Firefox Support Forum

Hello, dear Firefox Help people!

I keep a lot of tabs open in my Firefox browser (121.0 64-bit for Windows 10). Starting just recently, if I closed Firefox by clicking on the "X" in the upper-right corner of the window, then the next time I start Firefox it opens without my tabs! (It never used to do this before...) It's very disconcerting, but I found that if it starts up without my tabs, Ctl+Shift+N will open Firefox in another window--with all my tabs! I can then close the original window (the one without my tabs), and go on using Firefox in my normal way.

If I have Firefox running with my tabs present, and I close Firefox by using Ctl+Shift+Q, the next time I re-open it, all the tabs are there. (That's also the case when I close Firefox using the three-line menu and "Exit".) But I used to be able to close Firefox by simply clicking on that "X" in the upper-right corner of the window, and next time I started Firefox it would open with all my tabs intact. I'd like it to work that way again... What must I do to get it to return to working that way?

(Please note that under Settings/General/Startup, I do have "Open previous windows and tabs" checked...)

Thank you for any help you can provide...!

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.

I've tried almost EVERYTHING offered to enable restore the "open previous windows and tabs" function ... to no avail. Very frustrating since I usually leave important tabs open for work. HELP!

Every time I open a new tab, another extra tab opens automatically with the following address: https://0.0.0.1/

showing this message: An error occurred during a connection to 0.0.0.1.

I already re-installed Firefox but this bug keems popping up.

BTW: I did not do a d*** thing. It just started yesterday and is extremely annoying!

My laptop had to do a restart and I have about 10 pinned tabs and I went to open firefox and they are all gone. I've tried to do the restore session but they aren't popping back up. How do I get them back???

My browser just updated to version 100.0 and now there's a big white block at the top that blocks access to tabs and the Minimize/Maximize/Close buttons at the top.

I found a few other articles going back to 2015 with this same issue and the only solution that helped a tiny bit was checking or unchecking the Title Bar box. Unchecking it helps a little bit as you can see in the attached screenshot.

The top of the image is with the Title Bar box checked, the bottom of the image is with that box unchecked.

Any idea how to resolve this?

I find this does not happen when I opened Mozilla and searched for an answer, but if I am in almost any other site, and click a link, it oens in a new window and is so narrow, it is unusable until I stretch i. This is a pain, and never happened ubtil about 1-2 months ago after an update.

Please let m know if anyone has a solution to this irritating challenge.

When I have a website open and want to open a new one from the bookmark bar it opens it in the same tab, thus losing the first website. How do I stop this happening? I want to open several websites from bookmarks and have them all open at the same time. Thanks.

Hi there,

"When you open a link, image or media in a new tab, switch to it immediately" is happening - even though the box is unchecked. Only in favorites bar, not in web page or Firefox homepage Shortcuts (1 row or 2 rows) or Recent activity.

It's very irritating, so i hope there is a solution...?

I use google meet a lot. I need to screen my screen very often. i have used other web browsers which let to share a singe tab in the meet, but in firefox, can only get the option for either a window or an entire screen which is very inconvenient. I hope to hear from you soon because i use firefox and its be a shame for me to switch to other web browsers completely for this issue. My email is vijay.rh@gmail.com

I have lost my tabs after accidentally clicking top right hand cross and now can't all my 30 tabs back, very frustrating! This the one that keeps coming back which is not the page I want.

Why is there now no option to close present tab only when clicking on X. The old (default) warning was excellent. With no warning, clicking the X kills Firefox - and all open tabs. This has lost me hours of work already. i certainly don't want to go down the route of restoring all tabs first. I can't rely on it, for instance, holding all comments made on a form. And for that matter, I wouldn't want that to reinstate a login.

Please can we return to the warning with 2 options Close all tabs and Close current tab only.

Sometimes, I'll click a new tab, and "something" happens. It's like it tries to create a new tab, yet it's just a half-formed nothing that you can't interact with. And when this happens, Firefox is destined to eventually crash / become unresponsive. I literally have to reboot to get Firefox working again. I haven't tried logging out. That would probably work, too.

This also happens when moving new tabs, but I've only notice that happen on tabs with Youtube.com open.

Olá. Quando eu clico em alguns arquivos eles estão abrindo na mesma aba. Isso acontece principalmente no WhatsApp. Eu gostaria que os documentos fossem abertos em nova aba.

This has happened twice now - I've had a main window open with 100+ tabs and a second window open with only one tab. All settings are as described to save history, etc. After closing Firefox and later restarting, only the window with a single tab is restored. I've saved the session backup files in another location and manual copied and renamed them into the main profile folder but in each attempt, only the single tab window was restored, which is obviously not what I want. I know the 100+ tabs are in the file because of the filesize and because I've used https://www.jeffersonscher.com/ffu/scrounger.html to scrounge the URLs from the backup file. But the point is that Firefox is NOT extracting the data from this file and restoring the other window, which makes me suspect there is a bug or problem with session restore when more than one window is open at the time of shutdown.

Thanks for any suggestions. Bob

I went to settings and set firefox to open links in a NEW TAB instead of a new window, but it still opens links in a new window. I did a search on google and when I click on the link for the website to see the information it is still opening in a new window. How can I fix this so I don't have a lot of new windows. It's irritating to have to close all those stinking windows just to get back to my original window. I just want the links I click on to open in a new tab.
