Firefox 技術支援討論區

Hi, Imaging that, firefox is open, I clicked on a button that opening new window, how I can merge this 2 window in 1, in fact I wanna have that new window as a tab.

Google Chrome have this already.

Thanks !

It's so frustrating that the keyboard shortcut for closing tabs is right beside the one to quit Firefox. I've lost countless hours because of this, and it's so easy to accidentally do. Is there a way to keep this from happening? A simple "Are you sure" confirmation dialog would be great, or I really like the Chrome "hold command-Q" to exit feature. This seemingly simple function is proving extremely difficult to accomplish.

Yes, I'm aware of session restore, but (1) It does not preserve my window arrangement. I use multiple desktops for various tasks, and they each have related browser windows. (2) I need to see webpages exactly as they were when I opened them. Sessions expire, dynamic pages are refreshed, content is removed etc. That is all lost.

I do not want to disable session restore completely. It can still be useful. But, I do not want to trigger session restore automatically every time. Manual activation is ideal.

regarding: "browser.tabs.warnOnClose" I do not want a warning for closing multiple tabs. I often have many windows open and that warning gets annoying. It also doesn't prevent me from accidentally quitting when I only have one tab open.

I tried setting browser.warnOnQuit to true, but it's ignored.

I simply want a confirmation when I use the keyboard shortcut to QUIT. That's it. No side effects. Can Firefox do this?

I searched this forum but couldn't find an answer. I have "restore last session" turned on, but I'd like Firefox wouldn't reopen my last visited site after I close the browser by closing the last tab. In other words: if I close the browser by a regular means (by clicking the rightmost upper X, or by right-clicking the taskbar and choosing close window) it goes to the last viewed site when I reopen the browser – and that's ok – but when I close the last tab and the browser closes, I don't want to see this site again when I reopen Firefox. Is there a way to achieve this? By the way, this is the standard behavior in Google Chrome.

I use Send Tab to Device all the time. To my phone, my tablet, my work & home laptops. Except recently, the tab I send won't show up on my phone. Notifications are enabled. I can send from my phone to my work laptop. I can send from my work to home laptop. But to the phone, it says sent, and nothing ever arrives. Everything is synced. What else can I do?

Ever since IE changed to tabs on top firefox coders followed like mindless automatons without any regard to/for Mozilla community and users. We are sick and tired of being ignored. We want/need tabs bellow address bar. Now, tell us how to simply get tabs below address bar or tell the coders to provide us with the option. And, we don’t care about any excuses as previously provided or outright ignored by them.

Before shutting down Firefox I deleted history/cache/passwords etc from the past day

I do this all the time but since I had restore previous tabs selected they always get restored when I start up again

However this time they weren't restored when I restarted

Without closing Firefox I navigated to the sessionstore-backups folder to see what was there but the files were only 2KB - much too small for the number of tabs.

So I installed ShadowExplorer & Shadowcopyview to see if I could recover older versions I was able to locate jsonlz4 files from a few days ago that were around 11000KB in size so I assumed they would have most of my tabs

However when trying to use the files nothing happens - I tried 2 different steps that I read here had worked for others

1 - Renaming previous.jsonlz4 to sessionstore.jsonlz4 , moving to the profile folder (deleting the old one first) and restarting FF

2 - Deleting sessionstore.jsonlz4 and copying the recovered previous.jsonlz4 / recovery.baklz4 /recovery.jsonlz4 / upgrade.jsonlz4-20201014125134 files to the sessionstore-backups folder and restarting FF

I also repeated the steps after creating a separate profile

None of these worked so I tried examining the jsonlz4 files using https://www.jeffersonscher.com/res/scrounger.html but I got an error message 'Session history file contents could not be read?'

Now I've previously used recovered Jsonlz4 files to restore tabs with no issues but this time they won't work

I read here https://support.mozilla.org/bm/questions/1189759 that updates may cause compatibility issues and the upgrade.jsonlz4-20201014125134 file indicates they was a recent update

The recovered file sizes indicate they contain data so I want to know how I can recover it - if not through FF then through some other software

firefox tab name edit: can a user name tab at will ?

right now it has LOGO and "Home" but i want it to read something like OSC-US Office of Special Counsel-Independent Agency-Home because i just do.

i have three other bookmarks for OSC: i can edit the bookmark name from "properties" but have never known whether i can also edit the name shown on a tab.

LOGO Home isn't too helpful to me. but even just knowing that i CAN'T edit tab names will be helpful to know, so i can stop thinking about it and get some sleep after another bag of chocolate-chip cookies. being an american right now is plenty stressful.

who named them "cookies" anyhow?-is it bc they kind of leave crumbs? did i win?

thank you for helping. i do appreciate it.

I got an error on one of my open or pinned tabs (do not recall which it was). I do not recall what the error was and did not screenshot it because I was sure that closing Firefox and restarting it would fix the issue. I did just that, closed Firefox and reopened it to find that ALL of my pinned and open tabs were GONE. This also happens if another instance of Firefox is opened and I close my main one first by accident and then close the other Firefox instance - ALL TABS LOST.

This is what I have done: • I started to restore the pinned tabs as I could remember what they were but I was not able to remember the open tabs that were not pinned • I searched for lost tabs on the web and on the Mozilla support site but was not able to find any useful help - most of it seems outdated or no long compatible with my version of Firefox. • I looked for the sessionrestore files on my local PC but could not find them - this must have changed in some version of Firefox between version 42 and version 82 that I have. • I looked in the AddOn store to find something that would help restore and prevent this issue - but found nothing. A very old post, from 2012, indicated one that did this but it is no longer available. • All of the Options in Firefox to restore previous session, reopen previous tabs and all that were blank.

This is VERY frustrating in that it results in lots of down time to recreate what was open and is equivalent to working on a document for days or weeks only to find out that the Microsoft file got corrupt or did not save properly.

I am using Firefox version 82.0.2 (64-bit).

Two questions: 1/ Is there any way I can get the pinned and open tabs back from the previous session? 2/ What can I do to avoid this issue EVER happening again.

Thanks!!!!

When i close my "main" Firefox window and after that the opened popups, this breaks my "restore previous session" setting.

this is not the first time because sometime i forget to close the popups first...

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

I think it was update, my pc restarted. But it usually asks weird. I lost all windows and all tabs. Yet in library/history under restore windows, there is nothing! There was some json file, from which you could get tabs. I tried it last time and it didn't work. Also firefox wasn't even running at that time and previously i had all windows and tabs... Are you kidding me???

I lost like hundreds of important tabs.... Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa............

Hi. I would like to restore my previous session when I open Firefox (last version of the browser installed). The option is turned on, but nothing happens when I close the browser and I open it again. The support says I should see "Restore previous session" after "New Private Window", but this option is not there. In the history, the list of recently closed tabs is always empty, there are juste one or two links in the recently closed windows (it seems to be a random list). Can someone help me ? I don't understand why it doesn't work. Thank you :)

Suddenly tabs won't close & hitting "Command" & a link opens a new window instead of a new tab. Anyone know how to make tabs close & also how to revert to allowing "command" + clicking a link to open in a new tab & not a new window? I've tried shift + re-opening Firefox & I tried 'safe mode' & it's still happening.

Hi and thank you in advance. I am in a serious dllema here. I was just about to hire someone to do this work on upwork or fiverr or the like when I did a search and confirmed that my saved passwords are also stored in this file. I have tried Everything I can find to get my 90 megs of tabs back, which a stupid verizon hot spot network log in screen crashed and I am just about at the end of my rope. I

have been through hours and hours of fooling with this. Already tried this site, https://json-csv.com/ pro version, this site https://www.jeffersonscher.com/ffu/scrounger.html and the firefox add on moz-extension://8fb59157-3fd6-43ac-982e-f27264d2874f/app/app.htm and a few other tools that are outdated or don't work on my system.

PLEASE, I will pay someone who is officially from Mozilla if necessary, I just need my tabs back.

I closed firefox (all three windows), and when I reopened it, it opened the two background windows... but NOT the main window that had all my tabs and pages and projects. Thanks, Firefox.

I *could* go through my History, and see if I remember WHEN I accessed each tab, and TRY to rebuild it, but that is INSANELY ANNOYING and takes upwards an HOUR.

When i switch on my computer i have to make sure that i open Firefox and restore the previous session before i do anything else.

For example, if you click on a link in an email - and if Firefox is not open - then it will open Firefox and you have lost access to your previous session tabs.

Yesterday, when i switched on the computer Adobe wanted to remove a program - so i uninstalled the program and then it opened a page in Firefox so i lost 50 tabs. Sigh.

SUGGESTION As well as having the option to restore the previous session could we please have the option to restore the session before that? I think this will make a lot of people very happy.

Hey!

First time I get that, I usually lose my tabs due to my mistake but this morning after starting my PC all the tabs were gone with no option to restore or any error message. I backed up my previous session json and other files by hand but every time i copy it back into my profile folder and rename it sessionstore.jsonlz4 it just gets deleted after I open firefox and none of my old tabs get loaded. I scrounged the files before and saw that they contain my lost tabs, I just can't seem to restore them. I tried reinstalling firefox too but that didn't help.

Did the restore system change or is the backup corrupt ? Thanks!

Fred

Hello, my Mozilla Firefox is hanging when I have about 50 tabs opened. So I have to kill the browser and restart it. After a few hours of work I have to do that again. Any ideas/suggestions?
