Firefox Community Forum

Hi, I have the settings of 'General > Startup > [checked] Open previous windows and tabs' on. Most of the time it works as expected, but there are several occurrences when all of the sudden all of my pinned tabs are gone. When this happened, I usually tried the 'Command + Shift + T' to restore them. Sometimes they came back, some other times, they don't.

Can you fix it?

It's starting to get really irritating because I can have >12 tabs pinned and it's troublesome to have to remember them all in case this happens again in the future.

Thanks!

Recently, whenever i have to quit firefox, my tabs have all disappeared upon opening. I have tried all the suggestions in the Mozilla help and nothing seems to work. This used to happen from time to time which was frustrating but now it happens every time I need to quit firefox. "Recently closed tabs" and "recently closed windows" are greyed out when I try to use that. and there is nothing in "restore previous history". Thank you for your help.

I regularly use a website which intercepts command-option-up and command-option-down for its own navigation. This is a central part of my workflow with this website, and without it it becomes completely unusable.

After updating to Firefox 140.0.4, these shortcuts are now used by the browser to switch tabs. I have not found any way to configure this. Am I missing some obscure way to do this or is this just impossible?

I imagine this change was made to support vertical tabs, but I'm not using those, so the command-option-left and command-option-right shortcuts make more sense for my horizontal setup. (I don't use those shortcuts either, though- I use ctrl-tab and ctrl-shift-tab!)

I have a new mac, an M4 mini, and I set up Firefox the way I want it (the biggest ask has always been getting a bookmark to open in a new tab). Two days in, sometimes a bookmark opens in a new tab, and sometimes it doesn't. I have nothing else set up except for an ad blocker. I have not changed my OS from Sequoia to Tahoe yet, I strategically delay. It's not the end of the world. But I had strange things happen with Firefox on my other mini (an M2) in the last 6 months and I had to abandon Firefox and use Safari, which I hate. But that's a whole other topic. I've used Firefox forever, and it's my fave, and little things like this bug me. What am I missing? I set the option to False, and then reset it to True, and sometimes it works as it's supposed to, and sometimes it doesn't. So to not overwrite an open tab that has something important, I just automatically click on the 'command' key when selecting the bookmark. It's staying on my selection to 'true' and I've set it to false and then set it back to true, and restart Firefox, and I still get inconsistent results. There's nothing else that could be conflicting with this. I don't get it. Like I say, Firefox on my other mini just totally became unreliable and I had to use Safari. Any ideas? Thanks!

Before the update, I could use "cmd+shift+[number]" to open a new container tab. Now, nothing works. "cmd+t" opens a tab with "no container", which is completely different.

I already tried going to "about:keyboard", but opening a new container tab isn't even listed as an option.

Hello.

1. How to save a tab group without closing it? 2. How to make individual tabs in a tab group permanent? (So when you close a tab group only the permanent members are preserved.)

I used Firefox a few years ago, and I'm using the latest Firefox for days. Sometimes inactive tabs are auto-closed. How can I disable the feature or where can I check the URLs for closed tabs?

I love Firefox and generally really appreciate the way y'all operate as a company and developer.

However, I really don't like this new function to add tabs to a group. Since it rolled out, I'm always adding tabs into groups when I don't mean to. Really, it's creating a group almost every time I move a tab around. If I delete the group, it's just more clicks and distractions to deal with.

In the past, when you've rolled out new features like this, you've also made it very easy to turn off any new feature we don't like. But I can't figure out how to turn this off. Is it possible?

Thanks for your help.

My Firefox browser just updated to version 143.0.1. When the browser reopened, there was an instructional page that opened in a new tab describing the Unload Tab function. I followed the instructions, right-clicked on the tab, the drop down menu appeared, but there wasn't an Unload Tab option. However, there was a Reload Tab option shown.

How do I resolve this? I'm using a macOS 15.6.1.
