Firefox Tekoha Aty

Since Thursday (new update rolled out Wednesday) I have lost all of my open tabs in one window.

Previously, when opening up Firefox, it would reopen my previous window with all tabs.

However now, even with the setting ticked in General (Startup --> Open Previous Windows & Tabs), it no longer does this. I have to go to Menu in the top right, History, recently closed windows, then guess at which window I should reopen.

Will this be fixed in the next update?

I tend to have a lot of tabs open at a time and even with the Customize Sidebar > Hide tabs and sidebar checkbox ticked, it is still distracting at times. Could you please help me find a setting/way so that I can hide it and make it re-appear when I hover on it only. Kinda like how we have on windows taskbar? Much appreciated.

Dear forum, I had to reinstall Firefox and now a tab opens for every request/every time I open a new page. I don't want it to be like this, but only open a new tab upon explicit request. Where can I change this setting? Thank you, Sirpa

As I run my hand up the lid of my lap top, I OFTEN hit the "X" on the browser and the PAGE CLOSES! I am so frustrated because all my tabs close and I see no way to get them all back open. WHY NOT? I know how to use "HISTORY" and under thT i USED TO BE ABLE TO TAP "RECOVER ALL TABS" i DON'T KNOW WHAT BROWSER that was... And if you had that option, I don't know what happened to it.

I have about 50 url’s on my address bar which open every time I login. I delete them one by one but next time they pop up again. I tried using the settings but no help. Any ideas how to stop them popping up when I login? This is something that only happened recently. Never before.

Something changed.

When I clicked a link, it would open in a new window. Now it only opens in a new tap. I need it to open in a new window.

I'm using Win 11 with Fire Fox.

Hi

I don't know which wrong manipulation I have done, but the "+" sign to create new tabs has disappeared.

Could you please help me to get it back ?

(I know that I can right-click and choose "new tab" in the menu, but the "+"sign is definitely more convenient 😅)

Thanks in advance ! :)

Every time I open Firefox, the checkbox next to "Opening links in tabs" always disappears, even though I've checked it in previous sessions. How can I make it permanent?

I use Firefox on the Linux Mint operating system.

I have lots (~100) of tabs open, distributed among windows and virtual desktops. Every now and then the laptop fan starts running wildly, and I identify a CPU hogging webpage in about:processes. How can I now switch to the open window/tab of that webpage to close or unload it? I would expect a click (or context menu item) within about:processes to bring me there. Currently I have to scan through all desktops/windows/tabs to find the page.

I haven't been able to move tabs around for days. Not since I tried to take some 'out' to make a new window, and Firefox straight up crashed ...repeatedly. After I gave up, I noticed the tabs no longer moved.

I ignored it a few days, but its frankly very annoying! I checked for answers & found an old post from 5 yrs ago here & followed the advice. Or I tried to, but when I checked "browser.tabs.allowTabDetach" in "about:config" it was already set to "true". I even toggled it a few times (I even tried to see if it would move when set to false! ...counterintuitive, but I figured it was worth a try?)

Anyhow "browser.tabs.allowTabDetach" is still set to true, and I'm not about to go monkeying with all that :\

(fair warning, while I know how to alter a config under clear instructions ...my experience with such things starts and ends with the config files for Stardew Valley mods)

advice I found, which doesn't work/apply??- https://support.mozilla.org/en-US/questions/1302126

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

I can not seem to find the button to open a saved, closed tab group. I have googled, and there seems to be a lot of people with the same issue. However, None of the information given under those forums provides me with a clear, easy solution. Please help.

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.
