Problems since Thunderbird updated (automatically?) to beta version (63.0). Unable to send from one of my two companies' accounts, despite having been in ongoing communication with their tech support (STARTMAIL) that my settings are correct. They were correct. But now "Account Settings" are not visible (just a tiny non-functional window) unless I got to Help > Troubleshooting Information where they are merely viewable (see below).

Finally, I uninstalled Thunderbird via control panel on my Windows OS. Then I downloaded (from Mozilla website) Thunderbird version 60.2.1.

It opened with the same issues--unable to send via one account; unable to view under "account settings" the details for any of my accounts. Verified with my optimization software (System Mechanic) that 60.2.1 was the only visibly remaining Thunderbird artifact. Did hard shutdown of computer. No change upon re-starting computer.

I had expected that uninstalling and downloading the prior version of Thunderbird would mean that I would have to go through registering in Thunderbird my various email accounts. I thought that I could do this cleanly (all w. IMAP) & more efficiently (no duplicates or leftovers--seven accts on 1 server; one acct on other server). However, Thunderbird opened already populated exactly as I had it (even open tabs) prior to uninstalling.

The only tweaking I have done this week since Thunderbird updated to beta version were: re-set my Master Password... attempt to change the accounts on one server (my ISP's) from POP3 to IMAP (which doesn't appear to have stuck as IMAP, despite speaking to their tech support), but those accounts appear to be working... deleting and re-instating 3x my email accounts with the other server (which is IMAP) due to the problem of not being able to send email's (I have been in ongoing contact with their tech support)--each time applying the new password provided by my server.

BTW, earlier in this process I contacted my antivirus tech support. And I've tried sending with my antivirusware shut off, but login to the server still failed.

Help, please!

I have researched endless options how to download an add on for google search in the options dropdown menu for search engines.

The download https://addons.mozilla.org/en-US/thunderbird/addon/google-search-for-thunderbi/?src=search says it is not compatible with my version of thunderbird which is 60 Beta. What must I do?

I wanted to try thunderbird 60 (60.0b6). Fresh install with a new profil.

And I can't find the "quick reply" option (the quick reply field that allow to quick reply to an email, like in the regular version of thunderbird 52.8).

How do I turn that on ?

Thank you.

i want recent beta version of Thunderbird to work in background & shows new message arrival notification icon in win-10 tray. is it compatible for this. if Yes, how to do it, If No, is the team working on this, can we get this facility in future?

I'm running on the beta channel on one machine and release channel on another. The release numbers are far different. Does that mean that what I'm seeing in beta is years away from release?

How can a change the order of email accounts in my left pane? https://addons.mozilla.org/en-GB/thunderbird/addon/manually-sort-folders/ only works through 57.0. I am running 60.0b1

Hello, I currently use TB 52.6.0 as my main email client. I would like to test/tryout TB 58 Beta 3. Is it possible to install TB 58 Beta 3 and continue to use TB 52.6.0 as my main email client? In other words, will TB 58 Beta 3 automatically upgrade/replace TB 52.6.0? Thank you, R.V.

Never really bothered asking. But now i think it's time. Why is it, that Firefox, never, ever, remembers it window size or position?

1. I use Firefox exclusively in fullscreen. Every time, after i've started my pc and launched Firefox, it never starts fullscreen.

2. I use Firefox in windowed mode, i resize and place it where i want it to be. Every time, after i've started my pc and launched Firefox, it never remembers it's size nor position on the desktop.

I do not understand why that's a thing.

Pc's: multiple win11 machines.

Hello Firefox Support Team,

I would like to report a browser compatibility issue regarding CSS positioning behavior that differs from Chromium-based browsers.

• • Issue Description:**

When an element with `position: sticky` is placed inside a container with `position: fixed`, Firefox treats the sticky element as if it has `position: relative`, effectively breaking the sticky positioning functionality.

• • Expected Behavior:**

The sticky element should maintain its sticky positioning behavior even when nested inside a fixed-positioned container, as it does in Chromium-based browsers.

• • Current Firefox Behavior:**

The sticky element loses its sticky properties and behaves like a relatively positioned element.

• • Use Case:**

This issue particularly affects modal implementations where: - The `body` element receives `position: fixed` to prevent background scrolling - Page elements (such as `.total-section`) should maintain their sticky behavior regardless of changes to the body positioning

• • Browser Comparison:**

- **Chromium browsers (Chrome):** Sticky positioning works correctly in this scenario - **Firefox:** Sticky positioning fails and falls back to relative behavior

• • Request:**

Could you please consider aligning Firefox's behavior with other major browsers? The current inconsistency creates cross-browser compatibility issues and forces developers to implement JavaScript workarounds.

Thanks!

I don't need to pin tabs, ever. Every time I try and drag a tab to the first slot, it always pins the tab, and I don't want it to do that. Is there a way to disable this stupid feature?

Firefox used to start in a second on my Windows 10 PC. But lately it now takes about 10-20 secunds to start (on 143 beta). Is there any reason why it takes so much longer to start now? Is there any setting og tweak I can do to get it to start faster?

I'm using Firefox Developer Edition 143.0b5 (64-bit), running on macOS Big Sur (11.7.10). My bookmarks for Facebook, Instagram, and Threads won't load on the first click. Most of the time I am presented with a blank white page. Sometimes I might get part of the page to show. I have to click on the bookmark a second time and then the page loads completely. This behavior doesn't happen with any other bookmarks I have.

Anyone know why this is happening?

This seems like a relatively new feature that I don't see a setting to toggle. How would I disable the drag-and-drop area at the top of the vertical tabs which prompts me to pin the tab?
