Firefox Support Forum

In the last few days, I have noticed that a number of websites are throwing me SSL_ERROR_NO_CYPHER_OVERLAP errors. Most websites, particularly more modern websites, seem to not have this issue. As some more professional examples, www.twitch.tv and www.dndbeyond.com throw this error. I have tried setting temporarily TLS version fallback limit and min to 0, with no change. I'm not really sure how to go about debugging what cyphers these websites do support and why they are throwing these errors. Any help on where to start would be greatly apprecaited.

I set my browser to use English instead of my local language and I expect sites to use English by default. Now for some reason Gmail showed me a "do you want to leave this page" browser dialogue in language other than English.

Turns out, there's a new(?) option to set alternative interface languages, and I suppose websites can now choose which one to use?

Wow, just noticed, even tooltips on this website aren't in English anymore. This is extremely annoying.

I'd love to remove the alternate language from that list and leave Firefox interface exclusively in English. There is no option to remove the second language, only to move priority (see screenshot).

Searching through about:config with "language" didn't help. The closest relevant result was for the dictionaries. I do not have problems with dictionaries; "alternate" did not bring any relevant results either.

Hi,

I'm trying to configure equipment on my local network. Some of the equipment does NOT support https. Firefox continuously changes the address http://192.168.xxx.xxx to https://192.168.xxx.xxx, and the connection fails!

I have tried the various options in HTTP Only Mode, including entering Exceptions. I have also temporarily changed network.trr.mode from 5 to 1 (and 0), but nothing is working!

What can I do?

Thanking you Pedro

Hello, I'd like some help with a performance issue. Basically, when using the theme "Pixel-Punk" while playing a video, ram usage by the GPU slowly increases. It increases until it reaches 8GB, where Firefox will soft crash, displaying a white screen. Firefox will be reloaded, with the animated banner portion in Firefox usually disabled or flickering on and off. The GPU item in the process manager also disappears and ram usage no longer increases. The slow nature of the problem makes it hard to diagnose but I'm fairly certain it's due to this theme. The problem doesn't appear with it off, or even on, until I start watching a YouTube video, where ram usage will slowly increase. If I disable the theme ram usage stops increasing but doesn't decrease to it's previous state. I've also tried refreshing Firefox but that didn't help. Also, I don't have an option for hardware acceleration so I can't troubleshoot that option. I've asked the Firefox subreddit and I was guided to the profiler, but that's a little over my head. Is there a way to fix this? I quite like this theme, and I haven't seen any complaints in the reviews. There are also lots of variables, like the extensions I have, my hardware configuration and such. my hardware for info: laptop - Lenovo Legion 5i Pro Gen 7 (2022) CPU- 12700H RAM- 16GB GPU- 3070ti

Good afternoon,

I've got a problem with add-ons while using Squid MITM Proxy with a custom certificate for Firefox/LibreWolf.

While I'm trying to update / install an extension / theme, it fails with:

``` 1686147276233 addons.xpi WARN Download of https://addons.mozilla.org/firefox/downloads/file/4104397/witchdoctor-2.0.xpi failed: [Exception... "Certificate issuer is not built-in." nsresult: "0x80004004 (NS_ERROR_ABORT)" location: "JS frame :: resource://gre/modules/CertUtils.sys.mjs :: checkCert :: line 177" data: no] Stack trace: checkCert()@resource://gre/modules/CertUtils.sys.mjs:177 onStopRequest()@resource://gre/modules/addons/XPIInstall.jsm:2514 ```

How can I install an add-on while using the MITM proxy?

British Airways enable cookies page, essential cookies greyed out so can't log in. The other three cookie choices are live and ticked. This problem has been here for weeks - can anyone suggest what is wrong?

I know there are ways , with more clicks or longer shortcuts to get to some folders but this is the main and most easily accessible way to get to my bookmarks. I know this has been discussed in some older posts but they are all archived so I can't ask any questions there. Sorting by name, for me, is quite inconvenient as sometimes the bookmarks title isn't immediately, easily remembered. Thanks.

Can you suggest firefox browser settings that might be getting in my way? PNC bank suggested turning off my malwarebytes protection in order to use their site! Not an answer that makes sense to me.

I will also try to contact malwarebytes for their suggestions.

Thanks very much!

I updated. There was then supposed to be a 're-store session'. Didn't happen. And I'm not about to read a thousand pages of twaddle to find out why. Firefox actually just sucks. My tech installed it. I'm going back to Safari.

When using Firefox on OSX (Ventura 13.4) after about 1 day Firefox slows down so much I have to quit the application and restart it. Then it is back to normal speed. I'm not sure if this is an OS-X issue or Firefox issue, but restarting the app fixes it for a few hours, then its incredible slow again.

I can't change the language my websites are being displayed in. I changed every setting to english but websites like instagram and youtube are still showing in croatian (because I live in Croatia). I will attach a couple of pictures to prove it.

We have released a browser add-on that works with apps using NativeMessaging, but it stopped working after updating Firefox to v114 on Windows 10 (64bit). We have confirmed that it works up to v113.0.1. The browser add-on manifest is v2. In the Mac version using the same browser add-on, the application can be linked even after updating to v114. The behavior of the bug on Windows is similar to the behavior when NativeMessagingHosts is not written in the registry. Is there any information about solutions to problems or causes?

Expected results: Launch app via NativeMessaging from browser addon

Hi

Automatic video play has been quite a nuisance in spite of using some recommended measures, such as under Firefox Settings => Privacy and Security => Permissions => Autoplay => both options set to Block Video & Audio and saving. The settings change does not appear to work.

Since I mostly use the Portableapps.com version of Firefox, I suspected it might be the issue, after noting once you restart Firefox, that the settings are both back to = Allow Video & Audio! I immediately checked out a separate standalone Firefox installation which I updated to 114.0 (64-bit), but to my dismay, noticed it does also not keep the preferred "Block Video and Audio" settings, also when the browser is restarted.

So is there a bug in the Windows versions I use on my Win 10 64bit and if not, which would be strange, what is going on, why are the settings not kept and how can effectively stop auto-play, which can be a nuisance.

An example of such videos is on Huffpost, such as https://www.huffpost.com/entry/jake-tapper-brianna-keilar-cnn-gop-race_n_647ece5ce4b0b4444c80b001 where the DeSantis video immediately loads and starts playing. The Settings save does not appear to work at all.

Thank you for you help.

After updating to version 114 I keep having tabs crash. If I close Firefox and reopen it, the first few tabs are fine. After a bit, any tab I try to open gives me a "tab crashed" message. I can only load the default tab screen. If I try to go to Google or anywhere it crashes. I try to do a search and it crashes. I've had to use Chrome to be able to do anything.

Firefox repeatedly crashes when attempting to play video or audio files of whatever type, in every web page.

I.e., just opening a YouTube page without playing the video is fine, but when I click on Play, it instantly crashes.

Here are all the error reports which I stumbled on, and which I submitted:

As this is a known Mozilla Firefox issue this needs to get fixed now!

I can't reset my password. I reset my password for my main email but missed the box that popped up and needed a retry but it wouldn't open up for me again. How can I open that little box to reset my password?
