Issue: Rapidly scrolling up or down often creates an unintended blank space (margin) at the top or bottom of the tab list.

Symptom: When this gap appears, the mouse cursor's focus becomes misaligned with the actual tab selection point by the height of that gap.

Behavior: Scrolling back toward the gap usually forces it to disappear, which also restores the correct alignment between the cursor and the selection point.

Reproducibility: The exact trigger is inconsistent. While it happens most often during fast scrolling, it sometimes occurs during slow scrolls as well. The frequency is unpredictable—sometimes occurring every time, and other times once in five attempts.

I just lost ALL my open tabs AGAIN!!! This's the 3rd time !!!!! Restore previous tabs IS NOT IN THE Menu > History AGAIN per Mozilla's method!! Frankly, I'm tired & overwrought this keeps happening WHEN IT'S NOT SUPPOSED TO!!

Now what cor-el?? I certainly hope you've a corrective answer. dCβ (;>{

Device: Poco X3 Pro System Information: RAM: 6 GB + 5 GB extended RAM Kernel Version: 4.14.18 OS Version: MIUI 14 14.0.6

Issue Description: When I switch away from Firefox Mobile and return after even 1 second, the currently opened webpage refreshes every time.

Actual Behavior: Every time I leave Firefox briefly and come back, the webpage reloads.

Additional Notes: The phone is capable of keeping heavier apps in background. I am able to run PUBG Mobile and Call of Duty: Mobile at the same time without background issues, but Firefox still reloads tabs aggressively.

Troubleshooting Already Done: 1. Disabled battery optimization for Firefox 2. Enabled Firefox as locked app in recent apps 3. Disabled phantom process killer 4. Reinstalled Firefox

I LOVE y'alls new splitscreen feature, BUT I also noticed ya'll put the X on the tabs so that at any time even if unselected, you can close it; Is there any way to make that x appear only when selected because the main reason I used firefox in the past was because middle click was it's own dedicated way to close tabs making selected tabs literally careless and SIGNIFIGANTLY time efficient, but now that that x is on the tab at all times, it gets in the way and IT'S MAKING ME CLOSE ALL MY SPLIT TABS. Please, as a loyal firefox user, with either tell me how to remove the x's or please make it an official option to have them off. Thank you for your time.

Вопрос, думаю, миллиона пользователей: вы когда-нибудь планируете за годы работы сделать так, что бы если ты закрыл основной браузер до закрытия безопасного режима, вкладки в обычном режиме НЕ закрывались?! Сделайте окно проверки, если не можете реализовать, что бы человек прочитал сообщение и НЕ закрыл обычный режим ДО закрытия безопасного? Почему другие то могут?

Open several tabs, in settings, check «ouvrir les fenêtres et onglets précédents», quit firefox.

1. 1. 1. Expected behavior

On startup, Firefox should reopen with the same tabs before shutdown.

1. 1. 1. Actual behavior

Firefox opens with one empty tab. Forcing me to got to «history -> recently closed windows -> restore» everytime I quit Firefox or shutdown the mac.

I use tab groups actively and would save much of my work in my ever-growing list of tab groups. I saw today that many of them had disappeared. I wasn't signed into Firefox and nor do I have any different profiles made. I see two tab groups that I made yesterday but none from before that. How could this happen? How do I recover so much of the work I had saved up?

Earlier tab switcher in Firefox mobile had half screen height which was easily accessible by one hand but now it's on the top of screen which is harder to reach.

At least there should be an option to switch between the two or bring back the old tab switcher and make it go full screen if swiped up and half screen when swiped down.

This one is just killing me reach to the top of screen every time.

dear sir/ mam:

like in safari, i had pinned the websites (as tabs) i visit regularly.

when i restarted the browser, all tabs were gone.

i have been using this feature in safari since a decade and no pinned tabs have been lost.

please guide.

All of a sudden Firefox stopped reloading my previous tabs when I start Firefox (whether or not it is set to open automatically on start up). I have ensured the relevant boxes are ticked and I have even reinstalled Firefox altogether - and all to no avail.

I am using Firefox on a W11 64 bit desktop. I have used it for years and have never had this problem before.

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

Can someone describe to me how you can open multiple tabs from the Browser starting page? All I see is the top search bar which takes me to Google. But what do I do if I wanna do another search in another tab? Most other browsers simply have a clearly visible button to open another tab but I can‘t find it on Firefox Focus. Online it says there‘s supposed to be a + in the top right corner but it isn‘t there on the picture below and it also doesn‘t appear once I do a search.

In Firefox Android, there's an option to automatically close tabs after one day, one week or one month.

I'd like to set it to 1 or 2 hours.

Is it possible? Maybe through about:config menu?

Thanks.
