Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

I am having problems with your Firefox web browser a lot of websites seem to keep crashing and refuse to load and sometimes i am getting errors like this:

https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect

I have checked all settings everything is correct and my web browser is up to date!

I am particularly having this problem on my windows 7 laptop it is a 64bit version.

Any help would on this would be highly appreciated!

Kind Regards

Hello. It seems that Google has created a way of "dealing with" Firefox's automatic removal of the page seeking one's acceptance or rejection of cookies. Each time I refresh the page, the accept/reject cookies pop-up briefly flicks on-screen but then disappears and one is back at the consent page:

https://consent.google.com/m?continue=https://maps.google.com/maps&gl=GB&m=0&pc=m&uxe=eomtm&cm=2&hl=en&src=1

So as things are, I cannot access the consent page to either reject or accept the cookies, and therefore I cannot get past the consent page and into googlemaps.

Google may be aware of Firefox's way of "dealing with" the consent page and has found a way of making it impossible for people to proceed to use of the googlemaps website.

For the last couple of months I have been getting frequent (not always) hangs on exiting Firefox. Sometimes get the windows message of not enough threads. Sometimes goes to "Firefox is not responding". Always have to reboot to clear.

Hi all:

If a paste a URL and press enter, sometimes the Enter key does nothing. I have to choose option "Paste and Go" instead. It is annoying.

This does not happen always, only sometimes. I haven't been able to reproduce it on demand.

I am using Ubuntu MATE 22.04.3 . I have been using Firefox for many years, and I have never had this issue until many months ago, when it started.

The theme is "Light" from Mozilla.

The only extension I have installed is uBlock Origin.

I have seen other users complaining about a similar problem, like for example:

https://support.mozilla.org/en-US/questions/1208635

Therefore, I am guessing that something is iffy in this area. Is there anything I could do to pin-point this issue? For example, I could enable some option to increase console output.

Thanks in advance,

For years we have been able to login to two different websites running on different ports on the same host with our Firefox browser (The last working version was 102.14.0-3.el7_9) our RHEL 7.x system. When I accessed the different sites, there was two Authentication Decisions, one sending one cert (We will call it CertA) to the system and the other listing sending a different cert (We will call that CertB) to the system, same hostname though.

I updated the Firefox browser to 115.7.0-1.el7_9 and ever since, when I navigate to the first website, it remembers the first Authentication Decision to send CertA to the system and works as intended. Then, I try to navigate to the second site and I never get prompted to pick a cert for the second site (CertB is what it should prompt for) and the connection attempt fails with a "Secure Connection Failed, Error code: SSL_ERROR_UNKNOWN_CA_ALERT" message.

If I go and delete the Authentication Decision for CertA, then go to the CertB site, I get prompted for the cert decision and I am able to login just fine. But, then if I try to go to the CertA site, I get the same error listed above.

I can use a band aid to check the "History > Always use private browsing mode" checkbox (Which never remembers the Auth. Decision) option in Firefox, then have to remember to close the browser each time I want to navigate from one site to the next. But I have never had to do that in the past and wondering if this is a new bug or if it is somehow considered a "Security Feature" or something.

I searched around the net a bit and couldn't find a way to manually add an Authentication Decision myself. Is that possible somehow with a config file edit on our Linux system somewhere?

Thanks kindly ahead of time for any consideration to my issue.

Hello,

In Windows 10 and 11, Firefox's tab bar and other elements that may be transparent render in Windows 10 using some sort of uDWM method (speculation, I could be wrong?) rather than the traditional win32 window frame as you can see with the title bar toggled on. This leads to elements like the tab bar being black or white, depending on your theme unless you have specified otherwise in your chrome. Highlighted yellow below is my problem area.

In my CSS code, I am trying to extend the system color to be drawn to the tab bar (and in this instance, the address bar as well,) but I can't find any way to be able to do this. I have found forums that say to add -moz:appearance -moz-windows-glass, but this completely removes the window border and leaves the Firefox window unresponsive to controls. The only way to close it is if you close it through the taskbar or task manager.

Note that I am aware of .titlebar-color{color: AccentColorText; background-color: AccentColor}, but that's not what I am going for here. That still draws using Windows 10 modern UI. Windows 7 on ESR 115 or unofficially on 116 still draw with Windows Aero in all parts of this CSS code that are black (highligted yellow below.)

I can attach my CSS code if need be.

Thanks for any help!

I'm using a Hotspot provided by Cisco in a library and when first connecting to the Wireless network, Firefox prompts me to login to network in order to have Internet access (expected and works fine). However, once the time session expires Firefox will sometimes prompt again to login. When this fails and internet access is abruptly ended, I've to reconnect to the Wireless network and have Firefox prompt to login.

This is a security vulnerability as someone could advertise the BSSID of the router and have victims connect to their Hotspot instead of the true one.

I cannot browse using firefox and Safari on my MacBook Air for the last 3 days. Message saying "Warning potential security risk ahead" I have cleared cache, dont know what else to do

I am using FF 115.7.0 on a Mac. I normally use tabs but when I need a new window, it opens with every one of my bookmarks in a tab. I can open a subject in a new window from an article in a tab from a different window but I just can't open an empty window without getting all of my bookmarks opened in (many!) separate tabs.

Thanks for any help.

For the longest time (can't pinpoint when it started) I've been having issues with Firefox on desktop (Macbook) playing videos and occasionally audio. Video playback will be functioning fine, then there seems to be a "trigger"...For ex. I have noticed this is often me trying to play a Twitter video, which won't play normally, and suddenly NO video playback of any kind (and sometimes audio) will work...Youtube, Netflix, you name it.

The only thing that "fixes" the issue (until it pops up again the next time) is quitting Firefox and starting it back up again, usually clearing my cache first for good measure. I have tried disabling all extensions and it has no effect. I have tried playing the video in a private window/incognito—no effect. If I open up Chrome and try to play the same videos I have absolutely no issues.

My Firefox says it is currently up to date, though I am running an older version iOS (Mojave). I have googled and seen many other people having this issue but haven't seen anyone chime in with a fix that actually works. Any ideas?

Hello,

Firefox YouTube HDR mode works in Full Screen Mode (FSM), Picture in Picture (PiP), but not in normal Windowed mode (WiM). This bug appeared in around Q3-Q4 2023, before that the YouTube HDR mode was available in FSM, PiP and WiM mode.

In Safari the YouTube HDR content works in FSM, PiP and WiM mode.

How do I put bar between tabs, or, each tab inside an individual box ? I have tried many codes from various forums, but since this update, FF seems to ignore ./chrome/userChrome.css completely.

This morning I received an email stating: If you are running a version of Firefox equal to or older than Firefox 78 (general release or ESR) and you have a Mozilla account, you must follow these steps to ensure continued operation of your account in Firefox: I have firefox 115.7.0esr (64-bit) running on a mid 2010 macBookPro with High Sierra OS 10.13.6

My question: what does this mean? Is my FF equal or older? And is a Mozilla account the same as a FF account? PLEASE help me, by explaining exactly what I'm supposed to do and HOW and reply in simple comprehensible language, I am NOT a tech/nerd/geek and already following all these numbers has given me a headache! Thanks in advance.

Om Macos 12.7.3 Monterey using FF 115.7.0esr (64-bit). Been using FF since God knows when. All well. But a couple of months ago windows or tabs are crashing. When I'm hitting a link and either holding Cmnd or right click "open in new tab" in order to get the linked page in new tab, the tab/window I'm using shuts down. Poof.

I prefer to open pdf files with the default viewer in the operating system, not on a firefox browser tab. I have gone into settings->general->applications and configured selected "Use system default application" for PDF files. If I click on a pdf file it downloads to my Downloads folder, which is the usual and preferred behaviour. If I click the downloaded files icon on firefox's toolbar, I see the file I downloaded, all good. If I open the folder with all downloaded files, and click on the file, it opens in the OS's default viewer, all good. On the other hand, if I click on the downloaded files icon on firefox's toolbar and simply select the downloaded file from the displayed list, it opens on a firefox browser tab. This is driving me bananas. How do I configure firefox to launch the default system application instead?
