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.

Hello! I'm trying to configure Firefox not to switch from the current tab, when I open multiple bookmarks by either middle click bookmark folder or right click the bookmark folder and select Open All Bookmarks. I've already set about:config browser.tabs.loadBookmarksInBackground True browser.tabs.loadDivertedInBackground True browser.tabs.loadInBackground True

If I'm browsing a page, and then decide to open several bookmarks that are in a bookmark folder, either via middle click or right click->Open All Bookmarks, Firefox will still switch to the first open bookmark.

I've tried Shift+Middle click and this one opens the bookmarks, without switching from the current tab. And Ctrl+Shift+right click->Open All Bookmarks and this one opens the bookmarks, without switching from the current tab.

So how do I configure Firefox to just use middle click on a bookmark folder, and then not have it switch to the first open bookmark? Thank you!

When I open Firefox to my home page any additional tabs that I open keep crashing. The page tells me that it has crashed and there is a restore tab button there but that doesn't work and the crash message just comes back.

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 I read these articles and they doesnt help to resolve the problem https://support.mozilla.org/en-US/questions/1349609 https://support.mozilla.org/bm/questions/1206172 https://www.reddit.com/r/firefox/comments/ip88y7/firefox_is_preventing_windows_10_from/?rdt=53488

Problem: I have Win10. Firefox 107. I have noticed that if I have opened only regular/textual web pages in my tabs like news/articles then PC goes to sleep after specified time of inactivity. But if I open in the one tab some media content like videoclip/animation/movies and put media content on pause then PC doesnt go to sleep after specified time. PC goes to sleep only by manual command (Start>Sleep). Even If I close the tab with media content PC doesnt go to sleep after specified time. I should or totally close the browser with all opened tabs or manually select Start>Sleep.

Could you help to resolve this issue ?

On the screenshots are shown that some of firefox processes couldn't stop making some activity, every second they make some web request or disk operation. May be this is reason why PC cant go to sleep. But again, this is happen only or some media content is put on pause or some tab with media content has been closed.

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..

Facebook used to be stable so while I was writing something, I could open other tabs to research things and go back to facebook and pick up where I was. SOMETHING HAPPENED some months ago, maybe a year (more?) and now I only have a short window to return BEFORE THE TAB REFRESHES and FLUSHES WHAT I WAS WORKING ON, DOWN THE TOILET! Is FACEBOOK OR MOZILLA DOING THIS AND CAN IT BE STOPPED!!!!

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!

I have pinned various shortcuts in the New tab to link to websites I frequently use. I use two different laptops and both are configured the same. However the New tab randomly clears the pinned shortcuts. I have attached two screenshots illustrating the changes.

I'm not aware of anything I do that caused the shortcuts to be deleted. When they are pinned I think they should be there permanently.

Just recently been getting yahoo search engine results to open in new tabs rather than the same tab. I have searched for other users that have the same problem and have done the tracking protection thing and deleted cookies, but nothing helped. Also tried Troubleshooting Mode and it still persists. Any other ideas that may help? I'd appreciate it.

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.

Hello. I experience a problem that occurred 2 days ago. Firefox seems to ignore my preferences of opening previous windows and tabs, also it ignores pinned tabs. Some of websites disappear from the history (let's say i opened few windows to check if tabs will be saved by firefox, closed browser, opened it after few minutes: tabs are gone, history has only few of websites that were open. I tried to look for the problem by myself but failed. I will be grateful for your reply, thank you in advance.

Everytime I try to open a tab on my Firefox window, it loads for a second before a blank screen saying that my tab has crashed. The only times I can open a new tab is on a private window.

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.

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.
