When using vertical tabs layout with "expand sidebar on hover" setting enabled, sidebar scrolls up with each expansion, so that when hovering over a certain tab of collapsed sidebar, another open tab is under the mouse pointer when expanded. For additional details please refer to the attached video.

Steps to reproduce: 1. Enable vertical tabs layout with "expand sidebar on hover" setting 2. Open a lot of tabs 3. Hover over a certain tab

Observed result: The sidebar expands with mouse over another tab and the list of tabs scrolled up.

Expected result: The sidebar expands and mouse pointer is hovering over the same tab after expansion from collapsed state.

bold text''''bold text' In Settings under Startup, I have check to open all my previous tabs, but when I am shutting down, Firefox wants to close all my tabs before shutting down. If Firefox closes all my tabs on shutdown, then those tabs will not be there next time I start up .... how can I keep my tabs when I shutdown and have them next time I start up

when I click a url link from mail it opens a new firefox window instead of a new tab on existing window. I like to keep all tabs in one open firefox window. Firefox crashed last night and lost all of my tabs; I was able to restore but now having issues with email url links opening in a stand-alone new window - HOW do I revert to former option?

I am using Firefox on a W11 64 desktop. Until recently (the most recent upgrade, I think) all worked well. But since then although the relevant box is ticked in settings (aboutpreferences general), on opening Firefox the tabs from the preceding session are NOT restored. This is extremely inconvenient.

Have any others found this same problem? Any work arounds?

Normally Ctrl+Shift+T reopens the last tab I closed in that specific window, but after the most recent update it reopens the last tab I closed in /any/ window. Is this happening to anyone else?

Hello. I have issue with Firefox. I am often opening firefox by command: firefox --no-remote -P <profil> --new-window "<web_site>" Usualy it works. But sometimes it is opening new window and my web_site is located in second tab. First tab (which is completelly unwated) start loading after clicking on it. It is a recently closed tab. I call this tab zombie-tab. It was finished and properly closed, however it rose from the dead. I tried to set in about:config browser.sessionstore lot of parameter to absolutelly forbid to save any information. However, there is still whole history in the list, sites are restorable and sometimes it appears these zombie-tabs. Restore from crash is also deactivated. I tried before to start the firefox without --no-remote parameter, but AI recommend me to add it there. It did not help. Since it is happening occasionally, I consider it as a bug. Some my settings: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0 browser.sessionstore.resume_from_crash = 0 browser.sessionstore.cleanup.forget_closed_after = 149 Version: 140.7.0esr (64-bita) OS: Debian GNU/Linux 12 (bookworm) How to prevent to create zombie-tabs?

Often after restarting firefox 148.0 … … 

… … for whatever reason, it comes up "clean".   Despite asking for tabs to be restored, they often are not.

I have about 7 tabs that I have pinned (i.e., gmail, penzu, contacts, etc).

Is there a way to have this happen automagically when started?

Doesn't seem obvious to me.

Thanks, FJohn

Hi why have firefox started to close tabs when browser beeing closed? Allready checked the usual sugggestions like open previous, private mode etc. Assuming this relates to an update because have same issue on several computers ( same account)

Добрый день. Проблема наблюдается примерно около полугода. В браузере открыто несколько вкладок, не закрываются (новости, ВК, поиск, различные статьи и тд.). Происходит следующее: читаю активную вкладку, строго через определенное время, без каких-либо действий с моей стороны, активная вкладка меняется, т.е. открыты вкладки 1-5, активная 2, через 10 мин (до переустановки мозиллы всегда одно время) активной становится 4, к примеру. Раньше фокус перемещался на вкладку поиска Yandex, если закрыть вкладку с Яндексом проблема уходила! Я удалил браузер Yandex и все что было от него (автозагрузку, планировщик заданий), переустановил Firefox. Какое-то время все работает, но потом начинается снова, тут время переключения меняется. В последний раз (после удаления Яндекса) фокус стал переключаться на mail.ru, значит яндекс тут не при чем. Если закрыть Mail проблемы нет, если открыть страницу снова, то примерно через 1 мин. открывается mail.ru. Доп. информация Windows 11, плагинов и расширений в мозилле нет, пробовал работать в безопасном режиме браузера - не помогает, перезагрузка не помогает, помогает только закрытие "маркированных" страниц, проверял на вирусы NOD32, cureIT в безопасном режиме работы ОС, вирусов нет. Очень прошу помочь с решением!
