I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

When I open up the Add-ons Manager it shows Window Titler is turned on. But Ctrl-Alt-T no longer works, there is no button showing for it, and it seems to be gone. A button for it does not appear in Customize Toolbar. It is the single most important reason I stay with Firefox. How do I get it to work again? Thoughts appreciated.

Google suggestion in Firefox's address bar keep showing Japanese suggestions even though I chose English and Canada as language and location with my google account.

I use same google account with google chrome, but google chrome doesn't show Japanese suggestion.

As for setting on Firefox, I unticked other than "show search suggestions".

How do I resolve it?

Thank you.

When loading webpages, it will often take 60-90 seconds to load the page. I've only seen this happen when loading the page for the first time, once it loads navigating through subpages is seamless. It doesn't seem to be tied to any particular domain, I've had it happen randomly on gaming websites, tech websites, even google searches. The most notable coincidence is that in the networking tab of the developer console, it always(?) takes almost exactly 30 seconds on DNS resolution, 30 seconds on Connecting, sometimes a 30s Blocking element, and then the remainder is near instantaneous; screenshot attached. My network is fine, I'm able to play low-latency games without issue, and Chrome is not exhibiting the same behaviour.

Things I've tried to resolve:

• Restarting computer -- issue has been persisting for months
• Created a new Firefox profile -- still showing the same behaviour
• Disabling all addons/testing Troubleshoot Mode
• Proxy settings in Firefox -- No Proxy and System proxy settings are both showing the behaviour
• Disabling DNS over HTTPS

Any help would be greatly appreciated.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

The security sequence for log-in is supply of user-id and then password; that works fine; then a send unique code dialogue pops up and it leads to an error screen which I am attaching. I have rung the number provided and they say they don't support Firefox; so that looks like end of Firefox use to me and goodbye (can't find a tearful emoji to insert).

Gotta say this kind of thing is happening quite frequently for me; mostly without a nice error screen like this one; last one I recall was hunting for car insurance; on the screen where it listed the billions of quotes to eager providers none of the links to click through for the quotes worked... and with this happeneing more frequently now you go... ohh it's firefox again isn't it... so you reluctantly fire up Google Chrome and of course it works OK.

So I'm kinda here with a broader outlook than just this specific problem; I really am on the verge of giving up with Firefox; it should just work shouldn't it; and it increasingly doesn't anymore; I don't want to get into an extended and convoluted dialogue to help you cure this issue; I'm simply perplexed that some really basic stuff doesn't work anymore; however; I've used Firefox for centuries so thought I should give you at least a chance so I could declare how I feel etc.

I am up for a dialogue over this and hoping this is an easy fix; but; as I say; I'm confused as to why, for me, Firefox just simply doesn't work well anymore; it just should and I shouldn't be here.

I want to turn off a recently added search bar icon in the new version of the newest version of firefox ? I only use google and don't have other search functions enabled but i dont like seeing this icon that suddenly appeared without warning ?

It is too distracting.

I tried to do the fix using userChrome.css but it just didn't work. Am I doing something wrong?

Also the fullscreen animation fix using the about:config settings doesn't work either.

Thanks in advance :3

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

It looks like some sites are not working properly, two examples I can give are google sheets&docs, in the attached image you can see my sheets are not being shown, note that if I directly access a sheet's link it does open.

The second example is some websites with media players just load infinitely (YouTube works).

Also added network tab non 200 status code requests images.

Things I've tried:

• Disabled "network.dns.disablePrefetch".
• Tried troubleshoot mode(meaning those requests that were blocked by ublock are not the problem).
• Deleted history including cookies.
• Private Browsing.
• User Agent masking
• Reinstalling

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

Firefox now requires me to use a passkey to log in to YouTube. I don't have (or want) a passkey. My computer locks up solid, and I have to reboot when I cancel the request for a passkey. I can log in to YouTube on my Samsung S10+ tablet and S25 phone without problems. This problem only occurs on my Windows 10 computer. It is impossible to bypass this issue.

Hello all

There was a pop-up on my Mac'S Firefox asking if I allow Firefox access to my local network devices. I clicked on 'No' And obviously now I can't access for example my router's webpage or any other webpage fromo any devices on my local network. How I can switch it back? Internet access is working fine.

Many thanks, Bogdan

After new update (135.0a1) my youtube vids starts with audio but NO actual video. Also it timeline constantly extends (like when you move cursor to timeline is extends verticaly and get more light color) and back to grey state.

I tried remove all addons, clear cookies and private windows. Also previewr of video rly buggy and just spams images(?)

I have a custom pitch black theme ( pls add it without addons ) which now only flashes for a second when i open the browser and returns to the normal greyish dark mode. When i go to Firefox Color addon page and load it again in saved themes it stays pitchblack even if i open another browser window until i close all the browser windows .

It seems from reading on forums and googling that there is a "return receipt" function in Thunderbird. My problem is I can't find it anywhere in my software. I've searched in every category and can't even find an "Options" on the menu. I remember when Thunderbird did have a "return receipt" that was very easy to find. Now it seems that it has disappeared altogether. What gives?

For the past few months, I've been getting this error and been searching for possible solutions. None of which have worked. I am also not using Kaspersky AV. With this, I'm asking if there's anything else I can do.

Here are the solutions I've tried: 1. Troubleshoot mode / disabling add ons 2. New profile 3. Clearing cache / cookies / dns 4. Changing "DNS over HTTPS" & proxy settings 5. Disabling firewall / AV / VPN 6. Chrome loads the site but I do not want to resort to this. Using developer mode browser does not work either for firefox.

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

Not sure why, but Gmail is not loading, then Ebay shows gmail pic broken, and can't log into ebay either. I can log on bot via private window tho I have removed all ad-ons, uninstalled adblock, still no go, this happen with Some of the Firefox updates, but different sites. Thanks

Hi.

Can't access router gateway since last week

Gives error: Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

Gateway is http only, I can access it fine via Edge and Safari iOS

I tried disabling https-only though it used to work fine before with a saved exception.

Made sure Win10 firewall allows Firefox for private/public

Followed the help link and deleted the previous certificate from the certificate manager, but I can't find anything relevant under the servers tab

I'm at a loss. Many thanks in advance.
