I'm not sure when this started but for some reason I can't play a YouTube video in one tab, then open a video in another tab without Firefox automatically pausing and stopping the video in the tab I switched from. It won't play both at once. I can press play on one then switch tabs and press play then the other stops. I used to be able to play multiple videos in multiple tabs automatically in FF like in any other browser. I can STILL do this in Chrome, Safari, Opera or Edge. If this is a new FF "feature" I want to disable it now.

Video DownloadHelper 7.3.5 no longer detects videos ("No media to process in the current tab.") at several websites where I've downloaded from previously with no problem. So far VDH recognizes only YouTube. I'm using Firefox 65.0.2 (64-bit) (updated today, 3.7.2019). The companion app: VdhCoApp 1.2.4 is installed. It's really disheartening. How do I fix this, please?

Hi,

I like having my local HTML file as a homepage which gives me links to my favourite sites. However, Firefox doesn't seem to support loading a local homepage in a new tab. I have attempted to resolve this by setting up a server and using the My Homepage addon which kind of workds, but it's extremely slow and cumbersome.

Would be very grateful if someone had a better idea.

After I updated to v65.0 (x64), all webpages (except Yahoo) gave me: "Your connection is not secure. This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate."

I read about changing the "security.enterprise_roots.enabled" value to "true" rather than the default "false" and this works, but I am afraid of future consequences.

I am using the following extensions in my Firefox installation: uBlock Origin, Disconnect

Operating system: Windows 7 Javascript enabled: Yes Cookies enabled: Yes Flash version: 32.0.0 Java version: Not installed Websockets supported: Yes Your full user agent string is: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0

I was suddenly getting prompts to update Flash Player. This hadn't happened in months, so I hadn't updated Flash Player in a good while. The first time, I ignored the warning prompt and activated Flash anyway and played the video. This was from tcm.com (Turner Classic Movies). The second time, I decided I'd better update Flash Player, and did so. But now the video wouldn't play at all. There was a locked box icon. I searched on various fixes, looked at a few Mozilla support pages, did a plug-in change starting from the sandwich icon at upper right, same thing. Found another fix idea. Went into the C drive, navigated eventually in Windows to the Macromed and Flash folders, and deleted NPSWF32_9_0_0_169.dll. The red locked box went away. A video played. Next time out, though, back to nothing. In IE, the link will play.

Firefox deletes ALL cookies upon closing, but I have allow cookies for some sites. How can I save JUST the cookies for allowed sites? This used to work in Firefox.

Hi,

I use Firefox and Adobe Flash to play several internet games. Today, one of my laptops (W7Home-64 bit) updated to FF 65.0 and then would no longer play games like Tankionline.com and other Flash games on armorgames.com. I tried System Restore, which worked until the next time I closed and reopened the browser which then automatically updated to 65.0. I played around with it, even copying the Profile directory from another computer, removing/reinstalling both FF and Flash, did not work. Game works fine with MS Internet Explorer. Other laptop and desktop also worked fine. Then, I accidentally closed my browser on my desktop (W7Pro-64) and then when reopened it also automatically updated to 65.0. It now exhibits the same problem, Flash games will not work.

The flash player is launched by FF, but flash games just hang and will not play. Flash is version 32.0 r0, the latest available.

I have a 2nd Laptop that has not yet updated to 65.0 and I have disabled the auto updater while waiting on seeing if the problem can be resolved.

Thank you for any suggestions, Tony D.

When I open Firefox which has Bing as my home page, a second tab opens at the same time moz-extension://c0e161a1-9167-4c3e-a8cc-38e5dba6b027/newtab/newtab.html. How do I stop this second tab from opening?

For some reason, when I click on the search bar, all my search engines have disappeared. There's now just a handful of engines, including "Twitter" which I've never added myself, so I presume this is a default setting.

Could anyone please tell me how to restore my search engines, if possible?

I changed background inadvertently when something popped up on my screen and I liked the way it looked. Now I want to change back to white background because with the black, some photos and videos have unnatural color. When I click on colors under fonts, the text is black and background is white, but it just the opposite on my screen. What can I do?

I've just found that if I do Ctrl + mouse wheel, the page now zooms! I've used Firefox for about 15 years and never had this happen before. The only thing that's different today is that I have just uninstalled Flash?

How do I disable this? I have always used Ctrl+mouse wheel to control the volume. For me, it is essential to be able to quickly adjust the volume with the mouse wheel, and very frustrating not being able to!

I am trying to delete bookmarks from Firefox on my MacPro. The instructions call for clicking on "the star". There is no star. Everything on the menu line has actions to do everything BUT delete a bookmark!

If I'm in Firefox and want to print an editable (to highlight) pdf page, I go to "Print" then choose either "Microsoft Print to PDF" or "Wondershare PDF element". What is displayed is never right. It may show the 1st page . . but not the rest; or nothing at all. I was going to try "Nitro Pro 12" but it appears that there is no way to install its "plug-in" now with Firefox.

    The end I want to get to is to have the ability, from within Firefox, to convert or "print" a pdf, that is editable, and will allow highlighting, from the webpage HTML.  It would be nice if it could be done, all at once right from the browser, without having to go through multiple steps - like taking a "screenshot" then uploading that image to some other site - which has also had unsatisfactory results (each "step" having the potential for some other unforeseen screw up or incompatibility).  I've spent a lot of time searching and can't find anything.
    Any help would be appreciated.

Firefox used to be a GREAT tool. Now, it is LESS than great. Firefox previously would load a web page in very short order (never really timed it) but it was in seconds. NOW it is more like MINUTES and that is just when it starts to indicate the page is STARTING to show itself on the screen. Has YAHOO insert itself into your programming?

I have enabled flash on the Flash Player Settings Manager. When I go to the site and try to access the controls, they do not populate with information completely. It works on every other browser but Firefox, so it must be a Flash issue with firefox. I'm using Firefox 65.0.2 64-bit on Windows 7.

Thanks for any suggestions!

I get fed up with the Captcha app asking me to identify traffic lights and such. I want to get rid of it. I have tried Malwarebytes but it does not solve my problem. Any ideas?

I use my organization's own FFsync server and wanted to set up sync from a new Firefox installation.

There used to be a setting where I could determine what server I want to use for sync. In my current FF version I can't find this setting anymore.

Thanks for help in advance! AnkeB
