How to stop Firefox from going to an already open tab when trying to open the same site again ?

yes i want 10 tabs open on the same site, stop switching to one open tab. i discovered i hold shift/alt ti prevent this, there must be an option to disable it altogether, how?

When using private browsing window, bookmarks toolbar keeps disappearing every time I open a new tab or anything else. My setting for show bookmarks is "always show" and it works normally in a regular window. It also used to work normally in private browsing until a few days ago. Clicking "show bookmarks toolbar" works until I open any of the bookmarks, then the toolbar disappears again. How do I make the toolbar permanently visible in a private browsing window?

After installing Update 123.0.1, History and Bookmarks no longer show up in the search bar even though they're still checked in my Search settings. What could be causing this? Thanks!

Hi,

I'm trying to remove the bar at the top of firefox browser with tabs in them. I read another article (https://support.mozilla.org/es/questions/1417387#answer-1588947) under spain link, i think, and the solution said to write "TabsToolbar-customization-target { visibility: collapse !important; }" somewhere. Where do I go to write that?

I tried the console by pressing f12, but that doesn't seem like that's it. In that article it also mentions to go to about:config and change the status of "browser.tabs.drawInTitlebar" to false, or delete it, but didn't work either.

Firefox just updated. Now my Bookmarks Toolbar Menu is decimated and replaced by "Most Visited". How do I get back all the bookmarks I have saved over many years. I want them even though I don't visit them often.

Hello,

I install language pack from https://addons.mozilla.org/en-US/firefox/language-tools/ https://addons.mozilla.org/en-US/firefox/addon/russian-ru-language-pack/

But there is still no sub-menu item in the menu

My V123 for W11 doesn't show the vertical scroll bar unless the cursor is there. There's no "always show scroll bar" option in under general/browsing.

Is this a glitch? Can it be fixed?

Hi, I just downloaded a Firefox browser, but on the left of bookmarks toolbar there is an "Import bookmarks" that I can't get rid of. I've seen a couple other things that say it's like removing a bookmark, but that doesn't work for me. I've looked and can't find how to remove it. Any suggestions are appreciated!

I am having a very frustrating problem that is driving me huts.

Just the other day I was commenting in a text box like this one and I hit caps lock on my keyboard and a little grey box I had never seen before appeared with a locked lock. Then when I hit caps locks again on my keyboard an unlocked locked appeared in the little grey box. But it stays in cap locks and no matter what I do it won't go back to lower case. And when I say nothing shuts it off I mean its doing that on every site I try to comment on. Shutting down the browser does not help. And the only way I can get caps lock off is to actually shut down my whole computer and basically start all over.

You community volunteers are the best and quickest help I can get so I went straight to you for help.

I want to uninstall and maybe re-install some add-ons. But when I goto the add-on page. It just appears blank. So are some other pages in the support/ help sections. Another most notably, is (via menu) help -> more troubleshooting information. It just sends me to a blank page! See the uploaded images for the pages I get send to.

Help please with changing my add-ons

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.

I've read all the suggestions but can't get Firefox Sync to transfer the open tabs from my old PC to my new one. I'm signed in on both to the same account, both are on my LAN with a wired ethernet connection, and I've checked every box in the "what to sync" field. When I click "Sync Now" the icon spins for a few seconds like it's doing something but the tabs from the old machine do not appear on the new one as I expected them to. Nor can I get them by closing and doing a Restore Session.

This seems pretty straightforward and how most users would expect it to work - am I missing something? If not, why isn't it working?

A couple of weeks ago I migrated from Edge to Firefox. I exported and imported my bookmarks. All was good. Suddenly this morning, my bookmarks are inoperative. The folder structure is there, containing entries that appear to be my bookmarks. If I left-click on one, nothing happens. If I right-click on one and choose Edit Bookmark, the fields in the dialogue are all empty.

Hi!

For a few weeks now I've had the problem that my Mozilla Firefox browser keeps crashing or hanging (the image goes black, needs to be updated or then crashes completely). This happens regardless of the website you open (e.g. google maps, mymaps, canva, instagram, google sheets, google drive, amazon, etc.).

Here are some of today's about:crashes IDs: bp-eee64bce-504e-4b09-bd26-d74a40240303 bp-aebd34b7-cdc1-49bd-9090-ca6b00240303 bp-b0970e4e-7f08-4672-9a4d-ca16f0240303 bp-14ded6d2-b81a-4d76-b79a-26b000240303 bp-d751619a-ce2f-4ffa-817d-0557c0240303 bp-27d145c4-4ef7-481d-9ffa-12e570240303

I already checked my RAM with memtest86. There were no errors. My tribers are updatet and I use Avast Antivirus & Cleanup Premium.

Do you have any idea, why this happens?

Kind regars, Minnie

Ubuntu 22.04.3 LTS Firefox 123.0 (64-bit)

The browser deletes cookies when closed. Every time I log in, I need to re-enter passwords (they are saved) on all sites, this is certainly tiring. I read about a similar problem from other users, they had the “Delete cookies and site data when Firefox is closed” setting enabled, but I didn’t.
