I am developing an extension that will fix YouTube spacebar issue (after recent YouTube update after Alt Tabbing from other window, spacebar is not working to Pause/Play videos).

The problem is that my extension is not working anywhere except on https://www.mozilla.org.

I've already added "*://*.youtube.com/*" to "host_permissions" in my manifest.json file and it's displayed as "Can always read and change data on this site" on YouTube, but it does nothing. On https://www.mozilla.org my extension is activating properly (writes test message in console).

I added my extension on "about:debugging". Can it be related with that? Appreciate any help!

Feature "Reopen previous tabs" are under check, but after closing browser by "X" and reopening it, it'll start load Home page alone. This thing works correctly only by "Exit" button in pop-up menu.

This isn't happened on previous versions before and I want you to make it reopen those tabs again, because I don't feel comfortable closing the browser any other way than "X" window button.

So for starters I am fully aware of the "When you open a link, image or media in a new tab, switch to it immediately" setting, it is turned off.

What I want to do is be able to open new tabs from my bookmarks bar without immediately switching to them. Regardless of middle mouse click or right click and open new tab. Considering the mentioned setting is turned off I would assume that would solve the problem but it hasn't. It has however made it so when I'm browsing or looking through search engine results it doesn't open a new tab right away. But when I have a home/new tab open and am opening tabs from my bookmarks bar, it unfortunately switches to the new tab immediately. I have had this working on a previous install but am stumped as how to replicate.

Any help appreciated, thank you!

This is the first time, that an update lost all of my tabs. Is there a way to access previous sessions, other than the most recent one? I would like to access a session from last week, and see if I can get my tabs back. I'm very unhappy about this and I've not been able to restore my tabs. The current tabs are place holders, and they do the reflect what I had before the update.

For a few days now this thing with the tabs is driving me crazy. When I click on some link a new tab opens, then I click on another link another tab opens. Following some instructions I went to about:config where I was asked to look for neww, then change the default from 3 to 1. That solved the issue with opening multiple tabs, but now when in gmail and I click on a link it remains in the same page and I have to keep getting back to gmail to continue reading my emails.

That was not the behavior before. When I clicked on a link in my email I was taking to a new tab. Which was OK. But then lately every time I click on something it keeps opening new tabs. This is so annoying.

What can I do to go back to the settings I had a week or more ago.

This is FRUSTRATING!!!!

Thanks so much for your help on this matter.

In email when I click on a link

Although I had long ago selected "Open Previous Windows and Tabs" in Start-Up, my windows and tabs were not restored when I inadvertently quit Firefox this morning and restarted. I then went to the three horizontal bar Application Menu > History to look for "restore previous session", but that button was missing.

So I have two questions: 1. Why didn't my selected preference, "open Previous Windows and Tabs " at Start-Up work? Is there a fix? 2. What has happened to my "restore previous session button in the History tab of the Application Menu, upper right of toolbar? Has Firefox deleted the "restore previous session" button? Can I reinstall it in some way?

I'll be grateful for advice. Thank you

Just like the Android version of Firefox does! It opens the new tab(s), but load each tab at visit!

Desktop Firefox also does this at [History / Restore Previous Session]. All the previously opened tabs are opened again, but each of them only loads at visit.

This is I would like to have as default behaviour with newly opened tab(s) in Firefox. > Tab opens. > It hasn't loaded yet! > At visit it loads the content.

PS: I tried, but didn't work: > about:config _ browser.sessionstore.restore*demand (switch) > Addon _ LoadTabOnSelect 3 (But it worked weirdly.)

3 days ago I closed my main Firefox Windowby accident, while other windows were open. To restore, I just used the normal "recently closed windows" option and reopened my windows. Immediatly, all my tabs that were assigned to "Containers" were duplicated, and I lost the "Simple Tab Groups" order. For each tab on a container, a second was created without an assigned container. Fine, i thought, just closed 130 tabs that were unassigned, and moved them to the right Groups again. Next day, i open firefox, same thing. All tabs duplicated (but now on the proper groups). Closed 130 duplicated tabs and moved on. But I can't spend 5 minutes each day doing it! Testing more, I realized that every time I close and reopen Firefox, all the tabs assigned to a Container get a copy. If i close and reopen firefox 10 times, i will get 10 copies of all tabs, with no assigned containers to them, ending up with 1300 unnecessary tabs.

I just cant figure out how to fix it. Any advice?

I know this is most likely a feature, but it's been annoying the hell out of me since I switched from Chrome and I don't know how to disable it. I have looked at multiple (~3) Reddit threads (two of which were archived) which gave me a total of 0 answers, I've looked at other forums, and I've found, get this, nothing. It's so annoying when for whatever reason, my music gets paused and then it's not at the volume I need it to be at, so I turn it up and then almost immediately turn it back down because of the audio fading. All I want is to know how to disable this, PLEASE.

Since the last Firefox update to 108.01, or that is when I first noticed this problem. When I have many tabs open right to the end of the tab bar the new tab + disappears off the screen. The more tabs I open it does correctly automatically reduce the width of the tabs but pushes the + tab off to the right, this never use to happen before it always kept the new tab + in view.

Hello. I have had an issue with new tabs not opening in Firefox for about two days. My browser is updated to the latest version. The best way to describe the issue is like this: every time I boot up the browser, everything will be working fine. Then, within 4-5 minutes, tabs will stop opening. Every time I want to open a new webpage in a new or already existing tab, it will get eternally stuck on the loading stage. However, if I have something like a youtube playlist running in one of the tabs, it will switch from video to video with no problem. If I close the browser and try to open in again, it won't open (although I've already figured out that the latest issue can be solved with an administrator mode). Other browsers are working fine and don't have such issue.

I have tried reloading the browser, reloading the computer, cleaning cache/history/cookies, running the browser without any addons, running the debug mode, reinstalling the browser (twice), running the antivirus check, creating a new firefox profile. Nothing helps. Also, the problem persists in the debug mode - when I open it, the pages load for 3-5 minutes and then the tabs stop opening as well.

Please suggest what can I do to fix this issue.

Whenever I drag a tab to another window in Firefox, the first window will hide all but the most recent tab. The only way to unhide them is to open a new tab. Is there a way to turn this off? I can't figure out what's causing it.

I was downloading Davinci Resolve on a 2021 Lenovo Laptop running Windows whatever it is, and then the software asked to restart. I said NO because I wanted to make sure all my tabs would be safe. I literally am caretaking two parents and had a BUNCH of tabs open for each of their needs and my own. I had maybe 7 browser windows open and each one had several tabs open.

Usually random updates and restarts have NEVER ever lost my browser windows or tabs. But this time? After I said DO NOT RESTART, it did a glitch anyway without restart and lost ALLLLL my tabs!!!!

I could see all the 7 windows at the taskbar but nothing was loaded on them.

For the first time there was no "restore previous session."

YES I tried to do the whole Jason restore of previous sessions, copied a folder onto my desktop, deleted the ones I was told to, and for some reason the new session updated the old session on the desktop and it all failed and now that is gone. My last hope was the ONE file that was not session updated (not "recovery," not "previous") but an "upgrade" file and when I clicked on it, I get the box that went nowhere when I tried the exe file nor save (attached screenshot). Now it has restarted too many times to restore the "previous" session.

Yes I still have my browser history BUT.........

My only hope is going through literally THOUSANDS of website history I still had but one month literally had 4000 sites (I do a lot of research). So many were important but not thousands. I have been perusing each one, one by one but WHICH could have been an OPEN TAB????

Is there ANY easy way to see which of the thousands was actually an OPEN TAB???

Thanks in advance.

I was wondering if I can enable this function (that green text saying "Mozilla Foundation (US)") or it was deleted. If it's still in browser, can someone show me how to enable it?

Hi there ! How can i get this type of Tabs? Is it possible? This is so cool ! (Though dark tab ofcourse :D) Example Image Attached...

Thanks Shaer Alvy

I recently came across this [https://support.mozilla.org/en-US/que.../1276091|question] when searching for a solution to unintentional detaching of tabs. The responses included mention of an addon as well as a new setting added in version 74 that sounded like the perfect solution for me by retaining the ability to detach a tab to a new window if explicitly requested via context menu.

I configured allowTabDetach to "false" but today had a tab unintentionally move to a new window because I clicked on a tab too quickly while the mouse was in motion. I'm not sure if there was a regression in behavior for this setting or if perhaps it does not combine well with the Tree Style Tab extension.
