Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

I recently downloaded Firefox on my Android device. It's been fine. However today, there was an issue. I have the settings set on my phone so bookmarks appear on the homepage. However, today, for some reason, the bookmark on the homepage was glitched. I'm not sure why, but I figured I just had to reset it. So I go rid of the bookmark on the homepage, and redid the bookmark. It was working again, but now, the bookmark isn't appearing on the homepage anymore. It's just a blank homepage, even though my settings are still the same. I've turned the settings on and off, reset fire fox, cleared cache, and the bookmark still isn't showing up. Pleas help me.

I GOT TIRED OF FREQUENT FIREFOX CRASHES (C0000005) IN BOTH THE 64-BIT AND 32-BIT DESKTOP VERSIONS. I HAVE BEEN USING THE 64-BIT VERSION IN WINDOWS 11 (I HAVE A HIGH-END SAGER LAPTOP WITH 32GB RAM. I INSTALLED THE FREQUENT FIREFOX UPDATES BUT THE PROBLEN PERSISTED EVER SINCE VERSIONS 42X WERE RELEASED. I TRIED THE 32-BIT VERSION BUT THE PROBLEM PERSISTED. FINALLED, I TRIED THE DEVELOPER VERSION: NO MORE CRASHES! I READ THE RESPONSES FROM YOUR CLUELESS STAFF TO OTHER CUSTOMERS WITH THE SAME TROUBLE. THIS IS NOT A WINDOWS ERROR; THIS IS A FIREFOX APPLICATION ERROR. MAYBE SOME OF YOUR FIREFOX DEVELOPER CODERS SHOULD ASSIST THE 32-BIT AND 64-BIT DEVELOPERS. OR, DUMP THE VERSION 4X CODE AND BUILD ON THE MORE STABLE 39X CODE. ALSO, DON'T BLAME WINDOWS FOR FIREFOX APPLICATION ERRORS. AND...NEVER SUGGEST A WINDOWS REINSTALL FOR FIREFOX ERRORS!!!

I'm a beta update channel user, so this may not reflect what 'normal' users are seeing. I use Firefox in Linux, debian v13, so normal people that are using Windows or MacOS also might not see the changes I'm asking about? -- I have no way of knowing.

Anyway: in FF v152.0b6, the "Connection Settings" area seems to have disappeared entirely from the settings menu. I used this area of the settings frequently.

The ability to set proxy still exists in the about:config settings area. In the future, will about:config be the standard place to go for people that want to manually set (or toggle) an http/https proxy?

Thanks for reading, and thanks to all the Volunteers who make this place and Mozilla software function. I use your stuff all day, every day, and my life is better because of it.

Since version 148.0b2 (64-bit), it's once again not possible to enter search terms in the search box of a new tab; instead, the browser searches in the address bar. I've had all the settings I found in the forums configured correctly for over five years, and they haven't changed. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Despite this, the search still occurs in the address bar. Now I'm back to the awful search in the address bar. How can I fix this? Please fix this bug as soon as possible.

Original: Set der Version 148.0b2 (64-Bit) ist es wieder nicht möglich die Suche im neuen Tap, im Suchfenster einzugeben, sonder es wird wieder im Adressfeld gesucht. Ich habe alle Einstellungen, die ich in den Foren gefunden habe schon über 5 Jahre so eingestelle, sie sind auch nicht geändert. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Trotzdem wird die Suche im Adressfeld geführt.

Jetzt geht es aber wieder mit der Schrecklichen suchen in der Adresszeile los. Wie kann ich dies ändern? Bitte diesen Fehler (Bug) schnellst möglich beheben.

• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

Hello,

After updating to,

150.0 (Build #2016155439), 1a6c5c6f11fca486436075d92fd82d51f706c775 GV: 150.0-20260415192539 AS: 150.0.1 OS: Android 15

I have been having issues with the address on top of my phone (Motorola Edge 50 Neo).

As you can see, as soon as I switch from Private Browsing to Normal Browsing, the address bar on the top shifts and never goes back to its original position.

It only resets back to its position when I close the App and open Firefox again but the issue persists whenever I try to switch from Private browsing to Normal browsing (vice-versa).

Web pages that are supposed to contain emojis are blank. I can highlight where emojis are supposed to be shown but the actual images of the emojis aren't there. about:config font.name-list.emoji correctly contains "Apple Color Emoji" If it is relevant, this has been a bug/issue that has persisted for a couple of months now (can't name an exact date).

I had about 20 tabs in my "Inactive tabs" on Firefox mobile. Today I wanted to open one of them, but all gone. I can't even found them in "recently closed tabs". This is very upsetting because some of them was very important for me.

Since this week's update of Firefox Developer edition when the browser is restarted tabs do not load until I reset the browser.

I suspect an add-on but have not been able to determine which one.

This is happening on multiple (3) physical computers.

I just started a new work role and haven't been able to find the time to troubleshooting of the issue myself.

This has been very disrupting and stressful.

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

my extensions got unpinned and the new tab button is gone, the tab overview is gone, the extension button is to the left of the address bar, the back and forward buttons are to the left of the address bar, the back and forward button are swapped, WHY.

In the screenshot i pinned the 3 extesions i use again, they were unpinned before

Problems since Thunderbird updated (automatically?) to beta version (63.0). Unable to send from one of my two companies' accounts, despite having been in ongoing communication with their tech support (STARTMAIL) that my settings are correct. They were correct. But now "Account Settings" are not visible (just a tiny non-functional window) unless I got to Help > Troubleshooting Information where they are merely viewable (see below).

Finally, I uninstalled Thunderbird via control panel on my Windows OS. Then I downloaded (from Mozilla website) Thunderbird version 60.2.1.

It opened with the same issues--unable to send via one account; unable to view under "account settings" the details for any of my accounts. Verified with my optimization software (System Mechanic) that 60.2.1 was the only visibly remaining Thunderbird artifact. Did hard shutdown of computer. No change upon re-starting computer.

I had expected that uninstalling and downloading the prior version of Thunderbird would mean that I would have to go through registering in Thunderbird my various email accounts. I thought that I could do this cleanly (all w. IMAP) & more efficiently (no duplicates or leftovers--seven accts on 1 server; one acct on other server). However, Thunderbird opened already populated exactly as I had it (even open tabs) prior to uninstalling.

The only tweaking I have done this week since Thunderbird updated to beta version were: re-set my Master Password... attempt to change the accounts on one server (my ISP's) from POP3 to IMAP (which doesn't appear to have stuck as IMAP, despite speaking to their tech support), but those accounts appear to be working... deleting and re-instating 3x my email accounts with the other server (which is IMAP) due to the problem of not being able to send email's (I have been in ongoing contact with their tech support)--each time applying the new password provided by my server.

BTW, earlier in this process I contacted my antivirus tech support. And I've tried sending with my antivirusware shut off, but login to the server still failed.

Help, please!

We're exploring adopting a default deny policy for Firefox extensions in our enterprise. However when I tested this by creating a custom policies.json Firefox unexpectedly removed all extensions for me, including the ones I thought I had allow listed. Here is my policies.json but just keeping in the Facebook Container add-on to illustrate:

{

   "policies": {
       "ExtensionSettings": {
           "*": {
               "blocked_install_message": "Only approved Firefox extensions can be installed, please email your request to itdept@example.org",
               "installation_mode": "blocked",
               "allowed_types": ["theme", "dictionary", "locale"]
           },
           "@contain-facebook.xpi": { "installation_mode": "allowed" }
       }
   }

}

What I would like is to to allow pre-approved extensions (including if they already are installed) and all other types of add-on, but remove and prohibit installation of unapproved extensions.

Can anyone assist, please?

Basically title.

Every time I close the browser and re-open it, the favicons disappear. I use the favicons to navigate to websites on my bookmark toolbar, but they're missing from my regular bookmarks, too.

I found an old thread that appeared similar, and the solution was to take a working copy of the favicons.db file and re-import it if it breaks (while the browser application is closed). However, this did not work.

Any help would be greatly appreciated.
