All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

Lest update to 15.9 all my extensions are now disabled. Missing Lastpass and Surfshark from my menu bar. Doesn't seem to be any way to Enable them from Extensions screen.

I reloaded Lastpass from their site and this is now working on my Menu bar.

But what happened to cause this

i had a problem with my java on my windows 7-- 64 bit computer i put a a 64 bit java and put in the websites URL THE SECURITY ON THE JAVA problem was set on low when i go to the web site ( k3fef sdr the web site tell me i do not have the JAVA program and will not open up any ideas thank you gregory oidar7295@optimum.net

115.8.0esr (64-bit)

This newest release has a massive memory leak. I know it's Firefox, because I look at the system monitor, and there are even more entries for firefox.com running than usual. The first one on the top of the list is the biggest resource hog, and the next one is second. All the rest have something going on, but smaller. Looking at performance in the Windows Task Manager, under performance, the memory usage goes up. Right now, it's 5.35Gb of 16Gb. At worst, several days ago, it was at 12Gb. When I force close Firefox, the memory and usage goes way, way down, to a usable level.

I wrote last night. "Ed" someone got back to me, didn't quote my message, and said he was from another department. I DID EXACTLY THE SAME THING AS LAST NIGHT. I hit the blue button, which took me here, and he advised me to do today, which brought me here, AGAIN.

If this, again, goes to "restoring access to Mozilla accounts and subscription services such as Mozilla VPN", please be professional and forward it to the right department, possibly with my message quoted, as this is the second time I'm creating it, and only have my memory on which to fall back for the first time. The logical topic is "Fix slowness, crashing, error messages, and other problems".

At the same time, other releases have had big memory leaks, and they seem to get patched quickly.

Thank you again.

Hello. I suspect there was a cyber attack on April 1 2024. All of a sudden,having problems crashing with more than 1 browser. My Brave browser would open,and then crash with multiple tabs that had been saved. My Mozilla history was cleared,and I want it back because I need to find all sites I have visited from time to time for logins etc,but they are now gone.I have tried importing all of my Brave history,login forms to Firefox,but not sure where to located them or where they would be stored.

Right now i am focused on getting a Firefox profile from before April 1

I have never had to deal with this sort of thing before so i am saying that i may be somewhat noobish on this.I just want some expert instruction on what to do here,and how to do it.I,m not 100 percent sure if i can do it correctly on my own by googling this myself,then attempting it.Brave continues to open then crash right after,so I dont know whats going on there with the userdata folder in the appdata folders with regard to Brave. Everytime i try to install an older version of Brave,it says i already have a curent version of it,and i dont want to uninstall brave then reinstall it again,or not sure if i should do this. ThankYou.

Using YouTube for example...

Previously, when I bookmarked a page/video (URL), if the newly bookmarked page (URL) had previously been visited, the bookmark would be displayed in the Sidebar (or Toolbar) with a typical "YouTube Play Button" icon (favicon). But, if the newly bookmarked page (URL) has never been visited, then the bookmark would be displayed in the Sidebar (or Toolbar) with a default "Globe" icon (favicon).

I almost always create bookmarks by dragging links/URLs from the browser client area to a folder in the bookmarks list in the sidebar (and sometimes/rarely, to a folder on the Bookmarks Toolbar). But the same happens if I manually create a new bookmark to a "Visited" or "Un-visited" page.

Recently, this behavior just changed "without notice"...

Now, when I drag a link/URL from a the "Recommended videos column" on the right side of a YouTube page/video, to the bookmarks list in the sidebar, the bookmark is ALWAYS displayed in the Sidebar (or Toolbar) with a typical "YouTube Play Button" icon (favicon), regardless of whether the page had previously been visited, or not. Also, existing bookmarks for un-visited pages that were previously created, and were previously displayed in the Sidebar (or Toolbar) with a default "Globe" icon (favicon), are now displayed in the Sidebar (or Toolbar) with a typical "YouTube Play Button" icon (favicon).

How can I bring back the previous behavior of displaying bookmarks of un-visited pages/URLs in the Sidebar (or Toolbar) with a default "Globe" icon (favicon)?

Firefox detected a potential security threat and did not continue to noodlemagazine.com because this website requires a secure connection

Hey folks... I am running the latest ESR version for windows 7. I know, its limited support and stuff but I have this most annoying problem that just doesn't seem to want to go away.

Every day, several times a day, I am told there is an update available. I have gone in several times and downloaded and installed the latest release. The install goes fine, there are no issues. Yet, over and over again I am told there is an update... but I have the latest version installed.

In the past, I have used the "distribution" folder trick to stop updates and I have removed that a long time ago. I can't figure out why it keeps telling me there are updates, when there are none.

How can I stop this from doing updates where there are no updates to get? It's driving me nuts...

Dear ladies, dear gentlemen,

on another Computer, when using Firefox, I am now constantly getting a Norton notification of a malicious domain request 22. The problem does NOT arise with the Opera browser installed on the same machine. What shall I do? Uninstall Firefox seems to be the best solution. Scans do not reveal presence of malware. On this computer, similar OP, this does not happen, but I use it much less.

Thanks a lot, Alexander

I noticed that after the recent updates, the pop-up notification for blocked pop-ups has changed from yellow to white.. This makes it very difficult to see and I almost missed it. Is there a way to revert this change using userChrome.css?

I don't understand why this unnecessary change was made. I already have my own userChrome style for the entire Firefox because it was frustrating to constantly change it back after each update.

I would appreciate any information on how to revert this change.

Thanks.

Hello, I am using firefox 83.0 and I don't want to update it (Why? Because I've an old PC with poor hardware and the playback of online videos is lagging/shuttering in releases after 83.0)

BUT firefox 83.0 doesn't support private fields which make some webpages unable to be loaded. the private fields was supported starting in release 90.0 and I'm using 83.0

So, I need a way to make firefox 83.0 support private fields, Is that possible? Is there a certain files should I edited or replaced to make it support private fields?

Any ideas would be appreciated.

I tryed Firefox 115.8.0esr and 115.9.0esr 32Bit on Windows 7. (78.15.0 works) Firefox crashes(the whole program, i mean no tab) on "about:support" or some pages on support.mozilla.org like https://support.mozilla.org/de/kb/firefox-leistungseinstellungen always reproduceable.

I disabled all Addons, i disabled this power optimizion setting, removed usercrome.css same. With Firefox savemode it dont crash. Spyware is blocked, means datareporting/telemetry/ping by disabling the options and empty the urls (like on FF 78 but it dont crash). Somewhere i read firefox can crash on a empty url, but i assume its fixed long time ago. A wrong, unreachable or empty url should not crash on well programming. Think about countrys that blocks urls, adblocker, pihole and so on. I dont remember about what url i read.

Does the savemode revert all about:config settings? What does support.mozilla ask the browser that causes the crash? It know it seems to identify the Browser, but usual its done by useragent and no "internal" communication.

Then FF always crash on ebay.de search if you scroll or change settings while the page is not ready. Spyware is too blocked by Hardware, ebay may wait for some ad? But thats already on FF78 but on 115 it seems more often, this was not with FF 52. But some sites including ebay stops to work with FF52/78 so no choice.

I start Firefox from a batch file (Win7) on the first boot of the day. Manually I choose my "NEWS" bookmarks folder, then slide down to "Open all in tabs". (attached image) (Then I go pour a coffee while the news article tabs open and load data!)

Please and thank you, is there a way to specify this action from the command line? And if so, what is it?

I believe that I could use such a mechanism in other ways, such as opening all tabs in my "Forums" folder of bookmarks, or on Mondays, opening all tabs in my "Weekly" bookmarks folder.

Thank You, Chris

I have used FireFox for years Now I can not download VPN as it requiers W 10+ I can not afford new computer, I am a Disabled Viet Nam Vet/ A MARINE I dd not what all these new apps and maybe Windows is blocking download - HELP

When a new bookmark is created it goes to the end of the bookmark listing in the left panel. How can I force Firefox to automatically put each newly created bookmark in the correct alphabetic position in the left panel Bookmarks panel? I DO NOT want to alphabetize the entire panel, I just want each newly created bookmark to go where is alphabetically belongs. I do not use folders so have one long list for bookmarks menu. thank Bob
