Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

I'm looking for the best way to integrate idm integration module in Firefox to get all Internet download manager features.

IDMIntegrationModule.com guide provides 2 methods to do that which one should I use:

1. IDM CC for Firefox 2. IDM Integration Module Firefox Add-Ons

Thanks.

Hello!

I found the new "Close Duplicate Tabs" and would like to suggest the following, for improvement for power users.

1) It should be possible to configure an option for what should happen with the duplicate tabs. For example: it should be possible to move all the Duplicate Tabs to a new Window - so I can view all these tabs and compare them (and close them if I want that) Reason: I use a web interface to a database for documentation and sometimes I have more than one tab open with the same article - but the software behind it doesn't notice, it just stores what comes out and so it would happen that an article is accidentally overwritten.

2) According to what criteria are the duplicate tabs compared - can you set options here?

Best wishes! hannes

Hello. Recently I've noticed video quality has been reduced on amazon prime video. I get a message saying my hardware doesn't meet HDCP requirements.

I've already tried playing the same video on edge, and the quality selector was fine there, full HD video.

Thank you in advance

I'd like to add Firefox to Adobe Dreamweaver for site design viewing. When searching Windows for Firefox.exe I don't see it in Program Files or Program Files (x86). Firefox is installed and used daily. Can someone tell me where it's located in Windows 10?

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

When I am browsing in either regular mode or safe mode, the scroll buttons for next or previous slide do not appear on the MSN web page. However, if I open a private browsing tab from either regular or safe mode, the scroll buttons appear and are functional. I am running Firefox version 129.0.2 (64 bit) on Windows 11 Home version 23H2. I have refreshed Firefox and also uninstalled and reinstalled Firefox. I have also toggled "always show scrollbars" on in Windows settings. No change. These scroll buttons function in other browsers (Edge, Chrome), but I prefer Firefox. Where do I go from here?

Edit bookmark box won't scroll or show me all my folders/subfolders: When are you going to fix this problem: https://support.mozilla.org/en-US/questions/968861

This used to work fine. I don't want to mess with userChrome.css to get it to work. It should just work like it used to.

Thanks very much...

Similar to the issue described in this thread (https://support.mozilla.org/bm/questions/1240674), I am unable to open Firefox - it simply refuses to open. I've tried multiple times, the option key, and re-installing. Nothing seems to work, which suggests something about my user settings is the issue, but a) I am not keen on deleting this if possible and b) I won't delete my user settings unless that is necessary. Like the attached thread, I am happy to attach crash reports, but without the ability to even open Firefox properly it's not obvious how I do this - force-quitting it just sends a report to Apple.

Any help much appreciated - I'd quite like Firefox working again.

My laptop is a MacBook Pro 13 2020 (Intel) running macOS Monterey (12.7.4). I installed the version of Firefox available for download as of writing (v127.0 based on Finder).

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

On several site there's a greyed out box top right, which disables anything it covers, can't be got rid of, and makes using Firefox for these sites impossible. Help, please?? Thank you! (I'm having to use Chrome...)

'DO i need to restart Firefox to get old search log-ins to pop up after making Fire fox my default browser?

Sync is a nightmare. It is so unintuitive! What exactly would be wrong with having separate Export and Import buttons for each of Settings, Addons, Tabs, History, Bookmarks, etc? I have a desktop box and a newer laptop I wanted to get up to date. I pressed the Sync button on the desktop ... By the way, there`s a link below that reads "Connect another device" ... Connect where? Someone is designing these interfaces who has absolutely zero imagination. Anyways, I signed off, moved the ethernet cable to my laptop, signed in, pressed Sync, and voila!, I got my Bookmarks, at least. But I have no idea how to get my tabs and windows. I tried with a "download link" something or other, but it seemed to assume I was sync-ing to a phone, and didn`t work. Any way to get my tabs?
