Firefox Community Forum

I would like to disable automatic session restore completely. When I restart my PC, crashes or anything like that, I do not want Firefox to restore my previously opened tabs or windows. When I open firefox after a system reboot / crash, I want to only open my default home page. Only if I manually click History > Restore Previous Session should firefox ever restore my session, otherwise never restore my sessions.

I tried unchecking Settings > Startup > Open previous windows and tabs, and also tried following this article: https://support.mozilla.org/en-US/questions/1182594

My sessions still restores after my computer restarts or crashes.

Why do I want this? When I reboot my computer, I want a clean slate to start from scratch, not the dozens of pages (and other software) I had open from my previous session.

I am running linux mint btw.

Hi all, I'm using Firefox 140.0.4 (64-bit) on Debian Trixie and I'm getting a weird behavior with the auto-complete functionality of the address bar.

If I type the first character the address gets auto filled (see 20250711_First-character-auto-fill-working.png attachment), then if I type the second character the auto filled result disappears (see 20250711_Second-character-auto-fill-NOT-working.png).

I've tried any search option combination, but results doesn't change. At the moment I'm using for the address bar just "Browsing history" (see 20250711_Address-bar-settings.png).

The correct behavior would be, as in the past, that new characters confirming the address would leave things as they are. Do you have any suggestion on how to restore the original behavior?

Many thanks,

Raoul

我的系统和firefox版本如图, 我的firefox配置 user_pref("browser.download.dir", "/home/thsea/dls"); user_pref("browser.download.folderList", 2); 另外我在.profile 中设置了 XDG_DOWNLOADS_DIR=/home/thsea/dls 然后就遇到了这个问题,只要一打开firefox的setting firefox就会自动在家目录创建Downloads这个默认文件夹 但是我明明已经配置了其他的了啊,我看源码,它是会先检查用户配置,失败才会创建这个默认的啊. 所以我就搞不懂问题出在哪里,只好求助你们

I'm one of those people to whom sub-pixel smoothing just looks like a colored blur. However, there seems to be no way to disable this. Firefox seems to ignore my system settings in this regard. Did I miss something in the settings?

Hello if i enter proxy and ip address in firefox in Manual proxy configuration section then when i open a website its asks for username and password my question is can proxy owner see my data and i am using https websites like post data ?

I am running Mageia 9 and have an HPM277dw printer. The printer seemed to install fine and works perfectly when printing from every application other than Firefox. When I try to print directly from the browser it will leave off some of the top of the page on a single page print or it will print the first page fine and leave off a portion of the top of the rest of the pages on a multiple page document.

I have Firefox configured with auto-expanding vertical tabs. Sometimes, when the mouse cursor leaves the Firefox window through the same border where the tab bar is located, the tab bar expands and stays in that state until the cursor returns to the Firefox window. This is especially annoying with two displays; if the cursor hovers over the tab bar right before moving to the second display, the tab bar remains expanded, overlapping part of the browser content.

When I try to run firefox 141.0 (Linux x64) I get:

libxul.so: undefined symbol: gdk_wayland_device_get_wl_seat Couldn't load XPCOM.

Is there a way to fix this?

I'm using Slackware 14.2.

Hi I recently installed a new webpage in Wordpress. It worked and I got the theme window on my website. I use two browser - Chrome and Fire fox. Now time for me to start installing a new "ready made" theme. It all looked good on Chrome when finished. I opened the same link in Firefox, but Firefox has not changed to the latest theme. https://condorentalpattaya.com I am totally out of clue. Removing cookies and other memory related functions does not work. I do not use Cloudflare. It works on my mobile.

??? Thanks in advance, have a nice day

For a couple of days now Instagram linked videos won't play here. Actually some of them will -- my own reels and anything linked with that button that looks like a movie 'clapper'. But videos that show the triangular arrow pointing to the right, nothing happens when you click. Not sure if this is a FF issue or maybe something changed at Instagram. Did a google search and nothing came up.

For some time now i have had issues with the browser. I get many warnings on Facebook and elsewhere that my browser is not up to date. Even the weather channel does this and now blasts me with ads , as before i had ad blockers and now I do not. I have downloaded both 16 and 32 bit Firefox for Linux several times to no avail.I need simplified help as I am not that tech savvy and it is important to me as i spend much time doing activism , signing petitions and passing on the truth. Thank you in advance

When i connect to vpn and force firefox to use system proxy settings everything is ok. But after disconnecting from vpn, browser just gives error 'proxy server is refusing connections'. It will work again if i set network settings to no proxy or auto detect proxy settings, but then vpn dont change my ip adress. My question is i need to manually change these setting everytime or there is a better solution to this?

I encounter PR_CONNECT_RESET_ERROR when accessing to some websites

mainly github google and stackoverflow

Sometimes "Reload current page" will work, with multiple tries

I am in China and I am using v2ray+v2rayA for accessing foreign websites (it is a necessity)

This issue happen only on firefox, as edge and chrome can access without error

Is there some settings to disable the PR_CONNECT_RESET_ERROR feature?

Pourquoi n'est-il pas possible d'entrer simplement les identifiants, sans les mots de passe, pour une saisie automatique des identifiants (généralement l'adresse e-mail) ?
