Firefox Community Forum

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

I can no longer log into my social security account using Firefox, but the login does work on edge. When I try login on Firefox, I get the following error message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The initial web site is https://www.ssa.gov/. From there I hit "Sign in", and get to https://secure.ssa.gov/RIL/SiView.action using Edge, but get just the error message using Firefox.

There is another route, which is through https://www.ssa.gov/myaccount/. Hitting either account or sign in on that page will work on Edge, but gives the same error message on Firefox.

I've set up a second profile to keep my personal and work browsing separate. When I reopen my non-default profile, it doesn't restore the previous session's tabs. I have "open previous windows and tabs" checked under Settings > General > startup in both profiles. Please advise.

Recaptcha isn't working in Firefox. It works in Chrome, Opera, and Edge with no issues, it will either just go to a check mark or open the window with the pictures to choose, on both regular pages and on the Google Recaptcha Demo site Google Recaptcha Demo site. But when I load a page that requires Recaptcha in Firefox, it just spins forever. It was working fine a few hours ago, and I didn't change any settings or anything in Firefox. I was filling out a job application and it worked fine, then I went to another job application and Recaptcha won't work at all, even on the Recaptcha Demo site.

I'm on version 125.0.3 (64-bit), on Windows 10. Not using a VPN or anything like that, just a standard Ethernet connection, with whatever Charter gives me.

Steps I've tried, none of which have helped:

1. Cleared Cookies. 2. Restart Browser. 3. Restart Computer. 4. Restart Modem and Router. 5. Opening Firefox in troubleshooting mode. 6. Ensured Firefox was up to date. 7. Reinstalling Firefox. 8. Turned Connection Settings to no proxy. 9. Turned off Enhanced Tracking Protection. (It's set on standard otherwise, and I didn't change it) 10. Release/Renew IP via Command Prompt.

I'm genuinely at a loss of what to do, after a couple of hours of searching around for solutions. I don't get how it just stopped working in the span of like ten minutes when I didn't change any settings or anything. Firefox is my main browser and it would be a tremendous pain to have to use another browser for any pages that require Recaptcha.

Any assistance or advice to solve this problem would be greatly appreciated!

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

Hello guys, so in the past 2-3 days i started facing Cross-Origin Request Blocked for a lot of websites lets take chatgpt for example, if i visit it i get:

Content-Security-Policy warnings 2 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9. (Reason: CORS request did not succeed). Status code: (null). The resource from “https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9” was blocked due to MIME type (“text/plain”) mismatch (X-Content-Type-Options: nosniff).

and its getting so annoying that its blocking a lot of websites, i tried chromium it works fine and works awesomely no cors no problems. I even tried to disable the firefox protection, dns over https on/off, change my main dns upstream, installed firefox developer, compete uninstall/reinstall, cache clear from installers and from firefox it self nothing is working. I will provide firefox developer edition troubleshooting information but keep in mind it doesnt work on both firefox normal and developer

Please any help would be appreciate it.

Firefox v124.0.2-1

Hi.

How come there is no option to turn off "Firefox Translation"? I speak three languages and every time I visit foreign web site, Firefox suggest translation to me. It's annoying.

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

I have not been able to highlight and copy ~ even prior to the most recent update.

Even using control/ does not work.

Really hating this.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to (desktop) Firefox section as you have macOS.

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Error Message: "Could'nt Sign You In: This Browser or APP May not be Sscure 1. Happened to Both Build 124 and 125 2. Virus Clean 3. Haved tried cleaning the cache and cookies

It doesn't matter if I add www.youtube.com site to hosts file in Linux and delete cache, Firefox just doesn't block it, bypassing my meassures to prevent me to get hooked up here. It was blocking everything as expected some weeks ago. I also tried redirecting to different IP's and it didn't work.

After some checks, I noticed:

• It happens only with www.youtube.com, it doesn't happen with youtube.com (without www)
• Other common pages like other Google pages, Facebook, TikTok or Instagram, get succesfuly blocked by hosts file as expected
• I have tested creating new profiles with about:profiles, but the issue continues
• The issue started after Firefox Developer Edition version 125.0b1 as you may notice in the images attached.
• I also tested with the latest nigthly version and the issue continues.
• DNS over HTTP (DOH) doesn't seems to be the problem since it seems that my network doesn't met the requirements to enable it, and if I manually make sure it's disabled, the issue still continues.
• Chromium browser blocks www.youtube.com as expected, so that indicates my PC might be correctly configured

I have:

125.0 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

Video on Facebook plays without sound. The video plays, I see the image normally, but no sound. Video on Youtube works perfectly.

Fresh install without addons or plugins. Switching to "Troubleshoot mode" does not change anything. Youtube with sound, Facebook without sound.

Any ideas where to look?

Firefox can take screenshots of pages or screenshots of custom areas of pages.

According to the documentation, when we download the image, the filename should follow the pattern: Screen Shot yyy-mm-dd at hh.mm.ss.png. If I use the :screenshot at the console, the pattern works as documented.

But Firefox is using a different pattern when I choose Take Screenshot from the context menu. The pattern includes the page's title. Example: Screenshot 2024-04-14 at 18-35-16 General ‹ Settings ‹ Geomaster Lda — WordPress.png.

Since the page title can have non common filename characters, I have problems with such filenames. My uploads to MediaWiki fails with such filenames. I know I can report or improve MediaWiki, but my question here is quite simple.

Can I change the Firefox's default pattern for Take Screenshot's downloads?

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?
