Secure Connection Failed! It is continuously checking mail server capability. I have an authentication problem with Thunderbird since the update yesterday 102.8.0. It was working fine before that, but now I can't receive emails, but I can send them.

Secure connection failed The document contains no data.The page you are trying to view can not be shown because the authenticity of the received data could not be verified.

   I have checked the IMAP with my protonmail and it is correct - nothing has changed there.
   I have gone into my Virus protection and cleared the caches etc.
   I have gone into tools and cleared recent history.
   i have read through rheems of articles and suggestions on the Mozilla page - but cant fix this problem.

The last email I received was from a regular friend - but an error message came up suggesting that their email/server could not be verified - I clicked to make an exception. I don't know how to get back to this place to undo this exception - in case this is the problem.

I export all my passwords to usb, went to other computer and ........................... needed a 2e browser (edge) to import them?? How to import passwords from usb-stick to firefox? Is this even possible? i cannot find anything to import them.!

I autoscroll, using the middle mouse button a lot. I middle click, release the button, and just move the mouse. To stop the scrolling I click the middle button again.

The problem is that in Twitter (only when using Firefox, not Chrome), and perhaps a very few other websites, if I make that second click (to end scrolling) over a link or linked image, the link opens (in a new tab). This is very frustrating, since I can move the mouse anywhere while scrolling, and I commonly mistakenly open links this way, interrupting my reading.

If I am *not* autoscrolling and middle-click on a link in Twitter, nothing happens. (Perfect!) But if I am autoscrolling the link opens (Bad!).

How can I set up Firefox to that the middle mouse button will never open links, and only function for scrolling?

For the last several FF versions, although I choose a light theme, the pull downs/menus always wind up dark with white text. It also shows up when I am editing options in FF itself. How do I stop this? I want a light background with black/dark text.

For the last few weeks I keep getting this error message: An error occurred during a connection to ....... You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

It will suddenly happen for multiple sites that I have been connected to in the past, or new sites I try to open including support.mozilla.org. A solution is to clear my history and restart the browser. It only happens on my windows 10 laptop. I think happens when I have logged off or the device has slept and then firefox has restarted and opened previously open tabs. Other devices on the same network don't get effected.

I am running Firefox 100.0.2 64 bit and now after literally years of visiting https://www.metrobyt-mobile.com/ to pay my mobile bill every month, it won't open the page. [See image of error]. I have gone into settings | browser privacy and tried turning off blocking for cookies, tracking content, cryptominers, and fingerprinters. No difference. I have gone into Enhanced Tracking Protection and clicked on Manage Exceptions and it won't give me an option to add the website. The site opens normally in Chrome. I find the instructions for "What to do if a site seems broken", but there is no shield or broken shield next to the web site address to click on. [See second image].

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Up until Firefox 64, Firefox had limited support for RSS:

• Viewing a RSS feed would show you the feed items, with an option to do something with the feed.
• Live bookmarks would actually subscribe to those feeds

I can understand removing Live Bookmarks. It's a big feature. I don't understand removing the (what I assume to be) XSLT stylesheet that made RSS feeds not look like a wall of XML. Does anybody know what the conversation was here? Are there minutes?

Even basic RSS support helps people interact with the web, and since Chrome and Firefox both dumped RSS, users are being driven further and further into the arms of "Platforms" who handle this stuff through black-box algorithms. And so much tracking.

Mozilla should reverse this one. Bring RSS back hard.

Hello! After updating to the latest version of Firefox (100.0.2, 64-bit), I notice that Google search stops working every now and then. By stops working, I mean I can't use their website https://www.google.com or search using Firefox's address bar or search bar. Searching with other search engines like Bing is working normally. In order to get Google search working again, I have to close and restart Firefox. However, after some time, it stops working again. How can I fix this problem?

I was browsing a site when suddenly most of the text got almost unreadably small. I was just scrolling and I don't think I had my hand on the keyboard so I don't think I accidentally activated a shortcut. I checked on another site and I noticed it's now a different font than it was before. I tried reloading firefox and my laptop and it didn't change anything. What did I change? My default font setting is lora, which isn't the font things have changed to

Is there any way to reorder the URL bar back to how it used to be in older versions of firefox?

It doesn't make any sense to prioritise google search over bookmarks.

Is it possible to go to the older style where search is at the bottom and only becomes the priority match when nothing else can be found.

"Search suggestions" are disabled. Autofill is also disabled. The problem also occurs on a fresh install inside a VM, so I doubt it has anything to do with userchrome/about:config

Thanks.

Is there any way (as in Thunderbird, via layouts.css.devPixelsperPx) to enlarge everything on a given monitor/display/colorDepth setting? Or an approach using userChrome.css that impacts everything, not just displayed text in the browser. Yes, this is a "tired old eyes" (excessive nanoseconds spent looking at bigger and bigger displays with higher and higher resolution) type question. My setup is multiple boot OS including Windows 11, Ubuntu, Manjaro, Arch. In each Firefox is the default browser, but Chrome and Edge seem to have more fine-grained controls for managing the chrome display than Mozilla. Using the latest 64-bit Firefox (100.02) if that's helpful.

Hi, for me the most intuitive behavior for creating new tabs is to insert after current when using the keyboard shortcut, and inserting at the end when clicking the plus sign at the end of the row. I'm making the switch from Chrome and the Open New Tab Here extension enables this distinction. Curious if there's an existing solution, or would an additional config setting be required?

Since the Firefox 100 update, I have had issues with Firefox connecting to Google and its subdomains. When the browser is first started, all google domains work fine. After a few minutes though, a dialog at the top of G-mail (multiple accounts) appears stating it wants to re-connect, and will try and reconnect indefinitely with no success until the browser is closed and reopened. Also, calendar will stop working, and attempting to connect to any other google service (search, keep, drive, etc.) results in no DNS resolve, with sometimes the search bar URL changing to "about:blank." I have tried resetting the browser and re-installation (both at a user and administrative permission level) with no avail. Is this a known problem, or is it suspected there is another culprit here? It is worth noting that this is my company laptop, and that my coworker has also recently began running into this issue.

Thanks!

During an online transaction I get into a loop where Firefox reports "Firefox prevented this page from reloading automatically". I respond with Allow but the situation repeats. I have changed the settings to standard for this particular website, but the problem persists and appears to be the reason that the transaction eventually fails. What other settings or adjustments do I need to make to allow Firefox to automatically reload a page on a trusted site?

I cannot find the right thing to change in about :config to stop the address bar stealing all my searches, it is quite irritating. I have just bought two new computers and on first I managed eventually, but have been 8 hours trying to figure it out ( as in what I did before) I am not tech savvy so only managed before by searching info online. Can anyone help with this ?

Up until the latest updates a week or two ago, UPS tracking worked fine. However, with version 100.x, UPS stopped working. All is get is the error message, "We are unable to complete your tracking request at this time. Please try again later.". I tried other older tracking numbers that I know are good, and the same error. However, UPS tracking using Chrome or Explorer/Edge works fine.

I could blame UPS, but both Chrome and Explorer/Edge does work.

Apparently, Firefox is sending a (buggy) request that UPS doesn't like.

Thanks, Bill

latest browser shuts down when I open a new session. After a few seconds it shuts off, I reopen it and its ok until the next time I open my notebook. The without fail it happens again. Began I think with the last update on a Windows 11 notebook.

One site in particular shows me an Error 520 when I try to open it. I am able to open the page with tablet and phone but not this new laptop. How can I eliminate the problem-Cloudflare?

Hi I have been experiencing rejection of access to many legitimate Web Sites. I have attached the error I get even when trying to get to a mozilla web page. This is getting both frustrating and limiting in my desire to support, which I do, Mozilla's strategy of privacy and freedom.

I am using Fedora Linux Version 34 and Firefox Version 100.0.2 64 Bit. I did not experience these problems months ago. I have kept everything up to date as far as I can with my OS limits, if any.

I want to examine what is going on and would like to know where to look. Any help would be appreciated ... Robert
