Running Thunderbird 140.8.0esr 64bit Windows 11 Home, v25H2 932GB storage 32GB ram i7-13700k

Recently, I've started getting the following message every time I launch Thunderbird: "The certificate for imap.googlemail.com does not come from a trusted source."

Digging into details I get: "you are about to override how Thunderbird identifies this site" "Location: imap.googlemail.com:993" "This site attempts to identify itself with invalid information" "Unknown Identity. The certificate is not trusted because it hasn't been verified as issued by a trusted authority using a secure signature."

Digging deeper into the certificate I find the issuer is Bitdefender who I use for antivirus and VPN. However, the VPN shows no effect when enabled or disabled. The validity period is 2 Feb 2026 to 27 Apr 2026

l can get email, but cant send it. Is Bitdefender at fault?

I'm stumped. What should I do???

I use Free Download Manager v3.97 along with FF Free Download Manager extension v3.22 to download files from Easynews.com. This issue may have nothing to do with Firefox except that the problem started a couple of days ago about the time 1.46.0 was installed.

When I right-click to download a video file, FDM is configure to automatically start the download. But downloads are not starting automatically now. FDM just shows the download with an hour glass figure. I have to manually stop then start the download.

When adding my outlook account to thunderbird, my right password is regarded as wrong. I don't why. I've checked the password several times, and make sure it is right.

Linux User So. I recently followed a Mozilla guide, previously posted, and something that I did, or changed, I now have a very annoying "profile" name in the title bar. Further to that, I now have an additional menu option called "Profiles", with --"profile --Add Profile

Manage Profiles

I have never had or seen these items, except when I've moved my profile from an old computer to a new computer, using the console of "firefox -P" command.

It is becoming very annoying as I only have one profile, and I don't want an more.

Question. How to I block the display of 'profile information' ? Thanks

After tried many suggested steps to trouble shooting the problems, it still can't download Comcast emails. It keeps pop up "enter password" or "password failed" again and again. But I can send emails. I can't upload the trouble shooting information file to send. Thanks

Is there a setting to always show the translation icon in the Firefox desktop address bar?

1. Scenario

I'm visiting a website that is not in my native language. For example, I natively speak English, and the website contains Spanish text.

The Spanish website incorrectly sets lang="en" in the HTML. Here's an example: https://animalessinhogar.com.uy/

My browser's default language is set to US English. When Firefox sees the Spanish webpage declaring the lang="en" tag, it assumes the webpage is in English, and hides the translation icon from the address bar.

1. Issue

The end result is I see this website in Spanish, there's no translation icon in the address bar, and also no way to force a full page translation. The best I can do is select parts of the text, right click, and ask for "Translation Selection to English". This gets very tedious, especially when I have automatic translations for Spanish websites already turned on (browser.translations.alwaysTranslateLanguages = es).

1. Proposed solution

To work around these websites which mis-declare their language, is there a way to always show the translation icon in the address bar?

I had also thought of removing my browser's default language, so that the translation icon would always appear on every webpage. However, that would mean that websites that present different versions based on browser language wouldn't display my native language at first, or might not work at all? So this seems like a less good solution.

1. Firefox details

140.4.0esr (64-bit) running on Debian Linux 13 (Trixie)

Here's some related Firefox config options for translations, and their settings on my browser. I think I've only changed the configuration option to always translate Spanish webpages.

I had to restart my Mac. When TB restarted during relaunch of the Mac, it was like TB starting fresh. It didn't display my email accounts, or my folders with saved emails, etc.

I quit TB and looked for it in my Applications folder - and I found two versions of TB. Inside the Thunderbird folder was version 140.9.0esr. Outside the Thunderbird folder was version 150.0. See attached screen grab.

I thought I should try launching the newer version (which was outside the folder). So I moved the 140.9.0 version to the trash, then launched the newer version – and it had the same problem. It looked like I was starting TB from scratch.

Next I quit TB (the newer version) and moved the older version out of the trash and back into the TB folder and double-clicked on it. A dialog box popped up saying that the file is damaged and can't be launched.

So I tried launching the newer version again, and it still looks like starting from scratch.

I really hope somebody can help me solve this. I can't access any of my email accounts or any of my stored emails. I use email for work (as most of us do), so this is crippling me.

Thanks in advance for any help.

Whenever I type in "photo", Firefox has always autocompleted to photos.google.com. Today it's started autocompleting to photoquotes.com instead; a site I never use, and I don't know why Firefox is suggesting it.

I have followed SEVERAL guides for how to remove sites from autocomplete suggestions, and all of them give wrong advice.

I have gone to History/Manage History and 'Forget about this site'. That does not remove the site from autocomplete.

I have tried 'Hover over the entry to select it, then click delete'. This does not work. It only deletes the last character entered in the address bar.

I have tried 'Select the three-dot menu beside the suggestion and select Remove from history'. That is Not Possible with the top result in autocomplete, which appears above Firefox suggestions.

Could someone please tell me the CORRECT answer on how to remove specific websites from being suggested in autocomplete!?

'bold text'create new email and type name in address box and no email address shows up ALSO, SEARCH ON THE SIDE DOES NOT SHOW THE ADDRESS WHEN YOU DO THE SEARCH.

I access Bluesky (bsky.app) for business on my PC. Since the last update, I've been unable to access Bluesky from my regular Firefox browser. I can using other browsers, the mobile app, and, oddly, in Firefox private browsing. I've cleared my browser history, cookies, etc. I restarted the computer. I logged out of Bluesky (and now can't log back on the regular PC account because it claims I'm not connected to the internet). Yet, I had no trouble logging in using private browsing.

I've looked through settings, etc. and can't figure out what could be limiting my ability to access this website.

Hi, I am on Firefox version 150, but I can't see the new free VPN button. I wanted to try it out, but I can't see it anywhere in my settings. Any advice would be appreciated.

I was following https://support.mozilla.org/en-US/kb/built-in-vpn?utm_source=www.firefox.com&utm_medium=referral&utm_campaign=whatsnew-150#w_turn-on-vpn-in-firefox , but there isn't a button like it shows

When using Firefox mobile for android, a black bar appears at the bottom of the screen, above the address bar. Please see attached picture.

It only seems to occur when the "scroll to hide toolbar" setting is disabled. The bar moves upwards when using the keyboard.

Samsung galaxy s25 Android version 15 Firefox version 147.0.3 (Build #2016141759)

Please let me know if any more information is necessary.

Today is February 24th 2026. Sometime today Firefox (Android) just updated itself. Now there's stuff on top, there's stuff on the bottom, (home page, tabs) and I don't care for it very much. How do I go back to the previous version?
