Can't connect with the just downloaded version 66.0.4 to virtually any site - not to Google, not to NYT, not even to Mozilla - Firefox won't accept ANY certificate! Following errors appear (examples): "Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to addons.cdn.mozilla.net because this web site requires a secure connection. What can you do about it? addons.cdn.mozilla.net has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. The issue is most likely with the web site, and there is nothing you can do to resolve it. If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

Or: Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to www.nytimes.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. What can you do about it?

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

The explanation is as follows: Someone could be trying to impersonate the site and you should not continue. Web sites prove their identity via certificates. Firefox does not trust www.nytimes.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates. Error code: SEC_ERROR_UNKNOWN_ISSUER

No problems whatever with other browsers. I'm sending this with Safari.

Is it possible to remove favicons from the Bookmark Tool bar and bookmark pulldown menus? It'd be a much cleaner look. Not entirely sure, but it looks like someone was asking a similar question here: https://support.mozilla.org/en-US/questions/1258765 If by any chance pasting his contact here reaches @jscher2000 perhaps he has some input. https://support.mozilla.org/en-US/user/jscher2000 Thanks!

Is it possible to disable automatic "word search"? every time i'm on a page and hit some letter key mozila opens the automatic "search keyword" without my wanting it. I want to open the "search keyword" only when I press crtl + f and never, never in automatic. it also hinders to play browser games, I can not play games because any key that I press the mozila opens the "search word"

How can I do keyboard shortcut, "Text encoding options", then "Unicode". I have it on toolbars. Like on screnshot, I pint mouse, then I need to select Unicode, which is bothering. I am opening many many pages, which are always different than unicode.

When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

Everyone going to the above mentioned website experiences the same annoying reloads. Please add a method to Firefox like IE has that can restrict sites reloading, assuming this doesn't exist already. Thanks

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!!!!

Until several weeks ago, new windows created through Javascript with window.open() worked. We could pass the new size, and other features, e.g. menubar, toolbar, etc. and they would show up. As of v.76.0 this is no longer true. The parameters are ignored. If we use no parameters, the menubar, etc. do show, but we can't control any new window features. We have not changed our programs at all, and window.open() parameters still work correctly in Chrome, Brave, Edge, etc. How do we get Firefox to recognize the window.open() parameters (again)?

Hi, I'd like to get rid of the status bar at the bottom left corner. I know it goes away and it seems impossible to remove. But is there any way to remove it? I add an image to show what I want to remove. Thanks in advance!

with the planed removal of FTP support from Firefox I am at my wits END... I cannot seem to get FileZilla to connect to ftp.mozilla.org what connection type should I select and WHAT port number am I suppose to be using? anonymous login is fine right?

I am unable to get the 'recommended by Pocket' panel to appear in new tabs with my normal user Firefox profile (Firefox account sign-in) on Mac Catalina. When I go to about:preferences#home the option simply is not present.

I created a new user login on my mac to access banking and other financials. This uses a separate Firefox profile (including new Firefox account sign-in and email), and the 'recomended by Pocket' panel is present.

The panel is present on new tabs opened for my normal Firefox account sign-in on my iOS (iPhone) Firefox install.

The about:config settings searching for 'pocket' appear to be the defaults, and match the settings in the financials account.

I have tried in 'safe mode' (add-ons disabled) and have done a Firefox 'refresh', however my add-ons (and presumably everything else) were restored when I signed back into my normal Firefox user account.

Hovering over the Pocket icon in the address bar displays 'save to Pocket', implying to me that it has signed me into Pocket. I've signed in at getpocket.com. New Firefox profiles without signing in do not show 'recommended by Pocket' in either new tabs or the about:preferences#home configuration page, but I expect the functionality requires being signed in to a Firefox account.

Help or suggestions much appreciated.

When I try to watch a video on WSHH, I get this error VIDEOJS: ERROR: (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) No compatible source was found for this media. I have DuckDuckGo Privacy Essencials installed, and I also have uBlock Origin installed. I disable both extensions but I still see the same error. I'm on Ubuntu 20.04 LTS, and my Firefox version is 77.0.1 (64-bit) canonical - 1.0

I attach the console log.

Is the Help menu the best way to submit feedback to Mozilla? Does anyone actually read it? I've submitted feedback that way before but it feels like no one saw it.

You don't even get a "sent" confirmation - all I get is a page saying something like "Your feedback will be used to improve Firefox", which doesn't confirm the feedback was sent!

I actually sent feedback about this last year, saying that the "sent" message should be clearer. But who knows if anyone saw it! LOL

Plainly speaking, I don't like the new address bar, how it auto completes my searches or the results it pulls. I didn't like it when it was defaulted to being on starting with version 75 but I was able to easily switch a few setting in about:config to fix it. Those settings no longer affect the address bar as of update 77.

The settings I had changed were:

browser.urlbar.openViewOnFocus browser.urlbar.update1 browser.urlbar.update1.interventions browser.urlbar.update1.searchTips

which were all set to false. I saw that setting "browser.urlbar.disableExtendForTests" to "true" might be the solution but, while it does stop the address bar from expanding when using it, it also stops it from expanding at all so the websites that would come up from searching can no longer be seen either (they are still called and using the down arrow will let me scroll through the results, I just can't see any of them). It also doesn't fix the results issue which I would say is the most important.

I would like to know what I need to do so that: 1. The results it shows me are no longer based on frequent visit (basically, the pre-update search system, as is they are scattered and look messy, pulling many different sites in a seemingly random order and it's not particularly useful) 2. It no longer autocompletes results (IE. "F" autocompleting to "facebook.com", this is always something that has bothered me regardless is context) 3. It no longer pops out/expands when in use (admittedly this is mostly an aesthetic issue but I still don't like how it looks)

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.

Hello helpers! I have lost my bookmarks and several add-ons after latest install (77.0.1). I can't find old profiles to use and restoring to an older bookmarks backup doesn't work either; I get an error message "unable to process the backup file - but it does at least see the last relevant version from 10.6.2020.

To compound the problem, whist working my way through several solutions offered on these forums, I hit the Refresh Firefox button, which created an Old Firefox Data folder on my desktop - but seems to only contains the new stuff after today's upgrade) AND I also reset my Firefox password and got the message that Personal Data will be lost so that has added to the problem. Basically a massive mess!

Can I revert to the older Version of Firefox or using an old computer backup or is there another way to fix this?? It's nearly 3000 bookmarks going way back to 2014 - I'd be gutted to lose it all.

I appreciate any help - thanks in advance! Nicole
