I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

For unfortunate reasons too tedious and mundane to discuss here, I am stuck with Mac/OS 10.11.6. I am looking for a version of Firefox that will run under that version of Mac/OS. I did the basic research and was directed Firefox version 78. After that, I was directed to the Extended Support Release. When I downloaded and ran that, I was directed to the Apple App Store where no version of Firefox could be found. Where to next?

Can someone offer me a link to a version of Firefox that I can download and run on Mac/OS 10.11.6? Please.

I have open half a dozen or so tabs related to one subject. I would like to put them all into one "super tab", such that only the super tab shows as an open tab. Then, by clicking on that tab, it would show the tabs within it, any one or more of which could be selected. Is this possible, and if so how is it done? Perhaps there's an add-on or extension that would do this.

I have already created a multi-tab bookmark that sorta, maybe accomplishes the same thing. But it's not as convenient as what I envision as described above.

Thanks for any advice or words of wisdom.

In the new firefox I cannot find the home button. Where is it? Do not tell me someone decided to remove this most basic of all browser functionality? Are you kidding me? I never thought id ever stop using firefox, but this is what will do it.

Where is the home button pls?

After today's update to version 98 Firefox keeps saving files to the Downloads folder when I don't want it to, I just want to open them, but not keep them, with this new behaviour the Downloads folder keeps filing up with useless clutter.

For example, before the update, when I downloaded a .zip file, a pop-up would show up asking if I wanted to save the file or open it with an application. If I chose to save it it would be saved to the Downloads folder, and if I chose to open it nothing would be saved to the Downloads folder.

After the update, when I download a .zip file, Firefox always saves the file to the Downloads folder, even if I choose to open it.

Can you please tell me if there is a way to make Firefox behave like in the previous version?

I was cleaning out my hard drive and deleting old installs of Microsoft Visual Studio Redistributable packages, and I almost certainly deleted the one that Firefox relies on.

I then attempted to start Firefox, getting the error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem."

I uninstalled, following the clean install directions, and deleting the "Program Files/Mozilla Firefox/" directory.

Then, I ran the Firefox Installer, newly downloaded, and when running it, it gives the same error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." Selecting "Restore Defaults" has no effect either way. The installer then appears to complete in the background, and the Firefox directory is created, along with the executable.

When I run Firefox.exe, it seems to load the program, but any address I type in fails to begin loading. This includes websites (www.google.com) and help/utility pages (about:config). I'm therefore unable to change any settings within Firefox.

I then tried re-installing the "Visual C++ 2008" and "Visual C++ 2015-2019" packages in an attempt to restore that DLL, but that had no effect after repeating the same steps above (clean uninstall, re-install). Which VC++ Redist Package should I be re-installing? Ideally, I should be able to just get a copy of VCRUNTIME140_1.dll and place it where Firefox is looking for it.

Reviewed "Sheribee" earlier issue which apparently involved a VPN. I do not have a VPN but have tried several times in the past week to access IRS refund status site without success. I can get into irs.gov, but am unsuccessful in accessing the refund status site after entering required input data. The issue has occurred only this past week.

I'm unaware of IRS issues causing this problem.

Have not had this issue on any other sites; and I have successful retrieved data in prior years.

I am not saving any sign on protocols with the irs or any other sites.

Running Windows 10. Thanks for any help. BTW I did get refund information using the telephone, but I want to ensure there's not a hidden conflict of some sort with FireFox. Thanks for any help.

Read support article about importing username and password info direct from .CSV file. I see at the bottom of that article that if no such option presents (Import from file), I am to ensure that signon.management.page.fileImport.enabled is set to true. I don't see that operator within the listing of configuration options. I can create that operator and set it to true, but that doesn't make the 'import from file' option appear in the three dot drop down menu within the Logins and Passwords page. Has the title or location of the fileImport operator changed, been moved?

Firefox has been saving images from some sites as webp instead of JPG for a long time. There have been repeated threads on this subject which get locked and then pushed into the long grass.

Sure, I could botch a solution by installing an add-on to convert them, or I could use something like XnView (which I do, periodically, and in bulk) after the save event has happened, or I can edit about:info to tell Firefox not to accept webp - but this breaks functionality for some sites (like eBay), but I have found that in the end I have had to start switching to Microsoft Edge to do my browsing for a number of sites because Mozilla Firefox are ignoring repeated user requests to provide a simple option to STOP doing this.

I don't want to save any files as webp - save them as PNG if you like, or jpg, but I use an ancient copy (v3.24) of ACDsee (from the days of Windows 98) for my image browsing, sorting, viewing etc because it is perfect, blisteringly quick, has no extra editing or other functionality which I don't need or want, and it doesn't bloat up anywhere with thumbnail files... but sadly webp didn't exist back then so it doesn't support it. I have used a number of much more up to date browser-viewers, but there is nothing can touch this OLD version of ACDsee for basically brilliant design.

I'm not changing my image viewer. It's non-negotiable.

I WILL however change my web browser if I have to, if the developers of the browser continually kick into the long grass to lock, hide away and pretend there's isn't an issue which has been repeatedly flagged as an annoyance for so many users.

I have been using one form or other of 'Mozilla' family of browsers since the days of Quarterdeck Mosaic. I don't particularly want to switch my loyalty, especially to Microsoft, but if they are listening to what customers want and providing it, and Mozilla are not, what else is there to do ?

I am a retired systems developer. I cannot envisage this being SUCH a big ask.

Modern software treats its users like idiots and takes away control, doing everything it's assumes on their behalf that they will want.

It is not difficult to provide an option within settings for when saving webp files to save as webp, png or jpg with conversion if necessary. All you need to do is hear the screams and respond. :)

So I was having some trouble a few days ago with a website that automatically re-directed as soon as I landed on it to another page. So I happily went off in the settings and disable the automatic redirect. Now a week or two later I'm sitting here going I can't find the setting anymore? I can't even search for it and have absolutely no results you would think searching for "redirect" in the settings pain would bring it up. it's probably something that got buried in developer tools that I would never be able to turn off/toggle again unless I get lucky with the right extremely memorable and easily accessible incantation in the about : config because that's just all so well documented. Is it a "1" is it a "0" is it a "5" which one disabled / enabled what is the other options do?

I am running "Firefox Browser 93.0", and I have Windows 10 Pro Version 21H1, OS Build 19043.1288. I am unable to watch certain video's, as an example, the video in this link: [https://www.wandtv.com/news/illinois-.../article_24b92a86-32c4-11ec-a487-3bb3f17fa133.html] won't play. It use to work, but something has changed, not by me. It will play that same video using the "Edge Browser" so there is nothing wrong with the website. However, I can play this "YouTube Video": [https://www.youtube.com/watch?v=qAJSYk5wMiA] I also tried another link in their website, this is the weather link: [https://www.wandtv.com/weather] it starts to play, but then stops and nothing ever plays. Here is another link I tried on their website: [https://www.wandtv.com/sports/fans-ma.../article_f94f4ade-32e0-11ec-9351-ef71f52b96cd.html] It won't play either. But they all play in the "Edge Browser!" Any ideas on what changed and how do I change it back, so they will play? I prefer Firefox Browser to any other browser! Do you know what the issue could be? I appreciate your time! NiceSeeingYou

Hello, since migrating from Chrome to Firefox, I have used the Import Wizard to successfully transfer over my bookmarks and history, but I just can't seem to get my logins/passwords over. The wizard finishes saying that it successfully imported saved logins and passwords, but nothing shows up in the password manager. I am running Windows 10 64bit and Firefox is up to date. Anybody have any suggestions?

Thanks

Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.
