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!

Private tabs disconnects the second I switch to another app or turn off screen. And when I switch back tabs basically opens again. So if I try to listen to a podcast from a private tab, it will stop, if there was any data typed, it will be lost. I disabled all power saving settings on the phone, it didn't help. And I didn't find anything in Firefox settings I'm using redmi note 10 with miui 14 global. Firefox from Google play. And UBlock and Privacy Badger are installed

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.

After updating to 125.0.1 (64 bit) all my existing tabs were wiped out. Restoring the tabs does not solve the problem. Every time I close Firefox the tabs disappear.

For the past three days every time I initially open Firefox on my iPhone, I get a page that pops up. I'm assuming asking me if I want to switch my Firefox to a different language. I can't really tell what it's asking because it's in a different language. How do I stop this from happening? It is extremely annoying.

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!

I am watching a Twitch video on Firefox. When I open a new Firefox tab and drag it to another monitor, the Twitch video skips forwards about a minute.

I also occasionally notice skips or pauses when I switch from one tab in the same window back to the Twitch playing tab.

Is there any way I could fix these problems?

Recently on my iPad and iPhone, clicking valid links in either my browser (Firefox) or e-mail (Outlook), a new tab will open to the “about:blank” page, and nothing more.

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

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

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!

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.

Best Wishes

Sooo I had tens of tabs open, with intention to keep them - I couldn't find an option to save all of them, so decided to update the app, just in case FF caught up with some functionalities I've seen in my other browsers - bookmarking all tabs, namely.

After I've updated, all my open tabs are gone and "recently closed" is empty. There's no way to have the tabs back.

I don't expect there's a way to solve this problem, but I'm posting it here just in case, and at the same time marking my segue to Safari.

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 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?

When I am deleting emails, I frequently end up with the same email as most recent in my inbox and thus automatically selected. This opens a new tab with the same email as content and soon my tab section is filled up with multiple versions of the same few emails and the inbox tab pushed off the screen.

Can there not be a setting to open up the existing tab if it has the same content. Or alternatively a way to pin the folder tab (normally inbox) on the left of the tabs permanently.

Other tabbed applications do not open up multiple tabs with the same content.

Yes I could shut the unwanted, repeated tab each time Thunderbird opens it, but I don't want to have to.

This seems like an easy feature? Please??

I am afraid to update to Firefox 124 for fear of losing the existing order of 100s of open tabs if the default setting of ordering tabs by "Recently Opened" kicks in before I have a chance to change the setting to "Tab Order". Can anyone help me? I'd like to upgrade to 124 if I can do so safely!
