Firefox Support Forum

When opening a new website when a window is already opened I want Mozilla to add a tab and not create an entirely new window. How do I change this feature which presumably is in "settings".

All of a sudden, I can no longer open new tabs in Firefox just by clicking the top bar (sorry, don't know how to describe this: the space that sits just below the line with 'File', 'Edit', 'View', 'History', etc. (Menu bar?) Formerly, when I had a tab open I used to be able just to click that line and a new tab would open. To open a new tab now I have to look to the right of the screen, and press the '+' button (Open a new tab Control+ 1) that appears in that same area just below the that is there. Not nearly as convenient. Please tell me how to fix this as simply as possible (I am not very computer literate). I have done nothing to change anything in the Firefox settings, so don't know why this happened all of a sudden. Very frustrating. My bookmarks all disappeared too, by the way, thoughI figured out how to resstore them to top of screen. I am using Windows 10 Thanks in advance, A frustrated Cynthia

This is happening near a year and I can't find a way to consistently replicate this issue but;

While Private Mode is open, if I open the Normal Mode, visit some sites then close it, when I reopen the Normal Mode it is restoring the last session.

This wasn't happening when the Private Mode was separated, like umm, it wasn't have it's own icon at the Task Bar.

So far I tried setting these values to false in about:config browser.sessionstore.resume_from_crash toolkit.winRegisterApplicationRestart

but it doesn't help with this problem. It only works if the Firefox actually crashes or closed abruptly like powering off the PC. But doesn't stop it's restoring when done this way.

My Firefox window with 15+ tabs just crashed. I watched a YouTube video and the solution offered doesn't work. How can I restore them? And does Firefox really not have a way to speak to a human being??

Just lost it.

'why are there false tabs open when i restore the session? i know wich ones were open yesterday and today it click on firefox and all tabs are wrong. tabs i didnt use fore months are opend wtf can i do????

Please add support for progressive web apps to firefox, it is the only reason why I have stopped using firefox in preference of chrome. Without this feature, we can't use websites in split screen without the search bar area eating into the web page.

Help please.

I had to factory reset my laptop (or rather, an IT support person took over my machine and reset it before I could back up things properly!). I was not able to restore my previously opened tabs (there were a lot, like >100). It appears that all of those tabs still are showing on my mobile version of firefox as 'synced tabs'. Is there a way to pull that sync information from my phone to my laptop? If I press on "synchronise tabs" will the phone receive my laptops current tabs (not what i want), or will it update the laptop (what i do want)?

Thank you.

Often times when I open a new tab, I get a dot that goes back and forth and will not open the tab. This seems to happen if I don't use Firefox for a few minutes. It's like its trying to open but can't.

I recently downloaded Tree Style Tab. I still see the horizontal tab bar. I would like to hide it. However, I have tried just about every answer I could find on Mozilla, Google, Reddit, and any other websites that offered solutions. Nothing has worked since the last update. This includes the "type in about:config, toggle to true, open profile folder, create userChrome.css file, copy and paste xyz code, save, and restart Firefox" route.

Any help would be greatly appreciated!

Is it normal that we should install an extension to be able to open a specific url when opening a tab. That don't work because of x-frame options.

We already can add a custom url for new windows, so why not for tabs.

Firefox is taking weird directions.

FF doesn't reliably open my last session. It used to but for nearly 18 months now it has become hit and miss. I have FF docked on my taskbar (Win 7 sp1) when I click it some times it opens all my tabs (I have it set to do that) but more frequently it doesn't and just opens one tab. Usually I catch it and in history select the tab showing many other tabs and I get it all back, but this doesn't always work like today, no option to do that because there's nothing there. When is it likely to be fixed, I've been complaining about this for months. I've even suggested FF collects a stack of last sessions (say 20) each time a session is closed and have a fixed entry for that in the menu, but nothing seems to change. I'm heartily sick of it, it's such a basic requirement of any browser and yet with FF it's just a pain in the neck.

How can I import or to which folder do I import bookmarks so they show up in the shortcut rows in a new tab? I'm trying to get away from Opera but I love the shortcuts displayed on a new tab. I tried copying all the appropriate bookmarks to the bookmarks menu folder and why they are in the folder they dont display in the shortcuts.

The imagine shows where I want to import to.

I did a 'refresh' of my browser, thinking that basic user information would be saved. But I lost all my tabs in OneTab (extension). Is it possible to recover them?
