Firefox Community Forum

Tabs not opening. Cleared cache and history. Also went to "Trouble Shoot" restore did not work. Uninstalled then reinstalled. Still did not work. Changed Profile. Still not working. Got to this website by typing in website using Safari.

Hello Community! Just updated Monzilla and my Sidebery Tabs are mostly blank now. There is one tab still functioning, but all other tab links that I had organized for my business are now blank. Yes, my Sidebery is turned on.... This has never happened with an update.

Is this due to the new sidebar from Monzilla? I love my Sidebery, spent a lot of time organizing it, and am not as keen on the new Monzilla function, but even if I change over, I want to use my Sidebery as a means to transfer everything to the Monzilla sidebar.

Ideas anyone?

Thank you!

We have been using firefox as our default browser for over Ten years. We have several internal web pages created with google sites, with simple google sheets containers that have been working fine in that period. As of two days ago, the pages started displaying incorrectly in firefox as shown in attachments. Have tried disabling trackers and extensions and emptied cache as well as making sure firefox is fully up to date. This is happening on multiple terminals at several locations. Safari and chrome browsers work fine. Any troubleshooting help appreciated or if this is a known bug?

Since the most recent update (137) I have been having an issue where when I switch tabs to an existing open tab, occasionally that tab will be moved to the end (far-right) of the list of tabs. I find this extremely annoying as I often am using tabs to organize what is related to what, and this is undoing my organization.

I can't quite see what the exact trigger is - it's not every time, but it fairly often. It sometimes happens when I try to 'switch to' my current tab, and sometimes it will happen when I'm switching to a different tab.

I need someone to phone me to got step by step to stop tabs from loading. I see the answer but I am not a computer guru so need someone to assist me step by step to stop all my historical tabs from loading.

When I click the plus button to open a new tab, or press Ctrl+t I want the tab to open in a specific container. To have a default container so to say. Is this possible?

Trying out Vertical Tabs, but when doing so an unremovable Flexible Space appears in the Toolbar. You can move it around, but not remove it (image #2 is trying to drag it into the Customise Toolbar icon list). This thing disappears when switching back to Horizontal Tabs.

Any clue why this is happening?

When dragging or selecting a tab it forcibly moves it to the end of the tab bar.

As it would if you pressed move tab to the end, But without actually selecting it. Not sure why it's doing this and nothing is selected and it didn't happen before the update. And it only happens every once in a while.

Tough there is an option in Settings that says "When you open a link, image or media in a new tab, switch to it immediately" that can be deactivated, my browser always switch to the new tab/open link/image/etc. It's frustrating. Using Mozilla for Linux Mint mint-001 - 1.0. Version 137.0 (64 bit)

I'm fed up with updates. Whomever decided to move opening multiple tabs to the left or right had of the desktop has their head up their ass. It takes up significantly more desktop space now and is nowhere as easy to use as when they were on they tiop of the desktop. Plainly - IT SUCK - no improvement on my 27: iMac

In recent Firefox versions, the behavior of window.open() has changed. When opening a new window with an empty URL (), Firefox opens a blank tab (about:blank) and then loads the specified content. However, the about:blank tab may not close automatically as it did in earlier versions.

So when i first updated to 137.0 tab groups were working fine, then one day i couldn't create any more. I had a previous tab group, but when i deleted it, there was no way to make another. I tried dragging tabs on top of each other, tried right clicking a tab to "Add Tab to New Group" but there wasn't an option. I updated to 137.0.1 to see if that would fix it, and it didn't. I then tried to uninstall and reinstall still no. I turned my computer off and then on again and also no.

I'd really appreciate any help with this because i'm kinda tearing my hair out trying to find out what changed.

I currently have Firefox to open at startup showing three different websites. When I open a new window, the same three sites are open. I would prefer all new windows to open with one new tab only. I don't much care whether that new tab displays some sort of blank page or home page or a website I have chosen or whatever.

I can't find a setting or an extension which allows this. Can anyone help?

Hello, Win11 Pro 24H2 Firefox 136.0.2 (64-bit)

When I alt tab over to my firefox windows and then press ctrl t to open a new tab it does not work most of the time. I have to sit and hit the keys 10-20 times before it will allow me to open a new tab. Do you have any idea why this is happening? I have tried safe mode with firefox and the issue persists so it is definitely not any extension that I run.

Can anyone please help me figure out why can't I access my multiple open Firefox tabs on my Widow 11 desktop unless I open a new tab, and then click on the three line Firefox app menu symbol, then select "History" and then go back? I don't even have to choose a function under "History". I just go back to the tabs and they have become available to be selected and activated. This fix is only temporary and may have to be repeated several times in one session. The misbehaving tabs show up in a horizontal row over my toolbar area (sometimes as dark panels after an update) but clicking on them just causes the row of tabs shown, or the vertical list of excessive multiple tabs, to disappear. I tried selecting troubleshoot mode, but did not see any indications of errors. This problem only began after my last Firefox update and does not go away after a Windows reboot.

Don't understand WHY every site I visit, ends up as a Tab. I would like to have ONLY the ones I need! Also, where is the tab that I used to have to allow some sites to post?
