I'm getting Secure Connection Failed error on every single website I try to visit. Including sites such as microsoft.com, duckduckgo.com, google.com, etc. (Strangely, mozilla.org works fine.) Try Again never works, and Advanced - Accept risk works sometimes, but not always and if I close Firefox app and re-open it's back to the error page. I can't believe this is a common problem, so there must be something about my phone that's causing this. Android 11. Happens whether or not WiFi is enabled. What could it be?

Hello, I've followed Firefox's invitation to install and update the browser on my Mac. Unfortunately the new version is not compatible with OS 10 El Capitan, my operating system, so now I can't use Firefox at all. How I do get the old version back?

Thank you, Lars

The background color on the screen for composing a message is black, and the text is red. This happens for when using "Write" to open the composing screen, or using a template to compose. Even though the background and text during composition is black and red, respectively, the sent message is on a white background with black text. I would like the screen for composing the message to also be white text with black background and for those to be the default colors. Thank you.

Version 68.12.1 on Windows 10 I know the exact subject of the email, I have sent it to myself a month ago. I type "upgrade m1" with quote marks on the top global search bar and I get all kind of junk with the word "upgrade" that are mainly spams. If I scroll back manually I can locate the email with the same subject in my inbox. I have rebuilt the search cache already.

Any suggestion?

After the most recent update, 78.4.0, I cannot receive emails. I can send emails. Also the folder icons changed from yellow to white. Erols.com (RCN) is my email host. I can still receive emails on my phone and through mail2web.com. I have tried turning off firewalls, both Webroot and the native one in Windows 10. I have tried uninstalling and reinstalling both latest version and an earlier version. I checked to make sure the proper password was still saved. When I hit the Get Messages button, there is a "Connected to pop.rcn.com..." in the bottom pane where the "unread" and "total" are listed. It just vanishes after a bit. Anybody got a cure?

I am using Hotdocs portal, which is an in-house document assembly tool. Firefox is the recommended browser, but it is recently handling 2016 docx files incorrectly. When we choose a file on the portal site (internal site), we go through the interview and are presented with a link to "download" the assembled file. When you click that link, a pop-up appears showing the file name as abc.docx but then says it is a Word 97 - 2003 document, even though it is not. The original template is not. If I choose to open the file, it ends up opening and showing as abc.docx.doc If I save the file, instead of opening it, it saves as abc.docx.

If we run this same process in IE/Edge, the file opens as abc.docx as it should. I have uninstalled Firefox and reinstalled. Is there anything that could be causing this? I've tried a bunch of troubleshooting steps and nothing seems to change this outcome.

Thank you.

I use html pages on an internal hard drive that link to pdf documents. For some reason since Version 91.0.2 was installed I can not get the pdf documents to open with Adobe Acrobat Reader DC.The new version insist on opening the pdf's in the Firefox web browser. When I click on a pdf link at an external website the files will open in Adobe Acrobat. I used the code below to test the open in Adobe Acrobat execution and it works on the w3School example. When I run it strait from my hard drive the document opens in the Firefox web browser.

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
  </head>
  <body>
    <h1>PDF Example</h1>
    <p>Open a PDF file <a href="datasheet_cube-model-715.pdf">example</a>.</p>
  </body>
</html>

Please let me know if there is a solution. Thank you,

I have been using a very old version of Thunderbird (3.1.20) and I now need to move to the latest version. I am hoping it will be possible to migrate the old profile in its entirety, with folders, stored POP mail, addresses and accounts to the latest version. I understand about editing profiles.ini to point to a backup copy of the old profile instead of the default profile, but I am not sure if the profile structure has been changed in later versions. Would I do this using the Profile Manager? Does it allow you to browse to a Profile backup location?

Also the existing paths in profiles.ini now seem to have slashes rather than backslashes. Is this a change I have to make in the editing of the path to the old profile I want to use?

Thanks for you patience. Dave

Automatically received the latest major firefox update on my Samsung galaxy tab s3. I don't know what Mozilla did to this release but I can't find any functions to do basic browser controls like going back to the previous page, going to the next page, or refreshing a page. I really love firefox but it's kind of unusable without these controls. I'm going to have to use chrome which I'd prefer not to do until this is fixed. Any help would be greatly appreciated!

I wanted a phone no. so I could call. Today Thunderbird decided to no longer accept my password and there is no route for getting to Thunderbird to find the problem or get another accepted password. Bruce Lowrey. brucelowrey@comcast.net, but it does not work since Thunderbird is not accepting my password. 816-254-8105

After installing new version of Thunderbird I am getting completely blank Thunderbird screen. This occur few times before while I user versions lower than 68, but after restarting it was OK. After update to version 78.4.0, first starting is OK, but after that I am getting completely blank screen. Only thing that works is: click at top left corner and only drop down File menu appear, move mouse to place where Help menu should be and it appear, then click on Restart with Add-ons Disabled and restart in Safe mode. Safe mode is working OK. I have tried uninstalling all Add-ons and start normally but I am getting blank screen. I am using Thunderbird Portable. I have copied Thunderbird Portable completely to other computer, updated it to 78.4.0 version, it was OK, and copied it back to my computer. That worked. But when I updated to 78.4.1 I got blank screen again. I am using Windows 10 running on Parallels virtual machine on MacBook Pro, anti virus is ESET. I managed to revert to previous state by using Parallels snapshots, but I would like to solve this issue. Another person in my company has this problem, also running on Parallels.

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)

When I use Firefox on the external monitor, I set the zoom level to 150%. When I leave home a take my laptop with me, I set the zoom level to 100% to use with a smaller screen.

I want to automate setting the zoom level.

Is there a way to programmatically set the zoom level from a script? Does Firefox expose such an API / command-line tool?

Thanks!

I downloaded and installed the firefox app and nothing happens. No menu. No tabs. The word "firefox" appears in the upper left corner of my screen and a "." appears under the app, indicating that it is open. The screen "blinked" momentarily when I opened the app. I am a longtime user of Firefox and this same thing happened this morning when I opened the app, which I uninstalled, and then downloaded and installed this new app. Same problem.

Yesterday when I installed the 96.0 update it has forced my background color into a dark grey and ignores the background color setting. I would like to know if there is a setting, add on or update that can return this to normal. The theme I am using has not been updated in 2 years so I am fairly sure the update has caused this.
