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.

Hello!

I can't figure out what setting to fix this: every time I click to open a new window, about 35 tabs automatically open up that I have closed several times in the past. I simply want one new window without any previously opened tabs.

I've tried:

• clearing my entire search history several times
• shutting down Firefox and reopening (which opens up all those tabs)
• uninstalling Firefox and reinstalling it
• initiating the latest Firefox updates
• restarting my computer
• turning my computer on and off
• looking through every single preference in my Firefox settings (I've unchecked anywhere it talks about opening tabs)
• reading various articles on Firefox's support page and on other support websites to try to figure this out (there's little info on this problem; the support is mostly about how to save previously opened tabs

Please help! I'm tired of having to close down all these tabs every single time I have to restart my computer or have to shut down Firefox. It slows down everything I'm trying to do.

Thank you!

I found an answer to this question, but I need it in English; how to do this if you're not a programmer. The new feature is beyond annoying, so if someone wants to work on making it optional, that would be a super improvement, but I'll be happy if I can just turn it off! Thank you

Hi everyone,

My computer crashed while updating from Windows 10 to Windows 11. Unfortunately, I had someone look at it and he formatted my hard drive and only did a partial backup of files. I thought my Mozilla Firefox account was syncing, but it seems like it did not happen in a while. Does anyone know if there's any hope in recovering the lost tabs and bookmarks? Any help would be appreciated. Thanks,

Kenan

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.

Often times when I open a new tab, I get a dot that goes back and forth and will not open the tab. This seems to happen if I don't use Firefox for a few minutes. It's like its trying to open but can't.

Hi.

This message has three sections: little background, little rant, and little help from my friends.

Little background: I use PCs since Commodore 64, and internet since dial-up modems. Apart for some curiosity attempts with other browsers, I always used Firefox. Back then you either could do some DIY or you were done for. So, I am not a noob. And yet I am not a programmer, and do not have to damn be in order to use a damn internet browser. I have no words to express how negatively the choice of changing the behavior of the X button, to make it disappear when a certain amount of tabs are open, affects my user experience with Firefox. I tolerated it version after version. Found mentions of about:config tweaks which never worked. Found mentions to css codes which seemed so complicated that I just gave up (I also don't have much capacity for such things atm). I was ready to get rid of Firefox today after all this time of being loyal. I would have, if it was not for Cor-El. (Cor-El you can put this testimonial on your website if you'll ever start a consulting business).

Little rant: I SO SO SO SO SO SO MUCH HATE bad UX Design! And the FIRST definition of bad UX Design is when a designer imposes their own tastes and preferences on the users, or makes assumptions (based on their own usage) about how users would do things. I don't give the lesser s... if Firefox's UX Designers usually only have few tabs open, or don't mind clicking on a tab to make the damn X button appear, or would gladly abandon their beloved ergonomic mouse to buy a standard one with a mid button just to close tabs, of whatever the f... was going on in their minds when they decided to remove such an ESSENTIAL FEATURE!!! This change is WRONG! Nobody asked for it, nobody wants it, nobody likes it. The X button was not disturbing anybody. WHY must we tweak some f... about:config setting or ask in this Community for some css code to get back what should have never been removed!!!??? DO YOUR JOB, which is to make OUR user experience better, OUR, not yours!!!

Little help from my friends: After quick searches over a long time where I couldn't dedicate more resources to this, I came here determined to dig deep to find a solution. And I've found a few posts with answers from Cor-El. I followed his instructions in THIS post to configure a css file with the code that he provided in THIS other post (because I thought I didn't want the delay offered by the code he provided in the former post). Problem solved.

Now a question for Cor-El: Is it just me or the solution with the two browser.tabs settings does not work? It's the first thing I tried. I went from 50/50 to 200/200 to see if size matters. But no chance. Maybe there is another setting that must be activated for these to have effect? Or was their effect on the X button removed in newer Firefox versions (like the UX Destroyers really hate us)? Btw, I wanted to see how the delay thing would work, so I tried the code you gave in the first post, and it didn't have any effect. Whereas the code you modified for a guy in THIS post works perfectly. What could be the reason?

And 2 requests: - can you make some guide or pinned post about this, where you put together the info you gave in different posts? Something with your super easy instructions how to create a css file, and the two codes (with and without delay). And if the browser.tabs solution can still work, that too. All info in one single place, easy to find. - can you point me to a (possibly ADHS friendly) resource to more css codes for other useful tweaks, and to an explanation of what all about:config settings do? I like to tweak things to my needs. But I get overwhelmed if I have to read through tons of material. Thanks :)

Bonus Material, Little Rant part 2: It's good and nice that people help each other and I am thankful, but it does not need to come to this. Sure, I've read that the (ridiculous) reason behind the choice of making the X button disappear was to avoid accidental closure of tabs. But WHY taking for granted that we are some !diots who can't even use a mouse properly? And even if it happens once, we can still go to the damn "recently closed tabs"! But no, they had to remove the X button for all of us, to prevent a bunch of !%#@! from maybe sometime accidentally closing a tab. Why not just adding an option in the settings (NOT in some hidden "about:config") to let us choose if we want to have the damn button or not? Btw, a lot of these about:config tweaks are really useful and not dangerous at all and should imo be included in the normal settings. Keeping things simple and tidy does NOT mean reducing options. Unless you're Apple.

Please God-zilla let these [censored content] UX Designers read this post.

Amen and happy new Xear.

Ok, I've resolved this in the past, several version of Firefox ago, under windows. Firefox crashes silently, open it again and no tabs are restored. Open firefox again and look in recently closed windows and the one with my tabs is not there, only little utility windows that are popped up when I log in at the coffee shop, so my recently closed windows are overwritten with windows with no tabs.

So I go to my profile sessionstore-backups folder and copy it to the desktop. I have 6 files, previous.jsonlz4, recovery.baklz4, and recovery.jsonlz4 at around 8 megs in size. I copied each to the folder one level up and renamed them sessionstore.jsonlz4, and each time restarted firefox. All that opens is a blank tabbed firefox window.

There was never an existing sessionstore.jsonlz4 file anywhere I could find, even with firefox closed, this file never appears anywhere I could find it. Searching files with Windows was also unsuccessful.

I feel like I have captured the files with my tabs, based on the date modified, several were from before the crash. Why can't I find a working tutorial on how to restore my tabs? Nothing I've found on the support site works though I follow the directions exactly.

Thanks

Hi, I have recently update my Win system with everything including Firefox. And now when I open new tab there is the same Firefox icon like always, but when I it is loading new page then its new X. When it is done with loading it changes to OK icon of the dedicated page. Is this X normal? Thank you

My Firefox window with 15+ tabs just crashed. I watched a YouTube video and the solution offered doesn't work. How can I restore them? And does Firefox really not have a way to speak to a human being??

Just lost it.

How can I import or to which folder do I import bookmarks so they show up in the shortcut rows in a new tab? I'm trying to get away from Opera but I love the shortcuts displayed on a new tab. I tried copying all the appropriate bookmarks to the bookmarks menu folder and why they are in the folder they dont display in the shortcuts.

The imagine shows where I want to import to.

I recently downloaded Tree Style Tab. I still see the horizontal tab bar. I would like to hide it. However, I have tried just about every answer I could find on Mozilla, Google, Reddit, and any other websites that offered solutions. Nothing has worked since the last update. This includes the "type in about:config, toggle to true, open profile folder, create userChrome.css file, copy and paste xyz code, save, and restart Firefox" route.

Any help would be greatly appreciated!

Hi, As far as I know, Firefox hasn't recently updated but somehow my address bar is now below the tabs. I have searched everywhere and can't find a solution. Searching shows that this has been happening repeatedly for years with people having to go as far as adding code to configure it. It has never happened to me until the change appeared randomly today. Am I missing something, or has the option completely (and pointlessly) disappeared? Please point me in the right direction to restore the position of the address bar. Thanks.

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.

Yesterday, I was invited to update Firefox on my desk-top PC running Windows 10. When I did, all of my open tabs were absent from the new version. Luckily the old version was still open with my open tabs. Today, my old version opened again with the open tabs and a window that said the automatic updated didn't happen. It invited me to update again. I clicked on "More information" and it went to an error message. My question is, how do I save all of my open tabs when I update Firefox?

I really appreciate the container tab option for my browsing, as it affords me more privacy and I am a stickler about my privacy. However- I have been having an issue with links that I am attempting to open in a specific container that will load, and then immediately reload into the tab without a container. This has happened several times. The most recent example is that I clicked on a link from FB, a site I tend to avoid, and specified that I want it opened in a FB tab, as I don't trust them not to track me beyond that. However, the link loaded in the FB tab and immediately again with no container whatsoever. There was no request, no warning that I had set up the "multi-account container" and did I want to use it in the designated container... nothing. This has happened with links before as well.
