Hello,

I'm not able to upload files to certain websites using Firefox on Android.

When selecting a file for the phone's file manager, the file upload simply not starting.

However, Firefox on iOS doesn't have that issue.

Firefox version used is the latest one and it is the one from Google Play.

Tried another browser and it works great.

I've had thunderbird running on my desktop for many years. I tried setting it up identically on my android and it doesn't work. I'm not sure what I'm doing wrong as I run the server side as well. How do you get thunderbird to accept no username or password for the outbound server? I'm using postfix and it only accepts outbound email from my ip address.

I have been dealing with problems with Firefox and YouTube for a long time. Every time I open a YouTube video in a new tab it would always give me this grey screen that goes away after a long time waiting.

I have tried:

• Refreshing Firefox
• Reinstalling Firefox
• Troubleshoot Mode, which the problem persist in troubleshoot mode so its not an addon
• Tried creating a new profile
• User-Agent Switcher which doesn't work all the time.

I want to avoid going chromium-based browsers but this is making me consider.

I have set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE in both Thunderbird and Betterbird.

I have created the file C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css

I have successfully entered css into that file that work as expected in Thunderbird v115.12 and has for the past several versions. But I have NOT been able to do anything in that file that works with BetterBird. In fact, using the inspector, I don't see userChrome.css even being loaded! I have also tried starting the file with '@namespace html url(“http://www.w3.org/1999/xhtml”)' but that makes no difference either.

How do I get BetterBird to recognize the userChrome.css file?

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

hey all. i'm inquiring about how much longer it will be until the URL bottom left corner of firefox on youtube.com bug i reported here is fixed: https://github.com/webcompat/web-bugs/issues/135606 . asking here because i asked on the issue page (the link) and nobody responded :(. thanks so much!

When a user opens hh.ru / headhunter.ru (famous HR portal in CIS countries) in Firefox, and then opens dev panel and tries to interact with it, especially with the code inspect tool, the whole browser stops responding.

The problem persists even on a clean Firefox profile. Other browsers (Chromium-based) work well with the dev panel on the hh.ru site.

For the past couple of weeks I have been getting the "Hmmm, We're having trouble finding that site" error screen quite often from both searches and links from other sites. It's always happened once in a while but it hasn't been anything bothersome. However recently it has become quite bothersome because it's happening a lot! However not all the time. It's not completely broken, just mostly. And it's happening while trying to visit sites that I know and visit frequently such as Amazon, Ebay, and even sites for local businesses that I trust and know are working. I'm not having any internet issues with my home wifi, nor am I having this issue with other browsers. I have however also noticed it on my Firefox mobile browser as well. I posted about this a few days ago and got some email back about an issue with my post. If this happens with this one and I'm unable to get this resolved I will just get rid of Firefox on my devices. FF has been a long time favorite and is usually set as my default browser but if stuff like this is going to continue, I can change that real fast. There are plenty of other browsers that work just fine and have decent customer support.

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

So I do not have the settings for cookies or history to be cleared i disabled that and I made sure it should save but no matter what I have to go through the struggle to sign back into everything. I've tried every fix like making a account then signing out or changing the settings nothing has worked. It's really annoying if anyone knows how to fix it that would be great

• Firefox 127.0.2 (64 bit), Windows 10, all extensions disabled.
• Tested also with a clean portable version (same Firefox version).

In private mode, on Google Images, large images (in the preview pane: if you click on an image in the search results) are sometimes (but not always) blurry. This is not the case in the "normal", nonprivate mode.

It works fine on Android, and other browsers also work fine. I have had this issue for a very long time now, but only now realized that it's a private-mode issue.

Example, which is reproducible for me: Search "site:linkedin.com new york" on Google Images and pick an image with a sufficiently large resolution.

I really like FireFox mobile, but the amount of misspelled words is starting to become an actual problem for me.

I use a Samsung S8 with Android 9 and whatever predictive text functions it has are turned off because I find them beyond grating and it's just not how I check for spelling errors.

The reasoning to this function being ommitted was (last time someone asked the question) due to space.

Why can't this be an official plugin that people can add?

I'm supporting FireFox entirely for ethical reasons (the only non-chromium browser that still cares about privacy) but I just can't type like this anymore.

Will something be done about this function missing?

My outgoing email stopped working suddenly. Incoming email works fine. I sent an email with a large attachment. It sent but after that I could not send anymore emails. I checked my password and server settings nothing has changed except I can't send email. I get a pop up window that asks for my password but after entering my password and hit enter I get another pop up window that says login failed please enter new password. The password works fine when I go AOL mail and enter it.

It has stopped working. Starting 2 weeks ago, Thunderbird keeps saying "Login to server imap.aol.com with username stuart_jones@verizon.net failed." I don't know what to do.

I've been using Firefox since the very beginning, and try to contribute to support it and Thunderbird when I can. But today, in order to get messages from my health care provider at Kaiser Permanente -- kp.org -- and get a document I needed for physical therapy, I had to sign in via Microsoft Edge in order to log in to my member account. On my Windows 11 Pro computer, I kept getting the message shown in the attached screenshot = "this page isn't redirecting properly".

I WAS able to sign in to kp.org from my mobile phone, but couldn't download the document from there. But at least I was able to send an message to my doctor asking them to send me the document via snail-mail.

At first I thought the problem was the Kaiser web site (which admittedly is pretty gawdawful). Didn't have time to pursue it last week, because I was attending an all-day class Mon-Fri. Finally today, when I got the same Firefox error message, I tried to access kp.org via Microsoft Edge. Sure enough, it worked.

Then I searched Mozilla support, and found a closed message thread indicating that the problem had theoretically been "solved" by some sort of programming fix as of June 12th or thereabouts.

I do NOT want to switch to a browser maintained by Monopolists'R'Us. I still bear a grudge because about 30 years ago they killed or marginalized two of my favorite programs (Lotus and WordPerfect) by giving away Excel and Word for free with Windows. Even if I LIKED Microsoft, the default user interface is cluttered with too many cutesy-poo widgets and AS (artificial stupidity) "help" that I do not want. But I'm an old lady (84), and if I need to communicate with my health care providers, I will have to use whatever method works, no matter how much it galls me.

Hope you guys can find a fix to this problem that works for EVERYBODY (including me). Thanks for your attention.
