Diễn đàn hỗ trợ Firefox

Several websites are not loading their content since yesterday. YouTube has a message "Try searching to get started" and even when I open a video, it won't play. X.com is not loading content in the pages. So far it's those two.

My laptop unexpectedly closed Firefox after it crashed and upon a restart I re-opened Firefox, which normally restores all my open windows/tabs from the very last session no problem whenever it force quits due to laptop crashes. But this time when opening, it restored windows/tabs from almost a month ago. I closed Firefox and checked the sessionstore-backups folder: - the recovery-backup files are from the session date I just re-opened with old tabs - the previous.jsonlz4 file is from about a month ago and seems to be the reference point used when restoring tabs rather than my actual last session

Is there any other file or method I could use to recover my actual prior session tabs before it crashed?

I have not re-opened Firefox since quitting the browser after seeing it restored the old tabs.

Thank you in advance!

For past few weeks, Whenever I try to update FFX on windows 11, it fails. It takes me to another screen and tells me to download Firefox. When I try to download it , it aborts with this message.

"download.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site."

To download Firefox with new version I have to use another browser but no choice. Then with new version of Firefox, I have faced the same issue of update and used same approach to update firefox to a newer version.

This error appears for some google sites as well but the same occurring for firefox download site itself is not understood.

I read firefox is dropping linux 32. Are there any alternatives?

I only use the internet to watch youtube videos.

I don't feel like having to buy a new laptop for this.

Mozilla, in their infinite wisdom, sent me a note about something new in firefox, by displaying it in a new instance of Firefox.

It wasn’t until I closed my normal session, that I realised a new instance of firefox was also running, and shut it down on.

In shutting the new instance down after my usual session, it overwrote all my normal tab settings🤬

Q1. Are my normal tab settings recoverable? Q2. Why did Mozilla think it a good idea to open a new instance of Firefox to send me information, rather than simply open a new tab.

NB This is in Windows 11

Is there a fix or workaround?

I've been searching for three days now for a solution that will work to restore my profile from a crashed windows-7 machine to my new windows-11. Nothing listed in any forum or help desk works as described. I used to be able to just rename the folder to the exact file name on the new PC, but windows 11 won't let me do anything. It always needs admin permissions and even after I activated the admin account and assigned a password, I still cannot copy to the folder or rename the folder. Every attempt to do this on W-11 fails. It shouldn't be that hard and I'm tired of wasting days playing with this. I have important bookmarks, passwords etc. I want restored, and I need help. Nobody wants to pick up a phone anymore to assist!

I have never used "sync" because I have multiple PCs and each used for different applications and yes some go back to W-7, the operating system that actually worked well. Each PC has Firefox and a distinct bookmark file.

I went to "about:profiles" and created a new profile thinking I could copy to the new folder, but when i switched profiles I couldn't get back to the original default! HELP!

I have over 100 open tabs spread over 4 Mac desktops. I can no longer access ANY of them after upgrading to macOS Tahoe 26 and installing ESET Cyber Security Pro. I've used ESET with Firefox for many years without ANY problems. But now I have to choose between uninstalling ESET and being unprotected in order to use Firefox AT ALL. Every single webpage is blacked out with the message below. ESET support says that Firefox needs to issue an update to fix this problem.

Firefox had been a safe haven for anti-AI, and used to be my go-to search engine. If this AI bullshit continues, no one will respect or use the browser. Stop implementing AI garbage that steals data

Hi All,

I was using the following CSS to hide the navigation images and show only text labels on the context menu for the Back, Forward, Reload and Bookmark Page menu options...

/* Content Area Context Menu - Navigation Vertical Text */
#context-navigation,
#context-navigation > menuitem{
  flex-direction: column !important;
}

/* hide images */
#context-back image, #context-forward image,
#context-reload image, #context-stop image,
#context-bookmarkpage image{
   display: none !important;
}

/* show text labels */
#context-back:after, #context-forward:after,
#context-reload:after, #context-stop:after,
#context-bookmarkpage:after{
   content: attr(aria-label) !important;
   margin-inline-start: -19px !important; /* this pushes navigation text items to left, aligned with other menu items below */
}

It worked up until a couple of versions ago, but something has changed, and my CSS is now broken, and those navigation icons are back.

My context menu now looks like the attached image below.

Any help with showing only text labels on this menu is appreciated.

Thanks.

For over a week, Firefox always displays the message "Our servers are experiencing problems with our services" when I try to view a TV program on YouTube TV. Opera, Edge and my iPhone do not have this problem. I notice that Firefox doesn't store my location in the same place other browsers do. Could that be the problem?

I hate it when I have to use a different browser.

Hello,

In the latest update I got it made everything into rounded corners. The Tabs and Settings windows as an example. How do I undo that?

I checked thoroughly in the appearance settings and dont see a way to do that. I specifically switched my entire world over to Firefox to get out of the rounded corner UI world only in time for this switch to happen. How do i undo it?

I have been an avid (make that RABID) Firefox user and advocate for more than a decade. I recently had to wipe my hard drive and am still going through the painful process of putting things back the way I like them.

Firefox is (was?) my preferred and default browser. I use other browsers only when forced to for work or when Firefox doesn't function with certain apps.

Now, the new version of Firefox does not allow me to set my own home page. I have a choice of Firefox or blank for new tabs. Yes, I can click on the Home icon to get to my preferred home page... but that's another step. Why?

It's only one day in, but honestly, I'm seriously thinking about moving to another browser that doesn't require me to MANUALLY click a home icon to get where I want. WTF?

Whatever you say, you've made it super difficult for this loyal user.

Tried four times in a row. Had the problem In 142.01. Updated to 143.01. No help.

First image is after the update attempt. I intentionally chose not to update 3 of them

Second image after relaunch.

Firefox used to save unknown files according to the save files setting. i.e. ask where to save files. Now if opens unknown files as text in a new tab.

How can the correct behavior be restored?

Alternately, can the Linux snap be fixed to allow saving of new file types? {The procedure shown in https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file is not present in the firefox 141 snap.
