I followed the instructions at [[Unload inactive tabs to save system memory in Firefox|https://mzl.la/3AdRbLx]] but I still occasionally see the tab refresh when I select it. I start with a search on Bing, click an article to open a tab, follow links from there, back to the first tab and select another. I repeat this until there are several tabs open. Sometimes the page refreshes when I switch back to one that I previously reviewed. Is that controlled by the option browser.tabs.unloadOnLowMemory? if so, it doesn't appear to be working. [Edit] - The last time this happened I checked my system and found 10gig used of 64gig installed. I'm using the most current version of FF 120.0.1 on Windows 11 Pro v 22H2.

When searching with google it always opens a new Tab with some not working Address. Whether i just search or click on pictures or look at a picture more in detail it always opens this tab: Look at picture: At this point it is really annoying and in the settings of the browser i don't seem to find a solution. Please help.

New Firefox is making me angry everytime I use it. New tabs are doing what they want, they never open near the site that i'm watching. Sometimes they open in the middle of other tabs, sometimes at the end. That is so problematic and frustrating that i would download an opera if i can't change it. I use about 90 tabs and that's the way I'm using Internet, I won't change it. I have searched in settings but there is nothing. Old mozilla haven't done this. Can someone help me?

I'm facing a bewildering problem with Ctrl+Shift+T, which has only started in the past few hours and persisted through troubleshooting.

In short, it's opening a default new tab when I press that combination, rather than reopening the last closed tab, as is its normal function. The problem is not that the tabs themselves are lost -- the "Reopen Closed Tab" drop-down menu entry is still available on right-click, and seems to function as expected. Similarly, I checked about:config to see if there was a problem with sessionstore or sessionrestore, both of which are at their default settings and can't be causing this. Rather, something about the combination itself is no longer working.

I ran Firefox in Troubleshoot Mode to see if any of my settings were causing this. The problem persisted there, so that doesn't seem to be the case.

A little over a month ago, I got a new phone and synced up my desktop and mobile (Android) Firefox tabs, which I hadn't done previously. This is really the only thing I can think of that would lead to any issues, but it's impossible to match the timeframes -- I noticed this problem today, five hours ago. (The failure for ctrl+shift+t to work includes tabs that were opened from mobile sync.) I make heavy use of this keyboard shortcut and would've noticed it earlier if it started earlier.

Something about Ctrl+Shift+T itself is not properly being 'translated'. Ctrl+T works as expected (opens a blank tab), which is the same thing the Shift version is doing. Both my Ctrl and Shift keys are working fine in other respects (e.g. shift key capitalizes letters and adds special characters), so it's not keyboard hardware. It's not "inconsistent" -- it consistently works for everything else, and consistently doesn't work for this.

I'm using Firefox 122.0 on Windows 11.

Hi, Since few weeks ago, firefox never restores my previous tabs/session (I lost a year worth of tabs..), no matter what/how I tried, it keeps starting with a clean session, not even the history in there. I tried: Deleting profile, creating a new one Resetting Firefox Fully delete FF and delete the profile folder Heck, I even used librewolf, and even FF on linux and also Librewolf, same issue!!

I notice this happen once I enable the sync (login to my account), there's no setting in my account says to never restore the session or something similar.

How to solve it?! I need to have the tabs open again..

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!

It only backs up the tabs from your last close, so if you had a problem and closed twice, all your tabs are gone. There are many many easy ways to change it so this can never happen to people anymore. Why has this not been fixed after all this time? I am a retired IT pro and this has even happened to me. It is horrible. What can users do to not have this happen, since the developers apparently can't be bothered? And please don't tell me not to keep so many tabs open JUST because the browser sucks at protecting them. Any good news appreciated. Thanks.

I am on a brand-new machine and having trouble setting up the Firefox browser.

When I click on a link it opens in a new window with all the tabs ready opened.

How do I open a tab without opening a new window?

Also, how do I set Yahoo.com as my default search engine?

Thank you for sharing your wisdom

I am in the habit of generating related tabs across several windows. Say, 5 windows and there might be 13 tabs that I want to organize onto one, new, window. How can I do this?

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...!

I used System Restore in Windows because I lost my Search Engine in Firefox and it didn't exist in "Customize Toolbar" option. I researched how to get the Search Engine back but nothing worked. I thought System Restore would solve the problem. Now I can't restore my previous Firefox session. And I can't find a sessionstore.jsonlz4 file. I read you have to rename a file in sessionstore-backups folder to sessionstore.jsonlz4 but I don't know which file to rename. I also read you can restore a recent upgrade.jsonlz4 but that is dated 3/5/24. I loaded previous.jsonlz4 file using the Scrounger tool but that didn't restore the session I had. (The previous.jsonlz4 file is dated 3/22/24 about 45 minutes ago.) I want to restore the session I was using earlier in the day. And "Restore Session" option has disappeared from the Firefox History dropdown menu. I tried the "Restore Firefox" option but that didn't help anything and it made my dropdown menus disappear. I have no idea how to get the session back that I was using earlier in the day.

I have been using the "Restore Previous Session Option" fairly often for years, but within the last few weeks the option is no longer there.

I had tried to use the Settings > Open Previous Windows and Tabs as a workaround, but it doesn't appear to be consistent.

Did something change in a recent update, or is my installation broken somehow? I tried refreshing Firefox but that didn't bring it back.

The article here shows what I am referring to and has a screenshot of where the "Restore Previous Session" option was: https://support.mozilla.org/en-US/kb/restore-previous-session#w_when-session-restore-occurs

Anyone else have this problem? Is my installation broken? And how to fix?

Hi, it has occurred to me that I lose the browsing history of tabs that were open for a long time. By browsing history i mean the sites that show up in "Go back one page" arrow. The issue is that after a website has been open for some time (this seems to be in range of days, perhaps weeks) the browsing history of that tab is forgotten and the Go back one page arrow goes blank. I would like to be able to keep this history for eternity, is there any way to enable that?

To be clear, I use the feature to save tabs of my previous sessions and also the Simple Tab Groups extension.

Thanks in advance, Alex

Firefox changed the design on tabs and other features some time back. The whole user experience has been worse since the UX design was changed. For example, it's impossible to find out without going through tab after tab, which one is active and playing. I wish there was an option to reverse back to the old design.

I was running 8 Windows with about 12 tabs per Window. AND I had it set to Continue Where You Left Off, so that each time I closed and launched FireFox, ALL Windows with ALL Tabs would open. No problem. Easy.

This morning, Firefox crashed and LOST EVERYTHING. Why did it happen? And how do I get them back?
