I have used Firefox for Windows for many years and have had no problems until recently. I have been unable to print my emails: when I click on the printer icon in the upper right corner of an email nothing happens. I was wondering if there was something in the settings that was causing this problem. Thank you!

hello,when i download my attached files in mailbox(mail.xmvds.com), it can be everytime warnning me ,but i trust this url ,it is my company's office mailbox ,how can it unblock it ,?

I cannot begin to express how frustrating this change is... and I struggle to comprehend why anyone would introduce this by writing it into software, but I'm sure it has something to do with money and profits.

There was a time when you could do a search and get a list of results, and then view a specific listing, and then return to your search page and view another listing. however, those days are evidently gone, as now when you return to your search page, it's slightly different results in a different order. Most are there, but some are missing entirely, and the ones that remain are varied slightly. Whaaaat for!? It is truly a form of torture.

Now in fairness I can't tell if it's the browser (Firefox), or the search engine (Duck Duck Go), because I am unfortunately not a developer. However, whatever is causing it should be fixed out of a sense of social responsibility to the greater good.

If anyone knows why this happens and knows how to fix it, I would be sincerely grateful if you shared the solution.

I have installed firefox in my laptop for years. after latest update, firefox runs just fine only for the 1st time, then after closing the app / restarting the laptop, firefox keep giving error (attached) I have tried to refresh, run troubleshoot mode, uninstall and reinstall again at one point I was able to recreate the issue only after reinstalling firefox 126.0.1 portable version and then syncing to the profile ( run ok for 1st time, then it broke down after closing it) The problem also seems repeatable using firefox 115 protable Now, I tried to reinstall the portable version from scratch, it keeps hitting same error from 1st run

I have also double check the firewall and antivirus to make its not blocking All other browsers works just fine

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

   Compatibility package for ffmpeg to provide versions 55 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

when I sign into Goog/setting/2 step, the page does not show "app passwords." I've turned off my ad-blocker extensions and pop-up blocker on the page. See attached.

How can I check what is being loaded on my computer with my browser Firefox when I start up Firefox. It takes too long for my homepage to load compared to other browsers. Can someone help so I can determine what is being loaded when I start up my browser Firefox? Thank you.

For months, now, whenever I try to post a comment on a Yahoo! News article, it reads: "Your comment has failed to published." This only happens in Firefox. My "Privacy & Security" settings are set to "Standard," my "History" set to "use custom settings for history" with settings "Remember browsing and download history" and "Clear history when Firefox closes." so cookies and cache get cleared then.

Sometimes this works when starting a new session. But I shouldn't have to start another session and lose all of my logins just to post a comment on a Yahoo News article.

Anyone else having this problem? Is there an easy and permanent fix? What are you settings set at?

So I have an issue where I am unable to reorder or detach tabs after having detached one tab. When I start Firefox I am able to reorder my tabs as much as I want, but once I detach one tab both functionalities do not work anymore.

- Firefox version 126.0 on Kubuntu 24.04 - After restarting Firefox I am able to do it again once - After rebooting I am also able to do it again once - The same issue in private window - I have refreshed Firefox through Help -> More troubleshooting information - Disabled all my add-ons - Tried it in Troubleshoot mode

I cannot seem to find a real answer online. Does somebody here have a solution for me :-)?

My Firefox tab keeps crashing on a particular website. Whenever I go to twitch.tv, the site begins to load and then I get the "Gah. Your tab just crashed." screen. I'm only getting this crash on twitch.tv pages, and this issue just started on May 31, 2024. When I try to open a twitch.tv page in Private Mode, the page loads just fine. I've never had a Firefox tab crash prior to this.

I've tried turning off all of my Firefox extensions, but that didn't solve the issue. I also tried opening Firefox in Troubleshooting Mode, but I still got the tab crash. I'm using the latest version of Firefox as of today's date.

Hi,

If I have an unloaded tab on right of the current tab and I close the current one, instead of going to the right tab, which is the unloaded one, it jumps to another tab which I'm not sure has what relation to it, it certainly is not the tab that opened it.

I removed every modified entry of "Browser.tab" in About:Config, installed "Select After Closing Tab", no result.

Thanks

As title- Cannot download for example webm format, but jpg is okay. cannot install any addon, theme or anything. DRM didnt install as well. i was trying reinstall, refreshing browser, rebooting.
