensions which hide the nav bar, but it looks like extensions aren't allowed to do that any more.

I'm on Windows 10 but still use Windows Live Mail. I used to be able to click the "Email Link" icon on my Firefox toolbar to automatically mail the current URL to someone using Live Mail. I can go into Options>Applications>mailto and link it to xlmail.exe but I can't add the argument "/mailurl:%" to the end of the command line so that it properly constructs an email message. This used to work - does anybody have a suggestion (other than finally abandoning Live Mail or Firefox)?

Thanks.

When I go to the about:config however it is not greyed out or locked in anyway. I was wondering if anyone could spot what I'm doing wrong.
