Firefox Support Forum

Hello!

I am multilingual and write in multiple different languages, and the red markings from spellcheck underneath non-English sentences get annoying when they are so frequent. I understand that I can install multiple dictionaries, but that does not allow me to use more than one language's spellcheck at a time.

Is it possible to activate 2+ language dictionaries in Firefox?

Thanks for the help, Sylvan

User unable to launch Firefox browser, will just have an cursor loading and no response after that. The issue might be cause by the DLL QIPCAP64.dll from Forcepoint interfering with Mozilla Firefox . This issue occur after firefox auto push to version 102, which is release on 28 june 2022.

I used the same account with two computers. I always keep my account in sync. Actually, they do not. My previous notebook has a series of bookmarks, but the bookmarks in the latter one is exactly different. It seems like two accounts, but I log in with the same account. Miracly, when I log the same account with my phone, the bookmarks in my phone is sync with my previous notebook I don't know how to solve it and appreciate your answer.

我有两台笔记本，登录同一个账户时是不同步的。两个笔记本的书签页完全各顾各，但我登录的是一个账户且一直保持着同步。当我用手机登录同一个账户的时候，手机会有第一个笔记本同步；第二个笔记本就好像完全是新的账户。 我不知道怎么解决这个问题，希望专业的你的回复。

Hello, I have been using Firefox as my main browser for more than a decade. One could say i am some Mozilla fanboy, having convinced many of my friends and relatives to use Firefox instead of any chrome based options (Which there are to many these days). It struck me today, as i was reworking some workflow elements in many programs i use daily, that it is impossible to change any key binding in Firefox anymore. I know it has been a while now, and i searched all over the web for an answer or a solution, but at this point it is clear that other than going in the code and recompiling Firefox manually, it is not possible. I stumbled upon the (only) extension that allows to change some shortcuts, but the two that i wanted to change are impossible to configure from it, being disabling only f12 as i would use it for other things but i do not want to lose the dev console and also ctrl+L to open the address bar, it is quite inconvenient and would much prefer to use ctrl+spacebar as it matches many other bindings i am using with other software. There have been many other features that were changed in the recent years that made me start to look for an alternative, as i see features melting away almost as quickly as the user base of the product.

I do understand that one person's problem is not going to change the way a big piece of software is working, but i am wondering, why are the users losing such features as basic as customizing key bindings in a piece of software that used to be so incredibly customizable in the past? Why is the only viable option to anything chrome based losing it's edge over the competition? Is Firefox v150 be based on the chromium engine or will it die before?

Thank you in advance, and no, i don't need the link to the shortcut page, i already have it.

I have set my privacy settings to block all third-party cookies, but it makes wading through the console annoying when working with my userscripts.

Not only do I not care as practically every site complains about it, but the warning isn't even useful in understanding what has been blocked most of the time. I just end up with a console filled with "Cookie “” has been rejected as third-party." from a bunch of random sources.

Is there some way to suppress these and only these warnings? I want to be able to actually use warnings in my scripts. As of now, I just don't display warnings and use the other logging levels.

Firefox will not allow me to log into Nest home page with google account. When google account is selected at login it will loop back to select which account to log into with. Never had this issue with previous versions of Firefox Have used the open/option to determine that the issue continues to exist. Version 102 Mac laptop

Recently got a new computer with Windows 11, and now whenever I try to play a Youtube video or videos on other sites, Firefox as a whole slows down. There is a delay when starting the video, and at times Firefox stops responding if I try to switch to another tab when this is happening. (Not always, but sometimes).

The delay can be anywhere from 5 to 45 seconds or so, and repeats whenever I pause and unpause a video, or even rewind slightly. This doesn't seem to be buffering, and videos seem to work just fine on Edge. Any idea what could be causing this issue?

Hello, I have a problem with firefox and it's recently unable to open Google and Youtube due to HTTP Strict Transport Security (HSTS) with an error Code : SEC_ERROR_UNKNOWN_ISSUER

I have done the steps in here : https://support.mozilla.org/en-US/kb/error-codes-secure-websites I don't have any third-party Antivirus

I have also do about:config security.enterprise_roots.enabled by changing to true. It works but unfortunately youtube is broken when i set it to true.

I can't also accept the risk and continue since there's no button that says it.

Thank you

Please see the message below recieved on a web site I use daily when i wanted to review some information about my accounts -

406 - Client browser does not accept the MIME type of the requested page. The page you are looking for cannot be opened by your browser because it has a file name extension that your browser does not accept.

On the console log, it is giving a bad gateaway for the post request when I am trying to add photos from the attach option given below. Same issue on mobile app as well.

Whenever I try to open google or search anything, It shows this error and only button to Go Back

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection. What can you do about it?

www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Someone could be trying to impersonate the site and you should not continue.

Websites prove their identity via certificates. Firefox does not trust www.google.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

Firefox was working fine yesterday. But all of a sudden while playing a youtube video it started being choppy. It drops frames, scrolling and video playback are choppy and laggy, there is lag on button inputs, the system is choppy and laggy too while firefox is open, especially when video is playing. I checked the CPU and GPU usage and I can't see any spikes. I have tried refreshing firefox but that did not fix the problem.

OS is manjaro linux (gnome version) latest. Firefox is also at the latest version.

Running Firefox 102.0 in Win 10. When I try to download a PDF file, I get (1) a dialog box saying the download failed, (2) two 0 byte files in the download directory with the name of the PDF file I'm trying to download, and sometimes (3) a PDF file with a filename of 8 random characters that appears to be the file I'm trying to download. How do I fix this?

Since latest version update of Fire Fox, I'm unable to sign into OUTLOOK. I get to the Sign-in Screen, but when I toggle to enter password, page starts to reload login name/password, but page never loads. Tried multiple times in Fire Fox, but launching MS - EDGE I can get logged in and going immediately. Please advise.

Here's where it gets stalled:

I'm unable to access my website through my firefox browser recently. I've communicated with the host company and they can access through all browsers including firefox. Please advise.
