Got up this morning and FF said all my tabs were crashed - GAH! Could not open ANY new tabs, not even a blank tab, without getting this message. Clicking on restore tabs did nothing. Closing & opening FF did nothing. Cleared startup cache & uninstalled ublock origin (the only extension I had) but that did nothing. Refresh firefox did nothing (except lose some of my preferences). Went to about:crashes and all it says is "No crash reports have been submitted." Every other suggestion I found online was beyond my comprehension. FF DOES work in troubleshooting mode only, but I lose some important functions in that mode. I've been using FF almost since it was born and have NEVER encountered a problem like this before. I hope someone can help!

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

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.

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.

I have custom URL's set when opening my homepage. For the last few weeks, Firefox has been opening tabs from the last session. I've checked the URL's and they are correct in the settings but for some reason they're not loading properly.

These are the correct URL's in the setting page. https://www.etsy.com/your/shops/UiJewelryMaui/tools/listings/state:sold_out,sort:sold_out_date,stats:true|https://www.etsy.com/messages?ref=seller-platform-mcnav|https://www.shopify.com/|https://maui.clareityiam.net/idp/login|https://outlook.office.com/mail/|https://calendar.google.com/calendar/u/0/r?pli=1|https://www.microsoft365.com/?auth=2|https://www.canva.com/|https://hawaii.infinitecampus.org/campus/portal/parents/hawaii.jsp|https://mauinews.org/pub920.htm|https://www.mauicounty.gov/Bids.aspx?CatID=19|https://hiepro.ehawaii.gov/vendor-dashboard.html|https://us2.admin.mailchimp.com/campaigns?ref=plums_nav&_ga=2.43380451.756894218.1698551103-1299448220.1698551096#f_bucket:recent;t:campaigns-list|https://hawaiicovid19.com/

However, the pages that load at start up are not these URL's, instead they're opening with the ones in the photo I provided. How do I fix this or do I need to select a different default browser?

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?

Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

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.

I'm having the same problem as this guy.

I have a large number of open tabs in Firefox on my iPhone, a mixture of old and very old. I've been trying to go through the tabs and deal with them -- in some sense they are all todo items that I left open at least semi-deliberately.

If I tap on a thumbnail to load a tab, Firefox instead loads a blank page. If I tap the address bar after that, Firefox loads the new tab page, not the site corresponding to the tab that I selected. If I tap and hold a tab's thumbnail, Firefox crashes.

It was the case temporarily (possibly a bug) that some of these tabs would place a TLS failure icon in the left of the address bar when selected, while the blank page was displayed. Tapping on that would display the tab title, but not the tab URL. No longer is that TLS failure icon ever visible.

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

Email removed for privacy

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.

As long as I have an incognito window open, Firefox will reopen old tabs everytime I open a new "regular" window, even if "Open previous windows and tabs" is unchecked.

I have many tabs open at the same time and I'm noticing tabs from Urban Dictionary in particular are automatically changing to suspicious sites, quite a few porn sites in fact.

Is this something Urban Dictionary is doing to direct viewers to sponsors or is there a bug in my FF browser?

So I enabled push notifications for Google Calendar. Every time there's a notification, Google Calendar ask if I want to enable "Switch to this tab" for their notifications. I accidentally turned it on, then I managed to turn it off. Except it now keep asking me if I want to enable it.

Looking at the settings, the only two options available are "Always ask" and "Yes", with no way of just saying no... why?

This is the procedure I followed:

Close firefox

Copy previous.jsonlz4 file to the main level in the profile

It has all the tabs i used to have in it because I made a backup a few days ago

Rename the file to sessionstore.jsonlz4

restart firefox

I get the same single tab I had before i did this

when i go to history tabs, all that is there is the single tab i currently have

Appreciate your help/gary

I’ll use the example of movie times. In the IMDB app you can pick movie times, that link sends you to my web browser (Firefox) which opens to the homepage, but that’s it. It doesn’t do anything else, it doesn’t even attempt to open a page. It’s been happening for a while. What am I doing wrong g?

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.
