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.

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

Any else seeing this lately?

1. **Navigation Issues**: Firefox fails to correctly navigate forwards or backwards through browser history. It often does not load the intended previous page, skips pages, or refuses to load a page entirely, requiring the user to close all tabs and manually re-enter the URL.

2. **Loading Issues with External Links**: When opening links from external applications (e.g., email clients), Firefox frequently fails to load the expected webpage. Sometimes, it does not load any page, or it loads to a blank or the home page despite the URL being visible and highlighted in the address bar.

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?

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?

I had several windows open each with different tabs in them.

I shut down them down and switched off my Mac.

On restarting my Mac, one of the windows had disappeared from the restore session. I've checked my History but the tabs don't appear there.

I'm using the latest version of FF on a Mac Air M2

Please advise.

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

My computer has been having some problems lately: Any rough handling might trigger the computer to shut off instantly or restart automatically. This is likely a hardware issue, probably a loose battery or something. The Firefox-related issue is that sometimes, upon turning the computer back on, something odd happens to my browser session: It is set back to three months earlier. The recent browsing button show everything having been browsed three months ago; but when I check my history, all my most recent tabs are there. This is tedious whenever it happens, as I have to spend about an hour manually opening everything I've lost (that I want to keep) from history. If there's a way to bulk re-open a bunch of tabs, I don't know how. All that has become something of a routine annoyance (it happens maybe once every two months) but I'd gotten used to it and it wasn't really an urgent problem. Today, however, I dropped my phone on my laptop, triggering a restart and a blue screen with a message that said something like "we're cleaning things up for you." It's what usually happens when I drop something on or accidentally elbow my thinkbad. (More commonly I move my computer a little bit and it just shuts off completely, goes black.) Before this happened I was due a firefox update, and I found it had done so when I turned my computer back on. I realised immediately that I had lost some tabs, and I assumed that it was just a three month setback. Upon opening my recent browsing though, I found out with horror that I'd been set back nine months. I cannot restore from a nine month period manually. I don't have the time, energy or willpower. I'm asking here if anyone knows how to bulk restore tabs from history or how to restore my session to how it was just a few hours ago. Thanks

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.

In the tabs column,it is very difficuit to close certain unwanted tabs ie,when we open 9..or 10 tabs simultaneously.There is no close button for each tab when we select to close the particular tab.So we kindly request you to provide close button to each tab bar.(right click option is available,but it's not confortable).

how to permanently keep the warning about closing multiple tabs?

Every so often, probably due to an unseen update, when I press the red X at the top of of a page where multiple tabs are open, to see how many tabs are open, they disappear, and the preference option to not close multiple tabs without warning (which says the # of tabs open), has to be turned back on.

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

Sometimes randomly, but happens often when using EBay, clicking on link opens to a new blank tab. The tab lists about:blank. Sometimes the link will work after a couple tries, but sometimes can take more than 5 times to get the link to open. On some sites it can happen randomly, but it’s pretty repeatable while using eBay. I have deleted the app from iPad, did a hard reset, and reinstalled the app, but there is no difference in behavior. Behavior started with the most recent Firefox iOS update. Firefox iOS, Firefox 124.0 (39709), iPad iOS running all latest versions and updates as of 03/24.

For ages I've had my tabs automatically restored when opening Firefox. But as of the last few days it won't. The old links are saved so I can restore them one by one through history but that's not automatic. And if I click on restoration in History it will bring up a whole bunch of old tabs not neccessarily from the last session.

I'm on the same computer as I've been for over a year, so I don't know what what the problem is. I've searched on it and tried to re-check the box for this function. But it won't apply...

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

Hello! Can you help me sort out a little problem? I am reaching out to seek assistance with a specific issue I am encountering in the Firefox browser.

In my previous browser, when opening new tabs, they were considered active even if I did not immediately switch to them. This behavior allowed me to open multiple tabs, for example, by using the mouse wheel to open several videos from the main YouTube page. Subsequently, when closing the main page, the videos would be available in the order they were opened, facilitating a seamless viewing experience.

Upon transitioning to Firefox, I have attempted to configure the browser to replicate this behavior using the Sidebery extension. However, even with the extension, new tabs are not recognized as active unless I explicitly switch to them, making it challenging to maintain the desired tab activation order.

I have explored various settings and experimented with the Sidebery extension but have not been successful in achieving the desired result. In contrast, the Yandex browser, with the "Switch to the previous active tab when closing a tab" option enabled, behaves in the manner I am accustomed to.

Could you please provide guidance on how I can configure Firefox to consider new tabs active immediately upon opening, regardless of whether I switch to them immediately?

I added pictures to make it clearer what I'm talking about.

Thank you for your time and assistance.

Hi,

I use the latest FF for MacOS.

When I "close" Firefox by clicking the red cross in the top left corner of the window, I lose all open tabs when I start again despite having the option of restoring the previous session checked. When I "close" the whole thing (right click on FF in the Dock, Quit, and then re-open), all my tabs are back normally.

So basically every time i click this red cross, by mistake or not, I lose anything that's open.

Feels like I did not have this issue before.

Anyone has a workaround or experiences a similar issue?

Thanks!

The google.com on Firefox on android is not working it displays a white screen each time I open Google.com
