Today a website told me I needed to enable JavaScript in order to continue, despite the fact that it is enabled. At first, when I received this message, I turned off the "NoScript" extension and tried again, but the website still gave me that same message. So then I went to the about:config page. and it showed that JavaScript is enabled because it showed a value of "true". This sort of thing has happened more than once in the past. I'm forced to go to another browser such Microsoft Edge or Chrome, where I do not encounter this problem. Why is this happening in Firefox, and what can I do about it? My operating system is Windows 10 Professional, and if you need any other details, please let me know. I will appreciate your assistance.

I have the HTTP_PROXY, HTTPS_PROXY and FTP_PROXY (and their lowercase counterparts) exported and then the firefox binary is started from the shell script. The settings in firefox say it will 'Use system proxy settings'. Nevertheless I do not see the proxy being used as I can not access the web pages that need the proxy. The 'about:config' also does not show that firefox picked up any proxy related information from the shell environment.

I know the proxy address is correct because if I use brave browser instead of firefox (same shell script that launches brave) I can reach the web pages behind the proxy as expected.

I am running v122.0.1 on a Mac and since the last update if I open a Facebook Messenger message which pops up at the bottom of the screen clicking the minimise or close doesn't do anything and the message stays on screen The only way to get it to close is to log out of Facebook and then log back in again. Is this a bug in this release?

Hello, as of the last week, my Firefox wont open any Excel 365 scripts, pop-up windows are enabled, I have tried with my Firefox account in multiple different Windows 10 PCs - none worked, there is no problem in other browsers.

What could be the reason?

Thank you

Hi there. I use mailjet for sending email newsletters and campaigns. The images that i was uploading into the mailjet templates where displaying fine both on mailjet and when sent to mozilla firefox users.

The problem is that for 10 days now; when i upload images in mailjet and sending newsletters; the images are not displaying in mozilla. In contrast, when i use chrome everything displays fine, both mailjet and email accounts.

I had a long chat history with mailjet support and they requested to follow these instructions to fix this issue first: https://documentation.mailjet.com/hc/en-us/articles/360058211453-Why-are-my-images-not-displayed-missing-in-the-Email-Editor I did this but i had no success so they requested me to use chrome instead of mozilla. But that is not the solution of the problem because this must address all different browser users.

Can you please help me on this?

Thank you,

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

Locking this thread, please continue here: [/questions/1440272]
Signon to GMAIL or Youtube Premium inside Firefox both return an error about using an unsecure browser. No issue with Chrome or Edge.

I have to create a new question because when I try to reply to the answers I received the system comes up with an error page.

My version of Firefox is 120.0.1 and has been downloaded from the Mozilla website.

The problems occurs with all PDF file both local and from the internet.

The attachments are highlighted in blue in t he opened PDF file but cannot be opened. There is no way to click on the attachments.

Attached is a screen shot of one PDF file because I cannot attached the PDF file itself

I AM UNABLE TO LOG ON TO USAA.COM. THE ERROR MESSAGE SAYS "WE ARE UNABLE TO COMPLY WITH YOU RE REQUEST." THE WEB SITE CUSTOMER SERVICE SAYS MY PASSWORD IS CORRECT AND THE SITE IS WORKING. PER THEIR ADVISE ALL HISTORY HAS BEEN DELETED AND THE COMPUTER HAS BEEN RESTARTED. THE SAME PROBLEM EXISTS ON ANOTHER DEVISE CONNECTED TO THE SAME WI-FI. PLEASE HELP. ACCESS TO OTHER SITES IS WORKING. THE SITE IS NOT BLOCKED AS FAR AS I CAN TELL.

As the title states. At least half the time when you try right-click and use the "Copy" function, the option is greyed out. If you try to Ctrl+Shift+C, it opens dev tools! This happens on multiple systems that I have that are based on Debian/Ubuntu. So basically, copy functionality is broken for Firefox Linux users...

When visiting HP.com - US-English site and signing in to my account, it opens fine - in English - but if I click on links, it connects to sites in a different link. I tried it on Microsoft Edge and it worked fine. It's only on Firefox that I have the problem.

I want to disable Norton Safe Search. I followed Inst. Menu, add ons, extension tab, clicked the 3 dots & then delete. Restarted my computer, but it's still there. I definitely need help.

I have Firefox version 100.0 (64-bit) and version 122.0.1 (64-bit) installed somehow. Both versions when you click on Help>About Firefox say they are up to date.

I can uninstall the 122.0.1 version. I cannot uninstall the 100.0 version.

100.0 says it is up to date but in the top right corner there is a box that says: Update available Firefox couldn't update automatically. Download the new version - you won't lose saved information or customizations.

If I tell it to download I get the 122.0.1 version installed separately from the 100.0 version.

How do I get only ONE installation of Firefox?

Hi I'm running into an issue where I'm trying to save files while retaining their original filenames, but '%' characters are changed into an underscore when I try to save it. I've tested this with Google Chrome but it doesn't run into this issue. Is there a setting or workaround so that Firefox will leave the filenames alone?

I use Firefox on a Dell laptop running Windows 10 Pro. Last night, I was was listening to music at my music website (TuneIn) when the music stopped. When I tried to restart the music, I got a message to the effect that my browser no longer allowed me to access a particular station, and a pop-up player showed up to play the music. What happened?

I just wrote this blog post and someone suggested I contact you.

I have my default browser set to Firefox on Linux (Debian Bookworm). When I open an http:// or https:// URL, it opens in Firefox, but when I open a file:/// URL, it opens in Chromium. It seems that file:/// URL makes it resort to the MIME type.

Is there anything Firefox can do here or is this a Debian or freedesktop.org issue?

Thanks!

Hi, the latest update changed what happens when pressing the enter key in dev tools. There's a complete explanation somewhere explaining the motivation, accessibilty and it being more natural/intuitive.

After years using Firefox I can honestly say it isn't as natural as described and the whole process has become very cumbersome. I can understand wanting to provide a more natural experience and give users with accessibility needs a good experience but for me it's not working.

Is there any way to turn the feature off? A setting perhaps?

If not can you tell me which version should I install which doesn't have this updated dev tools UI feature?

Many thanks
